  2. My grandpa bought a VW BEETLE brand new in February of 1959. He drove it every day until he had a stroke in 1984 and could not shift gears anymore. He gave the beetle to my dad and he kept until 1998. At that point dad the beetle to me and I still have it to this day. We estimate that the little beetle has had at least 5 engines. 3 transmissions. A dozen or so clutches. Hundreds of tires. I drive it when the weather is nice. Sometimes I look at it and I'm totally amazed. I can remember Grampa dropping me off at kindergarten in that little car, now I drop my grandkids off in it. Maybe one of them will have it someday. Oh I forgot to mention that we're pretty sure that it has well over a million miles on it.

  3. Of course a car made 120yrs ago appears primitive by modern standards, but if the alternative was having to ride a horse I'm sure even a modern motorist would be grateful!

  4. It's nice to still have a brand that does amazing things.

  5. Wow, that poor guy. What an innovative smart dude. It’s a shame he got hurt and disabled, but it is certainly admirable that he still made those motors and got them running!

  6. Gear driven camshafts. The ultimate in reliability and peformance. No timing belts/chains to break.

  7. They paid me one summer about 50 years back to drive a few of these around Greenfield Village, where they had a small fleet of them when some of the newer models were only about 50 years old. Brakes were always terrible.

  8. Your graphics, timing, rhythm, relative volumes, etc. make this a pleasure to watch. Anyone can read a script, not anyone can do it in a way that makes the viewer never once glance to see how much longer is left or be tempted to fast forward. Thanks.

  10. Normally a piston completes an up-down movement in 360 degrees. With this setup the top of the piston has an additional up-down movement in approx 60 degrees. So with the engine running at just above idle at 1000rpm this piston top will be moving back and forth as quickly as if it were 6000rpm on a conventional engine. It won't be able to rev up without enormous forces and consequent breakages to contend with.

  11. Horses at the time were also a viable option. They contained more moving parts but maintained themselves through biological repair processes. The horse ran on hay and grass which was plentiful and free. The exhaust, in the form of smelly clumps of droppings, were non-polluting and could actually be sold for use as fertilizer. A horse had approximately 1 horse power and four hooves which provided locomotion in lieu of wheels. Horses were manufactured by other horses, sometime several at a time, though it took at least two horses to make them. The downside of horses to automobiles was that horses needed to be kept on (alive) at all times, they needed to eat and drink even when not in use. They would also sometimes die and there was no way to bring them back to life no matter how much people paid the local horse mechanic. If a horse's hoof went bad it couldn't be removed and replaced with a new hoof, cars on the other hand could have their tires replaced if one became damaged or deflated.

  12. I've had a -59 B425 and a -79 2CV6, 605cc. Both absolutely lovely everyday cars. On twisty gravel roads I could keep many times more powerful cars behind me. The body roll wasn't a problem and all 4 wheels stayed on the ground at all times. The time I lost on the 'straights' I easily gained through the tight bends. Very annoying to some... They never broke down and I used them as my every day cars, all year round...even below -25C°, completely closed air intake and plastic foam sheets in the roof lined with corduroy fabric. There are so many clever solutions incorporated in this technically advanced car, that even formula one tech people know of them and refer to the 2CV regarding certain aspects. The whole story would take to long to tell here. Thank you for bringing the 2CV back into the limelight where it belongs!

  13. I actually own two Taurozzi breathing air compressors. They’re pretty neat.

  14. This is the kind of video that makes YouTube worthwhile.

  15. I've lost count of how many of these game changing engines are supposed to have been on the market by now.

  16. The T engine was bolted into the Chassis. The spark plugs were fired by flat uninsulated brass conductors, that were bent and so held themselves in place. The lack of fuel pump required it to reverse up hill. That reduced road grip. Drivers always needed water for the engine. The wooden spokes, in artillery wheels, might Take a long soak to swell and tighten up.
    424
  17. This looked like an engine with some serious potential, too bad it wasn't developed further. AND I LOVE YOUR ANIMATED ILLUSTRATION!!!!!! We need more productions like this!

  19. What a guy! While a simpler design is always preferable, nothing can beat the elegance and ingenuity of an overcomplicated mechanical solution. Even if it's not actually better, it's still a win for the fact he did this all himself. It's not a question of 'why' but rather 'why not'.
    264
  20. I am sure this is being done due to size constraints to operate as an apu range extender on EV cars. Operating at a constant speed would eliminate many issues inherent to this design in a conventional application
    260
  21. I remember being at a motorshow a few years back when the W12 was introduced. The guy on the stand explained in depth how it all worked and it was absolutely fascinating. Had a full scale cutaway model too. The W16 is like that on steroids. Tremendous piece of engineering
    254
  22. Wet belt is the worst thing corporate did to engines.
    230
  23. The rod system sounds quite interesting and I never heard of it. That explains why the little NSUs are still racing until this day. The wetbelt system on the other hand is such an engineering disgrace that it is not worthwhile mentioning!
    226
  24. My dad won a 2CV back in 1954 in a contest with Gulf Oil. His jingle was, "fill up with Gulf and you will see, no tailpipe smog or exhaust debris". The theme was emissions. I may have never been if not for that car; he sold it, and used the money to marry mom and honeymoon in Niagara Falls!

  25. The Ford Ts flathead is about the only thing that remains an astoundingly reliable mechanism. It’s true that the side valve arrangement makes an engine immune to valve drop and eliminates damage potential from extreme valve timing issues. Valve drop, by the 70s, was a virtually unheard of issue, but it can happen in OHV engines. The benefit of the flathead, though, is that you can use dirt cheap materials and not worry about it. The multiple-spark system (called SOS in airplanes) helped with the bad gas available at the time, and improved starting with low-grade fuel. It certainly helped with starting especially, but with modern fuel is entirely unnecessary. The T used a planetary transmission, which reduced its likeliness to strip gears, and it’s certainly less likely than even the most modern manual transmissions to strip out and have serious damage. But it was controlled by tightening cotton bands around the ring gears, and these go bad almost constantly. If it weren’t for the cotton bands, the transmission would have remarkable reliability even today. But because of the cotton bands and how they behave, the reliability is very low. The fuel system is drastically improved by the addition of a fuel filter. The bladder device used on the T was sub-par even for its time, and it said in the Ts manual to filter the gas before it was even put in the car. The oil slingers (called “spoons” here) were so woefully inadequate that the addition of an oil pump more than doubled the lifespan of the engine - when oil pumps were introduced they were seen as being the saving grace to reliability. People who lived in mountain states used to fill them so full of oil that they would smoke as if they had blown rings, so much so that bystanders would think that the car was on fire, and this would wind up doing damage all on its own. In some places people associated oil pumps with clean air. The carburetor was finicky and didn’t have an air filter. If dust gets in it’s like grabbing sandpaper for rings. And in many places there’s dust, including on earth. Finagling the carburetor to turn on the car made the car difficult to start. I’ve had experience with crank-start engines that have finicky carbs and they’re an absolute nightmare to get running. The introduction of electric start seems to us as a footnote in history but to the people at the time it might as well have been a gift from god himself. There is the problem of having to back up hills because of the gravity tank, but that’s not a reliability issue it’s just inconvenient. The lack of a water pump is a nice little niche, but that’s because of the low power of the engine vs. its surface area and size. Anything even slightly more substantial needs a water pump. It’s cool that it doesn’t need one, for sure, but no modern engine can do without it, besides something that’s air-cooled. If the Ts engine were designed today (in fact, any engine in any riding lawnmower has made the same HP since the 80s) it wouldn’t have water at all, it would have no water plumbing nor radiator and would just be air cooled. The cooling system on the T is actually quite a lot more complicated than any equivalent engine designed today.

  26. Some VW factory engineers who visited the USA were absolutely amazed how VW mania had added so many performance upgrades to the engine , to the body and to the handling this was expressed in an Automotive Magazine in Germany and inspired a lot of respect towards American VW aficionados

  27. I had a 1926 Ford Model T Coupe in the late 1980's. Yes, the splash lubrication is simpler, but there is a problem. The T was designed in Michigan where it is fairly flat, but I live in San Diego California. I was driving up a long hill with my T, and burned up the rod bearing on the #1 piston. It was not getting enough oil because the oil was mostly in the transmission and back of the engine due to the incline of the hill. In the Model T club, people add an extra quart of oil if they have to go uphill. The brake band in the transmission was just not enough for going down steep hills. In '26 the brake band was made wider to try to help the situation. Due to this, companies made what were called "Rocky Mountain Brakes" that were attached to the rear wheels. An air filter for the carburetor should have been supplied from the factory. In all, I enjoyed driving the car to special events or on special occasions.

  28. I remember a video where a guy sent a DB601 crankshaft into RR to have it measured and checked. The engineer at RR said the specs were spot on to its very high tolerances He said don't drop it because they couldn't make another like it the tolerances were so exact with their modern equipment. Imagine they were doing this in the thousands under constant bombing of their factories.😮

  29. My grandfather told me if a hill was too steep, he'd have to go in reverse up the hill but I forgot why as I was very young when he shared the stry. Now I remember, graviyy fed fuel! If he didn't go in reverse up the hill, putting the tank above the engine, it would stall for lack of fuel to the carb. Thank you for bringing back a memory of my granfdfather.

  30. I had never seen a twin single engine explained before. Nice.
    137
  31. Ground breaking stuff. Mazda is one of the few manufacturers that pioneer new engines.
    136
  32. It would seem easier to me to make the changes at the head end rather than the end that it moving all the time. A 10cc "bolt" that can be screwed into and out of the cylinder is about all the difference required to vary a 6 cyl 3000cc engine from 11:1 compression to 9:1.
    107
  33. The T was made in an era when there was little if any mechanical distinction between cars and farm equipment. It had problems of course, but it's amazing that it was able to run relatively well using such primitive means of lubrication and cooling.
    98
  34. Crazy how ahead of the times the skylines were, all in the times before CAD. This is a good video and needs more views.
    95
  35. I'm impressed. This engine epitomizes elegant design.
    87
  36. I liked the crankcase case compression ratio explanation never thought of that!
    85
  37. Huge thumbs up to them building a working prototype and making a video of the engine running! That already sets them apart from 99% of the other "innovative" engine designs.
    81
  38. Fantastic explanation! Very inspirational to copy the good attributes of this engine. Now I must ask, could you do a engine comparison between 2 somewhat unknown engines? I've never seen them compared even though they perform so similarly while functioning completely differently. Fiat 126p & Trabant 601. You don't have to, obviously :)
    76
  39. The vacuum advance system actually advances the ignition when cruising and the throttle position is nearly closed. The high vacuum in the inlet manifold pulls the diaphragm and advances the ignition as the mixture has leaned out at this throttle position (lean mixture has a slightly longer burn time).
    67
  40. Steam locomotives also used these types of rods, they seemed that they existed for a very long time ago.
    66
  41. I think for a compromise between cost and longevity, the chain would be the choice. I am not an engineer, just just an old guy who has been messing with cars for the last 70 years. Everybody will have a good reason for their choice, though, I am sure.
    63
  42. I've watched four videos on this engine and this is the first one that had any explanation of how it worked, the pros and possible challenges in making it work. I'm definitely subscribing!
    61
  43. I’ve seen a lot of engines from radial to rotary never have I seen something like this 👍
    56
  44. Yes WOBentley used this configuration in the 1930’s on the 8 litre Bentley. Ran like a watch and it came from his apprenticeship experience as a steam engine engineer on the railways.
    53
  45. best in depth dive into the RB26 i've ever seen. Nice job👍

  47. I loved this, and was wondering how they compared to today's cars. Thank you so much for posting.
    50
  48. Thing was and is still pretty brilliant! I wonder with newer technology if this was redesigned with the same basic ideals what it would look like and how it would do. I wonder if it could be sold. Nice video and visualizations!
    48
  49. You did a really great video on the VW air cooled motor but there are so many modern modifications that companies are doing that have improved this little motor . I have a 1979 convertible that’s a 2180 cc putting out around 150 hp and I’m building a supercharged one for another car I’m working on .
    47
  50. Non-stop information, and great visuals and 3d animations. Awesome video, hope to see more like this - thanks!
    47
  51. Yes 2 stroke engines burn oil but our brand new cars burn a whole lot of oil
    46
  52. There was also no oil filter and the bearings were poured babbit. This engine had more in common with briggs and Stratton lawnmower engines

  55. Bevel gear drives were very common before and during WW2 but by the end of the war, pushrods had been made light enough to be competitive even for light racing use. As you rightly say, the eccentric drive does depend on consistent centre distance, however it can be improved by moving the driving gear off to one side and allowing for a little up and down movement in the bottom anchorage for the distance piece. Bentley used an eccentric drive with three eccentrics at 120 degrees which is just about the ideal but expensive. However, the bearings of the rods do wear and are much more expensive than replacing a chain or belt. Steam engine eccentric drives had means to adjust the centres of the straps on larger engines, quite impracticable for the enclosed straps and bearings on a car or bike engine.
    38
  56. Amazing, been driving for 50 years, love cars, lived in the town where Bubble cars were made, but never even heard of this engine type. Thank you I enjoyed every minute.
    36
  57. Waking up to this was an unexpected surprise. I never heard of a hydraulic supercharger and it's counterintuitive to me that higher compression ratios are better for fuel economy. Very interesting and informative. This is my first comprehensive look at the Messerschmitt BF 109 engine after learning about it decades ago.
    36
  58. Just a detail Having worked on 2 stroke diesels both opposed piston and valved the exhaust valves open before the piston uncovers the inlet ports so as to allow the residual pressure in the cylinder to blow down and the valves are shut before the piston has recovered the ports Great vid
    35
  59. Well done. The cooling issues were covered well, didn't know about them until this.
    35
  60. Stellar work! You got a perfect eye for what details to focus on and include while still getting a good & quick flow in the video 😃
    33
  61. Excellent video. The discussion of pro- and con- adds so much to the visuals 😃 Really sets your hard work apart from other creators
    32
  62. In 1906, the Land Speed Record was broken by a Stanley steam car, piloted by Fred Marriott, which achieved 127 mph (204 km/h) at Ormond Beach, Florida.

  63. When Honda revealed the GX series of industrial engines, it almost immediately replaced the old, inline style single cylinder engines in go-karts. It was more compact, ran smoother and fitting much better to the constraints of a go-kart. Basically anything "mini" was powered by a GX or its clone derivative. I dabbled in them for a couple of years, hopping up a clone from 6.5HP to 13 HP. Until the clone crankshaft broke and I threw away basically everything below the head. But the fun thing about these engines is: you can source pretty much any part for them. You dont have to waste money on a clone engine and have a box full of parts you wont use. All you need is a fresh block, side cover, a genuine honda crankshaft, high quality main bearings and the cylinder head. Everything else is pretty much aftermarket hop up kits. And the only investment I highly recommend for your build is a genuine honda crankshaft. Its much much stronger than any cheap clone one. Everything else is basically how much you are willing to spend...

  66. Technical yet very clear. Thanks, I've always wondered why the German V-12 was inverted when no Allied engine maker tried this. Lots of stuff in there I didn't even know I didn't know!
    27
  67. The engine was used on a popular type of very portable fire pump in Denmark by the CF (Civil Protection). It could be carried by two men or equipped with a front wheel moved like a wheelbarrow by one man. It worked!
    25
  68. Trying something new is never wrong. I have to see how this works out, being in a hot and loadsensitive part of the engine.
    25
  69. Thank you I have wondered about this configuration & now I know
    25
  70. Maybe it was just me but the pro vs con ratio was definitely slanted against, I hope decision-making isn't based solely on 20% increase in HP. Sounds like this needs more tweaking before being practical.
    20
  71. Former Ilmor (and Ricardo) engineer here. Those pistons were an Alumimun Beryllium alloy and therefore not harmful at all. Ferrari F1 liked to make up rubbish to harm other teams when they could not work out how to make their engines work properly.

  72. Your channel is severely underrated. I hope you get the support you deserve!

  73. Thank you so much for such a great video! I'm a two stroke freak and I waited so song for this video 😁 Could you make a video about heavy duty engines and its durability? I would be greatful 🥰
    19
  74. Thanks for the awesome 3-D, animated illustrations. It is helpful to see the internal parts working. I've owned a '74 2CV for the past 23 years and drive it almost daily during the summer. It loves our local round-a-bouts and puts smiles on just about everyone it meets. Parts are no problem what with several sources along the US west coast. Love the car. Hills are a challenge but most drivers behind you will be patient while you drive in low gear. We all need to slow down a bit anyway!
    18
  75. Great work. I just discovered your channel and sat through every video you made. I love the descriptions and video content are great for education and make it so measy to understand what's happening. THIS video, explaining the operation of the W engine was above and beyond the best one for making such a vastly complex engineering operation of this motor easy to understand. I look forward to your next and future videos. Your channel is the ONLY channel of my over 400 subscriptions that I hae the notification turned on for. Thanks for the effort you put into these. It shows.
    17
  76. So far, i've never seen someone go into so much details, explaining things in a clear manner. This channel has a great future !
    17
  77. Very clever man, fantastic engineering skills
    16
  78. Thanks for the video. According to a 109 pilot there was a valve to isolate the left or right radiator in case it was hit.
    16
  79. Nice design! But I don't believe the claims without duration testing a full size engine. A lot of wear can be caused by different thermal expansion of the block and the piston. And 30% improvement seems just wishful thinking. But you've made a great video!
    16
  80. this is one great presentation bro, thank you for enlightening us about N2O, such useful enfo
    15
  81. Very nice super clear video with all technicals double checked. Keep it up. 👍👍
    15
  82. Love it how detailed it is.
    15
  83. That Red R33 is gorgeous 😍
    15
  84. Cam is driven by a spring loaded split chevron gear, so as it wears over time the cam timing never changes. Also notice no connecting rod bolts. The con rods are slipped onto the crank at the factory by cooling the crank in liquid nitrogen and heating the con rods. Renewing the engine, you’d purchase a piston/con rod/crank set. All new in minutes!
    15
  85. Great video bro, really informative and well put together keep up the good work
    15
  86. Great Explanation and Visualization , its straight to the point and no frills . I wish more Videos were like this without all the padding and such
    14
  87. 7:57 dont forget that the T was a model that was much more limited in it's evolution. a 1st gen corolla, F series, or Civic has little to do with the current one being sold. the only other real challenger is the Beetle.
    14
  88. I liked your video, so I subbed n belled. My Dad is 92 and healthy. He lives with me. His Dad’s 1st car was a model A. My Dad was 5. The Model A cost Grandpa $35. I just asked him. He’s still talking. Lots of stories!
    14
  89. Another step forward. The internal combustion engine still has a lot of potential. The video is also very well done. Hopefully it will be serialized soon.
    13
  90. In Greece there was a Greek-made Citroen Pony. Same engine and drivetrain but with a jeep-like chassis. Heavier than a 2CV, but could easily fit 10 kids for movie runs! That was with the 602cc engine. I learned how to drive on my dads Pony. It was very fun to drive, especially on dirt roads, thanks to the amazing suspension. It would be interesting to get a video on the gearbox of the 2CV, the weird gear arrangement (reverse and 1st were opposite of each other), why the 2nd gear was the strongest, and why you could go from 3rd to 4th 2 different ways (one was the normal way of going through neutral, and the second was moving to the right first through the location of what would've been a 5th gear if it existed). Thank you for bringing back memories!
    13
  91. Would be great to see any comparison and researches that was done by auto makers regarding this engine back then and maybe we would have a chance to understand why they even did not try it as a POC, or if they made a test piece, which results they got.
    13
  92. I think the humble dry timing belt is the best system even today. If maintenance is performed as prescribed, it will never be an issue. Timing chains can still fail and they are much more labor intensive and expensive to replace.
    13
  93. I LOVE THESE VIDEOS, Cause this is the place to go where you wanna go when you think you know all about engines, but theres more to see, and its type of content know one else gives, showing deisgns and internals and explaining in depth from historical point of view to advantage and disadvantages, to all the components, That is next tier level yt creator. Twingle diesel 2 stroke, and mazda patent mixed with twingle? could be cool. LOVE THIS CHANNEL!
    12
  94. You actually understand the engines you make videos of, not just 'this part made this number and that one made that number' like some other youtube folks. And that's why I like your videos so much!
    12
  95. Actually NSU from the early 50's production motorcycles used this system.
    12
  96. I was a young engineer in Detroit at one of the Big 3 OEMs in the early '70s. I remember following some older engineers into an SAE presentation at COBO Hall where one asked what a foreign manufacturer could teach Detroit? Well, I guess they've learned.
    12
  97. This is the BEST video on the Wankel engine !
    12
  98. Great video, and animation. Ver many years, I've built many of these great engines from 36hp to a mild 1800, and never ceased to be amazed of the clever and simplistic engineering. Properly built, it is bulletproof reliable.
    12
  99. Really nice animations, makes everything quick to understand. What a marvel of engineering!
    12
  100. Great video really explains it all so well.
    11
  101. Great concise and informative video with wonderful graphics... Keep up the good work... I wish all videos were like this... 👍😊

  102. absolutely stellar job on this video sir, great content, great quality, great audio !

  103. The Volvo 5cyl had also an interesting history and lots of evolutions. At the end they where also in the Ford Focus performance models. Excellent video.
    11
  104. This was made in the 90's, the thing is if it was as good as they say it is it would be in use today

  105. TWN = Triumph Werke Nurnberg

  106. I love the idea. It makes good sense. This engine would last. Higher rpms are possible because of greater stability. I hope it's the engine of the future

  114. Hadn't heard hide nor hair of this engine before, but what an interesting take! Like Honda's oval piston design which was meant to mimic the advantages of a V-8 in a GP bike, Wirthwein's engine may not be an advance over the typical piston engine, but it's genius anyway. It also might lead someday to a practical and superior engine to what we have now. Interesting engineer and a well-done video.

  115. My first car was an NSU Prinz 4. I dismanteled it completly and rebuilt it overhauled, those days by a Hanes book (no internet or CD's). The timing was a riddle... quite exhausting and puzzeling. Also, I did resurface the engine head and haven't thought of the timing arms consequences.... it ran (maybe less optimal...)

  116. I've watched another video on this engine, but this, by far, was much more informative, You've gained another subscriber.

  117. Welcome back!

  118. Wow! Something I have never heard of or even thought of myself. I have thought about all kinds of things and then later see them invented and used somewhere so this is pretty neat. When I lived in Germany 1973 just outside of Spangdahlem AFB in a small village our landlord had a small farm and was a mechanic in another town. He had an NSU like in this video, I wonder if that was the same engine. Also interesting, he wore a suit and tie to work (nothing fancy) as a mechanic. I visited him at lunch time once and all the mechanics dressed the same, when they got to work they hung-up their jacket and put a blue or black long work coat on over their white shirt & tie. We ate in the break room, and it was amazing after washing hands they took off the long lab coat and hung them all neatly. I had a great time, they were so friendly and interesting to talk to we even all had one beer with our lunch. The whole shop was very organized and clean. One of the guys who worked there had a 64 SS Impala he bought from an American at the airbase.

  121. You forgot 2 stroke outboard engines for boats (up to and including V-8 engines) and inboard Jet Ski watercraft's. as well as snowmobile and ultra-light aircraft engines. you also did not mention just how many 2 stroke die hard fans there are around the globe. NOTHING can compare to the lightweight horsepower that can be achieved with a highly tuned 2 stroke. and the really odd thing about those highly tuned 2 strokes, is they can also be quite fuel efficient at the same time. Also, those "heavy" rotary valves and reed valve parts that you are describing, weigh in at less than 8 ounces typically if properly designed. the "loop charged" deflector pistons were ridiculous though. they were a very poor design. and limited R.P.M. SIGNIFICANTLY.

  127. Worked for G.T.E wesgo Corp in the 90s. We worked on a prototype ceramic 4cyl engine. Extremely impressive #'s, super lightweight, on cmm machine was No wear....engine would theoretically last forever(well, owners lifetime) it was cast into a block of cement and dumped at sea. No $ in a engine that won't wear out.

  128. WOOOW this engine is an actual wonder in all engine designs, if this get on actual car or motorbike this gotta be a big game changer, considering its supposed wonders

  129. Back in high school I bought a 1958 VW bus with a sliding hardtop for 50 bucks from a friend of mine. It kept popping out the exhaust and bad misfire. Took the engine out and took it to my auto shop and we all split the case and tore it apart and never got it fixed. Now I know I could have snapped those heads off in 20 minutes and put new heads on it. I'm very disappointed in my auto shop teacher but he's probably been dead for 30 years, lol.

  133. The best thing about the model T was that unionized workers in that age could afford to buy one. It was a terrible car, but, as someone else pointed out, better than a horse. My grandmother's father owned one and drove it around Florence, Colorado. They had to fix flat tires regularly, and as someone has said, back up steep hills because of the gravity feed fuel system. If the engine backfired while you were cranking it, it would snap your arm, a common injury in that time. Yes, it was well engineered for its day, but a model T cannot handle modern traffic. It does not have enough power or good enough brakes to drive on a freeway. It pollutes like crazy. In a crash this car would come apart, and with no seatbelts you would lose your teeth or worse on the steering wheel. I would not want a family member driving one. These belong in museums. I've been driving and fixing cars for nearly 50 years and here's what I know: The cars of today are the best in history. Comfortable, reliable, powerful, energy efficient, and safe. Virtually zero maintenance for 150000 miles and many many times safer than a model T or even a car from the 70's. And the electric cars that are arriving now are better yet, wayyyy better. Soon self driving cars will take disabled and older folks safely and conveniently where they need to go. I have several family members who cannot drive so this will be a new time of freedom for them. The model T made car ownership possible for the masses, a wonderful freedom. But let's not get too nostalgic. My next car will run on sunlight and drive itself when I'm too busy or bored to do it. It will be safe, quiet, fast and efficient. I'm looking forward to the future.

  142. Unfortunatly simplicity in today's world just isn't practical. If its complicated, that's today's world. I would DARE someone to come up with something simple. I'm convinced that MOST people would go for the more simple things in life, but most manufactures DON'T KNOW HOW to do simple!!
    6
  143. Its a good idea but no doubt you lose some efficiency driving the super charger (which is more than pumping losses of a conventional 2 stroke). Of course having a smaller capacity engine should help with fuel efficiency so will be interesting to see what fuel efficiency ends up like. As far "Do I think it will delay the arrival of electric cars ?", I think the answer is not significantly as I think that the horse has already bolted (in a lot of countries EV sales already outweigh ICE sales), but maybe it will help Mazda hang in there.

  148. In the 1980's as a young man you would see them boast in magazines about new technology like turbo's and double overhead cams, to name two. Then I found a book from 1920 and every thing they boasted about already existed. That's the power of false advertising.

  150. I had a 69 beetle back in the early 1980s. I was pretty abusive to it as a teenager and finally it dropped a valve. It was a good car. Maybe one day, I will own another one, but I will be gentle this time.

  157. It always made me sad that the RB26 wasn't 3 litres to directly compete with the supra. While I enjoy both platforms, only one has countless JGTC wins, and in Australia.? I saw you mentioned the N54! That's my engine! While you are right about the N54, the biggest perk of this engine is buying a $60 dongle, $60 tuning map and achieving 420ish horsepower with no other mods. If you add better coils, intake and catless downpipes/exhaust, you can get up to 450-480hp. If you add turbos and fuel pump, you can hit 700-800 rwhp.
    5
  158. Yes!!! I’ve waiting so long for another video❤❤ thank you!!!

  159. if you built the lower end of the engine much smaller since there is only 1 rod bearing journal to support and enclose with the engine block your saving a lot of weight from not having a full crankshaft and not having a full engines length of supporting metal on the engine block compared to a typical engine with four rod bearing journals. so honeslty this engine should be quite a bit lighter for its given power output similar to a rotory engine while still functioning mostly the same as a normal reciprocating piston engine. so in an application like aircraft where the weight of the engine might matter more than the absolute power of the engine this might be advantageous. and if a highly developed version of this engine did indeed have identical power to an equivelent engine with a normal crankshaft then this is superior due to lower weight.

  162. In the UK there was an odd, but fairly successful, little car called theTrojan. Very plain, simple and economical it was powered by a four cylinder double, split single of 1500cc. Probably the strangest features of this engine were piston rods designed to bend (a little) and a remotely located carburettor some distance from the engine. No passing oddity, Trojan employed this engine from the early 1920's to the early 50's, latterly in (very slow) light vans and also developed a triple, split single.

  174. Dear Repairman 22 you might like to do a show on the "Rotary Radial" aircraft engine which was widely used in WW-1. It's the only engine I know of where the crankshaft was bolted to the firewall and the engine rotated around around the crankshaft. It was a 2 stroke engine with the propeller bolted to the crankcase. Sooooo... the engine spun at the same speed as the prop. The Rotary Radial was used by the French, British, and German air force.
    4
  175. Not going to mention anything about Snowmobiles using engines that run backwards to shift in to reverse? This has been how Ski-Doo does reverse with a system called RER that has been available since 1998 on some models and on all models since around 2002 or so. You press and hold a button and the engine stops for just a quarter second or so, then kicks backwards. The computer then emits an audible BEEP to let you know you are in reverse. Like a semi backing up. Somehow this does not require an electric start. Not clear on how that works. But since it is a pull start, it can only start in one direction normally and you use the RER to stop the rotation and spin it backwards.

  176. I suspect "low/no need for oil" is the reason. like telling printer companies you can reduce their ink needs by having ink that never runs out and keep the printer usable for longer.

  178. Freevalve has been on the market for a long time, yet its not implemented in any affordable non-sportscar. If youre trying to say Freevalve makes the Poppet Valve obsolete youre wrong. If you say that electric motors make the concept of the internal combustion engine obsolete youre pretty much right, at least for passenger cars
    4
  179. I think Mazda will produce 2 cylinder version for the mass market since the power phase is similar to the 4-pot 4 stroke.
    4
  180. Two strokes power the worlds cargo ships and will for much much longer, altho its not via crankcase scavanging. Marine Diesel Two Stroke engines are the most efficient, reliable and long-living, hence why they are so widely used in shipping

  192. Those old motors, Model T Flathead 4's, were great for the time, but in comparing to a modern 4 cylinder engine, the old T produced no where near the power, they were no where near as efficient, and they did not go 250,00 miles like many modern engines do. Not a fair comparison. Ever sat behind an old flivver and got to enjoy the exhaust smell? Modern engines are truly amazing.

They also had indepentant rear suspension with half shaft axels , combined with rear engine over axel the Beetle was a great vehicle to make into a dune buggy and in 60s and 70s were everywhere.

  200. A very informative video. Thanks for taking the trouble.

  201. It's not about the trajectory of the cylinder, but more about controlled trajectory. In a conventional combustion engine, the only way to control the piston's movement to lock into a vertical one is to make it 's radius keep constant contact with the cylinder, resulting in "parasitic" friction due to the force and movement vectors not being colinear. This engine locks the trajectory of the piston by adding a new "contact" point, thus theoretically making the piston and cylinder friction free, especially on the explosion stroke, although possible that this makes less friction with the cylinder, I assure you it makes a new friction point in the piston pin, so the only way to truly know if any benefits at all cole it to thoroughly test it.
    3
  202. hey, have you seen that engine sound simulation software that your fellow peer AngeTheGreat made? if not, you can program some pretty accurate sounding engines with visuals too. for some of the more obscure engines out there, this could be a great tool for your use case here. it's just kinda tricky to learn the program.
    3
  203. You should mention the VW in competition, i.e., the Formula V, open wheel, single seat road racer, one of the longest running classes in racing history, alongside Formula Ford. VW's were prime targets for modifying as well. I installed a 1600cc Porsche normal engine in one, back in 1966. A year later, I created the 'ultimate VW performer,' when I replaced that pushrod engine with a 1500cc, four-cam engine out of a 550 Spyder. When completed, I tested it to 7000 rpm in fourth gear, without question..., the scariest thing I've ever done on four wheels!
    3
  204. Neat video on a whole, but I have to give massive applause at the end where the number of units sold is compared to the population of the time -- that's rarely done these days, making newer and newer things, be it video game systems, cars, guns, whatever, seem more popular than they really are simply because more people exist to obtain the product -- penetration percentage of the population of the time is often the more accurate metric to go by, as opposed to raw numbers, and this is one of the few times I've ever seen that mentioned in anything talking about overall sales rates of anything between the past and today. Bravo.

  205. The threads for the spark plugs in the cylinder heads where badly constructed, they very often broke and with a huge bang, the spark plug was shot out. I had this and there where ready made kits to repair this, when it happened because it was so frequent. In the first stage, there was a bigger thread cut into the hole and a spiral like thing was put in to hold the spark. When this was also blown out, what often happened, the hole was bored out even bigger and a repair kit was glued in. This was good enough to fix it permanently most times.

  211. Not entirely true. From 1909 thru 13 and 26 & 27, several colors were available. Henry chose to make all cars black because it dried fastest, allowing faster production.

  214. As someone who worked on cars and maintained my own vehicles, I hated that engine. Getting the rear spark plug out was an absolute pain in the neck. Crankcase leaks where a major problem with that engine too. They may have been okay for Europe with their aircooling but in a hot country in Africa they didn't fare too well. My uncle in Namibia told me when he drove his Beetle hard, he often could hear the oil boiling in the sump upon stopping. With that big fan dragging, they were hardly fuel efficient and frikken noisy. I learnt to drive on my dad's Beetle and hated the driving position. As soon as I could afford a car I bought a Renault R8 and it was in all ways a superior car with a superior engine in every way. A dream to work on, the Beetle was a nightmare.

  217. "IN THOSE DAYS" that was fast. It was the fastest thing that Sears sold. The little Sears Compact was actually a close second. The 2 speed Allstate MoPeds were a hoot & used on many, many paper routes. The gas cap was also an inverted cup for measuring 2-stroke oil at fill ups. (A Yamaha FZ-6 IS fast by today's standards)

  218. Great video thanks! Backyard neighbour had one. The sound was terrific

  219. The cam arm moves the crown piston under exhaust and intake - the easiest of the 4 strokes and so the lightest loading .. really interesting idea .. by changing the timing of the “hop” (the cam timing on the crown piston lifter arm) it would be easy to short stroke the intake (create an Atkinson cycle for better fuel economy) .. hoping development pans out !!

  222. No. With a gap of .10 mm there is no way to reach any compression to speak of, and definately not 14 bar. It would just fissel out between the rotors. I used to work with very small tolerances, like .001mm, in hydraulics, and that is what it takes to work with oil under pressure, this is air... Looks fancy in a rendering, but no chance in the real world!

  224. My father bought a new Sears / Puch 250 in 1968 (but it was actually a 1967 model). Looked just like the one in the video. I ‘inherited’ it when I turned 16 (1971). Sold it to a neighbor kid when I got a newer bigger bike. He wrecked it and I talked him into giving it back to me. Frame is long gone but I still have the engine. Great memories! Thanks for sharing this interesting design.

  231. I love to see different engineering. And this is something I have never seen before. I can not say that if I was going to design an engine. That I would use it. I would use either a dry Kevlar belt, or a wet chain. both of them have proven to be quite reliable.

  235. 2:16 The increased ratio of internal surface area to cylinder volume is NOT an advantage for engine cooling or efficiency. Two smaller cylinders will always have more internal surface area than a single, larger-bore cylinder of the same displacement, but the larger surface area needlessly absorbs more of the combustion heat. That reduces thermodynamic efficiency (you want the expanding gases to keep their heat and remain hot) and it creates a larger cooling problem to be addressed by the cooling system. In the case of an air-cooled engine, it would basically necessitate more and/or larger cooling fins on the exterior of the engine.
    2
  236. i was not a fan of bugati. just watching this detailed video deffenetly have respect for thos who made this fastest car!
    2
  237. Triumph made one of this. I still have the engine someplace in the attic. Probably the worst 2-stroke I've seen. The flame front has to propagate very far to reach the other cylinder. The piston of the other cylinder (away from spark plug) got severely destroyed by the detonation.
    2
  238. The Beetle engine had no engine mounts it was supported by the gearbox only.
    2
  239. I drive a model T around almost as a daily. The best way to describe operating one is, "You don't drive around in one, you clamber around in it." There fun to drive,but just be careful around corners.

  242. Doubling the combustion cycle of a 4 stroke and this yields 20% gains? Yeah, that sounds pretty bad. Because it looks to me like 80% of the theoretical gains from adding another power stroke have evaporated into nothing. 100% more combustion which yields only 20% power gains IS TERRIBLE.

  249. Since modern engines run fairly reliably without significant cylinder wear to around 260,000 miles (426000 kilometers) before needing a cylinder bore rebuild, NO auto manufacturer would EVER care about producing such an engine since factory warranties only extend from between 50-100,000 miles (80-161000 kilometers). And NO auto manufacturer is going to want to extend their warranties, period. So, there will never be any interest in such a design by an auto manufacturer.

  260. I think the bearing load is the same, because there isn't a point where more than one cylinder is firing at the time. In normal engine uper bearing takes most of the force, but in this application both would get fairly equal load. That beeing said, I don't think that this engine makes sense in real world motorcycle application.

  261. I am wondering if - since it has many similarities with 4 stroke engines - it would be possible to use such a design and have it switch between 2-stroke and 4-stroke mode. The SkyActive-X engine has a limited rpm band where it can use compression ignition. Perhaps if you can switch between 4-stroke and 2-stroke mode, you can use the 4-stroke mode at low rpm and switch to 2-stroke mode to achieve higher output. This would allow you to use a smaller engine for similar output and hopefully high efficiency at the same time.

  275. You sir are a very talented graphic animator and a great story teller. I watch your videos with joy. I have a request: Could you explain the Brașov D127 Romanian Tractor engine? It has a very interesting background and I have it in my ARO 244 and it's certainly my favourite, but I can only dream of seeing it animated on film and explained all in a video. Or the F8C Daewoo Tico engine. I love your videos, thanks from Romania and I wish you well sir.

  276. Great video Francis ! I'm and old auto mechanic. Have rebuilt 11 motorcycles that I owned. Starting with a Puch 250 that was 2 stroke 2 cylinder engine with a shared combustion chamber ! My Cushman scooter was a 1 cyl. 4 stroke . Hondas BSAs Kawasaki and BMWs followed. This engine exposed here has no crankshaft, or pistons. It cannot be classified as a "stroke" type engine. I believe it is a two cycle rotary engine. It has an intake and exhaust cycle that produce power in a cycle blending combustion part of the engine rotation. That could be referred to as a third cycle; making it a 3 cycle engine !! I think it would make for a great multi fuel electric hybrid engine, that drove a generator to alternatively power a BEV. Its light weight and high rpm. would provide great flexibility to powering a vehicle.

  279. That was a great little engine but you are not mentioning a major weakness that has been kept secret...the oil cooler vented just ahead of the #3 cylinder which caused the #3 exhaust valve to overheat and drop its head into the cylinder doing a lot of damage. The 1966 Squareback sedan had the same defect which was corrected in 1968. I know because I rebuilt a 1965 Bug and a 1966 Squareback engine that had this failure.

  300. Come on! Is this a prank? Obviously piston wouldn't return during intake stroke hahahaha So how they tested this on fiesta and some diesel truck hahaha This "invention" is clickbait nonsense, it has not real advantage. Even if it were functional, ball bearings and belts wear fast, engine would have horrible sound because of knocking sleeve to cylinder and vibrations would cause more stress to the engine. So it would make less horsepower for less durability, heavier engine and using more space that could be used for e. g. turbo or supercharger.

  328. You can add to your very good analysis that when having a little leak on a rocker covers on the vw , it would drip on the exhaust bringing smell and fumes inside the cabin , where on the 2cv exhaust is by the top driving to a clean heating system. The vw rocker cover cork gasket gets easily sucked in leeding in a major leak if not changing the kork gasket at evry oil change , why , because there is nothing holding the gasket in position. Even torked to its 300 newton meter value the flywheel single center main bolt would come undone if not using locking thread compound. When the thermostat would fail , it would close the shaters leeding to overheating , to avoid this , remove the thermostat and block the shaters permanently in open position. Also , do not use ngk plugs because they do not hold well temperature , use Bosh or Champion spark plugs because an air cooled engine can reach up to 250°c température and cheap plugs will put you in trouble. On vw air cooled , noisy tapets needs to be often adjusted where on 2cv this problem do not occur. Vw 1300 air cooled goes ok . 1500 engine is also quiet ok. 1700 engine overheat going up the hill. 2000 engine is a desaster in overheating. I worked for a specialised garage in vw air cooled in uk. Panhard air cooled and Citroën air cooled , what a class.

  370. Toyota Corolla has 21.5lbs per hp. Ford Model T has 60lbs per hp. Toyota Corolla makes 77.2hp per liter. Ford Model T makes 6.9hp per liter. Now the highest end Corolla GR has a 1.6L three cylinder motor with 300hp and 273lb ft of torque. That would make it 10.8lbs per hp (it weighs 3250lbs) and 187.5hp per liter. 13mpg sounds like it's not bad for the Model T but these numbers don't lie. It was incredibly inefficient at making power, so you're using 13mpg to make barely any power out of a big motor. It was great for the time but motors exploded and died for a long time before they got truly reliable. There's a reason old cars only had 4 or 5 digit odometers because 100k+ miles on an original motor was unheard of. Sure they were simple. That didn't make them reliable. That was just the tech they had at the time.

  379. There were tuning kits with displacement up to 700ccm... I had one, measured 39 hp on the mechanical school's dyno... Same as the VW Polo of a class mate, who wasn't happy about that 🤣 This thing drove over 140 km/h (87 mph) with the differential from a Dyane gearbox, overtaking Smarts, that were limited to 135... It was a fun! Fuel consumption was less fun... 8.5 up to 10.5 l/100km. But fuel was cheap in the 90s. I still have the car and the engine... But swapped the engine for the 650ccm from the Citroen Visa. Almost as fast, electronic ignition, and I was able to legalize it at the TÜV.

  383. Suck, squeeze, bang, blow. That's a 4 stroke in 720 degrees of crank rotation. It doesn't matter that the piston and cylinder only make one horizontal revolution, the crank is going around vertically 2 complete times, 720 degrees, to complete each cycle. I would think that what limits rotary valves would also limit this engine, seals and lubrication for the ports. Still, a novel and interesting design.

  417. Nice video!!
    1
  418. A very well done video. However, I have to disagree with you on one thing and that is the camshaft drive. The large gear was made of some kind of compsite material that did not last very long. In my young mechanic years I replaced dozens of them. Later they changed to aluminium and that solved the problem. They also had a problem with the cooling of #3 cylinder for many years
    1
  419. Too much complexity. No benefit. Might as well just have 1 gear driven camshaft and pushrods. The possibility of valve float can still exist since there is a overhead cam. Interesting although. Great video

  420. Hi, Repairman22, Thanks for your discussion on the split piston ICE. The main idea for it is the huge differences between the gas pumping exhaust and intake strokes and the heavy compression and power strokes for the ICEs. If we split these two functions the engine can run at 1/2 of the rpm for the same work otherwise it will produce 2x (actually 2.5 to 3 times torque). So the crawn section can be redesigned to run at somewhat higher speed with lighter system, since it just pump gases around. Basically, this design make an different hybrid of different kind. Other issues such as: 1. windows in the skirt is not away needed or just a litter cut is enough. 2. the cooling is much easier when stronger and thinner crown is used. 3.there is no oil leak issue if the piston rings are OK, 5. the "extra moving parts basically is the extra cylinder, i.e. i4 becomes v8 (or 2.5 to 3 time output), 6. The engines would run at half rpm, not the 1000rpm, 11. the push-down spring has the help by the the cylinder press at high rpm when the engine is loaded. The crown (piston-train) has about just a little high speed or the same depending upon what differential strokes are designed. The crown section is only to pump the gases around, which much, much lighter than the pushing the whole vehicle around.

  426. My first car was a 56 vw in 1966 I paid $100 for. You could remove one cylinder, piston and connecting rod without removing and disassembly of the engine. It had a sunroof and by pulling out the choke a bit you could drive it standing on the seat and halfway out the top. (College days). You can't beat it in the winter in deep snow with chains and being flat underneath you slid over deep snow drifts. The heater didnt wok so I tore all the guts out of the heater boxes and closed the little doors with sticks in the fall and all the air that cooled the motor was blown into the car. I had to drive with my windows down on a trip. If you got stuck you could speed up the engine a bit with the choke and get out and push with it in first gear. Driving through the Rocky Mountains in British Columbia was like rowing a boat with all the shifting. I cut 2/3 off the shifter to make it easier. I loved that car.

  427. The engine was also used as a pump for fire fighters.

  432. After going to the so-called 'manufacturer's' website... it appears to be an engine that can sorta run for 8 seconds. I see a failed kickstarter coming. And it only runs on hydrogen. There is no possible way something like this can run on a conventional fuel and be useful in any application. I would expect it to produce close to zero torque. I appreciate your animations... but it is unlikely to go beyond that.

  434. A whole lot of people in this comment section couldn't even watch an 8 minute video in it’s entirety before posting their comments, pointing out that detroit diesels exist doesn't make you seem smart, it only shows you didn't pay attention to the video

  435. Bali island. You can tour the island by renting a VW beetle with open top + driver/guide. Better view when there's no roof. There's an unwritten law, that VW owner can't sell his car outside Bali.

  437. I can remember that this engine is nearly indestructible. Both my mom and my dad had a 2CV and they made road trips all around europe and when the car was done from rust, the engine lived on and as far as i know, it runs to this day.

  439. It’s an interesting engine, but like lots of French engines and cars , seems to lack any consideration when it comes to maintenance or repair. It’s like they though ‘how can this be made as hard maintain as possible?’ The points for the ignition timing are behind the flywheel. Completely inaccessible. Good location? Not. I hate French cars, everything seems to be designed to be in the worst possible place, nuts and bolts go in backwards, and hit the chassis, but if they went in the other way they would come out easily. It’s not accidental, it is deliberate. They want to make the repair times as long as possible, so they can charge 5 hours for a job that could be done in 1 if they just used bolts instead of studs, or studs instead of bolts, etc.

  446. ​ @repairman22 glad to hear there are still real people narrating, the amount of videos with no human voice are quite worrying from the point of view that we, as people, should still be willing and able, more capable of making a good, well read, pertinently expressed narration, with touches and nuances that AI has yet to accomplish. I think, w.r.t. the 4 stroke comment, I was, as some people might, considering each of the 4 stages of the cycle as a crankshaft revolution, rather than happening in a downstroke or upstroke of the piston. Thanks so much for pointing that out! I have watched several of your other videos too, like Ford Model T, VW Beetle engine, 2CV engine, Titanic, I think it was, a fire engine truck, et al, and your work is a joy to consider, and helps one understand so much more than was once possible when I was a youngster, and graphics were mostly static pictures, with slight descriptions. Best wishes!

  454. That's the trouble with our world the and the unimaginative and stupid are in charge. Yes the mechanism by which you would boar the cylinders would have to be slightly different than what they use on conventional engines. But come on guys do really think present mass-produced engines are not made on specially-designed production machines.

  463. My scooter and my outboard are two-stroke engines. Never had any issue with them. Yes, they smoke and stink but as far as reliability goes they can't be beat! That's important for me as an engine failure on the land ain't a big deal but a failure on the water will cause you big trouble from 1. second on. Exhaust tuning is a science in itself. I remember doing countless tests as a boy on my 50 CC moped until I found the sweet spot. :) Thank you for this video it's great. :)

  464. The 3D animations are out of this world. Gargantuan amount of information here. Now, not to be nitpicking, but you saying that "central timing" is what is used nowadays sounds incorrect. Maybe my english isn't good enough. If you're talking about where the timing chain/gears are, those have been - on in-line 4 liquid cooled engine - located on the left side, not on the center, for many decades. Since in-line 4 liquid cooled engine is by and large the most common internal combustion configuration, both for cars and bikes, it seems to me you're talking about air cooled engines from the 70's. As for your mention about Yamaha's engine, I'll first need to check into the shop manual downstairs.

  465. Thanks!

  466. That's pretty nuts how the engine basically had a gun in the center of it... lol

  467. More points to add...the cam drive gear is split in two halves ( like putting the palms of ones hands together ) they are spring loaded in opposite directions to compensate for teeth wear which would otherwise affect timing. Another curiosity is there are "no" rubber flex hoses in the hydraulic brake system only steel piping! The large hollow cross chassis mounted tube supporting the rear trailing arms (via ball bearings) also houses a coiled hydraulic pipe internally. this steel pipe runs down each trailing arm to the wheel brake cyl. Since vertical wheel movement is limited the internal coiled pipe accepts this without stress. Front brakes are inboard either side of the chassis mounted differential/gearbox so again the piping is coiled (less so) to compensate for vibration or engine movement on its mounts. These cars are technical wonders in many ways.

  480. Different compression ratios are amazing. I think the same, and even more strong, problem should be at Subaru engines. Amount of oil going to left and right sides must be very different. I think that is a reason of the 4th cylinder knocking, just lack of lubrication and piston cooling.

  484. Cool idea, biggest problem will be a big enough supercharger. Would require basically a bigger air pump than the motor. My 800hp 6L uses a 2.3 liter supercharger & it's huge.

  485. Meh, Mazda's external compressor solution is better, and can be retrofit to existing engines.

  486. It isn't double the reciprocating mass, it's roughly the same reciprocating mass cut into two pieces, & it's not only a drawing; they literally showed running prototype engines in the video. It is double the moving parts though, and those valve ports are never gonna seal right.

  522. It's an obvious fallacy to state that lacking parts such as an oil or water pump increases reliability. Yes there are fewer parts overall, but those additional parts contribute greatly to the longevity of the entire engjne. How many Model T engines would last 200,000 miles or more without a major rebuild, something that is absolutely unexceptional today? Comparing the fuel mileage of the Model T with the "average" fuel milage of modern vehicles is disingenuous at best, and bordering on dishonest. A small gas engined car today will get at least double the mileage whilst making maybe four or five times the power of the Model T from half the displacement or less. This is not to take anything away from the Model T, it was a huge success for good reason and a credit to Henry Ford. It is mechanically very simple and much easier to repair than modern vehicles, but those repairs were frequently needed.

  527. Sorry. Despite the great engineering it had one huge shortfall in snowy climates: NO HEAT! no heat for the passengers, and critically, no heat to defrost the windshield! I have a vivid memory of driving in my high school friends Beetle in a snow storm in CT with both of us with our heads out the window trying to see the road at night. It should have been criminal. Ralph Nader missed this one.

  528. I learned to drive in dad's '66 Beetle. No radio, 6 volt electrical system, dangerously dim headlights, etc. As basic as a car can be. When I'd get stuck in the snow, I'd put it in 1st gear, hop out and push myself out. Rust put an end of that poor car when it was 10 years old!
