Yeah I don't get this. At first I was like cool. They have more energy for their batteries. Motors are amazing, and they should. The teams will find the best ways to get more from the motors now. Then they start putting limits on everything about the system while using less powerful fuel... The sport seems to be losing its identity. It needs less rules. More unique designs. Cap the money somehow if that means only richer teams will win.

This looks to me like a cash grab. They are being sluggish on purpose with their EVs with this. There is nothing inherently that bad anymore about electric vehicles accept infrastructure. Yet when I see old manufacturers designing things like this I question why. Why so gimmicky. We've had a century of learning how to place functional buttons and handles. They aren't changing for the better. All these things seem software related. Hopefully VW can make those changes in an update. I also understand that a lot of the world doesn't need non stop 4 hour driving on a highway. So the 185 range isn't a deal breaker. Yet it is 2025. It should have better performance or a much much lower price. This is ridiculous. You buy electric for performance from what an electric motor provides. 325hp, 185mph estimated highway at 70k? What a joke at that price. Thing should be able to do 4 second 0-60mph. Or have 500 miles. Something. Germans should be ashamed like I am ashamed with Ford, and people should be ashamed of Toyota. They half ass their electric car designs, over price what you get, and cry when the public doesn't buy them. Having China beat us is unacceptable, and that is exactly what is happening. Just remember the electric motor is superior in performance. We can build much better ones. Do not buy this junk.

That is why I like you. A lot of car guys are ummm... Low brow. They are biased, and many make up nonsense about EVs or use some outdated information from a decade ago. EVs are great. Loads of Teslas on the road with 150k miles and 90‰ charge. The newer battery chemistries are said to be able to keep charge for even a million miles. The thing about that though is the manufacturer will never allow that. Even if the batteries last other parts will fail.

The progress in batteries is crazy these past ten years. First twenty years of my life batteries weren't that crazy from each other. Then bam! Cell phones and then EVs sped up investments. CATL just said they have a battery with 10 years warranty at 600k miles. Supposedly has similar if not better density. If any degradation happens they'll replace it. That is a million kilometers with little maintenance. I've also read research saying a lot of batteries cap at 90% for newer batteries. Yet I myself wonder what charging method is used. I think any videos like this should focus on newer batteries, but from what I gather since we don't have info it is hard to judge some of the newer chemistries. Can't wait for certain battery techs to leave the lab. Even if you don't care for EVs battery tech is super important for a lot these days.

Honestly you're worried about fringe cases. If the triple redundacy is messed up that bad that vehicle is most likely totalled. I mean the thing is built solid, and high off the ground. Person would have to run over a 2 foot rock or an other car. Like what do you do when the steering rack and pinion doesn't work on a regular car? If it works for planes. It will work for vehicles, and will be the future for sure.

I like the change. Jason is honestly charismatic. His ability to give out perfect data while talking without slipping WHILE driving is insane. This video just shows how important having an editor is. Takes Jasons charisma, and turns it up a notch.

I heard newer batteries are capping out at 90%. Also I've read we really don't have a lot of data on newer chemistries which makes sense. Yet the predictions are pretty good to me. CATL has a battery they say that will last ten years for 600k miles or a million kilometers. With modern power densities. If true that is crazy. Batteries aren't going to be the weak link eventually especially if solid state takes off. I hope. That is if you beleive what all the companies are saying. Lemme tell you I love how fast battery development is during my life. It seemed stagnant then boom the past ten years have been crazy. Even if you don't care about EVs the progress in batteries is a damn good thing which opens up so many things. Just waiting for lithium air chemistries to have a break through damn it. Being able to get the oxygen from the air looks amazing as far as theoretical power density goes. Something like 12,000 watts per KG at max therotical density. Even reaching half that would be game changing. WE could finally have exoskeletons!

@VoidSinister I've got a lifted F350 Tremor dualie. I will crush your little toys that you call cars. Maybe I've already have, and thought it was a pothole that screamed. Just playing. That was an odd comment he said.

Lucid needs a better marketing team. Seriously their cars are better from what others are saying, but they aren't even on some radars. Get some eccentric engineer who becomes the face of the company who calls Musk to a WWE or MMA match! Jokes aside what they also need is a slick futuristic car. Sort of disappointed with the look for their SUV, and I was ecstatic they were coming out with a new vehicle. A lightweight sports crossover like the EV6 GT would be sick. Make that thing look futuristic even if it costs some range. What I am trying to get at is they need to stand out. Make excitement for their vehicles, because the product for all intents and purpose the best EVs. One reason I will never buy a Tesla? Is the fact their interiors have no buttons, and are so bland inside. It was cool back in 2014, but not now. I also like the tactile feeling that buttons offer while being faster than going through touch menus.

I don't always understood the white board. I do however understand 60 to 0 in 87 feet, which is LESS than ten yards! I understand that is crazy. 75 to zero should be the one they test though.

@Technosplosion What is the point of a hydrogen vehicle that an EV can't do? Batteries are only getting better, using less of the rarer resources, charge faster, and hold more charge! Tons of break through have already happened in the labs. They just need to be brought up to scale or get manufacturing worked out. That doesn't include the other benefits of EVs over hydrogen which is acceleration. Then you have motors which are also getting significantly better like Koenigseggs Dark Matter which is just one of the most ridiculous motors out there.

@chriskelvin248 diesel is half as efficient with less power and fuel is getting expensive. Just saying it isn't a 1/1 comparison. Give batteries five years. We will get there. Just not yet. Need to design motors for hauling as well.

@jeffpicken5057 I don't mind a giant screen. I however hate the lack of tactile buttons in Tesla. Going through a touch screen for simple things is annoying. Rolling down windows and locking doors is annoying to me. Having knobs, buttons, and switches honestly is easier after I get use to it and it looks way better when done well (that is my opinion though.). I mean it is better than touch pads though!

@ColtonRDean Yeah. Hydrogen for planes and ships EV. NOT FOR CARS. Hydrogen for rigid airships! Not. For. Cars. Hydrogen combustion engines is just a ridiculous idea. As batteries and super capacitators continue to develop as fast as they have? No reason for hydrogen at all. Doesn't make a lick of sense from any point of view outside space maybe. I guess having a sub or underwater structure that could essentially create its own fuel would be cool. Not that I'm against nuclear.

He is pretty unbiased for a car enthusiast. Most hate EVs for all sorts of reasons, and will jump on any flaw while completely ignoring the advantages. Like talking about range always like charging at home for pennies on the dollar isn't convienent. They all act like they have to drive more than four hours a day without breaks. I think EVs are good now for 70% of the population, and will only get better. Solid state batteries are coming out which I hear are not only better in energy density, and for longetivity. Me? I like them due to superior practical speed, balanced low center of gravity, and the fact they are silent.

@TheMagache How is switching to EV about more control? Or better yet how is it any different then gas? You got an oil rig or something in your backyard hidden from the government or something? So when the government tries to control us. You can still power your home or use your car by just drilling? A Saudi friend willing to bring you a few tanks monthly so you can fill up on the cheap? Nah. You go to a gas station. One that you don't own, or have any control of. If anything an electric car allows you to live OFF the grid. Tons of people are already doing it. They have solar and wind power, plus a storage system. Which allows them to power everything electric they have. From home, tools, and CARS. Some of you people don't even think about what you are saying. Like come on. Solar/wind+ Battery + EV = off grid. They are also the cheapest form of energy generation now.

He like many Americans uses both. Which is annoying. Especially when talking to aviators and mariners who are American. Going only about 20 knots with wind to the stern with a 2 liter of coke and only a few gallons in my gas tank. The weather was about 100f in the sun but the wind was blowing at about 10 mph. Then got home which is about 20 miles and had to pick up a gallon of milk and an ounce of weed. Made it just in time to see Brady throw an other 90 yard pass too! Went to bed at o'22. - Some American in the Navy. Quite honestly you have to learn both. I wish we would convert except for Celsius. 0 is cold and 100 is hot. 50 is just right. Thought the British also use imperial at times no?

@hashgeek929 I was joking, but looking back it was a poor joke for text. Ya know meaning I don't understand the white board or anything for that matter. Cheers!

That is the benefit of manufacturing without having to use the same tools I think. They have the engineers that can do it. Just then it has to flow through marketing and manufacturing as well before getting the stamp. Hopefully they stay relevant though. I personally don't like the looks of their front, but I get it. They aim for pure efficiency at the cost of looks. I would give up it even though that means giving up on range.

@SGTGGeorge Battery EVs are already just as good as any fuel cell, because we cannot find a way to tackle hydrogens volumetric density issues. The Mirai is heavier than a Model 3, and has less space due to the storage tanks. Very similar ranges if made today with newer technologies. I just don't see anyway past this problem. Especially when there are batteries being produced today with 500 w/kg! To put it into perspective the best Tesla has is less than 296. Many think closer to 260 or even 240. Those 500 w/kg are made by Amprius who is trying to scale up fast. Chinese companies say they have made 500 to 711w/kg batteries. Hydrogens time for being a great energy carrier is just gone outside of niche applications. Even after the volumetric density issue there are others like high cost of a catalyst. Cost of actually producing hydrogen. Zero infrastructure. Troubles storing it. Dangers of leaks. I wish I was wrong, but I'd bet I am right unless some storage medium break through happens.

@krazytroutcatcher Some of you are partying like it is 1999 still, or some of you think that Smart Phones are new technology, hah. EVs are here if you haven't noticed. The thing about batteries? They are getting cheaper, safer, charge faster, getting lighter, and holding more power. Then compared to fuel cells they will give more power, and have lower volumetric density then hydrogen. Oh EVs are safer in crashes, and so much more reliable than the ICE. Less maintence too. Sure they burn worse, but they also catch fire less. Burning is burning. ICE is dead in the water. You'll need more and more complicated crap to get any miniscule improvement. We have solid state batteries coming out which are a leap toward. Then lithium Air chemistry is the future, and will have the potential to be ten to fifty times better than current batteries as I write this. Oh with pure EVs? If you had the money you can charge off the grid at your home. No need to worry about gas stations running out of gas every time some disaster might happen. Or gas prices going up daily. There are people with solar trailers who will go camping, hunting, and fishing and charge their vehicle in the sun while they fish all day. Also if you guys think mining and battery companies are somehow more evil then oil and hydrogen companies? Well you're smoking some of that good stuff, because they are ALL greedy and ALL want all of your money. By the way lithium is everywhere. Mining it is also getting easier and less of a hazard. There are companies working on extracting it from sea water. But hey don't buy an EV. Personally I like them because they blow ICE out of the water. I dont need to drive 10 hours straight daily without breaks like apparently you guys do. Will be blowing by you guys in your ICE soon.

Yeah Jason's smile when he was racing says it all. I love EVs purely due to performance, and could give a damn about noises or such. Yet watching him smile while driving is contagious. I'm all for it. Also you don't need to use it all too.

@WarpedYT Dont know what engine that guy is talking about but I do know Honey Well was in the running for US Helicopters like the Defiant X. Thought the Valor too but Roll Royce took that. So it wouldn't surprise me thst they make super high RPM engines. Yet I only know of turbines.

Oh I forgot to mention it. Guess where we get half our nitrogen from for fertilizer from? Fossil fuel production! So it either requires mining, and all the green house gases that entails. Or more likely requires fertilizer produced by fossil fuel production! You can't grow corn on just water, sunshine, and love. We don't live in a Disney movie, where you can sing to crop for it to grow big and strong. Give it hugs and kisses. Put a knob up yer arse, ya sick fucks. Algae and Phytoplankton are the best options. They can produce anywhere from 10-300 times more oil per acre depending on what crop you're comparing it too. I don't remember which one is better. You need sugar or fat to produce biofuel. What an acre of either looks like is beyond me. As all the places I've seen had vertical tunes. Also off topic. While algae is amazingfor nutrition and calories. Phytoplankton is just insane when it comes to how much nutrition you get per gram. Seriously I would die if I ate just a spoon full of it a day, due to how much nutrition and minerals it packs. I have kidney failure (hepatorenal syndrome). No wonder why Whales get so big eating the stuff. Crammed with micro and macro nutrients! Oh snap. Last night I also learned that they've found bones of a whale that is said to be 85 go 345 metric tons compared to a blue whales max 190! More bones are needed, but it may very well be the largest animal to ever exist.

Yeah it is an artifical market just as bad as the oil companies themselves. Going green? Hell no. Better for your car? Nope! The irony is the farmers are so hypocritical. Mostly Republican getting subsidize left and right for an artifical, and forced, market that is just accomplishing nothing except forcing us to grow corn when the land could be used for something better. Big lobby and farmers got us.

He was over 50 when he released this video haha. Just playing but he jokes about it all the time. Thought he was older.

Minimal cost? You act like you can put hydrogen in your gas tank, hah. High pressure tanks of 700 BARS plus are expensive, bulky, can't be formed into different shapes, and still carry something like 22 liters... Then you have the cost of infrastucture. Yeah have fun going from power plant, hydrogen plant, shipping hydrogen to station, vehicle going to station, then using hydrogen. Instead of just power plant to vehicle. Hell people can use their own solar or wind to power their cars. People already have solar trailers towed by their trucks to power their vehicles while camping. Can hook up power tools to them too or use them as a generator with some of the new EV trucks. Then you have the electrical strain on the grid which will be MUCH worse. Hydrogen takes a ton of electricity at the moment to separate it from water. If people think billions of EVs will be a problem on the grid. Then Hydrogen will be double the strain at least! Batteries are rapidly progressing. Hydrogen is stuck by physical limitations by physics. There will never be a solution to hydrogens volumetric density problems, and fuel cells will never be as efficient as batteries to motors. Companies have recently made lithium air batteries. Those will be ten to fifty times better then the batteries we have today. Solid state batteries are coming out this year. Batteries will become quicker to charge, be more power dense, lighter, and safer. There is no real infrastructure for hydrogen, and there will probably never will be. It will be a niche product. Which sucks. I wanted hydrogen to succeed. Until I learned the physical limitations, and theoretical limits. I still cross my fingers for some science break through with space age magic nano tech. Fun fact about hydrogen. Water holds more hydrogen in a given volume by a ton compared to just pure liquid hydrogen! Doesn't make sense.

Wire is safer, requires less materials, and easier to design a car with it. Fly by wire in planes has been around for YEARS. Believe it or not electronics when made to be durable can be more durable and last longer. Not to mention you can have all the redundancy in the system you desire. Once we get some clever haptic feedback systems in place? It will be the superior option just from a material standpoint. We already have sensors in and around the wheels.
1
This is nothing more than a gimmick for gas industry companies to say they are trying to combat green house Gases to me. Maybe get subsidizes and tax write offs. It is a mockery of effiency. The fact green hydrogen isn't close to being cost effective, dangers of storing it, and most of all volumetric density is down right terrible.

Well if people are correct and the issue is how corssosive it is, and what it does to other parts that then impact the engine... Then a long term test is required to show that. Then to find out what to do about it ideally. This test is like me taking heroin for 3 days then being like. "Yup. As long as you don't OD. It is totally safe for you." And that is actually true. Taking heroin for 3 days won't really do anything. It is the life style choices, and lack of health mangement once you get addicted that makes it so bad. In fact I need a liver and kidney transplant, and many organs come from opiate addicts since it doesn't really hurt many of their organs. (Short of STDs, hah. Wait that isn't funny.) I would just like more data.

@Ericwvb2 Fun fact! Most fatties on average only over consume an average of a large regular soda! So ordering a diet coke after a ton of other things is an actual recommended strategy. I don't even think it is even per meal but 200 calories which can be one giant soda from a store. I was told that by my dietician while talking about how people get so fat. An observation I can't prove. Diet Coke drinkers specifically are the coke heads of the soda world! It can visibly ruin their meal or day if they don't have it. Start prowling the town for a diet coke fountain then in desperation buying a diet Pepsi in disgust. Also Mexico blames America for them drinking 4 liters of soda, because they don't have water treatment plants for their own general use! So silly for governments to expect a buisness to do their job.
1
Yeah that's what I would be aiming for. I don't like eating and driving either so stopping on a long distance journey for a cigarette and bathroom break is a must. Worse comes to worse stop to stretch legs and eat some gas station snacks or pizza or something. You'd think those huge trucking stops would have super chargers now right? Like the bigger stops should have chargers I would assume. So I'm wondering how viable it is. Yet the bigger stops might have more people waiting for the chargers... So what happens then! Hopefully people don't go and take their sweet ass time blocking the charger while they stuff their face.

Feel like a standard generator would just be as good ya know?

@MixingGBP Oh for sure. Yeah I just think it is the cost of the power wall that is what really caught me off guard. I had no idea such systems were so expensive and the math seemingly checks out which is just... Crazy. Even if it isn't perfect you still have from what I hear a freaken decent truck that you can use to sell later. Can't really say the same of a power wall! Maybe liquid batteries will become a thing. I know large scale projects are popping up and they seem promising from the required materials to storage capacity - anytime weight isn't an issue like for a home basically. Not sure if people would feel comfortable with super heated materials being around their home though but most are aiming for making them with basically harmless materials where clean up is an issue but won't contaminant your property.

@jkliao6486 I use more than two mate depending on who I am talking with. Then when it comes to aeronautical or ship we use nautical miles and such.

It would not suprise me if he talks math and car specs in his sleep. It is insane how good he is and just remembering, and communicating it. He will be driving down the street without even stuttering.

That truly sounds like something an engineer would do without worrying about the poor mechanics and machinists who have to deal with it. Truly that man is living his life, and making his dream come true. I may not be religious, but God bless him.
