They would need to make this track much wider or all the F1 cars are going to drive on the same line meaning no overtakes.

@MultiArrie I'm pretty sure you can create tracks that have fastest single car wide racing line with side effects. For example, the fastest racing line could cause heavy tire wear whereas e.g. going slightly higher on the ramp could be slightly slower but reduce tire wear a lot. In such case, over a long race you cannot always go for the fastest option which would help with overtaking.

@1crazypj Nobody wants straight cut gears in normal road cars due the noise. And for only 4-6 gears creating a non-sequential gearbox saves about 4-6 gears. If sequential gearbox was actually cheaper to make, VW and Toyota sure have resources to make those boxes in mass production instead of their non-sequential stuff. When I wrote "hugely expensive" I meant the current situation. "More expensive" would explain the reason why those are not mass produced for road cars. I would estimate that sequential gearbox would be 150-200% of the cost of non-sequential gearbox for road cars if it was mass produced.

I'd argue that you can go way past 21000 RPM if you truly want but you wouldn't get more power per engine cc because of compromises you would have to do for a gasoline engine. However, if you run nitromethane such as RC cars, you could easily run engine up to 50000 RPM. Of course, at those RPMs you would get better economy with a helicopter style gas turbine engine if you have enough money to get one of those. ...and your racing regulations allow you to uses non-internal combustion engine.

Congrats on your wedding but unfortunately I cannot help with subscriber count because I've been a subscriber for a long time already.

I would say it was seat of the pants traction control system. I think it disturbed the balance of the whole car and he used it to check both the traction of the rear wheels and the front wheels. That said, I think it caused more wear to tires and as those are intentionally inferior today, this technique wouldn't be good for F1 driving where taking care of the tires is nearly the most important thing in fast racing.

I think the next season of "Drive to survive" must start with "based on a true story" or viewers will say the story is not believable.

@_F_rog If they can do 700 meter long steel structure with safety critical parts for only a couple of million, that's cheap!

@bideomanlol The F1 cars use collapsing tanks to avoid fuel sloshing around in the corners inside the tank. Could ethanol vapors cause enough pressure to prevent the tank from collapsing when fuel gets low? If the fuel sloshes around in the corners, the fule could easily be cut from the engine given the high sideways g forces that F1 cars can generate.

@jean-jacqueslavigne3109 methanol is not allowed in F1.

@jean-jacqueslavigne3109 Maybe that's April fool's joke? I cannot find anything else about F1 and "binex".

For road cars, the spring where the coil has different strength for diffent parts (usually implemented with non-equal rise per turn) is usually called progressive springs in marketing material. It's much better than regular spring but more expensive to manufacture.

Kalle Rovanperä did something similar in Porsche Benelux series a couple of weeks ago. Kalle has two WRC Rally1 championships so he can obviously drive cars fast but Porsche Benelux series is about every driver having identical car and very minimal adjustments allowed and no ABS, TC or stability control to aid the driver. And still Kalle was able to win 4th race he attended and he set the P1 in qualification for 3rd and 4th race. And you have to remember that this 24 year old driver had rally experience which requires very different driving technique compared to circuit racing.

@Hole_Motorsports If you look at the video around 7:30 mark you'll notice that there was already a catch fence. The question is, what if the tire (separated from the wheel!) bounces and goes above the catch fence?
1
@tomasgamboa3164 Yes, I'm giving an option how I think the rules should be laid out to allow fair racing. Why do you think you have any authority to say who can speak and who cannot?
1
@tomasgamboa3164 It seems to me that you're jumping to conclusions pretty fast. Perhaps there's some kind of language barrier between us? English is not my native language so it's totally possible that I explained the situation poorly. To give a concrete example, let's take 90 degree turn to left. Cars A and B are running side by side before the corner, A on the left. My point is that if you allow A to run up to 2 tires over the outside track limit (the usual limit for track racing as far as I know), there's no way for B to overtake A. This is because A can always start to brake so that he or she could be take the line next to apex preventing overtake via inside. However, during the braking A can see how B is behaving. If B brakes hard, A does so, too, and can position his or her car next to B preventing overtake. On the other hand, if B tries to overtake by going outside, A just releases the brakes somewhat and runs up to outside track limit with B alongside which forces B to basically stop or run out of track limits. Do you understand the case I'm talking about? Do you think B can overtake at all if A behaves like I explained?

@nearlyretired7005 Adding points to license for every time you go outside the track limits might be a good solution. Obviously, if you DNF there's no need to give out penalty points because we're only talking about going off the limits to improve performance. That would allow keeping the safest possible track (gravel reduces your ability to brake before barrier a lot!) and still gives a real incentive to avoid going off the limits.

@studlydudly Exactly this! The F1 regulation has been changed a lot and the modern regulation is more gimmicky: bans on changing car mechanically, requirement to use at least two different tyre compounds during the race even if it slows you down, requirement to use intentionally inferior tyres (the tyre manufacturers are required to manufacture soft rubber that must destroy itself in few laps no matter how much you baby the tyres), very very strict restrictions on aerodynamic surfaces of the car etc etc. F1 cars had to run the whole race on single set of tyres in 2005 but somehow we should think that after 20 years of additional research, modern tyres should only last a few laps?
1
@kspectre21 I guess it depends on what you consider "good enough". For me, a single crash a day is borderline acceptable, RAM or VRAM leaks are not acceptable at all and sudden latency spikes that destroy minimim FPS are not acceptable. That's minimum bar for an acceptable release. Then we can debate e.g. if the simulation is realistic enough for collisions or tarmac or gravel.

Great video! I hope you could get Jimmy Broadbent to drive F1 car as well because that would be insanely good collab.
1
Great video but I wish you stopped using clickbait titles. For example, this could have used title "Why F1 Banned this GENIUS Device: MGU-H" to avoid clickbait title and similar naming could be used for the whole series of videos about banned technology.

This is like bridge engineering: what's the weakest structure you can build that still accomplishes the task?
1
@ejv0wjc08gtsnoj0 Exactly. Modern multilink suspension (especially rear and it started with Ford Focus in the 2000's, I believe) steers the wheel according to the compression and if you modify springs, you should readjust the whole geometry. It also means that even a small problem with the spring will misalign your wheel geometry, too. However, when everything is adjusted correctly, the end result is that the car feels like going on the rails around the corners even when there's bumps on the road.
1
8:25 Wait a sec! Why cheap EV cars are not already using these motors? 3 kg per wheel would be acceptable unsprung mass for a road car and 4x 67 hp would be plenty enough for a typical family car. You could have 4WD + torque vectoring and skip the diff and cvt joints and lots of other parts, too.
1
9:00 Oh, the regulations have a HUGE loophole when engines are not included in the budget cap.
1
Lots of interesting details in this video! Are you going to do a video about all the changes needed to the ICE engine to be able to do this?

@amazingblyatman5760 For me the only bad part of the modern F1 cars is the tires. Year 2020 version was already bad with intentionally inferior tires that FIA requires go bad after a couple of laps instead of being the best the tire manufacturer could do. Year 2022 version with bigger wheels / lower profile tires is going to be even worse. Consider year 2005. The race length was the same and they weren't allowed to change tires during the race and the tires were still in pretty good condition at the end of the race. Modern tires explode after 30 laps.
1
Great video! I would have preferred water jet cutting for even cleaner cut and less dust. How much did that helmet weight before cutting?
1
I think the regulations should be changed to allow engine software to be modified at all times the car is not on the track. That means it could be modified for qualifying and during every pit stop the race day, too. That would allow more strategy options for the teams during the race, too. The Mercedes party mode that allowed the driver to adjust engine parameters during a single lap was a bit too much in my opinion.

Is there some reason torsion bars are not used in normal road cars? The suspension takes a LOT of room in normal road cars and torsion bars would allow much more interior space especially at the back of the road car. Do these wear a lot quicker, for example?

We haven't yet seen Russel with too many cars but from what I've seen this far, it appears that he is really fast to adapt to different cars. Ricciardo appears to be the other way around – he wants that the car is adapted to his style and if that cannot be done, the results are poor.
1
I think the biggest thing that should be fixed is the max width of the car. Reduce it by 20-30 cm and it would be much better. Everything else is less important. The reason every team is going to always build up to max width allowed is that with human driver, the cockpit always has some minimum size and minimum center of gravity. And to get that center of gravity through corners faster, you want to put the wheels as far away from the driver (sideways) as possible.
1
@simonwadd4038 Yeah, and I've later found out that the wheel guns are standardized / regulated, too, so if the gun doesn't have such feature it cannot be added by the team either.
1
So basically compared to normal manual transmission car, this has much smaller diameter discs, much stronger springs, uses titanium instead of steel everywhere and friction material is fully made out of carbon. And because the springs are so hard, the hydraulic system is run by the engine, instead of simple pedal connection as in normal cars. And most normal cars have just one friction disc and this has three. But other than that, it's exactly like the clutch in a Ford Mondeo with manual transmission.

Delta wings are used in supersonic planes because it's needed to combat some issues with supersonic airflow. Having delta wing shape for anything that goes slower than the speed of sound is more like a marketing trick instead of required for aerodynamics.

I wish modern F1 were continuum for this kind of racing: very little rules and let teams innovate. Right now F1 has truly insane amount of regulation. It would be much better to have teams freely innovate but to keep costs low, the team would be forced to sell the car after race for $1M. That way you wouldn't want to use insanely expensive materials and competitors could also see all your tricks after purchasing the car. You would need to constantly innovate if you wanted to have edge over competition.
1
2:30 Also imagine the forces on your hands without powersteering and hitting a pothole while landing a big jump.
1
Could you do video about how modern cars implement the adjustable suspension dampening because they no longer can put the dampener inside the coil spring to save space?
1
The problem is that rules are not clear enough so the stewards seem to decide practically randomly if the moves Verstappen does are legal or not.

@royd7760 This season was definitely something else. I've often written that if "Drive to Survive" was fictional series, it would be told to be too irrational for this season.
