Can anybody tell me why he didn't do 60% of the vehicles weight to calculate the Normal force?

something has baffled my mind! you calculated the friction coefficient. but is it the friction coefficient of tires vs road? it would be totally different if corvette lacked ABS using the same tires. (is it kind of related to the fact that tires are round? :D ) and also, it seems like this calculations are done regardless of vehicle's total weight. I would be grateful if you answer me.

I think the reason there is no manual is this car is so fast that If you had to manually shift it would break down all the part constantly vs if the car shift on its own with wouldn’t wear down or break any parts of the car internals but that’s what I think

Thank you the roll out is 🤔🤔yea don't get it!!

How much power does it need to achieve 2.0sec 0-60mph?

Could you debunk the wide-tires-equals-more-traction myth?

So youre saying a 2019 Zo6 is as quick as a base model C8 lmaooooooo

This car is gonna FREAKIN' SMASH EVERYTHING

Its doesn’t matter if its not exactly the fastest Corvette on a track. Among a wide array of supercars, the C8 is still an amazing performance bargain.

I like to smoke weed and try to follow the math!

This is my favorite EE video of all time, I've watched it a dozen times and reference it frequently to other people. Well done Jason!

I have been thinking that tires are always doritos. I just clarified that they are like donuts, not doritos

So does this mean that Hypothetically a really fat and heavy person can help make the new gen corvette go faster?

Corvette is so nice

You kind of lost me at Tires are round!! lmao~!!!!!!

And the dual clutch trans is the key to it all!

$20,000 buy a zx10rr 😂 9 seconds stock.the end...

Have they released the 0 to 60 time for the base c8 with sport exhaust? I bet its not dramatiticaly different to the z51.

not an engineer, but that was incredibly well explained! i wonder about the difference in braking efficiency caused by wt distribution. since it's all 4 tires, wouldn't just a change in F/R brake proportion negate any difference in CG?

I don't like the way you bandy 4 letter words around, and neither does my mother. She just asked me... "is he saying that awful 4 letter word Bobby...?"... I said... "Yes Mum he said Math". She made me clean my mouth out with soap....!

I hate when they say fastest...it’s the quickest 0-60 is a test of quickness now get it on a track and top speed tells you what’s fastest

He really doing maff

The Tesla pickup will handle 110% grade, with SpaceX option giving protection against omnidirectional roll up to 60 degrees. /s

*Quickest.

The Vette keeps getting vettier?! Car looks stunning.

I will let you know if the car shows up on January since there is a strike going on 😂😎

This car is actually the camera car of the Bugatti 300mph record breaking. It also bested the Thrust SSC (sarcasm) . I like the cat tho.

Hi there Jason :) I am fascinated in the grip versus acceleration equation. How is it derived- or better yet, do you have the version for Front Wheel Drive? Many thanks!!

Why doesn't someone put a motor that Jack hammers the tires into the ground on these cars so they launch better. Like a shake weight (yes that silly exercise equipment) that's powered by an electric motor that shakes down then drops the clutch.... That would up the normal force , right ?

Slower than a tesla :D

The base i can see with perfermonance exhaust can potentialy be still under 3. I mean u got the same horse power and torque as the z51 with less weight and drag on the car on it to begin with. Think its just a marketing ploy to blow 5k unless you are into racing or tracking the car when cornering performance comes into play but for a straight 0 to 60...no. and the allseason tires specially made for this car alone has a max of 1g . To get under 3 is like 0.9gs for which i seen on the forums. The summer tires have a max of 1.13gs which is way more than enough.

Still the best sports car on the planet for about$50000 auto trans is better than any manual gearbox and much easier to drive like he said, much better than a manual transmission everything on this car is top shelf, best braking, acceleration no body rust, why buy a Lamborghini for $250000or a Ferrari for one million, you can buy a car that can be serviced at a Chevy dealership, do not have to pay $1000 for a headlamp replacement, hear that 50/50weight distribution, perfect, mustang, Chrysler demon, etc, FORGET ABOUT IT Chevy is here again and here to stay forever, do the math buy gm stock and hold it like warren buffet does

I don't think you can use braking distance and frictional coefficient to determine acceleration because breaking uses 4 tires and acceleration uses only 2 tires.

Same principle that took open wheeled racing (F1, Indy cars, ect) to a mid engine set up.

The new 'Vette looks like it came straight outta GTA

0-60 in

Nice video! Videos like these, makes me want to drive these type of cars! haha! Yet, I have no money! lol

He said there will be a more even weight distribution in the 2020 so it’ll have the best braking distance.....it’s weight distribution is 40/60 where the 2018 is 50-50. How is 40-60 more evenly distributed than 50-50? Also won’t weight, brakes, tires, etc have an affect on braking? I know he’s super smart, but that doesn’t sound like it makes sense.

Bull! It doesn’t achieve under 3 sec 0-60 just because GM says so! Or LIES so, in order to increase demand even more before INDEPENDENT testing so that the car can fly out of dealerships. Come on! Remember the Hellcat launch not so long ago? That car didn’t achieve the quarter mile time Dodge said it would either, but y’all believed the hype anyway. I agree the C8 is going to be great, and I’m ordering a Sebring Orange one, but I expect Motortrend and all the others to show realistic 0-60 times in the 3.4 to 3.6 range BECAUSE physics doesn’t lie like big corporations. All the chalkboard mambo jumbo aside, the car is not exactly light, at around 3600 lbs, it is not AWD with particularly sticky and wide tires, AND it doesn’t even have Launch Control? (Even if it does, this car, while great, is still no lightweight McLaren with Launch). We have to wait for the Z06 to see sub 3 guys. Sorry.

Zr1 is as fast to 60

After all that. Which is faster, all wheel drive lambo or GTR? AND WHY? LOL

Traction is limited tho as .. power rises. 65 35 SPLIT NOW... INVITING OVERSTEER.

Perhaps I'm not enough of an engineer, but I didn't quite understand how you were able to use the braking distance (braking with 4 wheels) to figure out acceleration on a rear wheel driven car (acceleration with just 2 wheels)...? What you explained would make sense to me with a 4WD car, but I don't quite get it with only two wheels doing all the work to accelerate.

On the Z51 package of the C8 they say you get an electronic limited slip differential can you explain the different differentials and what the differences will mean to the new C8 please??

We done Jason I can’t wait to get one when I can affort it

Until an actual road test confirms the times, I’m not buying the 2.9

Mid engine, rear wheel drive.... welcome to the 90's

You have become behemoth in sub-count size, 👍.

Do someone really buys a car because it accelerates from 0 - 100 in 3 seconds? Or for its awesome driving dynamics?

I can’t believe you forgot to mention weight transfer

Allllllllll those extra gears. When will it be electric and simplify and get quicker?

Is round tires a speed modification? I wanna try it on my Hyundai

I think this is going to be a hit for chevrolet. Fast, capable, auto, value and Murica.

In Europe we figured this out long time ago. Just like that the metric system is much easier.

You forgot about aerodynamic dowfoce.

By the time (well, speed) aero comes into significant effect you're not limited by tires any more but by engine power.

I'm old and an ex-truck driver who can handle a non-synchro gearbox just fine. I got an automatic car on my last purchase because I couldn't break my speed-shifting habit. Decades ago I thought that manual transmissions were going to go the way of the buggy whip by 2020 and they very nearly have. Except for Nascar and the Trans-Am series I can't think of any major racing series where conventional manual transmissions are still being used.

This will be the ultimate new age supercar for the average American Joe.

4:05 Mu knew?

I am ordering the 1lt with z51 package. To me , even if the car does it in mid 3’s in the real world, thats a win. I m coming out of a regular mustang gt. I can’t wait.

I just bought a 2019 brand new vette today for 62K cad. Good deal and is the last year model c7. C8 is very nice, but I'm into longhood American muscle car. C8 is too much euro looking for my taste

To each their own I guess. Witness meeee!

That deafening silence you hear is caused by the European sports car mfg's inability to speak due to their jaw dropping faster than the Vette accelerates.

Jason you really should try to be more excited about your analysis & presentation, I'm just not seeing it ;)

.....everyone's C6 just got cheaper.

You sir, cannot talk about the demise of the manual in that fashion. Sad? It's not sad. Manuals are just not as efficient anymore. Aren't you an engineer?

Borat Sagdiyev: What kind of car can I buy that attract woman with hairless vagine? Car Dealership owner: That would be a Corvette.

Nice..."I BELIEVE "

Power, acceleration, and grip. 👍 answered the question

So basically when I put all this math into my calculator I get this equation : C8corvette= absolute beast

Thanks for the headsup on the tires...

at 8:40 is the most important information. Corvette C7 does 0-60 in 3.8 in perfect conditions, not 3.0 nonsense.

Awesome video as always Jason! Awesome car as we hoped Chevy!

The taillights looks ugly. It had that balance between pretty and aggressive look stripped away, plus it looks better with the engine in the front. No manual option means it's butt. Dual clutch and manual should be options on all vehicles.

Never got 2.95 to 60 in my Z06 like chevy claimed ...

@TheCh0wderp the A8 Z06 was 2.95 as well. I know some hit it with drag radials or on a prepped track, I do miss that car......

Joe Villarreal they claimed the ZR1 would get 2.95 seconds. Even then that 0-60 was probably achieved at optimal conditions.

What about aerodynamics and weight transfer?

60 to 0 in 90 feet. If the Vette driver decides not to go through that yellow light, don't be the guy behind him.

@Common Tater Watch it again. He quotes the braking performance of the c7, not the c8 at 3:40. The c8 stops significantly worse than my c7 does.

@Theplatinumog At 3:40. Also it's written on the board. Unlikely many street drivers would ever brake like that but still...

Not sure where you got your numbers. The c8 does 60mph to 0 in 115.1ft or 108.4ft with the z51 package

0-60 is sort of like 40 time or max bench press in sports. It's a somewhat accurate proxy for actual performance, but people get absolutely nuts about it because it is so easy/tempting to measure and make things apples-to-apples when, in reality, they are not.

Given the 60:40 weight distribution, what would be your hypothesis regarding the steering response (oversteer and understeer) for the new Corvette?

Maybe Motortrend is not wrong, if they heat they're tires up first and then do the test!

I hate this car.......because I can't have one.

porsche has known all this for 60 years with the 911s. its about time chevy figured out that a front engined sports car is flawed. yes i know the 911 is rear engined not mid engined but the weight distribution is the same.

The Corvette has been and seems to continue to be a truly amazing car! Really impressive! I can't wait to see it on the track. Thanks for the cool analysis, Jason!

IIRC, Tesla and Rimac are claiming their new electrical supercars will accelerate from 0 to 100 km/h in less than 2 seconds. How is then that possible? I guess that this is now a matter of tires, not engine. Are they then using some different rubber on tires?

Giving new meaning to, "Do the math"

Why doesn't anyone talk about the suspention? Say it enough it's true: Viper will be mid engine, AWD, self driving 0 - grocery store in 5 seconds... C8 FTW for bringing us this awesome car from a GM hater... Thank you. Hats off

Cup 2 had them on my RS

taking *average* accelerations ... last time I looked there aren't any engineers using high school math. Your peak mu will be quite a bit higher. you also forgot 2.5s for a RWD C8. There's a rumoured electric AWD coming.

I did care about the frictional coefficient...

Great stuff. I am a current C7 Grand Sport owner. Don't forget the tires on the current wide bodies (GS, Z06, ZR1) are 295f, 325r which will make the frictional coefficient even higher assuming they use the same tire sizes when they develop the more track worthy models of the C8. Crazy stuff.

Hi Jason, you are calculating frictional coefficients from braking where most of the work is done by narrow front tires, so is it not going to be higher during acceleration when most of the work is done by wider rear tires? Or maybe this difference is negligible when taking into account that braking is done by all 4 tires and accelerating in this case only by 2 tires?

The g force of braking will never be as accelerating because of weight distribution but it's a good enough estimate, even if it was 50/50 you also have different gravity centres of the back and front, also the front and back tires aren't the same in most of sport cars.

what a bad ass channel. im a "theoretical engineer" (I write software ;) ) but I love engineering in all art forms. Automotives to lawn mowers. Canons to guns. robots and motion

I always wondered if tires were actually round or if it was just fake news. I feel more confident that tires are in fact round. Now if we can just get an engineer to prove climate change right or wrong, I think we’re set.

As far as I know the longitudinal friction coefficient is different for accelerating and braking due to directional nature of the tire. Also you're not taking load sensitivity into account which is an important factor. Basically all of the math is good for a coarse guesstimate.

I got a BMW M2 commercial while watching this video.. cool

I'd like to know how a DCT launches compared to a torque converter transmission. Surely this must be a factor too?

Doesn’t look like a vette. Looks like a Ferrari

You lost me at the dual clutch. They aren't that reliable. Ok , there crap. Ford found out the hard way.
