In other words, the graph is pretty useless.

Thank you for presenting an interesting concept. I agree, in the 0-60 comparison weight/power and traction is king. Some of those cars are surprising, indeed. While mid-engine cars have a theoretical advantage, it is slight at best. The difference is more noticeable in the twisties.

On another note, question yourself, why does an arrow fly straight as an arrow? Hint, if it had its weight in the back it would swap ends.

I have watched a lot of side by side racing with a mix of front and mid engine cars, and everything else being equal, the rear engine cars almost invariably smoked the front engine cars early in the race. I did the same thing to a Mustang with an 80 hp Lotus. The drive wheels have better traction with more weight on them, the same reason that people in the snow belt put sand bags in their trunks.

I don't know where the data for the graph came from, but performance numbers from manufacturers are always suspect. The coefficient of friction of the surface for a 0-60 run is going to be a really important number and there is no standard for testing.

WHere is your comparative data on porsche 911s rwd non turbo 991.1 with manual transmission versus pdk ...

i would suggest you examine that comparative data to get an indication of potential acceleration improvement taking into account exact hp and tq as well as weight fir the c7 versus c8...

by my calculations we should see approximately 6 tenths of an improvement from the manual transmission c7 z51.

should the weight be the same between the rwo generations...an additional .1 of a second improvement should occur with 10 additional hp.

rough estimates yet a good rule of thumb to follow.

Please provide evidence of the HP output of all versions.

And DCT is only faster 0-60 if there is no 1st to 2nd shift.

JerriVette

Actually the launch control of the dct transmission makes a dramatic improvement in acceleration and that would not necessitate a first to second gear shift

please include that in your calculations

pdk launch control improves zero to sixty by .6 of a second....compared to the manual transmission.

easy to announce via reputable repeatable automotive journalist road test reviews ...

compare manual transmission 911 acceleration times versus pdk

vndkshn

But that’s very much an “it depends”. There have been documented times it was not.

JerriVette

With PDK technology there is a clear and present improvement of .6 of a second to sixty mph and in the quarter mike compared to manual transmission versions of the same vehicle.

Personally, I like 0-100-0.

On par with most posts on the internet.

Well the estimate is 3.6s 0-60 so we will see how close the OP is. Gee some people are so quick to critise give the guy a break. This is a forum after all and it is good to bounce ideas around.

Rkreigh

a good benchmark of raw performance was the 0-150-0

the reason they did 0-100 is early rides wouldn't bump 150

look up some of the cobra and zr-1 LPE times and it's pretty interesting stuff!!!

Warp Factor

Nice compilation, OP. However, anyone who owns a Z06 or ZR1 knows that they are severely traction-limitid at lower speeds, and that drag tires and track prep will significantly improve 60-foot times and ET.
On the C8, a higher proportion of the weight on the rear tires will improve traction over the previous models, and improve 0-60 times, all other things (such as power and gearing) being equal. It could suffer from not having a torque converter though (if it doesn't).

There will be other factors, of course, like what launch rpm the computer is programmed for.

Exactly

range96

Launch control modulates the throttle (engine), not the clutch engagement (transmission). There is launch control in both manual and automatic transmission equipped cars.

Dominic Sorresso

Also, u can include AA dragsters. Having said that, the move to mid-engine has much more to do w road course behavior and less straight line acceleration. But thx for the analysis.

911 GTS pdk 3335 lbs, 450 hp 0-60 3.0 seconds
Grand Sport auto 3430 lbs, 460 hp 0-60 3.6 seconds

.6 seconds, almost identical power to weight.

C8 is going to be much faster 0-60.

Glenn Quagmire

Earth to OP...unless you’re still in high school, NO ONE measures performance by 0-60 times.

So says the Zr1 owner, which has probably the worst time possible for its power to weight.
