I probably posted this over in the Saab thread, and I'm not exactly an AI 'regular' but here's me in our still-relatively-new-to-us 2000 Saab 9-3SE It has its issues, but it's still pretty much awesome.

After riding in my best friend's new Z06, I'm pretty sure you could do the same trick. Ok, besides having owned the biggest mistake in my lifetime (yeah, bi-turbo), let's use some math. The fastest any vehicle can accelerate on a flat surface while depending on friction between the wheels and the road is 1g=9.81/9.82m/s². If you can't reach forward while being under the influence of 1g, you're just scared or seriously invalid - as in no arms. Fun fact: The fastest a car can accelerate from 0-100 km/h is exactly 3.6 sec. That is if the friction between the road and driving tires is exactly 1.0. That will never happen on common asphalt and available tires. Reality is that the most slick asphalt and the best tires will provide you a friction coefficient at about 0.9. That gives us a min. of 4 sec. 0-100. Anybody that claims otherwise is a drat loving liar or just plain stupid. A lot of cars (my old somewhat tuned Peugeot V6 included) can manage to accelerate 0-100km/h on the edge of losing friction (spin the wheels). On a FWD reality says about 6-7 seconds (1 gear shift) on a RWD or AWD it's a little better since you shift the down force to the rear while accelerating, but any claim of 0-100km/h below 4.5-5.0s is a drat lie. I'll take your money from the dashboard.

Real life doesn't lie. (The problem with your analysis is that racing tires are better modeled as adhesion than pure friction) E: Also, accelerating at 1g continuously gets you to 60mph in ~2.8s, not 4s.

LO Technology posted:It's a couple of decades since I took me master degree in mechanical engineering.  You are rapidly becoming my favorite poster here, this 0-60 stuff plus the mechanical failures thread is just fantastic. Also, assuming a coefficient of 1.0, final velocity (26.8m/s)/ acceleration (9.8m/s^2) = 2.73 seconds to 60mph. Edit: 0.9 would still be 0-60 in 3 seconds Edit2: When you factor in downforce from aerodynamics, 0-60 in 2.5-2.6 in a Veyron is totally possible.

Your math is off, 1g=21.93mph. With a 1.0 co-efficient of friction the maximum acceleration is slightly below 3 seconds and there are road tires with above a 1.0 co-efficient of friction.
