I'd be a bit worried about aerodynamics in these cars at those speeds. Originally Posted by threethirtyfive. Check out this list - 5th one down.

In a i with whp, if it would even hit mph eventually, I would guesstimate you'd need a couple miles of straight-away at least for accelleration.
And you need enough space a mile or two I presume for safe deceleration. A i would have to be specifically and carefully prepped aerodynamically for a mph run. Originally Posted by LessIsMore.

James May on Top Gear did his top speed Bugatti run at VW's own test track for the Bugatti, not many places in the world are suitable for such a run. In a i with whp, I would guesstimate you'd need a couple miles of straight-away at least for accelleration.
Any vehicle would need a couple miles for safe deceleration. And in terms of safety, a i would have to be specifically and carefully prepped for a mph run - fron the factory, the car would not be stable. Those aesthetic "lip spoilers" most people buy would not cut it. Originally Posted by natedog I got curious and searched after my original post - see my edited post above now with link.

On the same subject, a Michelin engineer told me that a good rule for them was to divide the unloaded tire diameter into 20, to get loaded revs per mile.

Sure, if you are on the throttle, there will be slip. Have you seen any type of formal characterization of this effect on a straight line? Didn't get into that, sorry. Saw some stuff from the SAE way back when we were working on a quarter-mile simulation, but it was info in regard to the effect of slip on coefficient of friction.
Never looked for it in that precise way, though. You might try to check in with them. Last edited by crypticc; at PM.. Private First Class.
