NASCAR.COM - Daytona test speeds - Jan 16, 2008

From the Hendrick Team, where all four cars are essentially the same:

Earnhardt: 185.820
Johnson: 184.782
Mears: 184.574
Gordon: 183.809

Johnson & Gordon have the same shop . During the week, each Team wears identical Hendrick shirts, not their Team sponsor shirts. On a 2.5 mile track, the speed/time difference is significant regarding track position

Interesting to note that the fastest time was 185.820 ( Earnhardt ) and the slowest was 176.856 for 56 cars tested

A common complaint, unfair competition, in the past is the rules favored one make over another regarding the aerodynamics, In the pros and cons of specs, seems to now be a non-issue

That is why I don't like a Nascar mandated car. Make the car be the same shape as the real production car Then it puts the burden on the Car Manufacturers to make a better car for racing (the public also benefits from this). I also don't like the "all chevys run impalla, fords run fusion, etc..." If one team like the Monte Carlo over the impalla and they build a car that meets the body lines of the production car, let it race.
