Not really believing the vette can out perform the McLaren, I did some research on this.
The vette must have had the Z07 package. Why do I say this. Upon inspection of the times, in all situations the McLaren is a faster accelerating car, so the vette must have won on braking.. How is this possible you ask. Simple, tires.
the Z07 vette has R comp tires. But so does the McLaren...
Lets examine size...
Vette: F 285
McLaren: F 235
Vette: R 335
McLaren R 305
The vette must have won on the brakes, and powering out of corners with its massive tires giving it tons of grip.
Still for comparison, the top gear test track has the Mclaren 20+ spots ahead of the Z06
So go figure..
