Jan Magnusson, driver of the C6R Le Mans class winning car, drove 4 hot laps in a pre production Z06 recently. How good is the car? Lets just go down the Nurburgring Hall Of Fame.
Porsche Carrera GT (450,000)- 7 min. 32 sec.

Chevrolet Corvette Z06-7 min 42 sec

Porsche 996 GT2- 7 min 42 sec

Pagani Zonda S- 7 min 44 sec

Lambo Murscielago- 7 min 50 sec

Lambo Gallardo - 7 min 52 sec

Mercedes-Mclaren SLR- 7 min 52 sec

Chevrolet Corvette C6-7 min 59 sec

Porsche 911- 8 min 07 sec

Dodge Viper GTS- 8 min 10 sec

These numbers were taken from Motor Trends new magazine. The new Z06 turned this time on treaded tires not slicks. As you can see the new Z06 can definately live up to the hype.
