GM trots out 'Vette with 620 horses - American supercar (1) - CNNMoney.com

Two things that stand out to me.

1. Carbon Ceramic rotors. Lifetime rotors! Yeah, its about time.
2. Magnetic Selective Ride Control - I dont know this for fact, but I remember a special on Discovery channel a couple years ago that dealt with upcoming or futuristic automotive technologies. One of which was shocks and struts that used a material in them that replaced the normal fluid that was kinda fluid but changed with electrical current. In otherwords, the suspension was completely dynamic and near infinitely adjustable. The more current applied the stiffer the ride, but it could also be set up to apply current in a progressive way so that the faster the shock was rebounding or dampening the faster the current was applied and so gave a near perfectly consisten ride no matter the road conditions.

I dont know for fact that that is what is on the Corvette, but it sounds like it.
