BEST IN SHOW
CHEVROLET CORVETTE ZR1

Cynics might say the 2009 ZR1 is nothing more than a Corvette with a bad-boy V8 stuffed into the engine bay--a stance taken initially by some AW editors, who questioned its Best in Show worthiness. But that line of thinking sells this supercar short.

Yes, the supercharged 6.2-liter LS9 will produce at least 620 hp and 600 lb-ft of torque, putting the ZR1 in the upper echelon of the numbers game, no matter who comes out to play. It also features an adjustable suspension, carbon-fiber bodywork, some unique exterior pieces, carbon-ceramic Brembo brakes, variable steering and a close-ratio six-speed gearbox.

The sum is a whole lot greater than the collective parts: This is a JATO rocket on wheels that moves the Corvette up yet another rung on the performance-car ladder and leaves almost all competitors jinking like an F-22 Raptor to avoid certain destruction. Perhaps more significant, new fuel-economy standards that mandate a corporate average fuel economy of 35 mpg by 2020 likely mean that Chevy--or any domestic automaker-will not produce a car remotely comparable to this one for years to come. So remember the 2008 North American International Auto Show as the first time you laid eyes on the most balls-to-the-wall factory Corvette of all time.

Still not convinced? Walk the floor, take everything in, and consider: Badge snobbery and concept cars aside, there is no other machine parked on the Cobo show floor that we look forward to driving more than the ZR1.
