Asked the question, "Why do a ZR1?" Corvette Vehicle Line executive Tom Wallace shoots back, "Because we can. We have the technology inside General Motors to do a car that can go up against any supercar from around the world," he continues, punctuating the thought with this threat: "I can't wait to take on any Porsche with this car, and we're going to be right in there with the Ferrari [599s] and Lamborghini [Murcilagos]." Whoa, ease off the Red Bull, Tom. This is a just a souped-up C6 Corvette, right? Or did you slip a mid-engine V-12 in without the blogosphere noticing?
An hour with chief engineer Tadge Juechter reveals that this is indeed a Z06 upgraded with the best tech in GM's arsenal. A ZR1 was never part of the original C6 plan, but, at an early program review, the Z06's proposed aluminum frame, carbon-fiber parts, and LS7 engine so impressed CEO Rick Wagoner that he reportedly wondered aloud, "Geez, if that's what you can do with $60,000, I wonder what a $100,000 Corvette would look like?" With no more formal authorization than that, Juechter's posse launched a skunkworks effort dubbed "Blue Devil"-a nod to the boss's Duke alma mater.They started with turbochargers for efficiency's sake, but switched to supercharging when Eaton unveiled its latest four-lobe Roots-type blower. This new unit boasts thermal efficiency of nearly 76 percent (up from some 60 in the best three-lobe blowers)-near turbo efficiency with no lag.
