3,524. That's too bad but I think this is a case of be careful what you ask for. People wanted Euro-refinement and appointments (so they say). Still, it will be very good. But it appears the days of the 3,100 lb Z06 are gone.
The good news is the famous Corvette trait of convertibles not weighing more is still intact, as the Z06 convertible is 3,582 lbs.
Incidentally, this is 171 pounds heavier, according to Chevrolet, than the 2013 Corvette ZR1 and 325 more than the 2013 Corvette Z06. Such is the price of more sophisticated suspension hardware, structural enhancements, plus a fat Eaton supercharger and all of its attendant plumbing on the 6.2-liter LT4 V-8.
