The Vette should be very close to the GT2RS times. Similar horsepower, probably less weight, fast shifting auto trans, etc.

Also, the Vette racing program has been solid lately and likely spun off a ton of good R&D that GM has by now had plenty of time to digest (i.e. how to resolve the cooling issues on the Z06).

I think both cars are going to be terrific and it will be fun to see which is fastest.
