Was the GTR a tip? I assume so by the lack of apparent changing of the gears. I concur that the GTR driver even seems more relaxed in his efforts at least in the first three minutes.

The ZR1 hit a top speed of 179 best I could tell. I also concur that it seemed the GTR handled the effort easier. Could be the car, could be the driver. Hard to tell. The ZR1's driver had a lot more inputs on the wheel.
