I've already seen the test, if you or anyone else would like the full article i'll happily post it.
Anyways, the Z06 is a rocket and it's Hockenheim time is amazing. Cars in that 1:11 -- sector include:
996 GT3RS: 1:11.8
Zonda S: 1:11.8
997 GT3: 1:11.7
996 GT2 MK2: 1:11.6
It's extremely close to the Pagani Zonda F too: 1:10.8
