I was just searching around, and when I came accross motor trends website I saw this
http://www.motortrend.com/roadtests/..._gt_first_test
worth noting
0-60: 5.3 sec
1/4 mile: 13.8 s @ 102.8 mph
skidpad: 0.88g
60-0: 112 ft
51/49 front-rear weight distribution
15/24 mpg
there you have the first set of numbers on North Americas first Zeta. The mileage is slightly disapointing considering the VVT and AFM. then again, the GT weighs 4096 lbs. I really hope the Camaro base v8 weighs a few hundred pounds less.
