Dunno if this was posted already.. Looks like the new Viper takes the cake, at least in the straight line department. And this pretty much shows the new C7 Z06 is a 125-127 Mph car as several tests show the new Vipers trapping 127-129 Mph and running 11.1-11.3 OEM stock. Kind of disappointed in straight line performance for the new C7Z, as almost 10 years back a Porsche CGT was going 11.1s at 132-133 in a torqueless 5.7L that usually put down 540-550 Whp, Not too mention a direct competitor base model GT3 managed 11.3 at 124 Mph earlier this year... I'm sure the new C7 Z06 will do better around the twisties tho.
