Just read this this morning and found it pretty interesting:

0-60 time will be 4.1 sec (manual) 4.3 sec for paddles and 3.7 sec (Z06)

1/4 mile will be at 12.4 @ 117mph (manual) and 11.7 @125mph (Z06)

Top speed 190mph (manual/A6) and a whopping 198mph for the Z06!

I heard it was going to be 430 HP, is that what you read? Still using the LS2?
