[lbls1]

My best estimation would have to come from our present living example, being caddy's cts-v coupe. So far it dusted the gt500 (Thus no surprise that ford isn't waiting around for the zl1) and bmw m5 (They went off to turbo charging land after caddy's dispensed beating!), and it did this with the following (based on Edmunds):
4250 lbs.
4.2 0-60
12.2 1/4 mile
.90 g skidpad
104ft 60-0 stop time.

Having a fair idea of how chevy will handle the body and badge switch I'd wager that the zl1 would come in with

4000 lbs (It needs to be 3900 realistically)
4.1 0-60
12.2 1/4 mile
.93 g skid pad
104 ft. 60-0 stop time

Edit: Price...$49,899 base; 53-55k out the door....I hope

The zl1 can certainly improve on caddy's great numbers with some weight savings and really grippy tires.
