We're nearing the end of our testing in advance of CTS-V production launch. That means we've recently finalized some numbers. The SAE certified power is 556 hp and 551 lb-ft of torque. After our recent sub eight-minute lap at Nurburgring we also finalized some basic acceleration numbers. Zero to 60 mph is 3.9 seconds. We're doing the quarter mile in 12.0 seconds.

More to come in the next few days, including new video of our latest track
tests.
