Everyone saying 7:18-7:25 are crazy. That is Corvette ZR1 (w/ Sport Cup tires) and Dodge Viper ACR territory. The Camaro Z/28 will likely have 100+ less horsepower and weigh ~300 lbs more than the ZR1 and ACR Viper. What makes you think it will run those lap times?

I think the Z/28 will run 7:33.

We don't actually know the horsepower; GM said "about" 500 which you can take means more than that, they're just not sure how much more. Weight isn't as big a factor on a track like the Ring which GM proved with the surprising lap times of the ZL1. It's about suspension, spring rates, shock damping and tire grip. Stielow and team are clearly spending a LOT of time focusing on those areas. In those videos you can see a Vette, ZL1 and Z/28 running at the same time under the same conditions. That means they're studying the differences between lighter (vette) versus heavier but intelligent suspension (ZL1) and making adjustments to the Z/28 accordingly. Being out there all at the same time eliminates the variables of weather and track conditions.

Read up on the car projects Stielow has done and you'll realize what this guy can do. He's got the green light from GM management to make this a real track star and I'll be very surprised if this car isn't the fastest GM production car out on the ring. They're learning from what Stielow is doing so the high-performance version of the C7 Stingray will likely take back that crown next year but for now I believe the Z/28 is going to become king and surprise a lot of people. Yes I believe it's going to beat the ZR1's and Viper's times that are in the book.

So far, every video I have seen on the ZL1 and Z/28 at nurburgring shows the Z/28 going through a set of turns a second faster than the ZL1. Same day and same conditions. I don't know if it's my imagination or what, but that's significant.

Doc's a little more optimistic than I am, but if GM is going to make this a track monster, then they just as well do it right from the beginning.

Here's a short clip with ZL-1. It's about 2 seconds faster than the ZL-1 in the clip. But we don't know about how much the ZL-1 is being pushed and sounds like he slows down at the last curve shown.

The ZL1 is not being pushed in that clip. The Z/28 is going to be considerably faster.

If the Z/28 is beating the ZL1 by over 3 seconds a lap at the proving grounds in its current trim and testing stages, it will beat the ZL1's ring time by over 18 seconds.

ZL1 was 7:42.XX
Z/28 will be 7:23.50 or better.

I'm going out on a limb and gonna say 7:22.74
