Stock tires

Yep, vid is in the OP's link now too, along with the rest of the info:

We just came back from Germany. As promised, here's the video of John Heinricy's sub-8 minute lap of the Nurburgring's Nordschleife.

To clarify, the car had no performance or operational modifications outside of what we intend to offer in production. We did have a couple of customary safety precautions, as the first goal of our testing is always to keep drivers like John safe. The car had a harness bar upon which a 6-way racing safety belt system was mounted. We also had a fire supression unit on board. These things add a little bit of weight to the car, certainly not helping performance any. Stock tires, too.

We had a chance to mount some cameras on the car and had the benefit of a beautiful day. Enjoy.

What I woudl like to know is how you put 700lbs of weight from one generation to the next...

According to caddy, the old one weighs 3500lbs... that has to be a typo...

According to other sources, the new one weighs 4200-4300lbs.

Wasn't the last generation CTS-V 3850 lbs? All of the specs I've seen put it right about there. It's probably just a specification error.

Cadillac does say the new one is about 4200 lbs (manual) to 4300 (auto), so it does look like it gained around 350-450 lbs. I would hazard to guess the drivetrain is at least 150 lbs of that (supercharger, plumbing, etc). The rest is probably the increased size, safety items, and luxury touches.
