Looks like the right lane has the better traction for the launch as both cars got the better start in the right lane. The first run, the CTS V put on a lot of lead that the GTR could never make up. After switching lanes, the GTR got the jump even with the CTS V redlighting.
After the 60-ft point, they looked pretty even with the CTS V, maybe, having a little more than the GTR.
