At the end of the day, we strapped on the old VBox and grabbed some acceleration and braking numbers on the long flat straight and were impressed. Acceleration-wise, it's a testament to repeatability, overlaying almost exactly on our 2010 Performance-Package SHO with a 5.2-second blast to 60 mph and a 13.7-second quarter mile at 103.2 mph (0.2 mph faster than the last one). Braking, however, was a big improvement at 106 feet versus 112. There was no chance to get figure eight numbers, but you can expect lap times to drop and overall g level to rise with the improved braking
So the PP is 0.2 faster in a quarter mile.Z
