0-60 mph: 3.8s
0-100 mph: 8.4s
0-150 mph: 20s
1/4 mi: 11.9s @120 mph
Top speed: 185 mph (virtually unchanged compared to existing car)
N'Ring: 7:36 - 7:42 (will strongly depend on tires, driver, conditions, etc.)
Today I read in the new Roundel (Jan., p. 30) that, "test engineers have coaxed the GTS around the legendary Nurburgring Nordschleife in seven minutes, 40 seconds - ten seconds quicker than the E46 CSL".

I'm pleased with my predictions. Withing range and even close to the middle of my range.
