The new 2009 Viper ACR pulled a 7.22 at the Nürburgring recently. This beats out the new GTR and the ZR1. I'd say it's impressive being it's just and engine and gearbox with four wheels and a body. No AWD, no yaw sensors, no ACD, no traction control, no electronic nannys and it still takes the record.
I'll bet if they raised the limiter another 200-300 RPM they could keep from bouncing off it so much. It would also help if he didn't miss that shift. Between those tow things I'll bet they could shave off another five tenths.
