In the latest episode of Head 2 Head, MotorTrend has put face to face two of the greatest sports car: the 2013 SRT Viper GTS against its domestic rival, the 2012 Corvette ZR1. The test drive was held at the Mazda Raceway Laguna Seca and behind the wheel was pro race driver Randy Pobst.

If you remember, at the end of 2012 there was a real fuss with the two models when MotorTrend announced that ZR1 managed to set a new Mazda Raceway Laguna Seca lap record with a time of 1:33.70, while the SRT Viper achieved a time of only 1:35.77.

This result was impressive, considering that both deliver pretty much the same output: 640 horsepower for the Viper and 638 horsepower for the ZR1. But we guess it was aerodynamics that made the difference, right?

Watch the video to find out which of the two cars has the bigger "bollocks."
