Which car will reign supreme when it comes to speed? The Nissan GT-R, Porsche 911 Turbo and BMW M5 Comp compete with each other in a drag race to find out which of the automobile worth £100,000 dominates in terms of speed. However, only one car is standard – the BMW M5 Competition. The Nissan GT-R has been tuned by Litchfield while the Porsche 911 is actually an older generation 997 that’s been modified by ES Motor.
