Porsche 911 Turbo

Porsche = Lighter, has more tourque, demands more $$$
Nissan = GTR

Nissan GT-R vs Porsche 911 Turbo – it's the clash of the year. And CAR has pitched the benchmark Porsche against the first GT-R to arrive in the UK, and you can watch the video at the foot of this page.

Two blown, four-wheel drive cars, each nudging the 500bhp mark, head-to-head on Rockingham's infield circuit.

Also, this is a great read for the GTR lovers
