Tiff Needell with Porsche 911 Carrera S and Nissan GT-R

Few rivalries are as heated as that between the Nissan GT-R and the Porsche 911. And with both models having recently been updated, Evo magazine has taken the updated GT-R and the new 911 Carrera S to the Bedford Autodrome for a little head-on-head action. And who better to put in front of the camera and behind the wheel than Tiff Needell, the longtime Fifth Gear co-host who's now doing a series of video tests for the magazine British enthusiasts love best.

Now if you're thinking that the GT-R really ought to be compared to the 911 Turbo and not the naturally aspirated 911 Carrera S, well, you're probably right. Particularly since Nissan hiked the price on its latest performance flagship to nearly $100,000. But Porsche hasn't released the turbocharged version of its latest 911, so the Carrera S will have to do. Skip past the break to see how they compare, as well as which one is Tiff's favorite.
