There were Group A race versions of the previous model GT-Rs, which were basically stripped out versions of the regular production models but with several racing modifications. The previous V-spec cars, meanwhile, were developed to denote the GT-R’s racing success and included some serious performance enhancements as well.
There are several key details in these images, which turned up on GTR-World, revealing this is no run of the mill GT-R. Some of the elements the prototype features include a tow hook and pins protruding through the bonnet, a lowered ride height, race-spec alloys and tires, a modified front bumper (missing center grille possibly for improved airflow), full roll cage, a new air scoop in the front spoiler, a race-style refueling port and an air-jack adapter positioned below the right headlight.
While the GT-R is comparable with the Porsche 911 Turbo, the new V-Spec will follow the lines of the 911 GT3 in that it will be a bare bones version of the standard coupe and designed for the track but still road legal.
