The GT-R and Italdesign both celebrate their 50th anniversary this year, so Nissan and the Italian design house decided to collaborate on a very special project. The result is the striking GT-R50 by Italdesign, a one-off build to celebrate all things GT-R as well as show off the talents of Italdesign's crew. Right off the bat we'll tell you that the GT-R50 isn't the next-generation R36 GT-R. That point was stressed by Nissan design boss Alfonso Albaisa, who described the car as a GT-R without limits.
