The Nissan GT-R50 by Italdesign will make its world debut at the Goodwood Festival of Speed in Chichester, England, on July 12. The first-ever collaboration between Nissan and Italdesign, the GT-R50 prototype shown at Goodwood could become the blueprint for an extremely limited run of hand-built production vehicles. The vehicle commemorates the 50th anniversaries of both the GT-R, in 2019, and Italdesign, in 2018.
