Ford Shelby GR-1

The Ford Shelby GR-1 is a concept car developed and manufactured by Ford. It was first shown to the public at the 2004 Pebble Beach Concours d'Elegance as a clay model, and a fully functional concept was revealed at the 2005 North American International Auto Show. The design was inspired by the Shelby Daytona. Much of its chassis and running gear comes from the Ford Shelby Cobra Concept, and the project was led by Manfred Rumpel and developed by the Ford Advanced Product Creation group. It uses a 6.4 litre all-aluminum V10 rated at 605 hp with a 6-speed manual gearbox, quoted at 0 to 60 mph in 3.9 seconds. In 2019 Superformance announced a limited production run of the GR-1 concept with a supercharged V8.
