The 2005 Ford Shelby GR-1 Concept is a one-of-one fully functional concept car inspired by the legendary Shelby Daytona Coupe. Its mirror-like finish is polished bare aluminum, not traditional paint, and underneath sits a 6.4L naturally aspirated V10 making 605 hp and 501 lb-ft of torque, paired with a 6-speed manual and rear-wheel drive. Ford estimated 0–60 mph in under 4 seconds with a potential top speed of over 200 mph, making it one of the wildest Shelby concepts Ford ever built.
