How the Ford Shelby GR-1 Works

Under the Hood

The GR-1 has much more than nostalgia and a pretty face going for it. An aluminum-block, 6.4-liter V10 engine is under the hood, cranking out 605 horsepower at 6,750 rpm and 501 lb-ft of torque at 5,500 rpm. That's enough power to hit 60 mph in under four seconds. Plus, the GR-1 accomplishes all this without turbocharging or supercharging.

The engine isn't mounted behind the driver's head the way it is in many high-performance cars. This is a more traditional front-engine design, created in part to fit the designer's idea for the car's shape. The transmission, a six-speed transaxle, is mounted in the rear to provide better weight distribution. This is another piece lifted directly from the GT.

The GR-1 also features a limited-slip differential and rear-wheel drive. An electronic limiter keeps the vehicle's top speed well under 200 mph -- a speed it could easily top if left unrestrained.
