Shelby GR-1 Concept from Ford

The Ford Shelby GR-1 concept springs from a long line of Ford performance project cars and quickly establishes itself as one of the most contemporary and dramatic front-engine, two-seat, fastback Supercar. This running prototype reaches closer to reality with a 605-horsepower, 390-cubic-inch all-aluminum V-10 engine, a road-tested version of the Ford GT suspension and a stunning new polished-aluminum body.

The Shelby GR-1 concept's name pays tribute to both a performance great and "Group Racing." This uniquely emotional American sports car design represents Ford's continued desire to include a high-end, limited-production specialist Supercar in its lineup. Initially unveiled as a design exercise at the Pebble Beach Concours d'Elegance in August, the Ford Shelby GR-1 concept is a sports car salute to "performance art."

"A perfect body with smooth, shimmering aluminum skin, the new Ford Shelby GR-1 concept is a rolling sculpture whose beautiful, flowing lines belie the raw, beastly V-10 wedged under the hood," says J Mays, group vice president of Design and chief creative officer. "This concept shifts gears and takes Ford's performance car future into a new direction."

The Shelby GR-1 concept combines modern sculptured surfaces and a sleek muscular fastback design. All of the sophisticated mechanicals of this extraordinary coupe are wrapped in a sleek, muscular aluminum skin left bare and polished bright. The result is a forward-looking Supercar with attention-grabbing Ford presence and Carroll Shelby inspiration.

The Shelby GR-1 starts with a modified version of the aluminum chassis from the rear-engine Ford GT. The bulk of the rear structure is made from slightly modified Ford GT components, including the massive trellis-like, cast-aluminum suspension nodes, the rear rails and bumper beam, a major cross-member and the brackets used to mount the transmission.

The center portion of the space frame also borrows liberally from the Ford GT as major aluminum extrusions are based heavily on existing pieces. At the front of the coupe, the team incorporated extruded main rails, a steering rack cross-member, crash-management sections and the bumper beam from the Ford GT.

Overall, the Ford Shelby GR-1 concept is more than two feet shorter than the Ford GT, with a wheelbase nearly seven inches shorter. The track width has been reduced by more than an inch. That the concept car and the GT share any parts at all is a testimony to the flexibility of the space frame design and the creativity of the chassis team.

The Ford Shelby GR-1 is a sinewy, athletic design with a long hood that blends seamlessly into the teardrop-shaped cabin with a fastback roofline and falling upper fender line. The car looks as if it is in motion, even when it is standing still.

The optimized wheel arches and compact overhangs define the striking stance while the strong shoulder line and smooth, taut surfaces express the car's graceful yet athletic nature. The polished aluminum body panels further express the highly sculptured surfaces and define the emotional proportions in dramatic fashion.

The front of the Shelby GR-1 concept is dominated by an air-intake aperture and airflow splitter, directing cool air into the engine bay and wheel wells, while air vents on the upper surface of the hood exhaust hot air from the radiator. Additional intakes and vents perforate the body side to ensure cooling throughout.

The front corners of the Shelby GR-1 are dominated by substantial front wheel wells housing 19-inch wheels and tires and trapezoidal High Intensity Solid State (HISS) headlamps that float above the wheel arches. This highly technical lighting package provides powerful illumination in a very compact package, allowing freedom of design without sacrificing nighttime driving visibility.

For this reality based concept car, the ultimate test was a session at Ford's Michigan Proving Grounds. The team spent several days doing a lot of dynamic vehicle development, including shock, stabilizer bar and spring tuning, and a variety of testing and development work to make sure they had a competent driver's car that would handle well and be safe to drive at high speeds on a test track. That puts the GR-1 approximately a year ahead of where the Ford GT was at show car time.
