Shelby GR-1 is Taking Ford's Performance Car Future in a New Direction
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 supercars. 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 combines modern sculptured surfaces and a sleek muscular fastback design into a car that could succeed the Ford GT once its production cycle concludes. 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.
Shapely Exterior
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 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.
In the rear, a distinctive Kamm tail tapers to improve wind drag and features integrated transmission cooler outlets and a ground-effects venturi. It is further defined by a strong concave section and bold vertical taillamps.
Racing-Inspired Interior
The Shelby GR-1 concept's butterfly doors have distinctive teardrop-shaped side-glass graphics that create an elongated appearance, blending seamlessly into integrated door-release handles.
The interior door panels feature air-vent apertures and integrated "door close" pockets. The door release employs a pull-ring themed design with quick-release slide action and an illuminated door lock/unlock indicator. The exposed rear bulkhead cross-car structure braces to the roll hoop and features a snorkel air-register outlet that controls the ambient cabin climate.
The center console features integrated toggles that control the fuel pump, ignition, windows, hood and rear-glass release. The race-inspired push-button starter and "baseball grip" gear knob are situated ahead of the parking brake, which has been incorporated into the tunnel armrest. The quick-release steering wheel has integrated headlamp, wiper and direction indicator controls.
Supercar Powertrain
Inspired by the biggest, baddest engine of them all – the renowned 427 – Ford engineers created a new aluminum-block V-10 to power last year's Ford Shelby Cobra concept. This 390 cubic inch, 6.4-liter engine, reprised for service in the Shelby GR-1 concept, is adapted from Ford's MOD engine family. It delivers the rush of raw power – with 605 horsepower and 501 foot-pounds of torque – associated with that big 1960s V-8 powerplant without the aid of supercharging or turbocharging.
This combination of brute force and thorough engineering has created a rarity in the world of auto shows – a concept car that can actually do, rather than merely promise, 0-60 in under four seconds, and would easily exceed 200 mph if not electronically limited.
"After I drove last year's Cobra concept, I knew we had a winner in the 6.4-liter V-10," says Carroll Shelby, renowned race driver and consultant on the Ford Shelby GR-1 concept. "We decided to transplant that engine directly into the GR-1 with practically no changes, right down to the rear-mounted transmission, which really helps the weight distribution."
Unique Solutions
Additional improvements from the Ford Shelby Cobra concept include new, twin fuel fillers exiting the bodywork just aft of each sideview window and mid-way up the rear quarter panel bodywork. These racing-inspired devices feed two individual 10-gallon capacity fuel tanks that reside inside the structural chassis directly behind the passenger compartment.
The battery was also relocated to the rear of the vehicle, deep inside the luggage compartment, further aiding vehicle weight distribution and better shielding the battery package from the intense heat of the engine compartment. A new cooling system, evolved from the Shelby Cobra concept, includes a unique hood with twin portals to feed air into the engine compartment.
