(from Ford Press Release) 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.
Sensuous, perfectly proportioned and wholly modern, this show car builds on the success of the Ford Shelby Cobra concept the 2004 North American International Auto Show (NAIAS) "Best in Show" winner and reinforces Ford's continued commitment to performance.
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.
A REALITY-BASED CONCEPT
Much like the original Ford GT and last year's Shelby Cobra concept vehicles, the Shelby GR-1 was intended to be a fully engineered, production-feasible roadgoing, drivable project vehicle.
"With the Ford GT and Ford Shelby Cobra concept, we have a tremendous amount of experience quickly building high-performance cars, like the Shelby GR-1, with world-class performance," says Phil Martens, group vice president, Product Creation. "Our goal this time around was not to create the ultimate top-speed, high-performance sports car. Really, we intended to strike a better balance of design, capability and usability that might appeal to someone considering a Ferrari 575M Maranello."
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 spaceframe 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.
"Building a concept car with this level of sophistication is much easier when you start with a world-class supercar like the Ford GT," says Martens. "This commonality and re-use goes hand-in-hand with our speed and cost efficiency, promising the Ford GT's bang-for-the-buck equation if the Shelby GR-1 goes to production."
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.
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 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.
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.
The Shelby GR-1 concept sits on 19-inch, 12-spoke milled aluminum wheels and features Goodyear 275/40R-19 tires in the front and 345/35R-19 tires in the rear, mated with the unique Tire IQ system, which allows the driver to monitor precise tire performance.
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 graceful upward glide of the doors leads into the race-inspired interior that features seats with carbon shells and fixed backs. The carbon shells are connected directly to the sill and tunnel via lightweight aluminum spaceframe attachments and can be adjusted fore and aft by way of an accessible pull ring on the seat cushions' leading edge. The seats incorporate removable Alcantara comfort inserts that are individually tailored to the occupants' body type.
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.
Interior cabin technology focuses on driver comfort, enjoyment and entertainment. The instrument panel sports a full complement of analog gauges, including a combination analog tachometer with floating watch-like elements and digital speedometer. The tachometer housing has integrated air registers and an additional Noise Reduction Technology (NRT) output speaker.
The centrally mounted Tire IQ display is a sophisticated driver's aid designed to inform, warn and even entertain. The Tire IQ system provides the driver and passenger with an animation of vital tire temperature and pressure statistics (via sensors in the tire), along with other key vehicle dynamics such as cornering G forces (via an onboard accelerometer).
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.
Special attention has been paid to noise reduction on the interior. The rear hatch stowage compartment features a removable MP3/Amp and NRT console, while audio input, output and recording speakers are integrated into the headrest protection wings on each seat. The speakers can provide a combination of the following:
Noise-reducing sound waves (NRT) for improved highway cruising noise levels
Play or record (for playback) pace notes
MP3 Audio
The MP3/AMP/NRT functions can be interfaced through the Tire IQ display through a joystick controller.
Throughout the interior, the leather trim is in slate gray, with color-matched perforated Alcantara leather featured on touch zones such as the gear knob, parking brake, steering wheel, door inserts, and instrument/Tire IQ binnacles. Functional zones such as dials, door release and center console switchgear have been finished in a combination of anodized gunmetal finishes.
Ambient cabin lighting is neatly packaged behind the central headlining panel; an indirect blue glow appears around the periphery offset of the panel. The headliner and upper doorframes are trimmed with a woven aluminum-metalized fabric that lightens the interior ambiance and heightens the slate grey tones of the leather and Alcantara trim. The dark gunmetal-gray flooring also is trimmed in the hard-wearing metalized fabric.
PROVEN CHASSIS COMPONENTS
From the outset, the Shelby GR-1 concept team intended the concept to perform at supercar levels but with a more "mature" feel biased a little more toward driver comfort than the Ford GT widely noted for its balance of dynamics and road manners and last year's Ford Shelby Cobra concept.
