The Mustang GT coupe concept, which debuted at the North American Auto Show in January of 2003, signaled a new direction for the 2005 Mustang. This car travelled to more than fifty auto shows around the world after its debut in Detroit 2003. The Tungsten Silver coupe interprets the performance edge of Mustang's heritage. The cockpit is dramatic for the driver and passenger with its glass roof and lush red and charcoal leather accented by billet-aluminum hardware. The cluster gauges, 3-spoke steering wheel and innovative cockpit dash design are clear cues from a rich Mustang history, but there is no denying that Ford's new Mustang GT concept celebrates that heritage in a dramatically modern interpretation of the future. Unlike production Mustangs, the Mustang GT concept has only two seats - racing-inspired with red perforated leather. Instead of a 2+2 design, the Mustang GT coupe's billet-aluminum strut brace linking the two rear shock towers serves as the primary hold down for a backseat mounted spare tire. The Mustang GT concept's adaptive headlamps are like technical jewels. Two concentric rings are shielded behind a single lens. The rings rotate in a helix pattern to zoom in and out like a camera lens. From a single light source, the Mustang GT concepts use fiber optic ribbon to deliver adaptable light levels through their highly focused lenses. An upward rake angle makes the car appear to be in motion even while at a standstill. The 20" wheels and 13.8" vented and cross-drilled Brembo disc brakes are pushed out to the corners and anchor the design to the road. A sharp accent line runs the length of the body just above the rocker panel and culminates in a "C-scoop" design behind the door cutline. The design creates an intentional visual link with the C-pillar design. The functional hood scoops help the Supercharged engine breathe as it churns out nearly 400hp. The engine bay boasts a MOD 4.6 Liter 90-degree cast-iron block V8 with aluminum heads, a belt-driven supercharger and a liquid-to-air intercooler. This concept car will be auctioned off for charity with all proceeds going to benefit the Juvenile Diabetes Research Foundation (JDRF)

The Mustang GT convertible concept, which debuted at the North American Auto Show in January of 2003, signaled a new direction for the 2005 Mustang. After its debut, this car travelled to more than 50 auto shows around the world. The Redline Red Metallic car features a distinct "showbar" with a rim of billet-aluminum trim picking up where the instrument panel and console trim leave off. This car started out with a significantly modified Ford Thunderbird rear-wheel-drive architecture. The platform was sectioned to achieve the proper proportion. The front-end geometry is all original. The 20" wheels and 13.8" vented and cross-drilled Brembo disc brakes are pushed out to the corners and anchor the design to the road. A sharp accent line runs the length of the body just above the rocker panel and culminates in a "C-scoop" design behind the door cutline to create an intentional visual link with the C-pillar design. The Mustang GT convertible's interior is awash in supple red and charcoal leather and accented with billet-aluminum hardware that gives an appearance that is robust and highly technical. The modern interior design pays homage to another era in Mustang history while the use of high-quality materials, precision craftsmanship and technical innovations point to Mustangs to come. Upon opening the door, both driver and passenger will see the Ford logo proudly displayed on a billet-aluminum sill panels. The interior includes perforated red leather surfaces on the seat backs and steering wheel, as well as a billet-aluminum shifter for the 5-speed automatic transmission, 4-point racing-style seatbelts and unique instrument gauges that look like a fine watch with its face removed. Four-point harnesses brace the occupants for what they see next. The cluster instrumentation is unique, but features a familiar, round optical look. Rather than using needle pointers, the gauges feature a small, gear-driven, trolley scored with indicator lines that rides around the inside of the bezel matching rpm and groundspeed. This concept car will be auctioned off for charity with all proceeds going to benefit the Juvenile Diabetes Research Foundation (JDRF).
