DETROIT – The Ford Interceptor Concept, to be unveiled at the 2007 North American International Auto Show in Detroit, rides on a stretched Mustang platform, with a Ford Racing 5.0L V-8 Cammer engine that produces 400 hp under the hood.

The mill is a DOHC version of that found on the production Mustang GT, Ford says, noting the engine also powers the Mustang FR500C race car.

The Interceptor also is E85 compatible and mated to a 6-speed transmission.

Design cues are borrowed from the F-250 Super Chief pickup concept introduced at last year’s show, Peter Horbury, executive director of design-The Americas, says. “This concept celebrates the best of American muscle.”

The exterior features large panels and surfaces, which Ford describes as “sometimes brutish.” Its traditional rear-wheel-drive proportion includes a short front overhang, extended dash-to-axle ratio, low cabin and higher beltline. A clamshell “shaker” hood rounds out the muscle-car styling cues.

The Interceptor also bears the horizontal 3-bar grille that is being widely used across the Ford lineup.

Inside are low-back seats, finished in thick, black leather with exposed-edge seams and contrasting stitching.

Innovative features include headrests that deploy from the roof and hidden audio and climate-control panels.

The Interceptor also showcases some upcoming safety devices under development by Ford, including a 4-point “belt and suspenders” seatbelt design in all four seats and inflatable belts in the rear.
