F ord is committed to deliver fresh Mustang news every year. In 2007, good news comes early as America's favorite muscle car debuts as a grown-up four-door sedan.

The Ford Interceptor concept – based on a stretched Mustang platform – comes equipped with a manual six-speed gearbox mated to a Ford Racing 5.0-liter V-8 Cammer engine that delivers 400 horsepower and runs on E-85 ethanol.

Modern muscle
"The Ford Interceptor concept has the soul of Mustang but combines 'Built Ford Tough' attitude with the sporty elegance of '60s Ford sedans," said Peter Horbury, executive director, Design, The Americas. "This concept celebrates the best of American muscle. And if it looks familiar, it should. That's because we've translated the design language of last year's F-250 Super Chief pickup concept onto a car."

In terms of exterior design, the Ford Interceptor concept features substantial, sometimes brutish, surfaces and sections and the traditional rear-wheel drive proportion that includes a short front overhang, extended dash-to-axle ratio, low cabin and higher beltline.

As a nod to performance purists, the ultimate muscle lies under the powered clamshell "shaker" hood, which caps a thoroughly detailed engine compartment.

Making this a Ford are signature design touches, including the horizontal three-bar grille that is structurally integrated into the bumper beam as well as professionally applied "squircles" – or professionally square circles – inside and out.

Inside, for instance, squircles finished with Titan Metal painted inserts accent the Ford Interceptor concept's instrument panel, door trims, console, floor and four seats.

Its low-back seats, finished in thick black leather with exposed-edge seams and contrasting stitching, modernize muscle car seats through their design – along with clever touches, including headrests that deploy from the roof.
The concept's minimalist interior is sleek, focusing the driver's attention on the speedometer and tachometer, whose needles start at center and move opposite each other.

The audio control panel and climate controls are hidden – but deployable. And the gated six-speed shifter is exposed, just waiting to be thrown into gear.

For safety, the Interceptor concept incorporates Ford's patented four-point "belt and suspenders" safety belt design in all four seats. This showcases a possible next-generation safety belt that is more comfortable and easier to use than traditional three-point belts. Additionally, inflatable belts have been included in the rear seat of the concept.

Legendary performance
The Interceptor concept's 5.0-liter V-8 Cammer engine is an upgraded variant of the 4.6-liter engine under the hood of the current production Mustang GT. The Cammer modular engine has powered Ford Racing's FR500C race car to the top of the Grand Am Cup's GS class, achieving 5 victories on its way to the Drivers, Manufacturers and Team Championships in its first season of competition.

Ford Interceptor concept shows new Mustang-inspired design possibilities – complete with two more doors and a "Built Ford Tough" design attitude.
