The powertrain was sourced from Chrysler, installing the second generation 6,277 cc (6.3 L; 383.0 cu in) V8 engine and 3-speed TorqueFlite A727 automatic transmission.

The Dunlop Maxaret mechanical anti-lock braking system had previously been used only on aircraft, lorries, and racing cars.

The FF also suffered from a design problem, and not one easily cured: the system was set up for a driver in the right-hand seat, and no considerations had been made to making it left-hand drive.

The FF may be distinguished from the Interceptor by a few styling cues, the most obvious being the twin (rather than single) diagonal air vents on the front wing, just rear of the wheel-arches.

This version was equipped with a 7.2-litre (440 cubic inch) engine with a "Six Pack" induction system (three 2-barrel carburettors) as well as four-wheel drive.
