Reception and sales
Although it was a highly innovative vehicle in a technical sense, the FF was not commercially successful. Its price was high — about 30% higher than the Jensen Interceptor, and more than that of luxury GTs from much more prestigious makers. In the UK a reputed 320 to 330 examples of the Jensen FF V8 model were made by Jensen Motors Limited according to The Jensen Owners Club.
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. In particular, the central

Appearance
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. The frontal appearance was revised in September 1968.

in the U.S. Further Hemi engine equipped models were not built, due to the limits of the suspension at extremely high speeds, and the cost of importing the Hemi engine into Britain, which was deemed too great.
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. Less than ten are thought to have been built.
Models
Dinky Toys produced a die-cast model of the FF, available in both ready-constructed and kit form. Playart also produced a 1:64 scale FF, possibly scaled down from the Dinky model.
The Dinky car had opening doors and both the Playart and Dinky models featured an opening bonnet (hood).
