The Jensen FF was a four-wheel drive (4WD) Grand Tourer (GT) car produced by the British manufacturer Jensen Motors between 1966 and 1971. It was the first non all-terrain production car equipped with 4WD[1] and an anti-lock braking system — the Dunlop Maxaret mechanical system used hitherto only on aircraft, trucks, or racing cars. An experimental system was first fitted to a CV-8, but this did not go into production. The use of four-wheel drive preceded the successful Audi Quattro by many years.

The letters FF stand for Ferguson Formula, after Ferguson Research Ltd., who invented the car's four-wheel drive system. The FF was related to the similar-looking, rear-wheel drive, Jensen Interceptor, but is 127 mm (5.0 in) longer, and mechanically very different.


Reception and sales

Although it was a highly innovative vehicle in a technical sense, the FF was not all that commercially successful. Its price was high — about 30% higher than the Jensen Interceptor, and more than that of luxury GTs from much more prestigious makes.

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 transfer case and both propeller shafts protruded into the left-hand seat space. The steering gear and brake servo were fitted on the right-hand side, and there was no space for them on the left.[1] By the early 1970s, Jensen's primary markets were in overseas markets where cars were driven on the right hand side of the road (particularly the United States), and the FF could not be sold there.


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.

Only saloon (sedan) cars were made, there were no convertibles.[1]


One experimental Ferguson FF was built in 1968 with a 7 litre (426 cubic inch) Hemi engine imported from Chrysler 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 was deemed too great.

An "SP FF" version is rumoured to have been made at some point in the production run. 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 assumed to have been built.

Appearances in media

Modesty Blaise comic strips regularly featured her driving an FF, until a story where two villains push it over a cliff - while mentioning to each other that it is a shame to do such a thing to a hand-built car.


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 (with opening hood), possibly scaled down from the Dinky model.
