Jensen FF

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 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, based on the chassis of the Jensen 541S, but this did not go into production. The use of four-wheel drive preceded the successful Audi Quattro by many years, and by Subaru five years later.

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.
