The Jensen Motors stand at the October 1964 Earls Court Motorshow displayed a Jensen FF car equipped with all wheel drive and ABS as publicised but not displayed in February 1964. At the following Show in October 1965 a production ready CV-8 FF was displayed, priced almost 50 per cent more than the standard car and three inches longer. However, it remained a prototype and instead the Interceptor-based Jensen FF entered production in 1966. The letters FF stand for Ferguson Formula after Ferguson Research Limited who invented the car's system. The FF is related to the similar-looking, rear-wheel drive Jensen Interceptor but is five inches longer and mechanically very different. The FF is apparently externally identical to the Interceptor, although it was four inches longer in the bonnet (all ahead of the windscreen) and it had a second row of air vents behind the front wheels.
The extra letters stood for Ferguson Formula, Ferguson Research being the inventor of the full-time all wheel drive system adopted, the first on a production sports car. Also featured was the Dunlop Maxaret anti-lock braking system in one of the first uses of ABS in a production car.
Just 320 FFs were constructed and production ceased in 1971
