The Jensen FF is a four-wheel drive grand tourer produced by British car manufacturer Jensen Motors between 1966 and 1971. It was the first non all-terrain production car equipped with four-wheel drive and an anti-lock braking system.
The letters FF stand for Ferguson Formula, after Ferguson Research Ltd., who invented the car's four-wheel drive system. The FF is related to the similar-looking, rear-wheel drive Jensen Interceptor, but is 127 mm (5.0 in) longer, and mechanically very different.
Standard FF features included front seat belts, a tachometer, and map pockets.
