The
Jensen FF was launched at the 1966 Earls Court motor
show at the same time as the Interceptor. Although both
models were similar in appearance to each other, there
were significant differences between them with
a lot of the bodywork being unique to each car. The
FF front wings were longer and had double air
vents fitted to them (as opposed to the Interceptors
one), and the FF bonnet had an air scoop incorporated
in it, but the main difference between the two cars
was mechanical. The FF was a technically very advanced car
for its day and was the first British car to feature
permanent 4-wheel drive and anti-lock braking. Prior
to being fitted to the FF anti-lock brakes had only
been used on aircraft to enable them to stop more safely
on shorter runways. The Maxaret system used on the FF
was developed by Dunlop and used electronic sensors
on the wheels to eliminate the brakes locking. Harry
Ferguson, a tractor manufacturer developed the four-wheel
drive system, and this is where the FF name originated
- it stood for Ferguson Formula. Despite being voted
car of the year in 1967 by Car magazine, the FF did
not sell in great numbers partly due to the fact that
it cost approximately 33% more than the interceptor
and also export sales were low as it was only
available as a right hand drive model due to the layout
of four wheel drive transmission. Minor changes were
made during the life of the car and production ended
in 1971.
