Tyre Size: 185/80R15 (185R15), Tyre Diameter: R15, Profile: 80 | Jensen Interceptor FF Mk1 1966 to 1969

Ground-breaking version of the Interceptor, with 4 wheel drive and anti-lock brakes. Produced from 1966 to 1969. Originally fitted with a 670-15 crossply tyre with the highest available speed rating, with the option of a 185R15 radial offered during production. If a radial tyre is required, then a 185VR15 is the best replacement size.

The Jensen Interceptor and FF arrived in 1966 with a 6.3-litre Chrysler V8. Whereas the Interceptor featured rear-wheel drive, the FF's power went to all four wheels and its wheelbase was four inches longer to allow for the extra transfer case up front.

Jensen announced a Mk2 Interceptor and FF in 1969, with a reprofiled nose, stronger brakes and standard power steering, then in 1973 the Interceptor Mk3 appeared. At this point Jensen axed the FF and the Interceptor SP (six-pack, for six carburettors) took over as Jensen’s flagship; while the regular Mk3 produced 300bhp, the SP had 385bhp.

In November 1971 for the US market (May 1972 for UK buyers) a 7212cc engine replaced the previous 6276cc unit. The fuel crisis of 1973 led to the demise of the SP; an Interceptor convertible was launched in 1974 but Jensen went bust in 1975 and closed down in 1976. By this point 6408 Interceptors had been built along with 320 FFs. Jensen returned in 1983 to have another go, but just 14 Interceptors were made before the company closed for good.
