The Alvis Three Litre series IV, TF21, an updated version of the 1963 TE21, was the last car produced by Alvis Cars, having been announced at the Geneva Motor Show in March 1966 it remained in production until 1967. Externally, the car was identical to the TE21, but there were some changes to the suspension, and, inside, the instruments were better organised. The chassis and suspension continued with front coil springs and leaf springs at the rear. Disc brakes were fitted to all wheels and recirculating ball-type steering gear was used with power assistance optional. * *
