The Alvis TF21 was the last car produced by Alvis cars. It was made in 1966 and 1967 and was an updated version of the 1963 TE21. Externally, the car was identical to the TE21, but there were some changes to the suspension, and, inside, the instruments were better organised. The 2993 cc engine, first used in the 1950 TA21, had its power increased to bhp (kW) at 4750 rpm by fitting triple SU carburettors giving the car a top speed of mph (km/h). A choice of automatic or five-speed gearbox made by ZF was available.
