The Alvis TF 21 was a series of luxury cars that were introduced in 1966. The TF 21, like its predecessor, the Alvis TE 21, was offered in saloon and drophead coupe body styles. These bodies were crafted by the coachbuilder Mulliner Park Ward, and powered by a 3.0L inline six engine that generated 150hp. This engine sent its power to the rear wheels via automatic or manual transmission options. The TF 21 would be Alvis' last production model, with the company ceasing automotive operations in 1967. At the end of production, a total of 106 examples had been built.
