The Alvis TF21 was the last car produced by Alvis cars. It was made in 1966 and 1967

History

The car was 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 3-litre saloon was presented at the 1955 Geneva Motor Show In the version with the coachwork by the Swiss designer Graber; in 1958 Park Ward designed new body which slightly modified the design of the earlier model in order to make the interior roomier. The name of one of the most classic British coachbuilders is in itself sufficient to give a clear definition of the car's characteristics. It is a typical English product. bound fast to the finest traditions and rich in all the qualities that can derive from a careful choice of materials and exceptional precision of workmanship. 
The only novelty in the styling of four headlamps. Technically, leaving most of the well-tried solutions, only the maximum power of the engine has been changed: this has been increased to 150 hp at 4,750 rpm. The chassis still has a layout that has nothing modern about it. It must however be recognised that not only is the behaviour of this Alvis excellent (also when driving over rough road surfaces or even off the road), but it really gives the impression of traveling in a body integral with the frame. With a distribution of weight of 52% to front axle, and 48% at the rear axle.
As should be the case with a car of this class. noise is kept within strict limits that are well below the average. both because of the particular of the mechanical elements and the careful isolating of the interior.

The interior has all the usual finishing of the high-quality British car: fine wood is used for the facia. the design of the instruments is highly functional. the seats upholstered in leather and the floor is carpeted. Everything. in fact. contributes to making this a pleasant car to get into and, what is more.to do a long journey in.The instruments are grouped on a panel behind the steering wheel and include a speedometer. rev counter. oil pressure gauge, petrol and watergauges and an ammeter. There is also an ignition warning light. combined ignition switch and starting control plus a choke warning light.Access to the rear seats presents no difficulties. due to the fact that the doors are unusually wide for a car of this size. No criticism can be made of this Alvis as far as interior width or leg room are concerned. and it should satisfy all the requirements of the most comfort-conscious passenger. A particular word of praise is deserved by excellent ail-round visibility. The 2993 cc engine, first used in the 1950 TA21, had its power increased to 150 bhp (112 kW) at 4750 rpm by fitting triple SU carburettors giving the car a top speed of 120 mph (193 km/h). A choice of automatic or five-speed gearbox made by ZF was available.
