Having been announced at the Geneva Motor Show in March 1966[3] 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.

[4] 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).

Disc brakes were fitted to all wheels and recirculating ball-type steering gear was used with power assistance optional.

[4] In August 1967, it was announced that production of the Park Ward bodied Alvis 3-litre had ceased.
