Background
The Graber-styled TD21 brought a fresher, more modern look to the Alvis marque, even though the car was built on the same chassis as the heavier looking and rather dowdy TC21. Essentially a development of the TC108G of 1958 (built by Graber itself then coachbuilders Willowbrook), production was moved to Park Ward for the introduction of the slightly restyled TD in 1959.
The car utilized very similar suspension to the TC21; independent at the front using coil springs with leaf springs at the rear. Even so, the TD was lighter and stiffer than the TC and, with a wider track and with an anti-roll bar up front, boasted much sharper handling – as well as a 100mph-plus top speed.
From 1959 the model was offered with Lockheed servo-assisted disc brakes up front, and, from January 1962 with the introduction of the Series II, with disc brakes all round. Later in the year, a five-speed ZF gearbox became an option. The outboard fog lamps were now built into the front of the car.
The Series II also benefited from lighter construction materials; the heavy doors were repanelled in aluminium.
Available as both a coupe and a drophead, 1,073 TD21s were made between 1958 and 1963.
