Triumph TR4 / TR4A

The Triumph TR4 was introduced in September 1961 to replace the TR3. It used a modified TR3A chassis and the 2138cc 4 cylinder engine that was previously available on the TR3A as an option. The bodywork however was completely new, having been designed by the Italian stylist Michelotti. This was the first TR to have wind-up windows and also included other benefits over its predecessors, such as face level ventilation in the dashboard and a larger boot compartment. A hardtop was available as an optional extra. The TR4A arrived in 1965 with a redesigned chassis that featured a new independent rear suspension arrangement to give the car a more comfortable ride. The TR4A also underwent some minor styling changes and a small increase in engine power to overcome the disadvantage of being slightly heavier than the TR4. A combined total of over 64000 TR4/4A models were built before production ended in August 1967. It was replaced by the TR5.
