Triumph TR4 / TR4A Buyers Guide

The first big change, and the first Leyland TR. Mechanically based on the TR3A, but with modified chassis, and rack and pinion steering. 100bhp/2138cc standard: all were given an all synchromesh gearbox. Michelotti produced a brand new body style, those shells being built at Speke, Liverpool: including wind up windows, and face level ventilation. More space in the cabin and better steering, but no more performance. 40253 cars built, from 1961 to 1965.

A straightforward evolution of the TR4, the TR4A had a completely new all independent chassis frame under the same basic body shell. Coil springs / semi trailing arms at the rear made this the softest-riding TR so far. All cars had 104bhp/2138cc. As with the TR3B, North American dealers demanded a cheaper alternative. Only for that continent there was a live rear axle version of the new chassis frame; not please note the old TR4 frame. 28465 card built from 1965 to 1967.
