Produced between 1961 and 1967, the Triumph TR4 combined a new, modern, and aggressive body design by famed Italian stylist, Giovanni Michelotti, with the basic chassis of the previous TR3A. The TR4 also improved passenger comfort with wind-up windows, face-level ventilation, and an optional hardtop. When equipped with the optional overdrive, the TR4 was good for a top speed of almost 110mph. Following on from the TR4, the new TR4A was phased in smoothly at the beginning of 1965 and introduced an all-new independent rear suspension system (IRS), which provided exceptional rear-wheel camber control with excellent wheel travel while softer springs improved the ride quality. Having six universal joints, three prop shafts and two trailing arms, the system was appreciatively more expensive than the previous live axle arrangement (dealers in the US reacted uncomfortably to the new design on cost grounds; to appease them. The press was happy to see an all-independent car, and Triumph was pleased to be the first British car manufacturer to have all-independent suspensions under every car in their line-up. At the Sebring 12 Hours in 1966, ample proof of the validity of the IRS was provided when three IRS-equipped TR4As achieved a remarkable 1-2-3 class victory. Body production changes for the TR4A were a new grille, decoration and badging, and a radically different chassis (designed to accept the new semi-trailing arm independent rear suspension), plus the introduction of an up-rated version of the 2138cc Vanguard 4 cyl motor unit, now with a new decoration, badging, sidelights and chrome trim along the door/wings, a wooden dash, better cylinder head breathing through a new exhaust. …….
