Produced between August 1961 and January 1965 with about 40,250 built, the TR4 signaled the end of one era and the beginning of a new one for Triumph. While purists howled, everyone else rejoiced. Representing evolution rather than revolution, the TR4 retained the sound basic chassis design of the outgoing TR3A, combined with completely modern and aggressive bodywork designed by Italy’s Giovanni Michelotti. The TR4 incorporated a proper trunk compartment, a TR-series first, and passenger comfort was greatly enhanced with the addition of wind-up windows, improved cockpit ventilation and the availability of an optional hardtop. Driving dynamics improved as well, with precise rack-and-pinion steering and a synchromesh first gear.
The 2,138-cc OHV inline four-cylinder engine of the late-production TR3A was utilized, while the somewhat smaller-capacity 1,991-cc unit was also available for buyers who participated in sanctioned two-liter racing classes. Like its successful forebears, the TR4 proved devastatingly effective on the racing circuit. American racing driver Bob Tullius, of Group 44 fame, won his first SCCA E-Production road-racing championship at the wheel of a new Triumph TR4.
This car was auctioned off by RM Auctions in August of 2011 at the Portola Hotel & Spa and Monterey Conference Center, Monterey, California and in October of 2011 at the Battersea Evolution, London.
