The Triumph TR4
Lacking a sports car capable of competing with those of MG and Jaguar, Triumph started developing a new sports car, the TR2, which it displayed proudly at the Geneva Motor Show in March 1953. An enormous success both at home and abroad, it was to be expected that its successor - the TR3 - would represent evolution rather than revolution. Introduced in October 1955, the TR3 was, indeed, little different from the preceding TR2. Changes to the 2.0-liter engine boosted power from 90 to 95bhp, but the most obvious difference was the adoption of an 'egg box' radiator grille. The engine developed 100bhp courtesy of a new cylinder head by mid-1956; then in August, Girling front disc brakes were introduced. The TR3A was introduced during 1957, with cosmetic changes including new front-end styling featuring a full-width grille incorporating sidelights/indicators, and locking door and trunk handles plus an improved interior.
The first step in the TR's transition from uncomplicated, rugged sports car to something altogether more refined, the TR4 was introduced in 1961. Giovanni Michelotti's new body shell brought the styling up to date while beneath the skin there numerous changes to the chassis. Rack-and-pinion steering, widened front and rear track, and an all-synchromesh gearbox contributed to improved drivability, while wind-up windows were a big advance on the TR3s primitive side screens.
The standard engine was the 2,138cc four-cylinder overhead-valve unit first offered on the TR3A, and when equipped with the optional overdrive the TR4 was good for a top speed of almost 110mph. Today, the four-cylinder TRs are among the easiest of post-war classic sports cars to own and maintain, being supported by a multitude of component suppliers and other specialists. A rare factory option was the hardtop known as the "Surrey Top", an early attempt at a Targa. The hardtop featured a removable center panel, giving any TR4 so equipped a versatility that was unique at the time.
Today these charismatic "surrey top" Triumph sports cars remain popular for their usability, ease of maintenance, good looks and the fact that they are immense fun to drive.
The Motorcar Offered
The British Motor Heritage Trust Certificate for this Triumph confirms it was completed on June 14, 1962 and originally painted black with contrasting red leather trim. Delivered to the Standard Triumph Motor Company of Boston, Massachusetts, this early TR4 was one of the first 500 built and underwent an exhaustive multi-year restoration by Precision Autocraft of Massachusetts in the mid-1990s. The wonderful condition of the car today is testimony to the quality of the restorer's workmanship. The seats were upholstered in high quality leather trimmed in the original color and a period Nardi wood-rim steering wheel fitted. The appearance was further enhanced with a set of chrome wire wheels, while the engine bay was beautifully detailed.
Post-restoration, the Triumph enjoyed a successful career on the Concours circuit, consistently winning its class or Best in Show awards before being retired in 1997. It was featured on the cover of The Vintage Triumph magazine following its 1st place at the 1994 Vintage Triumph Register National Concours. The TR4 joined the Wayne Oldenburg Collection in the late 2000s, and remained in that prominent collection until its acquisition by the consignor in 2013. Presented in nicely mellowed condition with a lovely patina, this car is perfect for tours or rallies and with minimal cosmetic refreshing could make a triumphal return to the show circuit.
