Triumph TR3B Roadster

Heavily influenced by the prototype TR, the Triumph TR2 debuted in late 1953 and quickly gained renown for its reliability, superior gas mileage and commendable performance. In fact, thanks to a price tag lower than the Austin-Healey and several race victories including the 1954 RAC Rally, the car soon became a favorite with the motoring public, who endured long waiting lists to acquire their own.

Introduced at the 1955 London Motor Show, the TR3 benefited from such external changes as a new grille and stainless-steel fender beading. A back seat for children was also made available, as was an overdrive option on the four-speed transmission. Under the hood, a pair of enlarged 1.75-inch SU carburetors was added, helping to boost output to 100 brake horsepower. On the interior, a cowl vent and sliding panels within the side curtains improved comfort.

In 1962, the TR4 was introduced. The U.S. distributor for Triumph was a little skeptical about how it would be received in North America and requested that Triumph carry the TR3 for one more year. Called the TR3B, the first of these cars were identical to the TR3A, which had been in production since 1958, while the later examples were fitted with the larger 2.1-liter engine and all-synchromesh gearbox, as found in the TR4.

This car was auctioned off by RM Auctions in August 2009 at the Shotwell Gustafson Pavilion at Meadow Brook Hall, Rochester, Michigan and in August 2009 at the Portola Hotel & Spa and Monterey Conference Center, Monterey, California.
