Produced between 1961 and 1964, the Triumph TR4 combined a new, modern and aggressive body design by famed Italian stylist Giovanni Michelotti with the basic chassis of the prior TR3A. The TR4 also improved passenger comfort with wind-up windows, face-level ventilation, and an optional hardtop. The 2,138 cc engine of the late-production TR3A continued, while the 1,991 cc engine was also made available to buyers who participated in two-liter racing classes.
The TR4A debuted for 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 ride quality. Some 28,465 TR4A roadsters were produced between 1965 and August 1967, and of those, 75 percent were equipped with the new IRS, including the car offered here. 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.
This car was auctioned off by RM Auctions in January of 2011 at the Arizona Biltmore Resort & Spa, Phoenix, Arizona.
