The Triumph TR series of sports cars really began life when the chairman of Standard-Triumph, Sir John Black, decided the company needed a sports car to compete with the iconic Morgan. However, Sir John also wanted to build the car using parts already being produced by the company, especially expensive to create parts such as the chassis, suspension and engine. In effect Sir John wanted a sports car, but at minimal cost and minimal effort. The resulting Triumph TR1, better known as the 20TS was not a success, but out of its failure the ideas were germinated to create a new sports car built on a new frame with revised suspension and brakes, and an uprated engine. This car was the TR2 of 1953 and it formed the foundation for all the TR series cars up to and including the TR6.

The TR6 was the last development of the series of cars that began in 1961 with the new body style designed by Giovanni Michelotti for the TR4. The TR4 and later cars were still built on the same basic framework as the original TR2 but the TR4 saw a major change in 1965 when the live axle rear suspension was replaced with a new independent rear suspension with trailing arms, creating the TR4A. The car was developed further in 1967 with the installation of a 2.5 liter in-line six cylinder engine based on the engine used in the Triumph 2000 sedan, and with the fitting of servo assistance to the front disc and rear drum braking system. This new car was sold in Britain and Europe as the Triumph TR5 and in the United States as the TR250.

Just one year later in 1968 Triumph unveiled the TR6, the principle difference in this car being the modernization of its body style. The re-vamped body was remodeled by German design house Karmann and gave the TR6 the clean aesthetic lines that would set it apart and make it into the classic British sports car it deserved to be. The TR6 would remain in production until 1976 and would become one of the more sought after British sports cars of the twentieth century.

Engine: 2,498cc in-line six cylinder OHV.

Power: Lucas fuel injected early model 150bhp. Later the fuel injected engine was de-tuned to produce 125bhp “to make it easier to drive”. US market carburettor model 104hp.

Transmission: Four speed all synchromesh manual gearbox with Laycock de Normaville electric overdrive option. The Laycock de Normanville overdrive was originally fitted to the 150bhp cars with overdrive available on 2nd, 3rd, and 4th gears but service failures led to later models having the overdrive available on 3rd and 4th gears only. (Note: This may have been one of the contributing factors to the decision to reduce the engine power of the Lucas fuel injected models.)

Suspension: Front independent with unequal length wishbones and coil springs; rear independent with trailing arms.

Brakes: Front discs, rear drums. Servo assisted.

Chassis and body: Separate chassis made of 16swg steel box section with inner strengthening baffles, spot welded. Body shell bolted to the chassis.
