The Triumph TR5 was built for a 15 month period between 1968 and 1969 by the Triumph Motor Company in the United Kingdom, during which time approximately 2,947^[1] cars were built.

The TR5 looked remarkably similar to the TR4A which preceded it. The main differences were under the body, and the most significant of these was the engine. The TR5 boasted a 2.5 litre straight 6 fuel injected engine developing around 150 bhp (110 kW). This engine was carried forward to the TR6.

At the time, fuel injection (or petrol injection as it was sometimes called back then) was uncommon in road cars. So much so that Triumph claimed in their sales brochure that it was the "First British production sports car with petrol injection".

This engine could propel the TR5 from 0 to 60 mph in just 8.1 seconds, and on to a top speed of 125 mph (201 km/h).

The TR5 came equipped with front disc brakes, independent rear suspension, rack and pinion steering and a four speed gearbox. The available optional extras included overdrive, wire wheels and a hard top with detachable roof panel.

In 1968, the TR5 sold in the United Kingdom for approximately £1,260, with wire wheels being another £38, overdrive £60 and a tonneau cover another £13.^[2]

The TR5 was virtually identical to the TR250, built during the same period for the North American market. Because of price pressures and emission regulations the TR250 was fitted with twin Zenith-Stromberg carburettors rather than the Lucas fuel injection system, and took 10.6 seconds to get to 60 mph (97 km/h).
