The Triumph TR4 is a sports car produced by Triumph from 1961 to 1965 as the successor to the TR3A. It was sold as a 2-door coupe with rear-wheel drive, a front-mounted engine and the option of a retractable roof. The chassis and drivetrain of the car has been updated, but still very similar to its predecessor. A total of 40 253 examples were produced. The car was basically powered by a 2.1-liter I4 engine with 100 hp (74 kW), which was mated to a 4-speed manual transmission. The TR4 was able to reach a speed of 166 km/h.
In 1965, the TR4 was replaced by the TR4A. Although almost identical, it had a more refined chassis with independent rear suspension and significant changes to the interior.
