The Triumph TR4 is the fourth in a series of eight TR models. 'TR' stands for 'Triumph Roadster', and it can be said that roadsters dominated the production of British cars for a considerable period of time, it even became a trademark for British brands.

The TR4 is an easily recognisable British roadster. Its appearance and looks are of Giovanni Michelotti’s hand, who is an Italian designer whose portfolio had already been enriched by brands such as Ferrari, BMW, DAF. From the second half of the fifties, he even become Triumph’s single designer. The car is - as its predecessors are - based on its predecessors, yet the Italian touch could not be left out, which causes an eye-catching eclectic design. The lines are wavy and sporty, the headlights are very Italian, and the overall car is rather small, making it compatible with busy British city traffic. A luggage rack is mounted on the trunk, evoking a nostalgic atmosphere, and the so called ‘surrey top’ has a rear window is the precursor to the Targa that would later be claimed by Porsche. The interior is meticulously finished with leather seats that welcome the passengers on long and comfortable rides. The beautifully varnished wooden dashboard affirms modest British prestige and presents a lot of neatly finished gauges.

The roadster’s four-cylinder inline engine is fed by an S.U. carburettor for which the hood is made sportier representing a hood scoop. From 1965, two S.U. carburettors supplied the four-cylinder, which provided higher power. The engine is controlled by a four-speed manual gearbox and produces 100 or 104 hp and 203 or 206 Nm. Those statistics make it a rather sporty whole, considered the lightweight of barely 1,000 kg (2,240 lbs). The charming and modest sporty engine fits the eclectic glove perfectly.

New TR series models were always based on their predecessors, the TR4 was no exception. The TR4 was officially built from 1961 to 1967. In 1965, improvements were made and the TR4 provided better and more modern handling. Independent suspension replaced the rigid rear axle, to make this possible Triumph revised the chassis shape. A distinction is made between before and after 1965 models, models before 1965 are regularly named TR4, later models are named TR4A or TR4 IRS.

Triumph TR4A

The TR4A is the upgraded after 1965 of the Triumph TR4 that was built until 1967. From 1965 on, the rear-wheel suspension became also independent, the Americans even named it TR4 IRS, IRS representing Independent Rear Suspension. Additionally, the engine was supplied by two carburettors instead of just a single one, which impacted both power and torque.

A total of approximately 30,000 TR4A's were built. The TR4A remains a fun classic car that sparks desire among aficionados. Also, selling trends make believe that a TR4 is a good investment.
