Background
Visually almost identical to its predecessor the TR4, Triumph’s Michelotti styled TR4 was only produced for 13 months – between August 1967 and September 1968. But what the Five hid under the familiar bonnet that the Four didn’t have was the new 150 bhp fuel-injected 2.5litre straight-six engine, giving the new model a 0-60mph time of around 7.5 seconds and a top speed of 125mph.
Disc brakes up front and independent rear suspension, as well as rack and pinion steering helped exploit the new found performance.
Although largely produced as a rag-top roadster, some cars left the factory with the so-called 'Surrey Top', a steel roof that included a detachable centre panel, giving more substantial protection with the option of open-air motoring when desired.
