1962 Triumph TR4 Roadster

The coachwork is what first distinguishes the TR4. By the late 1950s, the idea of an open cockpit, low door, side-curtained roadster was seen as outdated. In response, Triumph management moved to an open-cockpit sports car with roll-up windows. The ventilation and heater system also needed updating and the cockpit interior and luggage space needed further enhancements. With these basic parameters in mind, the Italian designer Michelotti came up with a wider, lower, and more finely finished body.

The engine used was a larger 2138cc Standard engine with 86mm pistons in 'wet liners.' The horsepower rating is 105bhp with 128 foot-pounds of torque. Road and Track magazine reported in 1962 that the TR4 would go from zero-to-sixty mph in 10.1 seconds with a standing quarter-mile time of 17.5 seconds at 77.2mph.
