History Car 1960s

Triumph TR4

Overview

Launched in 1961, the Triumph TR4 was a major evolution of the British sports car formula. Designed by Giovanni Michelotti, it combined striking bodywork with robust mechanicals, including a 2.1L engine and advanced (for the time) handling features. With its torque-rich motor, precise rack-and-pinion steering, and rally-tuned suspension options, the TR4 earned respect as both a competitive stage car and a roadgoing performance icon throughout the 1960s.
