Background
"The original and very successful TR2 formula reigned for eight years, but between 1961 and 1967 there was a complete redesign revolution." - Graham Robson, The Triumph TRs.
Introduced in 1961, the TR4 was the first bold step in the TR's transition from rugged, uncomplicated sports car to something altogether more refined.
Giovanni Michelotti's new bodyshell brought the styling bang up to date while beneath the skin there were numerous chassis changes.
The standard engine was the 2,138cc four-cylinder overhead-valve unit first offered on the TR3A.
The TR4 shared the same basic chassis as the previous TR3, but benefited from a wider front and rear track as well as rack and pinion steering.
The transmission offered full synchromesh in all forward gears and, when fitted with the optional Laycock de Normanville electrically operated overdrive, allowed the car to reach 60mph in about 10 seconds on its way to a top speed of 110mph.
Today, the four-cylinder TRs are among the easiest of post-war classic sports cars to own and maintain, supported as they are by a well-established network of component suppliers and other specialists.
The TR4 was upgraded in 1965 with independent rear suspension to create the TR4A, but many prefer the reliable simplicity of the 4’s live rear axle.
And everyone prefers solid, rust-free ex-Texas and California examples like this one.
