Michelotti Zest – Triumph TR4

Project Zest was the code name for the Triumph TR4 which was launched in 1961.

It turns out that the TR4 gave Giovanni Michelloti a second crack at updating the Triumph TR3A having designed the body for the Italia 2000 GT, which was built on a Triumph TR3A knock down kit, first seen in 1959.

Michelotti’s new design did away with the window curtain’s of previous TR’s replacing them with proper glass window’s operated by proper window mechanisms, it was also one of the earliest cars to have a removable roof panel, predating the Porsche 911/912 Targa Top by five years.

Mechanically new for the TR4 was synchromesh on all gears, with a Laycock overdrive on 2nd, 3rd and 4th gears and the steering was altered to accommodate a rack and pinion.

Two engine options were available for the TR4 one just under 2 litres / 122 cui and the other just over.

TR4’s found competition success in the USA where Bob Tullis drove a Kas Kastner prepared example to class victory at Sebring in 1961 and SCCA class championships followed in 1962, ’63 and ’64.

This particular TR4 was part of the works rally team and was driven to a 4th place overall finish in the 1962 Alpine Rally by Mike Sutcliffe and Roy Fidler.

Sadly of the over 40,000 TR4’s built between 1961 and 1965 less than 1,000 are still registered with British Authorities.
