Giovanni Michelotti and the Triumph TR4

The Turin stylist who drew Standard-Triumph's Dream Car, the Zest and Zoom prototypes and the TR4 that combined them, and whose body carried on, retouched, through the TR4A, the TR5 and the TR250.

Michelotti, who designed the Herald bodies, also styled the TR-4 — back in 1959. He did so, we were told at Standard-Triumph's Coventry factory, in half an hour flat, which suggests this is a branch of art in which first thoughts can be best.

Dennis May, Car and Driver, October 1961

It was a good story, and it was the factory's. The sources that trace the TR4's design describe something slower: two prototypes over two years, Zest and Zoom, both drawn by Giovanni Michelotti, and a final shape that blended them, which Ate Up With Motor dates to late 1960. Michelotti was by then a Turin stylist with a studio of his own, which the American importer's owners' newsletter dated to 1949.⁠1​2​3

His arrival at Standard-Triumph in 1957 has four explanations: through a customer, Raymond Flower, by the German TR Register's account and Graham Robson's; through a businessman from outside the company, in Ate Up With Motor's; after a chance meeting with Alick Dick at a motor show, in G. William Krause's; and by Harry Webster's discovery, in Webster's obituary in the Daily Telegraph. His first commission, the German guide says, cost Standard-Triumph £3,000 and was ready in three months, built on a TR3 chassis shipped to Italy.

The result was the "Dream Car", a TR3 that Vignale rebodied for the Geneva show of March 1957, whose full-width grille, Krause writes, the TR3A took up. The Herald saloon (sedan), launched in 1959, became the first of his designs that Standard-Triumph built in numbers. For the TR3's successor he drew Zest, finished early in 1958 on a TR3A chassis, and Zoom, a pair that Vignale built in 1959 on a longer, wider frame, one of them with a hardtop in two parts. Alongside them he drew a coupé on the TR3's chassis, the Italia, which Vignale built for Salvatore Ruffino.

In 1960, with Standard-Triumph short of money, he was asked for a car between the two. Ate Up With Motor's account of his answer is brief: "With customary alacrity, Michelotti returned with a tidy amalgam of the two previous designs." The TR4's nose came from Zest, and its rear wings (fenders), tail and two-piece hardtop from Zoom.

His body outlived the car: the TR4A wore it with a new grille and trim, and the TR5 and TR250 of 1967 used it again, in what the Rimmer catalogue's summary calls a "re-touched TR4A style". Only for the TR6 did Triumph go to Karmann for new front and rear ends, Revington TR says because of "Michelotti being busy", and even then the centre of his body stayed.⁠26​8​5​11​2​12​27​18

What he brought to the TR

The TR4 took from the prototypes what the TR3 had lacked: wind-up windows and a fixed, curved windscreen (windshield). Michelotti gave it a full-width bonnet and grille that, in Krause's words, "beautifully disguised the crudeness of the manufacturing methods", and Revington TR writes that Standard-Triumph's managers were impressed that "the demands of mass-production had been considered". Where Zest had scoops, he gave the bonnet a single off-centre bulge over the carburettors, which kept it low, and Car and Driver noted the deep swage lines over the wheel arches and along the sills (rocker panels) that kept the wider car from looking squat. The hardtop with its lift-out roof, first seen on Zoom, became an option on the TR4.

The importer's newsletter, introducing him to its readers in 1966, wrote that since the Herald "Michelotti's distinctive 'M' has been applied to all new Triumph models". It was a figure of speech: no source read shows an M on any Triumph. But the shape of the TR4 ran, in one form or another, from its launch in 1961 into the TR6.⁠11​1​2​28​3

Roles

  1. 1958

    Stylist

    1958–1961. Styled Zest (early 1958) and Zoom (1959), the TR3's successor prototypes, and the TR4 that joined Zest's nose to Zoom's rear wings and tail; Zoom's two-piece hardtop with a lift-out panel became the TR4's. Car and Driver was told at Coventry in 1961 that he had styled the TR4 in 1959, in half an hour; Ate Up With Motor places the final blend of the two designs late in 1960

  2. 1965
