Triumph TR3

Contents

Contents

The TR2, built from 1953, turned into the TR3 in October 1955 without a break in the commission numbers: the last TR2 was TS8636 and the first TR3, by most accounts, TS8637. The new car kept the TR2's chassis, body and engine and added a new grille, bigger carburettors and more room behind the seats, where an occasional seat could be fitted at extra cost.

Its successor, the TR4, was announced in September 1961 with a full-width body by Giovanni Michelotti and wind-up windows. The TR3B was built beside it in 1962 for the North American dealers, who, the TR Drivers Club and Dwinger say, doubted the new car. How one car became the next is told on the history page.⁠source 3​source 2​source 16​source 6​source 17​source 18

In May 1957 Motor Sport visited three factories for one article and treated their sports cars as a set: the MG MGA, the TR3 and the Austin-Healey 100-Six. In the British price lists of 1955 and 1959 the TR3 cost more than the MGA and less than the big Healey. How they compared in price, power, numbers and results is on Rivals.

The press of the day kept coming back to its value and its toughness. Motor Sport's show report of November 1960 wrote of drivers "who want an almost unbreakable car which will stand up to terrific punishment". Bill Boddy put the value argument most plainly in the same magazine, looking back on the sports cars he had driven in 1957:

I regard this as THE finest value-for-money in the sports-car field and because it is such excellent value I can readily forgive certain minor crudities and failings.

The testers' verdicts, magazine by magazine, are on the road tests page.⁠source 1​source 2​source 19​source 20​source 21

  Works Triumph rally driver of 1958–59. With Alain Bertaut he won a Coupe des Alpes on the 1958 Alpine Rally in a works-prepared TR3, 1st in class and 4th overall and fastest up the Stelvio, and Shell's film of that rally follows his TR3 down the passes. In 1959 he won his class on the Tulip Rally and was 2nd overall "by only a few precious seconds", was 2nd in class and 8th overall on the Liège–Rome–Liège with Bertaut, and, in a Herald, drove in one of the two Triumph teams that took the first two manufacturers' team awards on the RAC Rally.

  Walter Belgrove

  Car stylist. According to the Standard Motor Club, he was born in Liverpool in 1900, was chief stylist of the pre-war Triumph company from 1934 and formed Standard's first styling department after the war. He drew the Standard Vanguard, the TRX and the 20TS, from which the TR2 was developed; in 1978 J. R. Davy credited him with the Renown, the Vanguard and the TR2. After a complete falling-out with the chief engineer, Ted Grinham, he resigned after the 1955 Motor Show, later took small commissions (among them bodywork for the Ferguson P99), retired to Devon and died in 1983.

  Managing director of the Standard Motor Company, later Standard-Triumph, from early 1954, when Motor Sport saw "young Alick Dick" set up "as head of the Standard empire" on Sir John Black's retirement, until Leyland's takeover in 1961. The TR3 and most TR3As were built under him. Michelotti's arrival is told two ways: Graham Robson says he was introduced through Raymond Flower and hired on Harry Webster's recommendation with Dick's approval; G. William Krause says the TR3 "Dream Car" followed a chance meeting between Dick and Michelotti at a motor show.

Kastner" winning two races in a TR2 at Cheyenne, Wyoming. In 1959, by the TSOA Newsletter's account, he won the Pacific Coast Class E Championship, the California Sports Car Club championship and the Motoracing West Coast Point Championship in a TR3 he drove to work and to races. After preparing three TR4s that finished 1st, 2nd and 4th in their class at Sebring in 1963 he set up Triumph's US competition department (by his account, no other foreign maker had one there) and wrote Triumph's competition preparation manuals. He finished three of the works TR4s for the 1964 Shell 4000, built the TR4A Super Stock in which Charlie Gates won the 1965 SCCA D Modified title, captained the TR4A team whose cars were 1st, 2nd and 3rd in class at Sebring in 1966, and in 1968 built the TR250K, a prototype on a TR4A chassis, with Peter Brock for Sebring. He was the factory team's guest at Le Mans in 1964 and owned the Macau Spitfire from 14 April 1966 to 2 February 1968. He left Triumph at the end of 1970 and was inducted into the British Sports Car Hall of Fame in its first class, 2017.

  Standard-Triumph engineer who worked on the TR3 Beta. His account, published by the TR Drivers Club in 2015, is the source of the view that "the TR3 BETA came first" and that the TR4 then used its chassis and running gear, and of the works' own name for the project, "TR3B".

• GM

  stylist

  Giovanni Michelotti

  Turin car stylist. He began his career in 1937 as an apprentice at Stabilimenti Farina; according to carrozzieri-italiani he opened his own design studio in Turin in 1949, the first in Italy devoted only to car design; the TSOA Newsletter of 1966 also dates the studio to 1949. His first contact with Standard-Triumph came in 1957: Harry Webster's obituary in the Telegraph says Webster "discovered" him, while Graham Robson says he was found through Raymond Flower and hired on Webster's recommendation with Alick Dick's approval. His first Triumph design was the one-off TR3 "Dream Car" on a TR3 chassis, shown at Geneva in 1957 according to later accounts; Krause says it followed a chance meeting with Alick Dick at a motor show. He went on to design the Italia (1959–62) on TR3A and TR3B running gear. On his own initiative he drew a one-off body for a BMW 507 chassis, shown at the Turin show in 1959, which BMW has owned since 2005. He styled the Herald (1959), whose separate chassis made the Spitfire possible; answering Webster's idea of a "Herald sports car", he built a single prototype in 1960, code-named "Bomb", and later restyled the car as the Mk IV of 1970. For the TR he styled the prototypes Zest (1958) and Zoom (1959) and the TR4 of 1961, which joined Zest's nose to Zoom's tail and kept Zoom's hardtop with its lift-out panel; the TR4A, TR5 and TR250 kept that body with new detail, and its centre section on the TR6 (1969), whose new front and rear Karmann designed because he was busy. According to his son Edgardo, his work for Triumph ended in the late 1970s with a restyle of the TR7 from coupé to spider; he died in January 1980. No source read links him to the Le Mans or Macau competition bodies.

He joined Standard-Triumph in 1952 after driving the 20TS prototype, which he reputedly condemned as unsafe; he tested and developed the TR2, drove it at Jabbeke in May 1953, and from 1954 ran the new works competition department. Through the TR3 years he managed the works team: five Coupes des Alpes and the team prize on the 1956 Alpine Rally, where his own car retired after losing a rear wheel, and the three TR3S twin-cams at Le Mans in 1959. A Moss Motoring profile says he left for TVR in 1962, unhappy with the Leyland takeover.

In 1968 he raced Group 44's TR250 in SCCA C Production. By the importer's count in September he had six wins in the Northeast Division, enough for at least a tie for its title, and three outside it. He was 3rd in C Production at the ARRC, and he co-drove the TR250K at Sebring. From 1969 to 1974 he raced Group 44's TR-6 in SCCA C Production, 2nd at the 1972 American Road Race of Champions, and showed it on British Leyland's stand at the 1972 London Motor Show; Severson writes that the last TR6 built went to him.

  Harry Webster

  Standard-Triumph's engineering chief: director of engineering from 1957 (Graham Robson says 1956) to 1968. The TR Register names him as chief chassis engineer of the team that engineered the TR2. The Spitfire was his idea of a "Herald sports car"; he brought Giovanni Michelotti into Standard-Triumph's work in 1957, Graham Robson credits his "persuasive powers" with Leyland's approval of the 1960 prototype after Standard's financial collapse, and took Triumph back to Le Mans with Spitfires, which won the 1.15-litre GT class in 1965. After British Leyland was formed he moved to Longbridge; CBE in 1974. He died at Kenilworth, aged 89.
