The wedge-shaped TR7 with Rover's aluminium V8, power steering and a stronger driveline, built from 1977 to 1981 and sold almost only in the United States and Canada, nearly all as convertibles. With the TR7, it was the last of the TRs.

The V8 was meant to be there from the start. The TR Drivers Club and Mike Cook, Jaguar Rover Triumph's man for the American press in those years and later the car's historian, agree that the wedge-shaped sports car code-named Bullet was planned with two engines, a four and Rover's aluminium V8. The four came first, in the TR7 of 1975. Cook explains why the V8 waited: the Stag's engine was not to stay in production, Rover's was in short supply, and no five-speed gearbox (transmission) of the time was strong enough for it.
In 1977 a first run of V8 coupés was built at Speke, in Liverpool, for an American launch the following year. BL postponed the launch indefinitely, and most of the cars crossed the Atlantic without a single badge, as company cars for its own staff in the United States and Canada. BL's works rally team ran its V8 cars as TR7 V8s, on the Group 4 recognition the FIA gave the TR8 on 1 April 1978. The TR8 raced before it went on sale, too: in July 1979 Bob Tullius's Group 44 won its class with one at its first race, the Watkins Glen 6 Hours, finishing 7th overall.
The TR8 reached American showrooms in the spring of 1980 (in May, by Michael Lamm's account), as a convertible. In 49 states it ran on two carburettors and in California on Lucas/Bosch fuel injection, which every North American car of the 1981 model year had. The magazines were delighted: Car and Driver thought it had reinvented the sports car, and Road Test chose it as the best new sports car of the year, as the road tests tell. On the track, TR8s won the GTO class of IMSA's series five times in 1980, Tullius in four of them.
The showrooms were harder: after the Iranian revolution petrol (gas) was dear, the American economy weak and the pound high against the dollar. By the end of 1980 Jaguar Rover Triumph was offering a $1,000 rebate on the TR8. A right-hand-drive TR8 for Britain got as far as a pilot run before it was dropped, early in 1981 by the product planner's account. In May 1981 BL announced that the TR7 and TR8 would end; most of the British cars and the factory's development fleet were sold at BCA's auctions at Measham in August and September, and the last TR8s were built at Solihull in October.
With better timing, the TR8 might have saved a company. Instead, it faded away before the world could discover how good it really was.
How many were built depends on who is counting. BL's own calendar-year table leaves out the pre-production cars, and identification sets every count beside its source.source 1source 2source 3source 4source 5source 6source 7source 8source 9source 10source 11source 12source 13source 14

The TR8's place in the line was taken before it arrived. The TR7 had been on sale in America since April 1975, and the last TR6 left Canley in July 1976, long before any TR8 reached a showroom. The TR8 was a TR7 with Rover's V8, not a new design: the history tells how the two were planned together, and why the V8 came so late. It took its engine, five-speed gearbox and axle from Rover's SD1 3500 saloon (sedan).
Nothing followed it. Two longer cars on its underpinnings, the Lynx and the Broadside, never reached production, and the TR7 and TR8 of 1981 were the last of the TRs. The Triumph name lasted until 1984, on the Acclaim, a car based on a Honda.
To a large extent, the TR8 fulfills the promise of the TR7 and is more in keeping with what the car was originally supposed to be.
The history's rivals section sets it beside the four cars the American press compared it with, from the Mazda RX-7 to the Porsche 924, on price and pace. The changes made for each market, from California's injection to the British cars' carburettors, are on the versions page.source 15source 2source 16source 6source 17source 11source 18source 7source 5source 19

Not every V8 wedge is a TR8. "TR7 V8" was the name BL's works rally cars ran under and, triumphtr8.com says, the one some of the first coupés wore, and it is the usual name for the many TR7s that owners and specialists have since given V8 engines, some of them with TR8 badges added. Identification explains the numbers, TR7 V8 conversions the converted cars, and the buyers guide what to look at before buying one.
Whatever the badges say, only the chassis number settles it, with the engine number and a Heritage Certificate from the British Motor Museum's archive behind it.source 12source 2source 3source 20source 21source 22

chief engineer, technical director
British engineer (1925–2010). He joined Rover in 1945 and became its chief engineer in 1959; the Range Rover (1970) is his best-known car, and he also engineered the Rover SD1. After the 1968 merger he succeeded Harry Webster as Triumph's technical director and led the TR7's engineering. AROnline credits him with developing the 16-valve head; Ate Up With Motor credits it to Lewis Dawtrey.

stylist
British car stylist: British Leyland's chief designer in the 1970s and early 1980s, best known for the Allegro, the Princess and the TR7. Trained at engineering school and as an apprentice at the coach and bus builder Duple, he worked with Roy Haynes on the Marina and styled the wedge-shaped Austin Zanda show car (1969). His Longbridge team's wedge became the TR7: he said he went to the United States before drawing it, which made the design more extreme, and that it was meant to have a targa roof, which engineering could not make work. The convertible's prototype was Michelotti's, not his. He died in 2023, aged 85.
Racing driver for Group 44. In 1975, as British Leyland's Triumph team driver, he won the Northeast Division and then the SCCA D Production national championship in Group 44's TR6, at Road Atlanta on 2 November, leading from flag to flag; that September he finished 3rd overall in the Brainerd Trans-Am in the same car. He shared Group 44's TR8 with Bob Tullius and John Kelly in the 1980 Daytona 24 Hours (racingsportscars).
stylist
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.
SCCA national champion in a Spitfire (F Production, 1969) and in a TR7 (D Production, 1979). In 1974–75 he drove Huffaker Engineering's V12 E-Type in SCCA B Production, winning on its debut at Seattle in August 1974.
project manager
Managed the right-hand-drive TR8 project of 1980–81 at Canley and Solihull; he later wrote about it in Practical Classics (September 1997).
American racing driver. He won the SCCA C Production national championship at the 1981 Runoffs at Road Atlanta in "a highly modified TR8", in Mike Cook's words.
founder
American racing driver. He bought a TR3 in 1960 and raced from 1961. In TR4s he won the SCCA national E Production championship in 1962, Triumph's first national class title by the importer's account, and D Production in 1963 and 1964; Triumph gave him one of Kas Kastner's Sebring TR4s. With Brian Fuerstenau and Dick Gilmartin he founded Group 44 Inc. in 1965; it won 14 SCCA national titles and three Trans-Am championships before closing in 1990. 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. In 1974–75 he raced Group 44's V12 E-Type in SCCA B Production: 2nd at the 1974 Runoffs by 0.8 s, and national champion in 1975. He had won the SCCA Trans-Am drivers' championship in 1977 and 1978 with a Jaguar XJ-S. From 1979 to 1981 Group 44, Jaguar Rover Triumph's official US racing team, raced the TR8 in IMSA and the Trans-Am. It won its class on the car's debut, the Watkins Glen 6 Hours of July 1979; Tullius won his class four times in 1979, in IMSA GTO and the Trans-Am, as Car and Driver and Lamm count them, and Group 44's No. 44 won the IMSA GTO class four times in 1980. British Sports Car Hall of Fame, first class (2017).
