Triumph TR8 History

From the V8 Bullet prototypes of 1973 to the last cars built at Solihull in October 1981: why the V8 came years after the TR7, how a postponed launch sent a run of unbadged coupés to America as company cars, and why the convertible, on sale from 1980, sold slowly.

On 1 April 1978 the FIA recognised the Triumph TR8 for Group 4. Apart from prototypes, the only TR8s yet built were a run of coupés made at Speke the year before, most of them by then in North America as company cars without a badge on them, and BL had postponed their launch indefinitely. Nobody could buy a new TR8 for another two years.⁠1​2​3​4

Before and after

The TR8 belongs to the family it was planned with. Mike Cook, Jaguar Rover Triumph's public relations manager in America when the TR8 was launched, writes that BL's sports-car policy of 1971, project Bullet, was meant to replace both the TR6 and the MGB. The four-cylinder TR7 was its first car, on sale in America from 1975, and for a while it was sold beside the TR6 it was to replace: Motor Sport reported in February 1975 that it would be sold "alongside the TR6 in USA British Leyland showrooms". The last TR6 was built at Canley in July 1976.

The TR8 came from the same body, and from Rover it took the SD1 3500's V8, its five-speed gearbox (transmission) and its axle; Road & Track noted in 1979 that the SD1 had been named European Car of the Year in 1977. BL's earlier Rover-engined sports car, the MGB GT V8 of 1973–76, had never been sent to America. Road & Track reached further back for a precedent:

The TR8 concept is bound to stir memories of the Sunbeam Tiger of the Sixties, but the Triumph is a much more civilized car with braking, steering and handling characteristics designed to mate with the V-8 engine's performance capabilities.

Thos L. Bryant, Road & Track, 1979

Nothing followed the TR8. The Lynx, a longer 2+2 on the same underpinnings, and the Broadside, planned for 1983 with a longer wheelbase and a V8 or an O-series four, never reached production, and neither did the MG Boxer, an MG-badged TR7; their story belongs to the TR7. Cook counts the TR7 and TR8 of 1981 as the last TRs. The last car of any kind to wear the Triumph name was the Acclaim, based on a Honda, which ended in June 1984; its successor was badged as a Rover.⁠2​5​6​7​8​9​10​11​12​13

Bullet and the V8, 1969–77

The TR Drivers Club dates the wedge to 1969 at Canley, under the code name Bullet, with two engines in view: Triumph's two-litre slant four and Rover's aluminium V8. Cook dates the policy behind it to 1971, when Triumph's own design for an open two-seater lost to the wedge offered by the Austin-Morris studio under Harris Mann. Either way the V8 was in it from the beginning: "From the start, four-cylinder and eight-cylinder models were developed in parallel," Cook writes.

It began as a coupé because America seemed about to outlaw open cars. Road & Track recalled in 1979 that "it seemed that U.S. lawmakers were going to ban convertibles", and by late 1973, when a federal court overruled the proposed rules on roof strength, the closed car was too far along to change.

The TR Drivers Club lists four V8 prototypes of the TR7 family: X840, X843, X858 and X859, the first two registered TLB 254M and UXC 582M. According to triumphtr8.com, X840 was registered in August 1973 and first ran with Bosch fuel injection, later swapped for carburettors, and X843 followed in May 1974. Wikipedia, citing William Kimberley's guide of 1981, dates a first V8 prototype to 1972.

Then the V8 waited. Cook gives three reasons: the Stag's own three-litre V8 had not been approved for further production, the supply of Rover's engine was "severely limited by Rover's production capacity and future model program", and there was no five-speed gearbox strong enough for it. So the TR7 went first. It was shown to the American press at the end of January 1975 and reached the showrooms that April, and by 1976, the TR Drivers Club says, American dealers were asking for the V8.⁠7​2​9​14​15​16

The Speke coupés and homologation, 1977–78

Speke, in Liverpool, made the first TR8s from February to October 1977: coupés to American specification, numbered with an ACN prefix and meant to go on sale as 1978 models. British Leyland's American company had their sales brochure printed that September. The launch never came. Cook writes that poor build quality at Speke, the plant's coming closure and doubts over how fast production could start in Coventry led BL to postpone it indefinitely. What became of the coupés, and how many there were, is on the coupé's page.

The TR8's FIA recognition for Group 4, number 654, followed in April 1978.

Speke did not last the year. Production of American-specification TR7s there ended in May 1978, the TR Drivers Club says because of labour problems, and moved to Canley, where assembly began that October.

Canley: coupés and the first convertibles, 1978–80

At Canley the coupé went on under the TCN prefix, though most of the numbers set aside for it in the 1978 and 1979 model years were probably never used, in the TR Drivers Club's view. The convertible followed. About 10 prototype convertibles were built at Speke in April and May 1978 and given V8s at Canley late that year; Canley's own TR8 convertibles came next, for the 1979 model year, in numbers no source read gives.

Early in 1979 Thos L. Bryant of Road & Track drove the "only U.S.-specification TR8 available", near Donington, with Jacques Duval. He found it "quick, responsive and fun to drive", and Jaguar Rover Triumph then planned to put the TR8 on sale "in July", with a TR8 convertible to follow in America "by October or November". Autocar's John Miles fared worse in 1979 (in May, according to triumphtr8.com) with YDU 617S, a white left-hand-drive engineering coupé collected from Browns Lane; the road tests tell what he found. From October 1979 Canley's cars carried a new 14-character vehicle identification number, which identification decodes.

On the track the TR8 was already winning: Group 44, Bob Tullius's team, began racing one in July 1979 and won its class at once.⁠17​4​9​10​19​20​2

The US launch, 1980

Mike Cook organised the press launch:

As Public Relations Manager for Jaguar Rover Triumph, I had booked hotels for 1978 and 1979 press introductions in Tucson and Monterey but had to cancel both. We finally did the deed at the Hotel del Coronado in San Diego, in March of 1980.

Michael L. Cook, Special Interest Autos, November–December 1996

Michael Lamm, recalling the San Diego drive in 1999, put it a year earlier; the road tests explain why March 1980 is right. The cars reached the dealers that spring: Lamm gives May, and AROnline gives May in one place and June in another. In Canada the TR8 arrived early in 1980, beside the Rover 3500.

The convertible came with two engines. California's cars of the 1980 model year were injected, under the certificate the state's Air Resources Board signed on 18 March 1980, and the other 49 states' had carburettors. Road & Track's June issue warned that "only 2500 TR8s will be built before the 1980 model year is out", so buyers should get in line. They did not. Within months the price was being cut, with a $1,000 rebate by the end of 1980 in Cook's account, and Ate Up With Motor says that BL was offering substantial rebates on new TR7s and TR8s by the 1981 model year.⁠2​3​5​21​11​16​22​12

Solihull and the right-hand-drive project, 1980–81

Rover's Solihull plant began building TR7s on 1 April 1980, a first batch of 1981 model-year cars was built at Canley in May and June, and car assembly at Canley stopped that August. The 1981 model year brought injection to every North American TR8 and, Cook notes, cloth seats in place of the plaid of the 1980 model year.

Britain was to have the TR8 too. According to the programme's product planner, as triumphtr8.com quotes him, a right-hand-drive "Home Market" TR8 was approved at the end of March 1980, and the first cars were built that April. By the time the last of the pilot run was finished, on 31 March 1981, the project had been cancelled at the first planning meeting of the year: his reason was that BL would not start selling and servicing a British V8 while the whole programme's future was in doubt. One of those cars, NWK 988W, went to BL Motorsport at Abingdon late in 1980 to try out a different engine and chassis specification for Britain and Europe.

Solihull also built cars for Americans in Europe. triumphtr8.com counts, from the build cards, more than 40 personal-export TR8s made between June and September 1981 for American and Canadian service personnel and diplomats, who could buy them free of tax.⁠17​23​24​2​25​26​27

The end, 1981

BL announced the end of the TR7 and TR8 in May 1981: the product planner, as triumphtr8.com quotes him, dates the notice to 14 May. In June BL decided to sell the right-hand-drive cars and its left-hand-drive development, test and experimental TR8s, and Canley's experimental records list 36 TR8s sold at BCA's auctions at Measham on five Fridays between 7 August and 4 September 1981. A few cars were kept back: the records list "North American Mothball Vehicles" kept against possible litigation, and one experimental car, EXP 923, stayed with the company until 2003.

The last TR8s were built that October. triumphtr8.com gives 408533, built on 12 October 1981, as the last by chassis number and 408405, finished on 20 October, as the last by date, and James TenCate of the Triumph Wedge Owners Association found the highest injected engine number he traced, 14E00799, in a car built on 12 October. The highest chassis number of any TR7 or TR8, 408534, belongs to a right-hand-drive TR7 convertible in the British Motor Museum's collection. Canada took some of the last as its 1982 models: an enthusiast site, tr8.com, recorded about 70 such TR8s, and Canadian dealers advertised them.

Cook's verdict is that "it took nine years from concept to production, by which time it was too late for both the TR8 and Triumph as a company", and he adds that by 1980 the American economy was weak and the pound strong against the dollar. Ate Up With Motor adds that the V8 arrived after the Iranian revolution had driven up the price of oil, and Lamm remembered 1981, "the TR8's last season in the States", as no better than 1980.⁠25​12​28​4​29​24​7​17​30​21​2​3

Total production

No one count of TR8s is agreed. BL's own table, the TR Drivers Club's and triumphtr8.com's, and the total Cook quotes from Kimberley's guide of 1981 give between them about 2,700 to 2,800, by counts that never state their rules; the versions page explains how the tables were kept. Identification sets every figure beside its source.⁠17​7​29​24​2​3

Rivals

The American magazines set the TR8 against four cars: the Chevrolet Corvette, the Datsun 280-ZX, the Mazda RX-7 and the Porsche 924. Their prices in 1980, as printed:

CarPricePrinted by
Mazda RX-7$8,295Road & Track, June 1980
Datsun 280-ZX$11,299Michael Lamm, 1999, for May 1980
Chevrolet Corvette$13,140Road & Track, June 1980
Chevrolet Corvette$15,599Michael Lamm, 1999, for May 1980
Porsche 924$16,770Michael Lamm, 1999, for May 1980

The TR8's own prices when new are in the specifications. Lamm set his figures for the rivals beside the TR8's to show the "stiff price competition" it faced, and Ate Up With Motor put the TR8 at about $2,000 more than a TR7 or a 280ZX and $4,000 more than an MGB.

It was quick for the money. Road & Track's comparison box put it between the RX-7, which took 9.2 seconds from rest to 97 km/h (60 mph), and the Corvette, which took 7.7, and Car and Driver found "only one sub-$20,000 sports car that can beat its speediness—the hoary old Corvette". Braking was its weak point: Road & Track's TR8 needed 55 m (179 ft) to stop from 97 km/h, the RX-7 46 m (151 ft).

The sales went the other way. No source read gives the rivals' American sales for 1980, but AROnline writes that the Datsun Z and the RX-7 had sold about 50,000 a year in America in some years, and Lamm recalled that Triumph's American sales of every model had fallen to 12,733 in 1979. On the track the TR8 did better: in 1980 TR8s won IMSA's GTO class at Sebring, against Porsches and Corvettes, and in four more races.⁠11​31​3​12​5​20

The TR7 and TR8

The TR8 was built where the TR7 was: at Speke in 1977 and 1978, at Canley from 1978 to 1980, and at Solihull in 1980 and 1981. How the plants were run, the strike that closed Speke and the move to Solihull belong to the TR7's story, and so do BL Motorsport's TR7 V8 rally cars, which raced on the TR8's recognition. This site keeps to the cars that left the factory as TR8s, and to the TR7s later given V8s that are taken for them.⁠17​12​1
