Triumph TR7 Coupe
The fixed head coupé (FHC), as British Leyland listed it: the TR7's first body, its only one until 1979 and built to the end, at Speke, then Canley, then Solihull, from 1974 to 1981.

For its first four years the TR7 was a coupé and nothing else, a two-seater with a fixed steel roof and a body that carried its own strength. When the convertible came, in 1979, the coupé carried on beside it to the end of production, built in each of the TR7's three factories in turn. It began with a single bulge on its bonnet (hood) and a four-speed gearbox (transmission), and ended with a second bulge, five speeds and a new badge. The figures for each are in the specifications below.source 1source 2source 3
Why a coupé

It was meant to have an opening roof. The full-size mock-ups that became the TR7 had a lift-out targa panel. It was hard to engineer, and the American safety rules being drafted looked set to ban open cars, so the panel went and the roof became fixed. The roof that resulted was not a hoop over a hole. AROnline describes a strong box structure in each rear quarter and a rail along the top of the door openings, tying the roof to the body, with a torsional stiffness of about 10,200 Nm (7,500 lb ft) per degree, and the doors had side-intrusion beams.
Some of the coupé's details came from the car it might have been. Ate Up With Motor calls the five vents on the bonnet, at the foot of the windscreen (windshield), a vestige of the grilles on the MG Magna mock-up.source 2source 3source 4
Speke, 1974–78
The first coupés, built at Speke, in Liverpool, had a four-speed gearbox. The American car previewed in 1975 had the Dolomite saloon's (sedan's) gearbox ratios and a 3.63:1 axle, and air conditioning as an option; for the 1976 model year, five-speed and automatic gearboxes joined the list of options. Their bonnets had a single central bulge between the louvred panels. Inside, the British cars of 1976 were black, with seats in a nylon trim called Broadcord, until tartan inserts arrived in March 1977; early that year, too, shorter springs lowered the car by about 25 mm (1 in).
Speke's coupés carry commission numbers beginning ACL, for the American cars of the 1975 and 1976 model years, ACG, for Britain, Europe and Australia, and ACW, for the American cars of the 1977 and 1978 model years. The strike of 1977–78 stopped the line for about four months, and Speke built its last TR7s in the spring of 1978, before it closed in May.source 1source 5source 6source 7source 8source 2

Canley, 1978–80
The move to Canley brought the biggest set of changes in the coupé's life. The five-speed gearbox became standard, with the Rover SD1's type of axle and bigger rear brake drums, although automatic cars kept the old axle and tyres; the automatic cost £219 more in 1979. The badges were new, with a laurel wreath on the nose in place of the earlier badge, and the cooling was revised, with a flap to feed warm air to the carburettors. The headlamp motors were sealed, the seats had more padding, the body was given an anti-chip coating and the fuses were reorganised. The later Canley cars, and the Solihull cars, also had the second bulge on the bonnet that was made for the V8.
Motor Sport, trying a Canley coupé in 1979, found "the attractive, plaid-trimmed seats are most comfortable".
In general appointments and comfort the TR7 comes much nearer to saloon car quality than most sports cars and in that respect is easy to live with.
Canley's coupés carry the prefixes TCG, for Britain and Europe, and TCW, for North America, until the VINs of October 1979, which carry T as the assembly-plant letter.source 9source 3source 2

Solihull, 1980–81
The coupé moved to Solihull with the rest of the line in 1980. For Britain that year it had alloy wheels as standard, and a front spoiler, as the new drophead did; Motor Sport noted that it cost £217 more than the drophead. The last cars were trimmed in velour, by Wikipedia's account, which cites Bill Piggott's originality guide. BL's figures show coupés still being built in 1981, most of them for the home market. No source read says whether coupés of the 1981 model year were sold in America.
Three things tell the factories' coupés apart, though badges can be changed and only the numbers are proof:
The nose
The laurel-wreath badge arrived with the Canley cars; the last Solihull cars have a small round one, Wikipedia says, citing Piggott.
The bonnet
The Speke cars have one bulge; the later Canley cars and the Solihull cars have two.
The number
A commission number's first letter is A at Speke and T at Canley; on the VINs from October 1979, the assembly-plant letter tells Canley from Solihull.

On the road
The testers liked the coupé's cockpit, its ride and, in 1976, its handling, and disliked its brakes and its buzzy engine. Of the American car previewed in London, Motor Sport wrote:
'Speedy' this car is not, the maximum speed being 107 m.p.h., but it is said to be economical.
In Britain in 1976 the magazine's verdict was that its test car "felt characterless", largely because the roadholding and handling were too good for the performance, and it found the brakes wanting. Three years later the brakes were still its complaint, and so was the price: for what the TR7 then cost, it wrote, the enthusiast would be better off with an Escort RS2000 or a Fiat Mirafiori Sport, and "'Posers' might choose the TR7". At the British launch the coupé had cost £16 more than the RS2000 and £696 less than a 3.0-litre Capri; the rivals and the road tests follow the comparison through the car's life.source 6source 7source 9source 3
