The cars : Triumph TR7/TR8 development story

The Triumph TR7 was the last of a great sports car line – although few would have believed it to be, when designing this important car back in the optimistic days of the early 1970s.

The TR7 looked like nothing else on the road, but couldn’t match the show with enough go. However, despite that, it went on to outlive the MGB, while becoming the best-selling TR of them all…

Triumph TR7: Last throw of the dice

Triumph TR7 front view

Sports cars were something that both BMC and Leyland Motors as separate companies had proved to be rather good at. In the USA, the MG Midget and MGB had enjoyed immense popularity, outselling their rivals, the Triumph Spitfire and TR6 by a considerable margin.

However, when BMC merged with Leyland Motors to form BLMC, new dilemmas began to rear their heads. It was fairly obvious that the MGB and TR6 were reaching the end of their useful lives – despite healthy sales in the USA and that being the case, the question of how to replace them would need to be answered before development of any new sports cars could commence.

The root of this dilemma was that, although MG and Triumph belonged to the same company following the merger of 1968, up to that point, they were rivals and subsequently, there was considerable overlap in BLMC’s sports car range.

The MG Midget and Triumph Spitfire were aimed at the same customers and the Triumph TR6, GT6 and MGB were not too far apart, either. The result was that there were five models competing in pretty much the same sector – and all selling in comparatively small numbers in comparison with the other sub-2.0 litre cars being produced by BLMC at the time.

MG and Triumph proposals

At the time of the merger, both MG at Abingdon and Triumph at Canley were already working on their own interpretations of how their new sports cars would appear and be engineered – and the contrast between both companies would prove to be highly interesting.

In Abingdon, MG had been working on a promising sports car, codenamed the ADO21, which was a shark-nosed two-seater sports car, which unusually for its time, sported a mid-engined configuration. One of the other interesting technical aspects of this car was the fact that the only major carry-overs from the BMH saloon car range were its engine and Hydrolastic suspension – it has been said by MG enthusiasts that this car was essentially an MGF, some 25 years ahead of its time.

MG’s option was the rakish ADO21. Sadly, its mid-engined configuration and hydrolastic suspension ruled it out of the running for the corporate sports car… BL wanted plain and simple for its US export

Over at Triumph, initial work had also started on its own sports car, codenamed, Bullet and, unlike the MG ADO21, this was a conventional front-engined car, using saloon car running gear. The cars may have conceptually been diametrically opposed, but elements of both cars would end up being incorporated in the final product.

Triumph Bullet
The Triumph Bullet offered everything that the Americans told the British what they wanted from their sports cars: it was simple mechanically (front-engined, rear-wheel drive), which gave a greater potential for long term reliability. As far as BL was concerned, that made it a preferable option to the ADO21 for the company’s corporate sports car

BLMC management knew it had to pitch any new sports cars at an increasingly sophisticated clientele with care – and the cars the company was currently selling were, to put it politely, getting over the hill. In the USA, buyers were turning to the offerings Datsun (the 240Z) and Porsche (the VW-Porsche 914) in increasingly large numbers.

Pragmatism or sophistication?

Whatever BLMC would serve up would need to be quick and reliable (to match the Datsun) and technically interesting (to match the mid-engined Porsche). Also new crash legislation was being introduced in the USA, which many informed people in the motor industry assumed would prove to be the death-knell of open-topped sports cars. Because of these pressures on BLMC and the fact that there was a massive need to develop a viable range of family cars, money and resources would only be released to develop one ‘corporate’ sports car.

Of course, the marketing issue would need to be finalised first and because of this, in late 1970, Mike Carver, then a Manager in Central Product Planning and Spen King travelled to the USA in order to sound out the dealers and try and understand what it was that would be required.

The fact that Spen King (at the time, the Chief Engineer at Triumph) would be so intimately involved in the early stages of the new car’s development ensured that Triumph as a marque would get the inside track in terms of development. This would be in spite of the fact that of the Corporation’s sports cars, it was the offerings from MG that were most in demand. Carver stated subsequently that this was in no way intended to be a full market research programme, but a series of, ‘extended conversations with relevant parties.’

Triumph TR7: What the Americans wanted

The result of these findings would prove surprising because they indicated that what the Americans really wanted was a conventionally-engineered front engine, rear-wheel-drive car. The reasoning behind this was that the Americans wanted reliability and the ability for a ‘quick fix’ should the car fail.

Once back in the UK, the Product Planners reasoned that this format also had advantages in terms of development – and the fact that it would be less costly for the company both in terms of time and finances. Donald Stokes wanted the company to have a product ready to sell by the mid-1970s and this tight deadline would be easier to meet if the product the company was developing a car that shared componentry with mass-produced stable mates.

Because the dealers wanted a car that occupied a similar place in the market to that of the biggest seller, the MGB, the advantages of the mid-engined layout were lessened significantly. Performance would not be great enough to exploit the handling advantages brought about by even weight distribution that comes with a mid-mounted engine and because the new car would be a two-seater, there was no advantage to be found in either configuration. In the end, it would come down to the budget: front-engine, rear-wheel drive it would be.

Triumph engineering wins out

Out of the MG and Triumph models in development, it was obvious that the Triumph Bullet would be the model to be honed into a production reality. Work on the Bullet had been ongoing since 1969; Triumph envisaging it as a combined GT6/TR6 replacement and prototypes were soon running with Triumph four and six-cylinder power units.

Once the green light had been given to the Bullet project by the BL Board, the full weight of the company’s resources were put behind the development of the new Triumph at the beginning of 1971.

Donald Stokes made it clear that it should be ready for introduction in 1975. The Bullet was being developed as a cheaper front-engined version of the VW-Porsche 914 and, as such, was not a full convertible, but a targa-top, rather like the Fiat X1/9 – this left a gap in the range for a full convertible and the MGB would be left to remain in production for as long as regulations allowed the company to sell rag-tops.

No convertibles needed – so they thought

Product Planning decided that even though the new car was conceived as a straight replacement for the MGB, it should be priced above the older car so there was no clash between old and new. Already, the Bullet was being moved away from its intended market, by the Product Planners – something that would happen again and again in the Corporation.

The conception of the car was finalised, but the finer details still had to be decided. Spen King was placed in charge of the development of the new car – and, in a theme common with the subsequent Rover SD1 and Austin Maestro, the package would offer no technical surprises.

Familiar technology underpins corporate sports car

Triumph Slant 4

The engine would be a development of the slant-four Dolomite engine (above), initially coming with a four-speed gearbox (developed from the Morris Marina) and live rear axle. Now that the ethos was for the production of a BLMC sports car (as opposed to a Triumph sports car), the option of a Triumph straight-six powered version was dropped in favour of the use of the Rover V8 engine, which at the time was being used in the Rover P6B, P5B and Range Rover.

King was an expert of honing conventional components into something comparable with more exotic rivals – and, even though the rear suspension was not independent, with careful development and thoughtful axle location, it proved possible to make the car ride and handle at least as well as its foreign rivals – and certainly better than the aged MGB and TR6.

At this point in time, it became obvious to everyone that the Bullet should be marketed as a Triumph – MG still had the MGB to sell, but the Triumph range would be cut at the expense of the GT6 and TR6.

Harris Mann enters the equation

During the early stages of development at Longbridge, there were TR7-shaped clay models produced wearing the ‘MG Magna’ nameplate, but it was a half-hearted effort, really. The name of MG was synonymous with open-topped sports cars in the USA, and this meant that, while the MGB remained in production, it would not make sense to develop an MG-badged TR7.

Harris Mann Bullet sketch
Early Harris Mann styling sketch shows that the TR7’s essential character made it through to production, although the final result was somewhat watered-down from this bold proposal

Now it was settled that the new Triumph TR7 would not directly replace the MGB, but would also fight competitors higher up the price scale, its simplicity could prove to be a hurdle to sales. Even with the extra equipment added to the car in order to become a price replacement for the TR6 or GT6, the mechanical layout as chosen by Spen King did lead to the impression that the car was giving something away in terms of sophistication to its foreign rivals.

With this in mind, the Longbridge studios were asked to re-style the car, in order to increase its appeal and so, following his work on Project Condor, the ADO71 and the impressive Zanda design concept, Harris Mann was handed the task…

1971 and the Triumph TR7 styling is almost finalised. Impact absorbing bumpers are incorporated and compared with the styling of the earlier Bullet proposal, looks good while managing to integrate the monolithic US-style bumpers, and this model does without the targa roof of the earlier car. This particular clay model sports the ‘MG Magna’ badge, but in reality, thanks to the way the sports car plan shook out, the MG TR7 was never much more than a pipedream – at this stage

Adding a premium feel into the mix

Harris Mann honed the styling in order to give the TR7 a more expensive look – also incorporating the 5mph impact absorbing bumpers that the car would require in order to meet upcoming US regulations. The most startling aspect of the styling though, was reserved for the belt-line – in order to emphasise the low nose/high tail stance of the TR7, this was slashed down the side of the car starting high at the rear end and tapering towards the front, ending just before the front wheel.

It certainly gave the TR7 a degree of character and identity that the Bullet lacked. Elements of the ADO21 design were also included, especially around the area of its pointed nose and pop-up headlights. It was at this point that the targa top arrangement of the Bullet was dropped because the spectre of a complete ban on convertibles in the USA was still hanging over the car industry.

It was still was not known whether this arrangement would meet such regulations. Happily for the management (but perhaps less so for the dealers), the Triumph TR7 would feature a ‘family’ look shared with its Austin Morris stable mates, dropping all stylistic links with Triumphs of the past.

Triumph TR7 design progresses rapidly

As development progressed, by 1972, it became clear that the TR7 should be the starting point for a modest range of sports cars – and the TR7 in the form it was launched would be the base model in this range. Because it was obvious that the torquey Rover V8 engine would suit the car perfectly, this would head the range.

Below that, the 16-Valve version of the slant-four Dolomite engine, at the time under development by Spen King and being readied for the Dolomite Sprint was also earmarked to form the basis of the TR7 Sprint. Beyond this extending of the range of engines, at the point that the TR7 was nearing announcement, development of a 2+2 version commenced, with a view to widening the appeal of the corporate sports car.

The thinking behind this car, called the Triumph Lynx, was that with its extended accommodation, it could be an effective competitor to the Ford Capri – a car which was proving to be a runaway hit for Ford and, in the process, was re-inventing the sports car market in the UK and Europe. The V8-engined Triumph Lynx would be pressed into service as a replacement for the troubled Triumph Stag, which at the time, was costing the company a packet in warranty costs.

The TR7 is go… but for the US only

Triumph TR7 US-spec

Speke was the factory chosen to build the TR7 from the time of its launch to the world’s press in the USA at the start of 1975 – and, because the US market was so important to British Leyland, the usual process of final testing and honing was dropped in order to get the car on sale as early as possible.

The decision was also taken to launch the Triumph TR7 in the USA only, European and British cars coming on stream later, once production could be ramped-up in order to meet demand. The onus was now very much on the Speke workforce to produce the car at an acceptable level of quality – reputations were built on first impressions and, if the car was built well, the positive image would remain with the car throughout its life.

Sadly, it was inevitable that they did not.

Safety and comfort take pole position

Technically, the car may not have been exactly ground breaking, but there were a few points worth lauding the car for at the time of its launch. Safety was big news and the TR7 was designed very much with this in mind – the monocoque had been designed to meet all upcoming US crash regulations and intelligent detailing in the structure meant that the car would prove to score well in passive safety terms.

Although it appeared that the car incorporated an integral roll-hoop, it did not – but the rear three-quarter pillar was immensely strong, thanks to the box sections incorporated within, all the way up to the roofline and a cant rail over the windows.

Triumph TR7 cutaway

One interesting aspect of the crash structure (and one that marked the car as being ahead of the game in this respect) was that the front section of the body shell did not contribute much in the event of a head-on collision, but merely acted as a crumple zone. The major energy in such a collision was in fact absorbed by the wheels against the bulkhead and the engine against the scuttle.

It may seem bizarre now, that the movement of the engine in the event of a collision was a desirable state of affairs, but because the scuttle intruded very little into the seating area of the passenger compartment, it was not considered to be an undesirable trait. The strength at the front of the car was also aided by its X-shaped front subframe and its less-than-pretty 5mph bumpers which were made from box-section steel and covered by self-skinning methane foam.

Controversial styling raises awareness

Bodyshell strength was also above average for the time (but not in the class of the ADO17 saloon) at 7500lb ft per degree, but it was not the safety or strength of the Triumph TR7’s body that drew comment, but its style. In an amusing tale that has now entered into the folklore of motoring history, it was Giorgetto Giugiaro that summed up the feelings of many people.

On his first viewing of the car at the Geneva Motor Show in 1975, he is said to have paused to take a long look at the TR7. Pondering its styling, he is said to have looked at it in a puzzled way and then walked around the car, only to say, ‘Oh my God! They’ve done it to the other side as well.’

This was no doubt a reference to the fact that in the development of new model styling, often different styling solutions are tried out on both sides of a clay model of the car – and Giugiaro obviously thought that the TR7 looked so bizarre that it could in no way be a production car!

It is easy to take cheap shots at the styling of the Triumph TR7, but alongside the Leyland Princess, it certainly showed that BLMC were keen on producing interestingly styled – bold – designs. It is just a shame that other factors conspired to play against the success of these cars before they had a chance to establish themselves on the market.

Production begins, quality stories follow

Triumph TR7 made its US debut at the 1975 Chicago Motor Show (Picture: RunWhenParked)

Early quality niggles were not evident at the time of the launch of the Triumph TR7 and, because it was an export-only car, the US journalists were reporting on the car a full year ahead of their counterparts on the domestic market. The launch passed off without hitch and generally the US press were impressed with the car, if a little unimpressed with the ‘challenging’ styling.

There were certainly no complaints regarding the handling and ride of the TR7, but what impressed even more than the chassis was the comfort and habitability of the passenger compartment: it was certainly viewed as a much more civilised car than its predecessors.

Anti-emissions equipment hampers Triumph TR7

Because of the strict emission laws that were in force in the USA by 1975, extensive anti-smog equipment was installed in the TR7 and the eight-valve 2.0-litre engine, which was not exactly the most powerful engine to start with, suffered badly from the resultant power loss.

In the USA, the TR7 was offered in two states of tune in order to meet the varying emission regulations within the country: 90bhp from twin-Stromberg carburettors in 49-State tune and a paltry 76bhp in single-carburettor California tune. In reality, this fact demonstrated that British Leyland had no suitable ‘federal’ engine in their line-up and the company was therefore suffering as a result.

Unsurprisingly, the American press was therefore calling for a hike in power, something that British Leyland knew was in the pipeline.

UK debut goes without (too many) problems

Triumph TR7 interior
One of the most impressive parts of the Triumph TR7 was its interior, which proved to be spacious (for a two-seater) and stylish in its execution. This early UK-specification car did without the US-style steering wheel, with its large and clumsy central crash pad. What is also evident from this picture is that its interior architecture owed nothing to its sports car predecessors or its saloon car stablemates

The UK had to wait until 19 May 1976 for the TR7 to go on sale and the press generally treated this date as the time to treat it as a new model launch. Various detail changes were made to the TR7 in order to be more suited to European buying tastes – not least the use of smaller rear bumpers and an engine that was not strangulated by USA anti-emissions equipment: the higher compression, twin-SU version of the engine was used, producing a more realistic 105bhp.

This gave the car more class-competitive performance with a (Triumph-claimed) 0-60mph time of 9.4 seconds and top speed of 110mph, as opposed to 11.0 seconds and 107mph of its Federal cousin – of course, this was still easy meat for the 3.0-litre Ford Capri.

However, British Leyland had thoughtfully decided to launch the TR7 at a competitive price of £2999, which was some £696 (or, in those pre-inflationary times, over 20% less) than the Capri.

Triumph TR7: what the papers said

Triumph TR7 brochure shot

Autocar reported on the TR7 at the time of the UK launch and came away impressed with the car as a whole, but as always there were certain reservations. ‘Performance-wise, the TR7 is no sluggard. It tries hard, a little too obviously, and is great fun in the tighter country road that is its favourite going. On motorways and wide, gently curving roads, its sporting pretensions are not backed up with quite enough power.’

Again, the chassis was praised for being greater than the sum of its parts and overall, they came away pleased: ‘… it will find a wider public when they hack off the lid and give it a soft top’. ‘When the TR5 appeared, a monthly fringe-contemporary described it as ‘an engine in search of a chassis’. The TR7 is sort of revenge for that remark, or at any rate, a reverse – a chassis in search of an engine.’

Inevitably, because of the passing resemblance between the two cars, the Triumph TR7 and Fiat X1/9 would end up being compared – and a year after the launch of the TR7 in this country, Autocar magazine did just that. Interestingly, what emerged from this article was not so much the relative merits of both cars, but what the public at large thought of them.

An acid test from the public

‘…The acid test, we took the Fiat and the TR7 to the Red Lion in Mayfair. A lunchtime hangout for advertising executives and director’s secretaries, we realised that its verdict would be the final one. Which one would he/she rather go home/be taken home in? That white TR7 or the green X1/9?

“The green one,” said the willowy blonde who was obviously good at more than shorthand or typing. “Because my boyfriend’s got a green car. I think they’re great.”

Whereupon a pair of skin-tight white jeans slinks in, sits down on the stool by the bar and looks demurely across at both cars. The long lashes caress first the TR7, then the Fiat.

“Well?” I ask, putting on my road tester’s voice. “Well, what do you think of those cars? Which would you rather be driven home tonight in?” She glares at me at first, then shuffles in her seat when she realizes that it is just a questionnaire.

“What’s the prize for getting it right?” she asks.

“One of these cars,” I joke. “Oh well, in that case, the green one. I think it’s a very feminine car. I wouldn’t like to drive it home, mind. Just sit alongside some Italian-looking guy. It looks much faster and more expensive than the other one. It looks too fast for a woman.”‘

Was the TR7 lacking in sex appeal?

Triumph TR7 press photo

And that was the problem. The Triumph did not have the immediate sex appeal of the Italian car and Peter Windsor’s findings in that London pub certainly very potently demonstrated the fact. Inexpensive modifications to the TR7 could have easily reversed this situation, firstly the utilisation of more appealing colours and paint schemes, for a start: the TR7 V8 rally car was regarded by all that saw it as a fantastic looking car with its blue and white paint scheme and wider Minilite-style wheels, but the colour scheme was sadly not carried over to the production car.

In October of that year, Speke workers went on strike – and the end result of this was that any modifications that the company did try and incorporate into the TR7 could not be added. No one was building the cars. Those that were coming off the production line at Speke were proving to be suffering from indifferent build quality – and, as a result, were afflicted by the same, depressing reliability issues that also affected the products of Longbridge and Cowley.

As we have seen, the net result of all this strife was the closure of the Speke factory and the transfer of the TR7 production line to Canley, near Coventry – this disruption to production cost the company dearly as people who would have bought the TR7 in 1977 and 1978 were sadly forced to look elsewhere. It took time to transfer the production line and then further time to get the Canley line up to speed.

The ramifications of Speke’s closure

Apart from the death of the Lynx and the TR7 Sprint, the Speke closure also marked the end of any further serious development of the car. Michael Edwardes was concentrating the company’s efforts on ensuring that what little money was being given to the company by the Government was channelled into the development of the LC8 and LC10 hatchbacks.

Luckily, the V8 version of the car was nearing completion at this time – and because the US market demanded this model, its future was assured. Also in 1976, and as a result of the fact that the impending ban on convertible cars in the USA proved to amount to nothing more than a scare story, work began on producing a drop head version of the TR7 ‘coupé’.

Again because of pressure from the dealers in the USA and the fact that development of this car was nearing completion and proved to be relatively inexpensive, its future was also assured.

Triumph TR7’s Canley improvements

Once Canley did get up to speed, the improvement in the Triumph TR7 became immediately apparent: the quality of final assembly was of a higher order and a small round of changes was made to the car.

These included the fitment of the 77mm five-speed gearbox from the Rover SD1 and cosmetic improvements, such as the widening of the range of colours, a smartening of interior trim and the addition of a bonnet power bulge – in anticipation of the upcoming TR8.

The opportunity was also taken to incorporate running changes to the car, with the upgrading of the electrics, instrumentation and cooling – all part of the standard modifications that would come part and parcel during the production run of any car but whichh, in the case of the TR7 and all the strife at Speke, the company had been unable to implement.

Opening up to the elements

Triumph TR7 Convertible

The convertible version appeared soon after in May 1979 – but, again disappointingly for customers in the UK and Europe, its sales were limited to the USA. It was immediately apparent to all that, in this form, the styling was everything that the TR7 should have been right from launch – so right were its lines. No longer was the ‘turret top’ an awkward looking car, but it has gone through the transition to become a pretty and striking open-topped car.

At the same time, the TR8 also entered pre-production at Canley and a few of these models were in the hard-topped bodyshell, but sensibly, when the pre-production run became series production, the TR8 was offered only in the convertible body style.

The structure of the bodyshell was strengthened in order to compensate for the lack of roof – an additional strengthening box section being installed behind the seats, which linked the B-posts together. Extra strengthening was also added to the quarter panels and, curiously, BL’s Engineers also incorporated an end-weighted front bumper, which was an expedient to lessen the effects of scuttle shake. Because of thoughtful design and against subsequent trends, the drop-head version was slightly lighter than the fixed-head version.

Convertible and TR8 boost appeal…

Triumph TR8
1980 heralded the introduction of the Triumph TR8, but unfortunately for British Triumph fans, it was made available in the USA only. Strong and smooth Rover V8 engine allied with the convertible body style made for an extremely appealing car – a kind of latter-day MGB-V8, in fact. Performance and economy were excellent and the aluminium alloy engine was perfectly suited to the job of being the power unit for a ragtop. TVR would make a good living through building such cars in later years

The USA market recovered as a result of the launch of the convertible model, but it could not have come at a worse time, as the World slipped into global recession following the Iranian crisis in 1979. This factor alone did not affect the sales of the Triumph in the USA, but when the exchange rates moved in favour of a strong pound, it certainly affected the profitability of the company’s sports cars in the USA.

When the TR8 went on general sale in the USA in May 1980, it was met with unanimous praise, being hailed as nothing less than ‘the re-invention of the Sports Car’, by Car & Driver magazine.

When the convertible was launched in the UK in March 1980, it was also greeted with enthusiasm by the motoring press. Motor magazine might have been more reserved than their American counterparts, but concluded in its road test that, ‘BL’s long-awaited TR7 drop-head represents a significant development over the fixed-head version. Lively performance with plenty of mid-range torque with long legged fifth gear.’

V8 denied to the UK

In Motor’s hands, it had also proven to be slightly quicker and more economical than the hard-topped version. What the British were denied though was the TR8 version, of which the Americans received the lion’s share of the 2715-unit production run.

35 were produced in UK specification, but unfortunately, events overtook the TR7 family of cars and, if this glowing report from CAR magazine in December 1980 is anything to go by, we were shortchanged:

‘I asked myself more than once the deadly serious question: “would I spend my own hard-earned money on a TR8?” This is not a fantasy. This car is expensive by American standards, and yet no more than a Mazda RX7 or a Datsun 280Z, and a lot cheaper than comparably equipped Chevrolet Corvette. And all round it will outperform them all. “Decidedly yes”, I answer each time.’

In conclusion, ‘When the TR8 is launched in Britain next year there will be nothing in its class to touch it, save perhaps the Porsche 924. But don’t expect to be able to buy it for what the Americans pay, even though the British model (without the emission control equipment) will be considerably cheaper to make…’

Triumph TR7 and TR8: the end…

Late in 1980, production of the TR7 and TR8 was moved, yet again, to the relatively new Solihull factory, south of Birmingham to be produced alongside the Rover SD1. In reality, this move, which spelt the death-knell for car production at Canley, also proved to be the death knell for the Triumph TR7 and TR8 itself, because Michael Edwardes had plans on the cards to put this massive factory on ice.

In May 1981, BL made its plans to kill the TR7 public, but Ray Horrocks made it clear that production could be continued if demand for the car improved ‘significantly’. Needless to say, it did not – stockpiles of unsold TR7s mounted up and, as a result, the closure of Solihull went ahead, a further 3000 jobs at BL were lost, as well as resultant losses at the Speke and Swindon body pressing plants and the closure of the Wellingborough foundry in Northamptonshire.

Sports cars no longer figured in the plans of the company and, even though the Abingdon factory was being wound-up at the same time and demand in the USA for the MG sports cars was still reasonably buoyant (although down by almost fifty per cent since 1977), the agreeable option of moving TR production to Abingdon and introducing the MG Boxer was not taken.

What might have been…

Would the MG-badged, O-Series powered Boxer or the Broadside family have sold any better? Evidence would suggest that it may have sold enough to buoy the company enough to make it to the good years of the late-1980s: at the time of the MG closure in 1980, American dealers pleaded directly to Michael Edwardes to save the marque – and produced an order book full of unfulfilled orders for MGs.

Certainly, using the O-Series engine would have trimmed costs; rationalisation always does – as would the fact that without question the Abingdon factory was unique in the company during the ‘dark’ years.

Its workforce did not resort to industrial action and enjoyed a good relationship with their management – thus, there would not have been anywhere near the same level of lost production due to strike action.

  1. The photo of ADO21 near the beginning of the piece is amazing……..was that front end designed to slice the legs off any pedestrians who got in the way?

  2. The Lynx was a another lost opportunity, would have stacked up well against the Capri, Manta and scirroco of the day. The Japanese were producing this kind of car in the seventies as well. In an ideal world there would have been a nice progression of models (TR7 -> Lynx -> SD1 -> XJ6) for US customers to “grow” into as their age, needs and finances changed.

  3. A shame the V8 was never an official model in Britain as this would have really taken on the likes of Porsche for less money.

  4. In the days when cars where tuned up at home saw the TR7 at its launch at the Motor show in London. at last a sports car to move on owned 10 now 2 V8 hard and soft top cars,even now thanks to the old farts network they are affordable.even today people tinker with road test to make them look slower ie Practical Classics feb 2011.

  5. The Lynx would have drawn sales away from Capri’s and Manta’s/Cavaliers had it proceeded andquality had been right. Alas another project that got kicked into touch…

  6. Have owned many TR7 and V8 conversions and have to say that they are fantastic cars.Like all cars they have their idiosyncracies but compared with modern, all electronic cars, the TR7 is simple and easy to maintain

  7. A pity the Triumph Lynx never entered production, I could easily see it having a 12 + year production run (give or take) and with Rover V8 power (or S/O/M-Series Turbo & KV8 / KV6 engines) combined with a modern-looking restyle inspired by the Grinnall TR8 (with Porsche 928-like headlights) would have found it a very tempting proposition.

    Out of interest, does anyone know where I can find pictures of the TR7-based MG Boxer?

    The only thing I was able to find is a reference on the Triumph TR7 wiki page.

  8. Interesting that the picture of the “Broadside coupé in actuality” looks rather like a small 2 door SD1, I rather like its looks personally.

  9. Harris Mann- a name that strikes fear into the hearts of men…
    Always seems to me that there was a massive gulf between the guys who designed and the people who were expected to buy these cars- many British (and French designers) who were drafted in to help produce cars unfortunately didn’t understand the critical US market and what it required.

  10. Interesting how well the MG RV8 sold, especially in Japan- Old fashioned, crude but powerful and timeless; just what the Japanese and Americans would expect and like about a British sportscar. The TR7 wasn’t a bad machine, just that it wasnt what the Americans really understood or wanted.

  11. “Wasn’t the Acclaim the last of a great Triumph line?”

    No, the Acclaim was a re-badged Honda Ballade.

    The TR7 was so much a nearly car. It nearly looked right, it nearly had a good engine and it was nearly built properly. Speke quality control was non-existent, not helped by a bolshie, strike prone workforce.

    I think the looks are more acceptable in 2013 than they were in the 1980s!

  12. does anyone else remember a Green or (possibly Brown) Lynx/Broadside in the background in a late 1980’s episode of Eastenders? was I smoking too much?

  13. Rubbish. As you Brits say. Come on for a modest priced vehical for the 70’s U.S. market this topped the cake. Think of all the junk cars made in the U.S. from 75-81 one of the worst era in automotive history. There were not many gems in those 5 year and the Triumph Tr7 surly was not the worst. Using a sd1/buick v8 was a great option sorry it didn’t take off for you across the pond.

  14. I currently own a genuine factory built TR8 after owning 2 TR7’s. The DHC 8 is an incredible car and even to-day, people come up to me and ask “what is it?” The TR7 was a much maligned car however my experience was nothing like that. The first one was stolen early on and its replacement which is till in the family, has done nearlt 1 million k’s!! Yes it has had its annoyances but it can’t be killed. It will eventually undergo restoration. BMW should do something about relaunching this marque.

  15. So it was 1976, and walking home from school one sunny afternoon, I came by the local Kennings garage in the village where I grew up, ( when villages n the Peak District still had car dealers). I was transfixed when I came upon a yellow TR7, a yellow Rover SD1 and a white XJ coupe in the showroom window. A moment I have never forgotten. Sine then I have had 3 TR7’s. an enduring love affair, you might say, and a massively underrated car.

  16. My first (only) TR7 came my way by chance, shortly after returning to Toronto in late 1975 from London, U.K., where I had owned a Jensen-Healy. I bought the TR7 – a “demo” – and found it a dream of a car, small and all that it was. The car made many journeys into the heartland of Massachusetts, where friends lived, and did the trips in record times. It was the Toronto winters – city streets under three feet of snow, etc. – that did in relations between me and the TR7. I spent too much time atop city streets’ snows, and without the chance of having the wheels make contact with anything resembling traction. But, my, did that car ever attract envious looks from all who saw it.

    I have owned three cars in my life that I thought classics -a 1956 Riley 2.5 Pathfinder, the aforementioned Jensen-Healy (1974), and the TR7 (1975), each a British car, each a treat to drive. The Healy wins the debate, but the other two were close enough in the outcome to make no appreciable difference.

    And the Pathfinder, I should say, was a terrific design, for it placed the gear-shift to my right – between the bench seat and the driver’s door, precisely where anyone who learned to drive in North America would want to find that gear-shift, to the left-hand driver’s right. I’m not sure there has ever been a car like this one in that respect. I paid twenty quid for this car, something more for each of the other two.


  17. I served my apprenticeship at Cowley starting in 1968 and went on to work in one of the DO’s. The whole place was rotten to the core and the so called management, an old boys club, were feathering their own nests before the whole show closed down. Very sad that the blame is laid on the Unions when most of the management were unqualified cowboys. They destroyed our motor industry which had a great deal of technical know how and a great deal of qualified workers. The products were all wrong and the BL nonsense was the end of the road.

  18. Even though the TR7 was sold as a Triumph and even featured a 2-litre Triumph Slant-Four engine, one cannot help but feel this car is basically an MG rather than a Triumph.

    Carrying over elements of the MG ADO21 and being styled by Harris Mann further cements the view of the TR7 being an MGB replacement rather than a replacement for the Triumph TR6, giving some insight of how the MG marque could have evolved between the MGB and the M-Car and much more.

  19. Keith:

    I don’t know why I missed this gem in earlier readings, but it brought me up short: “… the US journalists were reporting on the car a full year ahead of their counterparts on the domestic market. The launch passed off without hitch and generally the US press were impressed with the car, if a little unimpressed with the ‘challenging’ styling.”

    I remember sitting in the AutoWeek offices in the mid 1980s as the late Leon Mandel regaled us with stories from car launches past. It was an unusual event in that Leon didn’t often sit down for “bull” sessions, but his description of the U.S. launch for the TR7 was much different than the quote above. According to Leon, Triumph encouraged the attendees on each wave to drive a car back to their home base in hopes of showcase the car’s reliability and emphasize its suitability for the U.S. market. “It was a major mistake,” he deadpanned, telling about cars stranded across the country as company personnel scrambled to get the offending vehicles to nearby dealers for repair. A few, he said, were swapped for another TR7, and the journalists sent on their way.

    The truth of this is unknown, though I am sure a certain amount of embellishment crept. Leon is gone and so is the TR7, but the story certainly played to the feeling that British cars of the time would leave its passengers stranded at the worst possible time, and without warning. Not that I listened. There’s a Lotus Elan S4 in the garage nearing completion and a Cortina Mk. 2 waiting its turn.

  20. @ Chris Sawyer, the Speke built TR7 was a joke, it suffered from terrible build quality, gearboxes that failed prematurely, rust issues and electrical faults. Also being built by a strike happy and lazy workforce didn’t help. A real shame as the car looked good, could top 110 mph( when this was impressive for a 2 litre) and wasn’t too expensive to run. Things did come right with the TR7 when production was moved to Canley, but it was too late.

  21. The TR7 came out when I was in college, 1975. Always like British sports cars. Eventually bought a 1980, Brooklands green TR7 convertible in September 1981. At the time factory was giving a $1000 rebate just to rid inventory.
    I still own this car.
    Most cars of the 1970’s were not very good due to emmision controls, under powered. The TR7 is better known for it’s road handling.
    I believe the TR7/TR8 still has a good story to tell.

  22. The TR7 indirectly replaced the elderly and underpowered MG sports cars when these were axed in 1980. People often see cars like the MGB through rose tinted glasses, but by the late seventies, the MGB was an elderly design that struggled to beat 100 mph and sales were falling in Britain. The TR7, with its radical wedge design and pop up headlights, looked far more contemporary and exciting.

      • While understanding the Marina carried over much from the Minor (with others comparing the MGB to the Sherpa), is it known to what degree the Marina and MGB were either related to each other or at least to the extent they shared mechanicals with each other?

        Despite the MGB being an outdated design long overdue replacement (the EX234 being arguably a better direct replacement than the TR7), the fact the Marina TC could outrun it only highlights the MGB should have featured a 2-litre B-Series / etc from the outset.

  23. A big, big shame, I really liked the TR7 and had the TR8 been sold in Europe, then things could have been so much different. This really would have been the dog’s you know whats and could have been a British supercar for a reasonable amount of money. Sad to say, it never came to pass and the TR7 and 8 passed into history 38 years ago, effectively ending Triumph, which lingered on assembling a Honda Ballade under licence for three years.

  24. One thing I will say is how gloriously un PC this article about the TR7 is, with its photos of models draped over the car and the Autocar report about a woman who was good at more than shorthand. It makes you nostalgic for an era when people didn’t get so hung up about a pretty girl advertising a sports car and where millions of men could enjoy acts like Pans People without being called sexist.

  25. Does anybody know where the building/hotel is shown behind the white P reg TR7 in one of the pictures in this article?

  26. Thanks so much Dave. With your help it was easy to identify as Cap Sa Sal. It was an amazing hotel for the rich and famous in the 60s. Then after a period of decline it has been renovated as high end apartments. Thanks again.

  27. So a TR8 could beat a Corvette, huh? Too bad the quality of the early TR7 was so bad my co-worker bought his new about 1975 and it was always in the shop. Datsun ate BL’s lunch with their Z cars.

    • @ Karlson, the Corvette had been hobbled by emissions controls in the late seventies and, like most American performance cars then, could be seen off by smaller engined imported cars. The Nissan Z cars( though less so the 280 model) combined decent performance, reliability and relatively good economy( mid 20s mpg) at a reasonable price.

  28. I still think the original Triumph Bullet/Lynx with the square nose would have been a better bet, especially with the 2 body styles. A definite mistake too to not continue development of the targa roof, considering the X1/9 did have one.

    In particular that original Lynx was to me far more attractive and more of a 240Z rival than the later TR7 based Lynx, which looked too much like a sports hatchback (like the Cavalier/Manta Sports Hatch).

    But then the Speke strikes and build quality would have stuffed them just as badly anyway.
