On the trail of the enigmatic Argyll
Who says the ‘Car Guessing Game’ is no more than a bit of pointless froth? Around twelve years ago now, in a Celtic riposte on this now-defunct forum game to the all-conquering Aussies, I posted up a picture of part of the Argyll Turbo GT, built just ten miles from mother’s home town in Kintyre.
For the record, it was guessed in short order by one Keith Adams, but searching for a suitable image brought home how little information is published about the Argyll – a road test of the first Rover V8-engined prototype in the September 1976 issue of CAR, and some rather lightweight and contradictory web articles were all I could find. I decided that learning more could be a worthwhile project.
On my first available free Monday, I set off for Tayvallich, a yachting haven and lobster fishing village on a narrow neck of land between Loch Sween and the Sound of Jura given on a website as the address of the Minnow Fish Carburettor company. Having taken in the scenery and a good meal, I made local inquiries about the whereabouts of Minnow House and learned a quick lesson about the reliability of website information.
Tracking down the enigmatic Argyll Turbo GT
A call from the Post Office ‘phone (Tayvallich may be less than 100 miles from Glasgow, but it remains a stranger to mobile communications…) and I’m speaking to Bob Henderson himself, turbocharging guru, developer of the Minnow-Fish carburettor and creator of the Argyll Turbo GT.
Inquiring as to his whereabouts, I was told ‘where we’ve always been’. Lochgilphead, on a fiord off Loch Fyne, is only ten miles away – I was off down the road as quickly as is prudent on single-track roads at the height of the tourist season.
Bob Henderson appeared from behind his XK120, parked in the Minnow House yard, with a variety of other interesting machinery – a Nissan Pulsar GT-R, a Rover P4 105R, and several non-GM Saab 900 Turbos. I had arrived at a good time. Minnow Fish’s dynamometer was being recalibrated, necessitating a break in the workload.
Spending an afternoon with Bob Henderson
It was an absolute privilege to spend an afternoon with a true automotive and engineering luminary. Subjects discussed included the A and K-Series engines, his previous career as Chief Engineer of Short Aviation, the Highlands and Islands Development Board, colonial Malaya, Jaguar under Leyland, Lord Stokes (a Henderson villain!), the relative importance of thermal and volumetric efficiency and, just occasionally, Argylls.
I’d arrived just a fortnight too early to see a road-going Argyll. The silver example owned by Andrew Smith, former Scottish autocross champion and partner in the original venture, would shortly be readied for a return to the road.
Even in a dark corner of the rambling former laundry which has been Minnow Fish’s base for over 35 years, the striking proportions and clever design features, such as the ‘optical trough’ for rear vision, and the ingenious fixed louvred headlights, were clearly evident.
Argyll Motors: an interesting set-up
Despite its development in the forests of Argyll and rally stages in the Grampians, this is no Stratos-like compact rally weapon. It is instead a generously proportioned grand tourer, with a longitudinally-mounted V6 engine and 2+2 seating accommodated with in its 3.0-metre wheelbase. Other key dimensions are: length – 4674mm, width – 1826mm, height 1220mm, front and tracks – 1575mm.
Several examples of the chassis were available for inspection, a complex bird-cage fabrication of box sections and square and hollow tubes, rigorously triangulated and braced, and possibly owing more to the Clyde shipyards than the ‘add lightness’ philosophy of Colin Chapman.
The weight of the completed cars was around 30cwt (1500kg). Not particularly heavy by the standards of today’s bloated hatchbacks, but comparable with the Rover SD1. The reason for the over-engineering was a design intent for the cars to last 20-30 years – ‘protecting the initial investment of the discerning’ is how the 1983 sales brochure puts it.
Thoughtfully-designed independent suspension
Suspension is double wishbones all round, the rear system following racing practice with wide-based purpose built wishbones and the facility for adjustment of the geometry which never required to be used. At the front there’s a modified proprietary sub-frame with rack and pinion steering. Bob Henderson is occasionally given to mischievous reticence and wouldn’t reveal its origins.
In the Argyll’s various iterations the spare wheel and fuel tank positions were varied to achieve as near to a perfect 50/50 weight distribution as feasible. The steering column is from a Dolomite, the Marina door handles of the prototype gave way to Volvo fitments, and that windscreen is another Henderson Guessing Game.
The 1976 CAR article, by one Jim Dunn, praised the turbocharged Rover-engined prototype’s performance, its controllability, neutral handling and unexpectedly comfortable ride, but the interior trim was described as, ‘virtually non-existent… Henderson wants the customers to have them detailed to their own requirements elsewhere’.
Avon Coachworks-produced interior
In the years which followed, Avon Coachwork of Leamington Spa were engaged to produce a suitably luxurious interior. The use of Scottish leather partly compensated for this being one of the few areas of specialist input sourced outside west-central Scotland.
As a matter of record, the CAR article refers to a Saab engine option, also turbocharged, but none was ever made. In 1976, this would have been a turbocharged Saab engine, not a Saab Turbo engine, production examples of which were still over a year away.
Bob Henderson has been prescient throughout his career – his 1974 book ‘Theory and practice of turbocharging and supercharging’ appears to have been the first generally published work on turbocharging written outwith the United States.
Launching the Argyll Turbo GT
In October 1983, an official launch for the Argyll Turbo GT took place at Inveraray Castle. A number of advance orders were already in place, production capacity was stated at 12 cars per year, and the first customer car was being readied for delivery. A price range of £25,000 to £30,000 was quoted. At that time a Lotus Esprit Turbo cost £18,913, a Porsche 911 Carrera £21,464, and a Ferrari 308GTB quattrovalvole £26,181.
The production car remained close in principle to the 1976 prototype, the major change being the adoption of a blueprinted and turbocharged version of the Douvrin V6 from the Renault 30, along with its own transaxle, as the core engine, and refinement of internal and external detailing.
The sales brochure lists an alternative 3.5 – 4.2 litre turbocharged ohv V8, no manufacturer is named but it was clearly Rover-derived. In this specification the ZF transaxle, shared with the Maserati Bora and De Tomaso Pantera would be used and the rear seating was omitted.
Mystery surrounds production and power
Bob Henderson told me at the outset that the two things he never discusses are power outputs and production numbers. I fully respect his reticence on this – each Argyll produced was a bespoke product with a customer to manufacturer relationship more akin to the creation of luxury yachts than to the norms of the motor trade.
What is certain is that a steady flow of Argylls left Minnow House over the following seven or eight years. No Rover-engined customer cars were ever produced, but some were made with the Lancia Beta engine and transmission in place of the Douvrin powertrain.
The most intriguing development came when Argyll managed to secure a small batch of Buick V6-based engines, intended for Indy Car racing but never fielded in competition. With specially cast ‘Argyll Turbo GT” cam covers, and extensive re-working for road use, these engines were used in a small run of production cars, once again using the ZF transaxle, while providing 2+2 seating, albeit rather diminished by the space for the bulkier power unit.
Argyll? Still going…
And the final Argyll? Still some way off it seems. Bob Henderson’s to do-list includes completing the final Indy-engined car, its chassis presently sitting in the workshop. He hints at the possibility of further cars – the production infrastructure remains largely in place and the latent demand exists.
I said my farewells, and made my way down the A83, trying in my mind to sum up this enigmatic and idiosyncratic car. I’d hoped to identify some numbers and a timeline, but it was clear that this information was going to remain with the Argyll’s creator. No matter – some terrible cars were produced in their millions, some of the most memorable and influential were one-offs.
With some form of written record of my findings in mind, I endeavoured to pinpoint the Argyll’s identity. Labelling it as a Caledonian Ferrari or Porsche was crass and lazy. Another thought was the ‘Anti-DeLorean‘…
Comparing it with DeLorean
The parallels are intriguing. The two cars used the same engine, the Argyll was introduced for public sale just as DeLorean production came to an ignominious end at a production base very different from Minnow House, but fewer than a hundred miles distant. Where they differed was in design principles and ambition.
The DeLorean was compromised by its emission equipment strangled rear-mounted engine, the high level weight penalty of its gull-wing doors, and various untried technologies.
The company’s estimates of demand were wildly over-ambitious, and the squandering of UK Government funding became an international scandal.
Argyll Turbo GT: engineered in principles…
The Argyll design was founded on sound engineering principles, refined in competition and enhanced by the ingenuity of its creator. Production projections were always modest, and the 1983 launch coverage reported that: ‘Astonishingly, the entire project has been privately financed, and has been neither aided nor funded by the Highlands and Islands Development Board, or any other government agency to date.’ Bob Henderson had earlier that day noted with pride that this remained the case.
The Designer’s aeronautical engineering background, the uncompromised application of well-understood engineering and aerodynamic principles, the disregard for fashion or change for change’s sake, brought a different idea to mind. Look beyond the mid-engined configuration, and the Argyll could be summed up as Scotland’s Bristol.
And then I thought of the title of LJK Setright’s late-career ‘A–ccount of the Bristol’ – ‘A Private Car‘. An inspired and succinct epithet for Setright’s subject, it seems many times more true of the Argyll.
