BMC ADO16


The BMC ADO16 is a range of small family cars built by the British Motor Corporation and, later, British Leyland. Launched in 1962, it was Britain's best-selling car from 1963 to 1966 and from 1968 to 1971. The ADO16 was marketed under various make and model names; however, the Austin 1100 and Morris 1100 were the most prolific of all the ADO16 variants.
In production for 11 years, British Leyland replaced the 1100 series with the 1971 Morris Marina and 1973 Austin Allegro.

Naming

The ADO16 was marketed under the following make and model names:
In line with BMC's policy at the time, Austin badged versions of the ADO16 were built at Longbridge, whilst Morris and MG versions were assembled at Cowley. However, some were also built in Spain by Authi, in Italy by Innocenti and at the company's own plant in Belgium. It was the basis for locally adapted similar cars manufactured in Australia and South Africa. Various versions including Austin, Morris, MG, Wolseley and Riley were assembled in New Zealand and Malta from CKD kits from 1963 until the final Austin/Morris versions were discontinued in 1974, a year after the launch of its replacement, the Austin Allegro.
The vehicle was launched as the Morris 1100 on 15 August 1962. The range was expanded to include several rebadged versions, including the twin-carburettor MG 1100, the Austin 1100, the Vanden Plas Princess 1100 and finally the Wolseley 1100 and Riley Kestrel. The Morris badged 1100/1300 models were discontinued on the launch of the Morris Marina in 1971, but the Austin and Vanden Plas versions remained in production in the UK until June 1974.
The three-door estate version followed in 1966, called Countryman in the Austin version and Traveller in the Morris one, continuing the established naming scheme. The Austin 1100 Countryman appeared in the Fawlty Towers episode "Gourmet Night", in which the short-tempered owner of Fawlty Towers Basil Fawlty gave it a "damn good thrashing". This episode was first shown in October 1975.
In 1964 the 1100 was Wheels magazine's Car of the Year.
For most of its production life, the ADO16 was Britain's best selling car.

Design and development

The ADO16 was designed by Alec Issigonis. Following his success with the Mini, Issigonis set out to design a larger and more sophisticated car which incorporated more advanced features and innovations. Pininfarina, the Italian styling studio that had worked with BMC before on the Austin A40 Farina, was commissioned to style the car. ADO16 had comparable interior space to the larger Ford Cortina.
In common with the Mini, the ADO16 was designed around the BMC A-Series engine, mounted transversely and driving the front wheels. As well as single piston swinging caliper disc brakes at the front, which were not common on mass-produced cars in the early 1960s, the ADO16 featured a Hydrolastic interconnected fluid suspension system designed by Alex Moulton. The mechanically interconnected Citroen 2CV suspension was assessed in the mid-1950s by Alec Issigonis and Alex Moulton, and was an inspiration in the design of the Hydrolastic suspension system for the Mini and Austin 1100, to try to keep the benefits of the 2CV system, but with added roll stiffness that the 2CV lacked.
BMC engineer Charles Griffin took over development work from Issigonis at the end of the 1950s while Issigonis completed work on the Mini. Griffin ensured the 1100 had high levels of refinement, comfort and presentation. Griffin would later have overall responsibility for the Princess, Metro, Maestro and Montego ranges.
The ADO16 range sold 2.1 million units between 1962 and 1974, more than half of those being sold on the UK home market.
Autocar reports in October 1973, while the car was still in production, that approximately 2,365,420 ADO16s had been produced.

Mark I (1962–1967)

The original Mark I models were distinctive for their use of a Hydrolastic suspension. Marketing material highlighted the spacious cabin when compared to competitor models which in the UK by 1964 included the more conservatively configured Ford Anglia, Vauxhall Viva and BMC's own still popular Morris Minor. Unlike almost all of its competitors, the AD016 featured front-wheel drive instead of the rear-wheel drive.
The Mark I Austin / Morris 1100 was available, initially, only as a four-door saloon. In March 1966 a three-door station wagon became available, badged as the Morris 1100 Traveller or the Austin 1100 Countryman. Domestic market customers looking for a two-door saloon would have to await the arrival in 1967 of the Mark II version, although the two-door 1100 saloon had by now been introduced to certain oversea markets, including the United States where a two-door MG 1100 was offered.
An Automotive Products four-speed automatic transmission was added as an option in November 1965. In order to avoid the serious levels of power loss then typical in small-engined cars with automatic transmission the manufacturers incorporated a new carburettor and a higher compression ratio in the new 1965 automatic transmission cars: indeed a press report of the time found very little power loss in the automatic 1100, though the same report expressed the suspicion that this might in part reflect the unusually high level of power loss resulting from the way in which the installation of the transversely mounted "normal" manual gear box had been engineered.

Engine

At the end of May 1967, BMC announced the fitting of a larger 1275 cc engine to the MG, Riley Kestrel, Vanden Plas and Wolseley variants. The new car combined the 1275 cc engine block already familiar to drivers of newer Mini Cooper S and Austin-Healey Sprite models with the 1100 transmission, its gear ratios remaining unchanged for the larger engine, but the final-drive being significantly more highly geared.
The Mark II versions of the Austin and Morris models were announced, with the larger engine making it into these two makes' UK market ranges in October 1967. An 1100 version of the Mark II continued alongside the larger-engined models.
Unusually for cars at this end of the market, domestic market waiting lists of several months accumulated for the 1300-engined cars during the closing months of 1967 and well into 1968. The manufacturers explained that following the devaluation of the British Pound in the Fall / Autumn of 1967 they were working flat out to satisfy export market demand, but impatient British would-be customers could be reassured that export sales of the 1300s were "going very well". MG, Wolseley, Riley and Vanden Plas variants with the 1300 engines were already available on the home market in very limited quantities, and Austin and Morris versions would begin to be "available here in small quantities in March 1968".
The addition of a larger engined model to the ADO16 range came at a time when most cars of this size were now available with larger engines than the 1100 cc unit which until then had been the only engine available in the whole range. Its key rivals in the 1960s were the Vauxhall Viva and the Ford Anglia. From 1970, it had gained another fresh rival in the form of the HC Viva, and also from a new Rootes Group model, the Hillman Avenger.
On the outside, a slightly wider front grille, extending a little beneath the headlights, and with a fussier detailing, differentiated Austin / Morris Mark IIs from their Mark I predecessors, along with a slightly smoother tail light fitting which also found its way onto the FX4 London taxi of the time. Austin and Morris grilles were again differentiated, the Austin having wavy bars and the Morris straight ones. The 1100 had been introduced with synchromesh on the top three ratios: all synchromesh manual gearboxes were introduced with the 1275 cc models at the end of 1967 and found their way into 1098 cc cars a few months later.
Mark II versions of the MG, Riley, Vanden Plas and Wolseley were introduced in October 1968, at which time Riley abandoned the Kestrel name. The Riley 1300 Mark II was cancelled in July 1969, and signalled the demise of the Riley marque, proving to be a shade of things to come as the 1970s would see British Leyland discontinue the Wolseley marque and sell most of its model ranges under a solitary brand.
At the London Motor Show in October 1969 the manufacturers introduced the Austin / Morris 1300 GT, featuring the same 1275 cc twin carburetter engine as that installed in the MG 1300, but with a black full width grill, a black vinyl roof and a thick black metal strip along the side. This was BMC's answer to the Ford Escort GT and its Vauxhall counterpart. Ride height on the Austin / Morris 1300 GT was fractionally lowered through the reduction of the Hydrolastic fluid pressure from 225 to 205 psi.

Engine

During 1970, despite being fundamentally little changed since the introduction of the Morris 1100 in 1962, the Austin/Morris 1100/1300 retained its position as Britain's top-selling car, with 132,965 vehicles registered as against 123,025 for the Ford Cortina, in that year entering its third incarnation. By the time the two millionth ADO16 was produced, at the end of June 1971, the Morris-badged version of the car had been withdrawn in order to create space in the range and in the showrooms for the Morris Marina. 1970 turned out to be the 1100/1300's last year at the top of the UK charts.

Mark III (1971–1974)

The Mark III models were introduced in September 1971. At the launch of the Morris 1100 in 1962 the manufacturer stated that they intended for the ADO16 models to remain in production for at least ten years, which despite BMC's vicissitudes through the 1960s turned out to be reasonably prescient. The range was gradually reduced, with the MG 1300 dropped in 1971 and the Wolseley 1300 in 1973. The final British ADO16, a Vanden Plas Princess 1300, left the factory on 19 June 1974. British Leyland replaced the ADO16 was replaced variously by the Austin Maxi, the Morris Marina, and the Austin Allegro. The luxury Vanden Plas 1500 version of the Allegro debuted in 1975.
By this time, its original rival, the Ford Cortina, had long since grown larger, putting ADO16 into the small, rather than medium-sized class, which British Leyland was now competing in with the Allegro, Austin Maxi, Morris Marina and Triumph Dolomite, as well as the long-running Austin 1800 saloons. The ADO16's final key rivals were the Ford Escort, Vauxhall Viva and Hillman Avenger. Foreign cars were also becoming increasingly popular on the UK market during the early 1970s, with perhaps the biggest imported rival to the ADO16 being the Datsun Sunny from Japan.

Legacy

As of February 2016 according to DVLA data there were 640 examples that were taxed and on UK roads.
During the Worboys Committee in the 1960s when the British road signage system was being redesigned, the silhouette of the ADO16 was used in many of the new road sign designs which are all still in use.

ADO16 overseas

The car was sold with various names in different markets.
In Spain it was sold as Morris, Austin and MG, starting production in the Pamplona Authi factory in 1966, and evolving by 1972 into the Austin Victoria.
In Denmark the ADO16 bore the Morris Marina name from 1962 to 1972 - the same name as the British-built and better-known range of saloons produced in the British Leyland range from 1971 to 1980. The MG models were sold as the MG Sports Sedan there, as it was in North America from 1962, and was available with a two-door bodyshell that was unavailable in the UK until 1968. The Vanden Plas Princess was briefly the MG Princess 1100 in North America, while that market also saw an unusual two-door Austin 1100. The ADO16 was not a strong seller in the Northern American markets - particularly in the USA where it was by far one of the smallest cars on sale. In the Netherlands the Austin version was sold as the Austin Glider.
The Austin America was sold in the US, Canada and Switzerland between 1968 and 1972. This two-door version of the car featured a 1275 cc engine. Various modifications were made to suit the US market including an "anti-pollution air injection system", a split circuit braking system, rocker switches in place of some of the dashboard mounted knobs, a "hazard warning system" and flush door locks.
The ADO16 also formed the basis of the Australian Morris 1500 sedan, Morris 1300 sedan and Morris Nomad five-door, the Italian Innocenti Morris IM3 and Austin I4 and I5, the more powerful South African Austin, Morris and Wolseley 11/55 and Austin Apache and the Spanish Austin Victoria and the Austin de Luxe of 1974 to 1977, which had a 998 cc engine.
The Austin Apache was produced until 1977, the last of the ADO16 line, ending a production run of 15 years.

BMC 1100 Aerodinamica

In 1967 Pininfarina unveiled at the Turin Motor Show a concept car based on the Landcrab called the BMC 1800 Aerodinamica. The sleek design previewed the Citroen CX by some seven years. The car was evaluated by BMC, and Pininfarina developed a further smaller model based on the BMC ADO16 model, but the design was not taken up by the then merged British Leyland. This was after BMC had investigated a Mini shaped version. The 1800 version was however used by chief engineer Harry Webster and was know within the Austin Morris division as the Yellow Peril.
