The Mini Stylie

athens,

The Mini is a small car that was produced by the British Motor Corporation (BMC) and its successors from 1959 until 2000. The original is considered an icon of the 1960s and its space-saving front-wheel-drive layout (that allowed 80% of the area of the car's floorpan to be used for passengers and luggage) influenced a generation of car-makers.

 

The Mini has won many awards over the years, perhaps the most notable include: "Car of the Century" (Autocar magazine 1995), "Number One Classic Car of All Time" (Classic & Sports Car magazine 1996) and "European Car of the Century" in a worldwide Internet poll run by the prestigious Global Automotive Elections Foundation in 1999. The Mini managed second place (behind the Model T Ford) for "Global Car of the Century" in that same poll.

 

This distinctive two-door car was designed for BMC by Sir Alec Issigonis. Designed as project ADO15 (Austin Drawing Office project number 15), the Mini came about because of a fuel shortage caused by the 1956 Suez Crisis.[11] Petrol was once again rationed in the UK, sales of large cars slumped, the market for German Bubble cars boomed. Leonard Lord, the somewhat autocratic head of BMC, reportedly decreed: 'God damn these bloody awful Bubble Cars. We must drive them off the road by designing a proper miniature car'. He laid down some basic design requirements: the car should be contained within a box that measured 10 × 4 × 4 ft (3 × 1.2 × 1.2 m); and the passenger accommodation should occupy 6 ft (1.8 m) of the 10 ft (3 m) length; and the engine, for reasons of cost, should be an existing unit. Issigonis, who had been working for Alvis, had been recruited back to BMC in 1955 and, with his skills in designing small cars, was a natural for the task. The team that designed the Mini was remarkably small: as well as Issigonis, there was Jack Daniels (who had worked with him on the Morris Minor), Chris Kingham (who had been with him at Alvis), two engineering students and four draughtsmen. Together, by October 1957, they had designed and built the original prototype, which was affectionately named 'The Orange Box' because of its colour.

 

The ADO15 used a conventional BMC A-Series four-cylinder water-cooled engine, but departed from tradition by mounting it transversely, with the engine-oil-lubricated, four-speed transmission in the sump, and by employing front-wheel drive. Almost all small front-wheel-drive cars developed since have used a similar configuration. The radiator was mounted at the left side of the car so that the engine-mounted fan could be retained, but with reversed pitch so that it blew air into the natural low pressure area under the front wing. This location saved precious vehicle length, but had the disadvantage of feeding the radiator with air that had been heated by passing over the engine.

 

The suspension system, designed by Issigonis' friend Dr. Alex Moulton at Moulton Developments Limited, used compact rubber cones instead of conventional springs. This ingenious space-saving design also featured rising progressive rate springing of the cones, and provided some natural damping force. Built into the subframes, the rubber cone system gave a raw and bumpy ride which was accentuated by the woven-webbing seats, but the rigidity of the rubber cones, together with the wheels being pushed out to the corners of the car, gave the Mini go kart-like handling that would become famous.

 

Initially an interconnected fluid system was planned — similar to the one which Alec Issigonis and Alex Moulton were working on in the mid-1950s at Alvis. They had assessed the mechanically interconnected Citroen 2CV suspension at that time (according to an interview by Moulton with CAR magazine in the late 1990s), which inspired the design of the Hydrolastic suspension system for the Mini and Austin 1100, to try to keep the benefits of the 2CV system (ride comfort, body levelling, keeping the roadwheel under good control and the tyre in contact with the road), but with added roll stiffness that the 2CV was very much lacking. The short development time of the car meant this was not ready in time for the Mini's launch. The system intended for the Mini was further developed and the hydrolastic system and was first used on the Austin 1100, launched in 1962, with the Mini following two years later. Ten-inch (254 mm) wheels were specified, so new tyres needed to be developed, the initial contract going to Dunlop. Issigonis went to Dunlop stating that he wanted even smaller, 8 in (203 mm) wheels (even though he had already settled on ten-inch). An agreement was made on the ten-inch size, after Dunlop choked on the eight-inch proposition.

 

Sliding windows allowed storage pockets in the hollow doors; reportedly Issigonis sized them fit a bottle of Gordon's Gin. The boot lid was designed with the hinges at the bottom so that the car could be driven with it open to increase luggage space. On early cars the number plate was hinged so it swung down to remain visible when the boot lid was open. This design was later discontinued as it was discovered that exhaust gases could leak into the cockpit while the boot was open.

 

The Mini was designed as a monocoque shell with welded seams that are visible on the outside of the car running down the A and C pillars, and between the body and the floor pan showing where the joins are. To further simplify construction, the car had external door and boot hinges.

 

All of these novel and elegant technical innovations resulted in a car with minimum overall dimensions yet maximised space for both passengers and luggage.

 

Production models differed from the prototype by the addition of front and rear subframes to the unibody to take the suspension loads, and by turning the engine around with the carburettor at the back rather than at the front. This required an extra gear to be placed between engine and transmission to reverse the engine direction. Making this a reduction gear had the beneficial effect of reducing loads on the gearbox and preventing the rapid wear on the synchromesh which had been a problem on early prototypes. Having the carburettor at the rear helped to reduce carburettor icing, but did expose the distributor to water coming in through the grille. The engine size was reduced from 948 cc to 848 cc, which reduced the top speed from an unprecedented 90 mph (145 km/h) to a more manageable (for the time) 72 mph (116 km/h), as well as reducing cabin noise quite a bit. This decision was reversed in 1967.

 

Despite its utilitarian origins, the classic Mini shape had become so iconic that by the 1990s, Rover Group — the heirs to BMC — were able to register its design as a trade mark in its own right.

 

 

Issigonis' friend John Cooper, owner of the Cooper Car Company and designer and builder of Formula 1 and rally cars, saw the potential of the Mini for competition. Issigonis was initially reluctant to see the Mini in the role of a performance car, but after John Cooper appealed to BMC management, the two men collaborated to create the Mini Cooper, a nimble, economical and inexpensive car. The Austin Mini Cooper and Morris Mini Cooper debuted in 1961.

 

The original 848 cc engine from the Morris Mini-Minor was increased to 997 cc, boosting power from 34 bhp to 55 bhp (25 to 41 kW). The car featured a racing-tuned engine, twin SU carburettors, a closer-ratio gearbox and front disc brakes, uncommon at the time in a small car. One thousand units of this version were commissioned by management, intended for and designed to meet the homologation rules of Group 2 rally racing. The 997 cc engine was replaced by a shorter stroke 998 cc unit in 1964.

 

A more powerful Mini Cooper, dubbed the "S", was developed in tandem and released in 1963. Featuring a 1071 cc engine and larger servo-assisted disc brakes, 4,030 Cooper S cars were produced and sold until the model was updated in August 1964. Cooper also produced two models specifically for circuit racing, rated at 970 cc and a 1275 cc, both of which were also offered to the public. The smaller-engine model was not well received, and only 963 had been built when the model was discontinued in 1965. The 1275 cc Cooper S models continued in production until 1971.

 

Sales of the Mini Cooper were as follows: 64,000 Mark I Coopers with 997 cc or 998 cc engines; 19,000 Mark I Cooper S with 970 cc, 1071 cc or 1275 cc engines; 16,000 Mark II Coopers with 998 cc engines; 6,300 Mark II Cooper S with 1275 cc engines. There were no Mark III Coopers and just 1,570 Mark III Cooper S's.

 

The Mini Cooper S earned acclaim with Monte Carlo Rally victories in 1964, 1965 and 1967. Minis were initially placed first, second and third in the 1966 rally as well, but were disqualified after a controversial decision by the French judges. The disqualification related to the use of a variable resistance headlamp dimming circuit in place of a dual-filament lamp. It should be noted that the Citroën DS that was eventually awarded first place had illegal white headlamps but escaped disqualification. The driver of the Citroën, Pauli Toivonen, was reluctant to accept the trophy and vowed that he would never race for Citroën again. BMC probably received more publicity from the disqualification than they would have gained from a victory - but had the Mini not been disqualified, it would have been the only car in history to be placed in the top three on the Monte Carlo for six consecutive years.

 

In 1971, the Mini Cooper design was licensed in Italy by Innocenti and in 1973 to Spain by Authi (Automoviles de Turismo Hispano-Ingleses), which began to produce the Innocenti Mini Cooper 1300 and the Authi Mini Cooper 1300, respectively.

 

A new Mini Cooper named the RSP (Rover Special Products) was briefly relaunched in 1990-1991, with slightly lower performance than the 1960s Cooper. It proved so popular that the new Cooper-marked Mini went into full production in late 1991. From 1992, Coopers were fitted with a fuel-injected version of the 1275 cc engine, and in 1997 a multi-point fuel injected engine was introduced, along with a front-mounted radiator and various safety improvements.

Throughout the 1980s and 1990s the British market enjoyed numerous "special editions" of the Mini, which shifted the car from a mass-market item into a fashionable icon. It was this image that perhaps helped the Mini become such an asset for BMW, which later bought the remnants of BMC as the Rover Group. It was even more popular in Japan, where it was seen as a retro-cool icon, and inspired many imitators. The ERA Mini Turbo was particularly popular with Japanese buyers.

In 1994, under Bernd Pischetsrieder, a first cousin once removed of Issigonis, BMW took control of the Rover Group, which included the Mini, fitting an airbag to comply with European legislation.

By March 2000, Rover was still suffering massive losses, and BMW decided to dispose of most of the companies. The sell-off was completed in May that year. MG and Rover went to Phoenix, a new British consortium; and Land Rover was sold to Ford Motor Company. BMW retained the Mini name and the planned new model, granting Rover temporary rights to the brand and allowing it to manufacture and sell the run-out model of the old Mini. By April 2000, the range consisted of four versions: the Mini Classic Seven, the Mini Classic Cooper, the Mini Classic Cooper Sport and — for overseas European markets — the Mini Knightsbridge. The last Mini (a red Cooper Sport) was built on October 4, 2000 and presented to the British Motor Industry Heritage Trust in December of that year.[3] A total of 5,387,862 cars had been manufactured.[18]

After the last of the Mini production had been sold, the 'Mini' name reverted to BMW ownership. The new 'BMW' MINI is technically unrelated to the old car but retains the classic transverse 4-cylinder, front-wheel-drive configuration and iconic "bulldog" stance of the original.

Mark V (from 1984): all cars had 8.4-inch (210 mm) brake discs and plastic wheel arches (mini special arches) but retained the same Mark IV body shell shape. Mark VI (from 1990): the engine mounting points were moved forward to take 1275 cc power units, and includes the HIF carb version, plus the single point fuel injected car which came out in 1991. The 998 cc power units were discontinued. Internal bonnet release were fitted from 1992. Mark VII was the final twin point injection with front mounted radiator.
