Until 1962, the cars appeared as the Austin 850 and Morris 850 in North America and France, and in Denmark as the Austin Partner (until 1964) and Morris Mascot (until 1981). The name Mini was first used domestically by BMC for Austin's version in 1961, when the Austin Seven was rebranded as the Austin Mini, somewhat to the surprise of the Sharps Commercials car company (later known as Bond Cars Ltd) who had been using the name Minicar for their three-wheeled vehicles since 1949. However, legal action was somehow averted, and BMC used the name Mini thereafter.

In 1964, the suspension of the cars was replaced by another Moulton design, the hydrolastic system. The new suspension gave a softer ride but it also increased weight and production cost and, in the minds of many enthusiasts, spoiled the handling characteristics for which the Mini was so famous. In 1971, the original rubber suspension reappeared and was retained for the remaining life of the Mini.

The production version of the Mini was demonstrated to the press in April 1959, and by August several thousand cars had been produced ready for the first sales.

The name Mini did not appear by itself immediately—the first models being marketed under two of BMC's brand names, Austin and Morris. The name Austin Seven (sometimes written as SE7EN in early publicity material) recalled the popular small Austin 7 of the 1920s and 1930s. The other name used until 1967 in the United Kingdom (and in Commonwealth countries such as Australia), Morris Mini-Minor, seems to have been a play on words. The Morris Minor was a well known and successful car, with the word minor being Latin for "smaller" so an abbreviation of the Latin word for "smallest"—minimus—was used for the new even smaller car. It was originally going to be called the Austin Newmarket.

Sliding windows allowed storage pockets in the hollow doors; reportedly Issigonis sized them to fit a bottle of Gordon's Gin. The boot lid was hinged 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 at the top so that it could swing down to remain visible when the boot lid was open. This feature was later discontinued after it was discovered that exhaust gases could leak into the cockpit when the boot was open.

The Mini was designed as a monocoque shell with welded seams visible on the outside of the car running down the A and C pillars, and between the body and the floor pan. To further simplify construction, the hinges for the doors and boot lid were mounted externally.

Production models differed from the prototypes by the addition of front and rear subframes to the unibody to take the suspension loads, and by having the engine mounted the other way round, with the carburettor at the back rather than at the front. This layout required an extra gear between engine and transmission to reverse the direction of rotation at the input to the transmission. Having the carburettor behind the engine reduced carburettor icing, but the distributor was then exposed to water coming in through the grille. The engine size was reduced from 948 cc to 848 cc; this, in conjunction with a small increase in the car's width, cut the top speed from 90 mph (145 km/h) to a more reasonable (for the time) 72 mph (116 km/h).

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

The suspension system, designed by Issigonis's 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. 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 that 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 Morris/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 was first used on the Morris 1100, launched in 1962; the Mini gained the system later in 1964. Ten-inch (254 mm) wheels were specified, so new tyres had 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.

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. 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, except with the transmission usually separately enclosed rather than using the engine oil. 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. It also exposed the entire ignition system to the direct ingress of rainwater through the grille.

A Brief Overview Of The History Of A Classic Mini Cars

A Brief Overview Of The History Of A Classic Mini Cars

Classic Mini CarsPicture of Classic Mini Cars 1

The Mini is a small car that was made 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 vehicle is in some ways considered the British equivalent to its German contemporary, the Volkswagen Beetle, which enjoyed similar popularity in North America. In 1999 the Mini was voted the second most influential car of the 20th Century, behind the Ford Model T.

This distinctive two-door car was designed for BMC by Sir Alec Issigonis. It was manufactured at the Longbridge and Cowley plants in England, the Victoria Park / Zetland British Motor Corporation (Australia) factory in Sydney, Australia, and later also in Spain (Authi), Belgium, Chile, Italy (Innocenti), Portugal, South Africa, Uruguay, Venezuela and Yugoslavia. The Mini Mark I had three major UK updates: the Mark II, the Clubman and the Mark III. Within these was a series of variations including an estate car, a pickup truck, a van and the Mini Moke—a jeep-like buggy. The Mini Cooper and Cooper "S" were sportier versions that were successful as rally cars, winning the Monte Carlo Rally four times from 1964 through to 1967, although in 1966 the Mini was disqualified after the finish, along with six other British entrants, which included the first four cars to finish, under a questionable ruling that the cars had used an illegal combination of headlamps and spotlights. Initially Minis were marketed under the Austin and Morris names, as the Austin Seven and Morris Mini Minor, until Mini became a marque in its own right in 1969. The Mini was again marketed under the Austin name in the 1980s.

The History Of The Classic Mini Cars Part 2

The History Of The Classic Mini Cars

By the millennium, Rover had encountered financial problems and the Mini line was completely taken over by BMW, with Rover's other Marques, MG and Land Rover being sold to Pheonix and Ford respectively. The Mini Cooper continued to be produced by Rover on a temporary basis until the last ever Mini Cooper was produced on October 4 2000 - a red Cooper Sport - which was presented to the British Motor Industry Heritage Trust.

The Mini Cooper was no longer. The Mini Cooper is dead, long live the MINI Cooper. Of course BMW had plans to revamp the Mini, now known as 'MINI', and the Cooper was to be dragged into the new millennium in style.

The MINI Cooper is mechanically and technically unrelated to the original Cooper but bears distinct aesthetic similarities as well as some mechanical ones including front-wheel drive and the transverse four cylinder engine model.

The new Cooper and Cooper S became instant successes, escalated by the remake of the classic film, The Italian Job, which paid homage to the original film and featured three super charged Cooper S's which got the juices flowing of car enthusiast across the globe.

Of course there were purists who did not agree with BMW discounting production of the 'old' Mini and those who criticised the MINI as being a small BMW with no soul or character, but you only have to look at the numbers to see what a success the MINI, and in particular the MINI Cooper has been.

After only six years of production at MINI's Oxford plant, the one millionth MINI was produced, and it remains one of the most prudent cars you can buy as it depreciates at a considerably lesser rate than many other cars.

John Cooper was right to follow his heart and bypass his friend Issigonis in order to push through the production of what is today an iconic motor car.
