Many people who visited the London Motor Show in October 1959 met an unfamiliar sight at the stand of Austin and Morris of the British Motor Company. It had a strange styling which was quite different from the current cars at that time; however most thought it was cute. They could not quite believe that this car could seat comfortably, four large British gentlemen or stout women, in a car that had a length of 3.05m and a width of 1.41m. If they had known the amount of time and trouble that the designers had taken to accomplish this feat, they would have better understood why this was not only practical, but feasible as well.

Prior to the release of the Austin seven and the Morris Mini Minor, the Austin A40, designed by Pininfarina of Italy had been successful in using the 2 box styling. This same design styling was adopted for the Mini Cooper. A front wheel drive was selected to keep the floor paneling level flat. A small powerful engine was selected and developed to be mounted sideways, in front, and driving the small diameter 10" wheels, which were laid out at the four corners of the body.
