sell to a cautious public. So, the Minor name, intended for the midsized model in Thomas' planned trio of new cars, was adopted for what would become the smallest postwar Morris. The original 1928 Morris Minor had itself introduced a number of innovative features and had been the first four-wheeled car to sell for £100. The new Morris Minor was launched at the British Motor Show at Earls Court in London on 27 October 1948. The original range consisted solely of a two-door saloon or a two-door tourer with a 918-cc engine and a starting price of £358. At the same show, Morris also launched the new Morris Oxford and Morris Six models, plus Wolseley variants of both cars, which were scaled-up versions of the new Minor, incorporating all the same features and designed with Issigonis' input under Oak's supervision. Thus, Issigonis' ideas and design principles underpinned the complete postwar Morris and Wolseley car ranges, although not the same extent that Miles Thomas had initially proposed. Minor ‘Series MM’ The Series MM type Minor was produced from late 1948 until early 1953. It included a pair of four-seat saloons, two-door and (from 1950) a four-door, and a convertible four-seat Tourer. The front torsion bar suspension shared its design with the larger Morris Oxford MO, as was the almost-unibody construction. Although the Minor was originally designed to accept a flat-4 engine, late in the development stage it was replaced by a side-valve inline-four engine, little changed from that fitted in the early 1930s Morris Minor and Morris 8, with a bore of 57 mm but with the stroke of 90 mm and not 83 mm, and producing and of torque. The engine pushed the Minor to just but delivered . Brakes were four-wheel drums. Early cars had a painted section in the centre of the bumpers to cover the widening of the production car from the prototypes. This widening of is also visible in the creases in the bonnet. Exports to the United States began in 1949 with the headlamps removed from within the grille surround to be mounted higher on the wings to meet local safety requirements. In 1950 a four-door version was released, initially available only for export, and featuring from the start the headlamps faired into the wings rather than set lower down on either side of the grille. The raised headlight position became standard on all Minors
