Morris Minor MM Tourer

Morris Minor MM Tourer

The Morris Minor MM, launched at the 1948 London Motor Show, was a landmark in automotive design. Created by Alec Issigonis — who would later design the equally revolutionary Mini — the Minor was a small car that drove like a much larger, more expensive machine, thanks to its advanced chassis engineering, aerodynamic bodywork, and rack-and-pinion steering that was virtually unique in the small car class.

Issigonis began designing the Minor — internally codenamed 'Mosquito' — during World War II, sketching his ideas while sheltering from air raids. His vision was radical for a small British car: he wanted to create a vehicle that would handle properly, ride comfortably, and be genuinely pleasant to drive, rather than merely providing cheap transportation. To achieve this, he specified torsion bar independent front suspension — an exotic feature in the late 1940s small car market — and rack-and-pinion steering, which provided a directness and precision that contemporary small cars simply could not match.

The result was a car that stunned the motoring press. When The Motor tested the Minor in 1948, they praised its handling, ride quality, and steering in terms usually reserved for sports cars. The Minor cornered flat, tracked straight on the motorway, and responded to its driver's inputs with an accuracy that made every other small car feel vague and imprecise by comparison. Issigonis had achieved something remarkable: he had made a 918cc economy car that was genuinely enjoyable to drive.

The styling was equally innovative. Issigonis designed a unitary monocoque body with smooth, rounded forms that were aerodynamically efficient and aesthetically appealing. The car's most distinctive feature was its wide body and low bonnet line, which gave it a friendly, approachable appearance that endeared it to generations of owners. Legend has it that Issigonis, dissatisfied with the prototype's narrow look, literally cut the car in half and added four inches to the width — the join line is visible on early cars as the seam running down the centre of the bonnet.

The MM series Tourer was the convertible variant, offering open-air motoring in the Minor's delightful chassis. The fabric hood folded flat for a genuine wind-in-the-hair experience, while the windscreen could be folded flat for a more sporting feel — though at the Minor's modest speeds, this was more about ambience than aerodynamics. The Tourer was popular with younger buyers who appreciated the combination of affordable open-top motoring and the Minor's excellent road manners.

The MM's weakness was its engine. The 918cc side-valve unit was a pre-war design that Morris had been using since 1939. It produced just 27 bhp, which, even in a car weighing under 800 kg, meant performance was decidedly leisurely. The Minor could eventually reach 63 mph if given sufficient time and road, but acceleration was glacial by any standard. Issigonis had originally designed the car around a flat-four engine of his own design, but Lord Nuffield vetoed this on cost grounds, forcing the use of the antiquated side-valve unit.

Despite its lack of straight-line performance, the MM Tourer was and remains an utterly charming automobile. Its exceptional handling meant that it could maintain surprisingly high average speeds on cross-country routes, where its ability to corner at speed more than compensated for its modest engine output. The experience of driving an MM on a winding country road, with the hood down and the little engine buzzing away, remains one of the most pleasurable and affordable experiences in classic motoring.

The MM series was produced from 1948 to 1953, when it was replaced by the Series II with its revised Austin-derived 803cc OHV engine. Approximately 176,000 MM series cars were built across all body styles. Today, the MM is recognized as the most historically significant Minor variant, being the original Issigonis design. Tourers are particularly sought after for their open-air charm and the elegance of the early body style with its split windscreen and low-headlamp front end.
