Morris Ten Series M 1938-1948

The Morris Ten Series M was introduced in 1938.
It was a completely new car with unitary construction, although the styling was little-changed from the outgoing Series E. The engine was also new, being the 1140cc X-Series with an output of 37 bhp (28 kW) at 4600 rpm. Although an overhead valve engine like the M-Series engine fitted to the previous Ten Series E, the X-Series was a brand new design following the disappointing performance and reliability of M-Series, which was related to the older Morris sidevalve engines. The Series M's X-Series engine had a 'free-flow' eight-port cylinder head and adopted features from contemporary American engines including a pressurised pump-driven cooling system, a fully filtered lubrication system and an automatic tensioner for the camshaft chain. Along with the contemporary Vauxhall 10-4 the Series M was one of the first mass-market British cars to feature an OHV engine and the Morris was praised for the smoothness, efficiency and quiet-running of its engine. The car had a top speed of around 62 miles per hour (100 km/h).. The running gear was otherwise very conventional, even old-fashioned, for the time, with solid axles with longitudinal leaf springs all-round. Plans had been drawn up to provide the unitary-construction Ten with independent front suspension and Rack and pinion steering, but these were shelved due to cost and marketing concerns, although the parts designed for the Series M would appear in the post-war MG Y-type saloon.

Only saloon bodies with optional sun roof were made for the civilian market but a range of pick up bodies were fitted during World War II as one of among many similar products by British manufactures collectively known by the nickname "Tillies". The car was also assembled in India as the Hindustan 10 .

Postwar models can be distinguished from those made before 1940 by a cosmetic change to the radiator grille, the later versions being rounder, faired in to the engine side panels and without the Morris badge at the top.
