Marque History

The original Roadster was an occasional four-seat, two-door tourer, mostly based on the Bantam saloon with a cheery character. It had Singer’s overhead camshaft, 1074 cc inline-four engine used in the Bantam range but tuned slightly to give 36 hp (27 kW) at 5000 rpm, by fitting a high efficiency “hot-spot” manifold and downdraught SU carburettor, as well as having slightly higher compression.[ For 1940, sliding glass panels replaced the celluloid in the sidescreens, along with other equipment improvements. A chromed front bumper was now standard, as were twin aero screens for use when the windscreen was folded flat to reduce frontal area.

The body was built in the traditional method of aluminium panels fixed to a wooden framework. The suspension used leaf springs and was non independent, with rigid axles front and rear. The brakes were mechanically operated.

The successful Roadster re-appeared in 1946 following the war, with these modifications: non-lubricated rubber shackle bushes, improved seating accommodation provided by moving the engine forward and an improved lid at the rear of the body, providing a flat platform for luggage, these changes seem to have improved the handling. Better engine mounts and other isolations were introduced, providing a smoother ride and lessening maintenance. Cars began to filter out to the dealers in September 1946. Nearly all post war production was exported.

The Roadster was updated to the 1950 4A model in September 1949, by fitting the four speed gearbox from the Singer Hunter. A Solex carburettor replaced the SU used on the previous car, adding one extra horsepower. The driving position was also improved, with easier entry and egress, and the Nine Roadster’s awkward gearchange was ameliorated as the gearbox was moved back. The bumpers on the 4A are slightly larger, stronger, and rounded towards the tips.

The 4AB was in production from 1950 to 1953 with approximately 1,000 being made. It was superseded by the 4AD model which was available until the end of the line in 1955.

BMC A-Series 1275 cc engine.

Austin Motor Company’s small straight-4 automobile engine, the A-Series, is one of the most common in the world. Launched in 1951 with the Austin A30, production lasted until 2000 in the Mini. It used a cast-iron block and cylinder head, and a steel crankshaft with 3 main bearings.

The camshaft ran in the cylinder block, driven by a single-row chain for most applications, and with tappets sliding in the block, accessible through pressed steel side covers for most applications, and with overhead valves operated through rockers. The cylinder head for the overhead-valve version of the A-Series engine was designed by Harry Weslake – a cylinder head specialist famed for his involvement in SS (Jaguar) engines and several F1 title winning engines.

Although a ‘clean sheet’ design the A-Series owed much to established Austin engine design practise, resembling in general design (including the Weslake head) and overall appearance a scaled-down version of the 1200cc overhead-valve engine first seen in the Austin A40 Devon which would form the basis of the later B-Series engine.
