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.
A fitted suitcase was supplied to take full advantage of the usable space in the luggage compartment.
Performance was handicapped by the use of the Bantam's three speed gearbox and top speed was in the order of 65 mph (105 km/h).

Advertising copy incorporated "from the inspiration of the Le Mans model" though  the Singer sports-racing link remained deliberately muted after the death of 8 spectators  in September 1936's RAC Tourist Trophy on Ireland's Ards Circuit, the Ulster TT.
In that era the TT was a handicap and won by either MG or Riley.
Unlike the Le Mans the Roadster was designed and built so it could be sold at a moderate price.

The makers claimed a top speed of 70 mph (110 km/h) and acceleration: 0 to 30 mph (48 km/h) in 6 seconds and 0 to 50 mph (80 km/h) in 18 seconds.
Standard equipment included a spring steering wheel, concealed  spare wheel, 12-volt electrical system and windscreen wipers.

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 following the war, in 1946, 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 car being popular with the Elite in India and featured in the collections of a few Maharaja's.
