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 k W) at 5000 rpm by fitting a high efficiency "hot-spot"

manifold

and downdraught

SU carburettor , as well as having slightly higher compression. [5]

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. [5]

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. [6]

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. [7]

These changes seem to have improved the handling. [5]

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. [8]

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.

Prewar For 1946 the engine was moved forward leaving more passenger space Postwar Singer 9 Roadster series 4 A 1949-1950

The Roadster was updated to the 1950

4 A

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. [9]

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. [9]

The bumpers on the 4 A are slightly larger, stronger, and rounded towards the tips. Singer 9 Roadster series 4 AB and 4 AC 1950-1953

By October 1950 the further improved 4 AB Roadster appeared. While superficially similar, this has an independent front

suspension

by coil springs and a hybrid, "hydro-mechanical" brake system by

Girling . Externally, there is a shortened bonnet and disc wheels, as well as fixed sides to the bonnet. The fenders were also redesigned, becoming curvier and deeper. [10]

The steering box also received alterations, mainly aimed at centering it in the chassis so as to simplify manufacturing alternately right-hand or left-hand driven examples. The 4 AB continued in production alongside the larger 4 AD until January 1953.

The prototype 4 AC (built in about a dozen examples) used a slightly larger 1194 cc engine. This was a down-sleeved version of the 1.5 litre version as fitted to the

Singer SM 1500 , and part of an attempt rationalize Singer's lineup. [11]
