The T9 was a car built by BSA between 1933 and 1939. About 300 T9s were built.
The T9 had the same four cylinder 1075cc engine found in the Three-Wheeler Four. There were a few changes as it now had side valves instead of an overhead camshaft with pushrods. The engine produced 10hp and could propel the car up to 65mph (105kmh).
The car was fitted with a wet multi-plate clutch and a three speed constant-mesh gearbox. Cable operated brakes were fitted on all four wheels from 1936.
The chassis was 7ft 6in long and had independent transverse leaf springs in the front and semi-elliptical springs in the rear.
The car cost £160 when new in 1933.
