Monday 25th October 1954

The Austin Cambridge A50 was introduced in the United States. With a body identical to that of the A40 Cambridge, it used a new 1.5 litre (1489 cc) B-Series four-cylinder engine with single Zenith carburettor which was good for 50 hp (37 kW). The de luxe version had a heater, leather seat facings, carpets replacing the standard rubber matting, armrests on the doors, twin-tone horns, a passenger sun visor, and some extra chrome including overriders.
Technical advances in the A50 Cambridge included an optional Borg-Warner overdrive unit for the top three (of four) gears. A semi-automatic transmission (branded “manumatic” and providing pedal-free clutch operation) was also offered, but it was unpopular with buyers.
A number of modifications were introduced in October 1956 including smaller 13 in (330 mm) wheels and increased compression ratio (8.3:1).
A de luxe version tested by The Motor magazine in 1955 had a top speed of 73.6 mph (118.4 km/h) and could accelerate from 0–60 mph (97 km/h) in 28.8 seconds. A fuel consumption of 28.0 miles per imperial gallon (10.1 L/100 km; 23.3 mpg-US) was recorded. The test car cost £720 including taxes.
A radio and a clock were optional extras.
