In January 1957, the A55 Cambridge was introduced to replace the A50 model. It used the same 1.5 L B-Series engine as its predecessor, though with a higher compression ratio: 51 hp (38 kW) at 4250 rpm was now available.

The Cambridge had been restyled somewhat and now had a larger boot and much larger rear window. The car was also lowered by fitting 13 in (330 mm) road wheels which were smaller than those on the A50 but the overall gearing remained the same by changing the rear axle ratio. Two tone paint was an option.

Just over 150,000 were produced when it was replaced by a new Pininfarina-designed A55 Cambridge for 1959.

Van and pick-up versions based on the pre-"Farina" A55 were introduced in 1957, and remained in production until 1973. From 1962 they were fitted with the 1622cc engine and renamed A60, fitted with a wider grille never seen on the Cambridge car, and also offered under the Morris 1/2 ton name. In their final years the van and pick-up were all designated "Morris", following a decision to remove the Austin badge from British Leyland commercial vehicles.

A de luxe A55 with manumatic transmission was tested by The Motor magazine in 1957 had a top speed of 77.1 mph (124.1 km/h) and could accelerate from 0-60 mph (97 km/h) in 27.0 seconds. A fuel consumption of 31.6 miles per imperial gallon (8.94 L/100 km; 26.3 mpg_-US) was recorded. The test car cost £870 including taxes of £291.
