History
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,The 1957 changes include the power and wearing qualities of the engine were improved by raising the compression and by the fitting of lead indium big-end bearings,and a full-flow oil filter,whilst the car is lowered by use
of smaller wheels; the effective overall gearing, however, was raised by a change in rear-axle ratio which more than compensated for the alteration in wheel size.though with a higher compression ratio: 51 hp (38 kW) at 4250 rpm was now available.
Inside front seats with new refinements in a comfortable 4-door saloon body. Also the dished two-spoke steering wheel. and the large brake pedal fitted when Manumatic transmission eliminates the clutch pedal.

The Cambridge had been restyled somewhat and now had a larger boot and much larger rear window Inside the car, there is a convenient full-width parcel shelf below the facia board and a lockable cubby hole as well as the the usual rear parcel shelf. 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.capacity for luggage is increased and a deeper door for easy loading below which the spare wheel is placed are new Clips for tools are provided on the shelf above the petrol tank.
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.Option for the automatic two-pedal transmission at an extra cost of £50.
