Austin Cambridge 1954- 1971
The Austin Cambridge (sold as A40, A50, A55, and A60) is a motor car range produced by the Austin Motor Company, in several generations, from September 1954 through to 1969 as cars and to 1971 as light commercials.
It replaced the A40 Somerset and was entirely new, with modern unibody construction. The range had two basic body styles with the A40, A50, and early A55 using a traditional rounded shape and later A55 Mark IIs and A60s using Pininfarina styling.
Note that the A40 number was re-used on a smaller car (the Austin A40 Farina) from 1958 to 1967, and that the Cambridge name had previously been used to designate one of the available body styles on the pre-war 10 hp range.
Initially the Austin Cambridge was only offered with a 4-passenger, 4-door saloon body, although a few pre-production 2-door models were also made. It had a modern body design with integrated wings and a full-width grille. Independent suspension was provided at the front by coil springs and wishbones but a live axle with anti-roll bar was retained at the rear.
A van derivative introduced in November 1956 and a coupé utility (pick up) introduced in May 1957 and remained available until 1974, some 3 years after the demise of the cars on which they had been based.

A 1.2-litre straight-4 pushrod engine B-Series engine based on the one used in the previous Austin Somerset (although sharing no parts) powered the new Austin Cambridge. A maximum power output of 42 bhp (31 kW) was claimed: power was transmitted to the wheels by means of a four-speed gear box controlled with a column-mounted lever.
The A40 Cambridge was intended to be available in both two-door saloon and four-door saloon variants; however, the two-door body style did not reach production.
Only 30,666 A40 Cambridge models were produced. After the A40 Cambridge was dropped early in 1957, the A40 name was re-used on the smaller A40 Farina, though that car, the 'Countryman' version of which was an early example of a hatchback, was neither a replacement nor much related to the A40 Cambridge.

Also introduced in September 1954, and with a body identical to that of the A40 Cambridge, was the A50 Cambridge which 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). It sold better and remained in production through to 1957 with 114,867 A50s being produced
The deluxe 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.
As with its predecessor the A40 Somerset, the A50 Cambridge was built under licence by Nissan in Japan; the arrangement ended in 1959. In total, 20,855 licensed Austin vehicles were produced by Nissan in Japan.

In January 1957, the A55 Cambridge was introduced to replace the A50 model. It used the same 1.5-litre 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.
154,000 were produced when it was replaced by a new Pininfarina-designed A55 Cambridge for 1959.
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 (8.9 L/100 km; 26.3 mpg‑US) was recorded. The test car cost £870 including taxes of £291.
Half-ton commercials
Half-ton commercial models based on the A55 were introduced in 1957. The van was released in February and was followed in May by pick-up, chassis & cab and chassis & scuttle models. Contemporary sales literature used the term Austin ½ Ton Van and Pick-Up.
In October 1962 new models were introduced with a restyled front end, chrome side mouldings, a new front bumper, 14" wheels and various interior refinements. Morris badged van and pick-up models also were now offered. From September 1963 the commercial models were fitted with the 1622cc engine from the Austin A60 saloon, with the Austins still marketed under the Austin ½ Ton name. They remained in production through to 1973.
Australian production
The A55 Cambridge saloon was assembled by BMC Australia and a coupe utility version was designed and assembled by the Sydney-based Pressed Metal Corporation, a subsidary of Larke, Neave and Carter, Austin Distributors.

The A55 Cambridge Mark II, known as the first "Farina" model because of its Pininfarina design, was produced from 1959 through to 1961. It was a rebadgedMorris Oxford and retained the 1.5 litre B-Series engine, now with an SU carburettor, and producing 55 bhp (41 kW) at 4350 rpm.
The interior had individual leather trimmed seats in front spaced closely together to allow a central passenger to be carried. The gear change was either on the column or floor-mounted and the handbrake lever between the driver's seat and the door. Other improvements highlighted at the time included an enlarged luggage compartment with counterbalanced lid and increased elbow width on both front and rear seats. A heater could be fitted as an optional extra.
A "Countryman" estate model appeared in 1960. Austin Cambridge Estates were called "Countryman". (Morris Oxford Estates were called "Traveller".) A55 Mark II and A60 Estates were identical from the windscreen back; the later models never got the reduced rear fins and modified rear lights of the A60 saloons.
The engineering of the car was conventional with coil sprung independent front suspension and a live axle at the rear with semi elliptic leaf springs. The braking used a Girling system with 9 in (229 mm) drums all round.
149,994 were built in total.
A MkII A55 was tested by The Motor magazine in 1959 had a top speed of 75.5 mph (121.5 km/h) and could accelerate from 0–60 mph (97 km/h) in 24.5 seconds. A fuel consumption of 31.0 miles per imperial gallon (9.1 L/100 km; 25.8 mpg‑US) was recorded. The test car cost £878 including taxes of £293.
