Morgan 4/4 was the Morgan Motor Company's first car with four wheels. It appeared in 1936. Its model designation "4-4" (later "4/4") stood for four wheels and four cylinders. Earlier Morgans had been three-wheelers, only, typically with V-twin engines. Apart from a break during World War II (and the period March 1951 to September 1955) the 4/4 has been in continuous production from its debut right up to the present day. Engine capacity has increased from the 1,122 cc Coventry Climax engine in 1936 to a 1.8-litre Ford engine in 2004, although it is currently back down to 1,595 cc.
The Series II, now the 4/4 rather than the 4-4, was introduced in 1955 with 386 built by October 1960. Although very similar in appearance to the old 4-4 it was virtually a new car with a chassis based on the one used in the Morgan Plus 4. The traditional independent front suspension using sliding pillars and coil springs was fitted with a rigid axle and semi-elliptic leaf springs at the rear. Disc wheels were fitted as standard items.
A side-valve 1,172 cc Ford 100E engine was used with a Ford three-speed gearbox. The engine produced 36 bhp. Hydraulic brakes with 9 in (229 mm) drums were fitted. It was also available in 40 bhp (30 kW; 41 PS) 'Competition' form with Aquaplane head conversion, twin S.U. carburettors, and an improved gearshift linkage.
Inside there was a bench seat back and individual squabs covered in PVC, with leather as an option, and rubber floor covering. A heater was available as an option as was a rev counter and more surprisingly, direction indicators.
In 1956 The Motor magazine tested a Series II and recorded a top speed of 75.3 mph (121.2 km/h), acceleration from 0-60 mph (97 km/h) in 26.9 seconds and a fuel consumption of 35.1 miles per imperial gallon (8.0 L/100 km; 29.2 mpg-US).
