Crossley Motors was a British motor vehicle manufacturer based in Manchester, England. They produced approximately 19,000 high-quality cars from 1904 until 1938, 5,500 buses from 1926 until 1958 and 21,000 goods and military vehicles from 1914 to 1945.

Crossley Brothers, originally manufacturers of textile machinery and rubber processing plant, began the licensed manufacture of the Otto internal combustion engine before 1880. The firm started car production in 1903, building around 650 vehicles in their first year.

The company was originally created as a division of engine builders Crossley Brothers, but from 1910 became a stand-alone company. Although founded as a car maker, they were major suppliers of vehicles to British forces during the First World War, and in the 1920s moved into bus manufacture. With re-armament in the 1930s, car-making was run down, and stopped completely in 1936. During the Second World War output was again concentrated on military vehicles. Bus production resumed in 1945 but no more cars were made. The directors decided in the late 1940s that the company was too small to survive alone and agreed a take over by AEC. Production at the Crossley factories finally stopped in 1958.

Crossley Motors Ltd was first registered on 11 April 1906 (and re-registered with a different company number in 1910) as the vehicle manufacturing arm of Crossley Brothers. The first car was actually built in 1903 and exhibited at the Society of Motor Manufacturers’ Exhibition at Crystal Palace in February 1904, but the parent company saw a future for these new machines and decided a separate company was required.

In 1920 Crossley Motors bought 34,283 (68.5%) of the 50,000 issued shares of the nearby A V Roe and Company – better known as Avro. Crossley took over Avro’s car manufacturing business but Avro continued its aircraft manufacturing operations independently. Crossley had to sell their shares in Avro to Armstrong Siddeley in 1928 to pay for the losses incurred in Willys Overland Crossley.

After the Second World War the directors decided that the company was not large enough to prosper and looked for a partner. This resulted in a take over by Associated Equipment Company (AEC) in 1948. AEC’s parent company changed its name to Associated Commercial Vehicles Ltd and Crossley became a division of this. Production of the Crossley range of vehicles continued at the Stockport plant until 1952. After that date the production was of badge-engineered AEC designs and bus bodywork, until the factory was closed in 1958 and sold in 1959.

Although no longer trading, the company was never formally wound up. In 1969 AEC’s new owner, British Leyland, restarted the company with a new name – Leyland National – and production of single-decker buses recommenced.


Production was originally in the Crossley Brothers factory in Openshaw, Manchester but in 1907 they moved to a nearby site they owned in Napier Street, Gorton, Manchester. (Napier Street was later renamed Crossley Street).

With the steady increase in vehicle production, the limits of the Gorton site were in turn soon reached, and in 1914 a further 48 acre (194,000 m²) site was bought in Heaton Chapel, Stockport which became the Errwood Park Works. Construction of the new factory started in 1915, and although intended to relieve congestion on the old site, it was rapidly given over to war work. The western half of the site, built in 1917, but only managed by Crossley Motors, became National Aircraft Factory No. 2. In 1919, this factory was bought from the government and became the Willys Overland Crossley plant, but was eventually sold to Fairey Aviation in 1934. In 1938, the eastern side became another aircraft factory, this time managed by Fairey, and after the Second World War it became the final home of Crossley Motors. Re-armament work caused the search for more space and in 1938 a factory was opened in Greencroft Mill, Hyde, about 3 miles (4.8 km) east of Errwood Park.

 Preserved Crossley SD42/1 bus with aluminium Schelde bodywork, built shortly after the Second World War 1948 for the Dutch public transport network.

Production of the first cars was on a small scale but from 1909 when a new range was introduced it rapidly built up. In that year the 20 hp was introduced (later called the 20/25) and this was taken up by the British War Office and from 1913 it was ordered for the new Royal Flying Corps (RFC). The outbreak of the First World War resulted in a rapid expansion of the RFC, and by 1918 they had over 6,000 of the vehicles with staff car, tender (light truck), and ambulance bodies.

Crossley 25/30 hp Tenders were utilised by the British Army in Ireland from 1919 until their withdrawal in 1922. The Irish Army continued to use them for troop transport throughout the Civil War period, but they were worked hard and appeared to have received little care: of 454 originally supplied, only 57 were in service by 1926 with a further 66 being overhauled or repaired. The 20/25 model was also the first vehicle to be supplied to London’s Metropolitan Police Flying Squad in 1920, some of which were fitted with radio equipment.

Car production resumed after the First World War and a new model, the 19.6, was launched in 1921 and joined in 1922 by the smaller 2.4 litre 14 hp model that would become the company’s best seller. The 19.6 was replaced by the 2.7 litre 18/50 in 1925 fitted with Crossley’s first six-cylinder engine and this was enlarged in 1927 to 3.2 litres in the 20.9. Crossley were the first British car company to offer a factory fitted car radio in 1933. Although the large cars would continue to be available, a range of small models fitted with Coventry Climax engines was announced in 1931 but sales of the cars slowly declined and the last ones were made in 1937.

By the late 1920s the market for hand-made cars began to disappear and the company moved into the bus market and launched its first model, the Eagle single decker in 1928. Although some double deck bodies were fitted to the Eagle, the Condor launched in 1930 was the first chassis to be designed for double decker bodies. The Condor could also be ordered with a diesel engine, made by Gardner at first, and became the first British double deck bus to be offered with diesel power. The big selling pre-war bus was the Mancunian with first deliveries in 1933. This was available as both a double and single decker.

In addition to cars and buses the company also made goods and military vehicles. At first these were conversions of the car models but starting with the BGT1 in 1923 specialised chassis designs were produced. Two Crossley trucks based on the 25/30 car chassis were from 1924 to 1926 the first vehicles to be driven from Cape Town to Cairo by the Court Treatt expedition. A range of heavy goods vehicles starting with the 1931 diesel-powered 12-ton payload Atlas was announced but only a few were made as the factory was by then gearing up to concentrate on buses and military orders. From 1936 military production was rapidly ramped up with British re-armament at first with “IGL” models but from 1940 with a four-wheel drive “FWD” chassis in both tractor unit and truck form. By 1945 over 10,000 FWDs had been made.

After the Second World War there was a boom in the bus industry as wartime losses needed to be replaced. Crossley won what was then the largest ever British export order for buses with a contract with the Dutch government. By the late 1940s bus orders were decreasing and it became clear that the company was too small to continue as an independent manufacturer and in 1948 they were sold to AEC. The last Crossley chassis was made in 1952, but body production continued at Erwood Park until 1958.

1940 Crosley

 A 1940 Crosley

The Crosley was an automobile manufactured by the Crosley Corporation and later by Crosley Motors Incorporated in the United States intermittently from 1939 to 1952.

 1952 Crosley Super Roadster.

Industrialist Powel Crosley, Jr., of Cincinnati, Ohio, owner of Crosley Broadcasting Corporation and the Cincinnati Reds baseball team, had ambitious plans to build a subcompact car and with the able assistance of his younger, graduate engineer brother Lewis Crosley, developed assembly plants at Richmond, Indiana, and Marion, Indiana. In May 1939, the first car was shown at the Indianapolis Speedway. It was a two-door convertible that weighed under 1,000-pound (454 kg) and sold for US$250. It did not achieve sales success, but in 1941 more body styles were introduced.

The chassis had an 80-inch (2,032 mm) wheelbase using half-elliptic springs with beam axle in front and quarter-elliptic springs in the rear. The power came from a two-cylinder Waukesha air-cooled engine that had the fan as an integral part of the flywheel. The engine was connected with a three-speed transmission and then directly via a torque tube to the rear axle, thus eliminating the need for joints. However, this arrangement was judged unreliable, and conventional universal joints were fitted beginning in 1941.

In 1941, the body styles available were expanded to include two- and four-passenger convertibles, a convertible sedan, a station wagon, a panel truck, a pickup, and two models called “Parkway Delivery” (a mini-panel with no roof over the front seat) and “Covered Wagon” (a convertible pickup truck with a removable back seat). Crosley’s first metal-topped sedan (the Liberty Sedan) was introduced for 1942.

During World War II, the Crosley became attractive because of gasoline rationing and the good mileage it could achieve: 50 miles per US gallon (4.7 L/100 km; 60 mpg-imp). Crosley was the last company to cease production of civilian vehicles in 1942, partly to aid Crosley sales to facilitate fuel conservation, and partly because the War Production Board needed time to determine a use for Crosley’s small factories.

Civilian car production resumed at the Marion facility in 1946 with the new, larger and aerodynamic CC model, designed by the firm of Sundberg & Ferar of Royal Oak, Michigan. (The Richmond facility had been sold during the war years.)

Crosley Farm-O-Road

 Crosley Farm-O-Road

Crosley introduced several “firsts” in the American automobile industry, including the first use of the term ‘Sport Utility‘ in 1948 (albeit on an open model based on the wagon, not a wagon on a truck chassis); first mass-market single overhead camshaft (SOHC) engine in 1946; first slab-sided postwar car, also in 1946; first all steel-bodied wagon in 1947; first American car to be fitted with 4-wheel caliper type disc brakes in the 1949 model year (Chrysler Imperial introduced four-wheel disc brakes as standard equipment on Crown Imperials at the beginning of the 1949 model year, but they were not of the caliper type); and the first American sports car, the Hotshot, in the 1949 model year. 1950 brought the Farm-O-Road model, a 63-inch (1,600 mm) wheelbase utility vehicle predictive of the John Deere Gator and other UTVs.

With 24,871 cars sold, Crosley’s best year was 1948. Sales began to slip in 1949, and adding the Crosley Hotshot and a combination farm tractor-Jeep-like vehicle called the Farm-O-Road in 1950, could not stop the decline. In 1952, only 1522 Crosley vehicles were sold. Production ceased after the July 3rd shift that year, and the plant was sold to the General Tire and Rubber Company. A plan to sell the Crosley auto concern to Nash failed to materialize, when Nash merged with Hudson.(Nash, Club Newsletter 1986, Vol. 1)

Regardless of its short life and small size, the Hotshot is well remembered as a phenomenal sports car within its class. A Hotshot won the 1950 Sam Collier Memorial Sebring Grand Prix of Endurance Six Hours, (averaging a blistering 52 mph) and a Siata 300 fitted with Crosley power won the SCCA’s 12 hour Vero Beach race. Throughout, the 1950s Crosley engines dominated 750 cc sports car racing, winning 10 out of 12 SCCA west-coast races alone.

The original engine is the Waukesha Model 150 Cub Twin, a 580 cc air-cooled L-head opposed twin-cylinder engine built by Waukesha Engines of Waukesha, Wisconsin, and used from 1939 through 1942. It was replaced in 1946 with the CoBra (for “Copper Brazed”), a 724 cc overhead-cam four with a 2.5 in (63.5 mm) bore and 2.25 in (57.2 mm) stroke. That engine in turn was replaced in 1949 by the new and more reliable CIBA (Crosley Cast Iron Block Assembly) engine utilizing five main bearings.

The CoBra (Copper Brazed, also known as “The Mighty Tin”) was originally developed by Lloyd Taylor, of Taylor Engines in California, for military use aboard PT boats and B-17 Flying Fortress bombers. The engine was made from sheet metal rather than cast iron like most other engines. This was done to get a thin, uniform wall thickness and thus avoid the creation of hot spots around the combustion chamber that could ignite the fuel, causing pre-ignition (knocks), which in turn limited the compression ratio. These engines were used mainly to power generators, refrigeration compressors, etc., and were widely praised for their successes in the war effort.

The engine was adopted for automobile use in 1946. It was a small, lightweight engine with single overhead camshaft driven by two sets of bevel gears and a vertical shaft at the front of the block. The unitary block and cylinder head weighed only 14.8 pounds (6.7 kg) dry; complete with all accessories (including the flywheel) weighing only 133 pounds (60 kg). The engine displaced 44 cu in (724 cc) and produced 26.5 hp (20 kW) at 5,400 rpm. Longevity was measured in hours and was strictly controlled by equipment maintenance schedules for the wartime duties, but corrosion became a problem for these engines in civilian service. This problem with these automotive powerplants had tarnished Crosley’s reputation by 1948.

The CIBA (Crosley Cast Iron Block Assembly) was a more traditional and more reliable engine utilizing a cast-iron block. When Crosley Motors, Inc. was sold, the engine was renamed “AeroJet” and production continued. Production of the AeroJet ended in 1955 and the engine rights were sold to Fageol and later to a series of different companies ending in 1972 with the Fisher-Pierce Bearcat 55. Maritime modifications mostly included increasing displacement and converting the engine to operate with a vertical axis.

In Europe the Crosley CIBA would be used to great advantage in 750cc sports car class, eventually maturing to a double overhead camshaft (DOHC) design used in the Bandini 750 sport internazionale as well as Nardi 750LM and Siata Amica.
