A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process.
The Morris Minor is an economy car produced by British marque Morris Motors between 1948 and 1971. It made its debut at the Earls Court Motor Show, London, in October 1948.

The Riley RM Series is an executive car which was produced by Riley from 1945 until 1955. It was the last model developed independently by Riley prior to the 1952 merger of Riley's still new owner Nuffield, with Austin to form BMC. The RM series was originally produced in Coventry, but in 1949 production moved to the MG works at Abingdon. The RM models were marketed as the Riley 1½ Litre and the Riley 2½ Litre.

The Wolseley 4/50 and similar 6/80 were Wolseley Motors' first post-war automobiles. They were put into production in 1948 and were based on the Morris Oxford MO and the Morris Six MS respectively.

The Wolseley 6/99 and 6/110 were the final large Wolseley cars. Styled by Pininfarina with additions by BMC staff stylists, the basic vehicle was also sold under two of BMC's other marques as the Austin A99 Westminster and Vanden Plas Princess 3-Litre. Production began in 1959 and the cars were updated and renamed for 1961. The Wolseley remained in production as the Wolseley 6/110 through to 1968.

The Morris Isis name was first briefly used by Morris Motors Limited on a 6-cylinder car made from 1929 until 1931. It was resurrected on a new 6-cylinder midsize car from the British Motor Corporation in the 1950s to replace the Morris Six MS.
Rochdale cars were a series of mainly glass fibre bodied British sports cars made by Rochdale Motor Panels and Engineering in Rochdale, Greater Manchester, England between 1948 and 1973. The company is best remembered for the Olympic coupé made between 1959 and 1973.
The MG P-type is a sports car that was produced by MG from 1934 to 1936. This 2-door sports car used an updated version of the Wolseley Motors-designed and made overhead camshaft, crossflow engine, used in the 1928 Morris Minor and previously fitted in the J-type Midget of 1932 to 1934, driving the rear wheels through a four-speed non-synchromesh gearbox. The chassis was a strengthened and slightly longer version of that used in the J-type with suspension by half-elliptic springs all round with rigid front and rear axles. Steering was initially by a Marles Weller and later a Bishop Cam system. The two-seat car had a wheelbase of 87 inches (2210 mm) and a track of 42 in (1,100 mm). Most cars were open two-seaters, but streamlined Airline coupé bodies were also made. The P-type was also available as a four-seater, a car that suffered from a lack of power and poor rear ground clearance. Whereas J, K and L-type MGs differentiated between versions with the use of numbers, with 1 indicating a four-seater and 2 a two-seater, this was not the case with the P-type, and there is no clue to the type in the name.
Morris Cowley was a name given to various cars produced by Morris from 1915 to 1958.

British Motor Corporation (Australia) was a motor manufacturing company formed in Australia in 1954 by the merger of the Austin Motor Company (Australia) and Nuffield (Australia). This followed the merger in 1952 of the Austin Motor Company and the Nuffield Group in the United Kingdom to form the British Motor Corporation. Following further corporate changes in the UK in the late 1960s, BMC Australia was absorbed into the newly established British Leyland Motor Corporation of Australia, the name of which became Leyland Motor Corporation of Australia in 1972, and then JRA Limited in March 1983.
The MG M-type is a sports car that was produced by the MG Cars from April 1929 until 1932. It was sometimes referred to as the 8/33. Launched at the 1928 London Motor Show when the sales of the larger MG saloons was faltering because of the economic climate, the small car brought MG ownership to a new sector of the market and probably saved the company. Early cars were made in the Cowley factory, but from 1930 production had transferred to Abingdon.
