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.[1] There were three types of RM vehicles produced. The RMA was a large saloon, and was replaced by the RME. The RMB was a longer car to carry the larger engine and was replaced by the RMF. The RMC and RMD were limited-production cars, an open 2 or 3-seater Roadster and a 4-seater Drophead. All of the RM vehicles featured the pre-war Riley race developed 1.5 L (1496 cc) 12 hp (RAC Rating) or the successful 1937 new 16 hp (RAC Rating) 2.5 L "Big Four" straight-4 engines with hemispherical combustion chambers and twin camshafts mounted high at the sides of the cylinder block."
