Three types of RM vehicles were made: The RMA was a large sedan and was later replaced by the RME. The RMB was an even bigger car and was later replaced by the RMF. RMC and RMD were roadsters that were manufactured in limited numbers.

The RM vehicles were equipped with either the 1,496 cm³ engine of the Riley 1 1/2 or the 2,443 cm³ engine of the Riley 2 1/2 - both four-cylinder with two half-height camshafts and hemispherical combustion chambers.
