Riley 2.5 litre RMB

In 1946 Riley launched its first large post-war saloon, the 2.5 litre RMB. The RMB had a unique 2443cc four cylinder engine which did share its twin cam-shafts with the smaller 1.5 litre RMA produced at the same time. The RMB produced 90bhp in original form (100bhp on later cars) and could easily reach speeds approaching the magic "Ton" (100mph).

The RMB's body was identical to its smaller sister the RMA, although the overall length was slightly longer. As on the RMA the coachwork was of a traditional design featuring a split front screen and a fabric covered roof. Production of all Riley RM saloons switched from Coventry to the MG factory in Abingdon in 1949, indicating the marques importance within the old Nuffield empire.
