caption_attribution_description: Riley 1½ RME saloon (DVLA) first registered 29 July 1953, 1496cc Grampian Transport Museum, Alford Aberdeenshire, 24th July 2011.
context_page_description: The Riley RM Series is an executive car which was produced by Riley from 1945 to 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.
  There were three types of RM vehicles produced. All used Riley engines with four cylinders in-line, hemispherical combustion chambers and twin camshafts mounted high at the sides of the cylinder block.
  The RMA was a large saloon, and was replaced by the RME. Both used a 1.5 L 12 hp, developed before WWII.
  The RMB was a longer car: it was replaced by the RMF. Both cars used a larger engine, new in 1937, a 2.5 L 16 hp "Big Four".
  The RMC and RMD were limited-production cars, an open 2 or 3-seater Roadster and a 4-seater Drophead.
context_section_description: Released in 1952, the RME was an improved RMA.  It still used the 1.5 L four and featured a fully hydraulic braking system. The body had an enlarged rear window with curved glass. To improve acceleration the rear axle ratio was changed from 4.89:1 to 5.125:1.
  When the 2.5 L (2443 cc) car ended production in October 1953 a switch to no running boards was amongst many updates to the RME including wholly new shaped front mudguards.
  Produced from 1952, it was discontinued in 1955 and ultimately its place in the range went in 1957 to the much shorter and unrelated, intended but unused, replacement for the Morris Minor — Riley One-Point-Five also sold as Wolseley 1500, Morris Major and the Austin Lancer.
  An RME tested by The Motor magazine in 1952 had a top speed of 75 mph (121 km/h) and could accelerate from 0–60 mph (97 km/h) in 29.5 seconds. A fuel consumption of 24.2 miles per imperial gallon (11.7 L/100 km; 20.2 mpg‑US) was recorded. The test car cost £1,339 including taxes.
