The RME was an updated 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 and from 1954 no running boards. To improve acceleration the rear axle ratio was changed from 4.89:1 to 5.125:1.
Produced from 1952, it was discontinued in 1955 and ultimately replaced by the Riley One-Point-Five in 1957.
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.
