Alfa Romeo RM

The Alfa Romeo RM was produced between 1923 and 1925, based on the RL model. It was introduced for the first time at the 1923 Paris Motor Show and total production was around 500 cars. The RM had a 2.0 L inline-four engine which produced between 40 and 48 PS. As were most of Alfa Romeo's cars, this was also used in motorsports. Three versions were made: Normal, Sport and Unificato. Sport had a raised compression ratio, and Unificato had longer wheelbase and a slightly bigger engine. The RM's top speed was around 90 km/h (56 mph).
