The Alfa Romeo RL was produced between 1922-1927. It was Alfa's first sport model after World War I. The car was designed in 1921 by Giuseppe Merosi. It had a straight-6 engine with overhead valves. Three different versions were made: Normale, Turismo and Sport. The RLTF (Targa Florio) was the race version of RL - it weighed half of normal versions, the engine had seven main bearings instead of four and double carburetors.
