SPECIFICATIONS

Brief History:
The 4CL ('L' for in line or "Linguette") was conceived by Ernesto Maserati in the beginning of 1937 as necessary to combat the Alfa 158. Ready for testing in January 1939, the 4CL had a new 'square' engine with equal bore and stroke (78x78mm) but with 4 valves per cylinder to generate the required horsepower and retain the versatility of the engine.  Fitted into a frame almost the same as the 6CM the car met with success.  After the war it continued to be the pacesetter and only began to wane when the Alfa's took up two-stage supercharging, which Maserati did not adopt officially until 1947.  In the interim Ernesto was trying to resolve a torsional problem with the frame and began experimenting with tubular frames, which led to the 4CLT.
