Design
In 1938 Germany introduced the law for using low octane fuel and it nearly halted the production of sport-type cars. However, Mercedes-Benz was not prepared to discontinue the production of their highly successful sport-type car model. Thus the engine of W18 experienced another upgrade - this time round it became 85 mm and its volume increased to reach 3405 cm³. The compression was reduced from 6.6 to 6.25, whereas the power and driving speed of previous model was retained. This modified engine known as M142 II was coupled with a redesigned 4-speed gearbox and supplemented with an overdrive gear. This version of Mercedes-Benz 320A with its increased engine volume was manufactured until the course of warfare interfered and halted the production of the model in 1942.References
