Truck Moving

Although it had been invented in 1897, the diesel engine did not appear in production trucks until Benz introduced it in 1923.[5] The diesel engine was not common in trucks in Europe until the 1930s. In the United States, Autocar introduced diesel engines for heavy applications in the mid-1930s. Demand was high enough that Autocar launched the "DC" model (diesel conventional) in 1939.
