The Ram line of pickup trucks, previosly sold as Dodge and from 1981 Dodge Ram pickup trucks, were seperated as its own Chrysler brand, Ram, in 2009.
Dodge started selling pickup trucks in 1921, the 1 1/2 ton with a four-cylinder engine, a 1/2 ton after being acquired by Chrysler in 1929 and a four-wheel drive truck in 1934. The flat-head six Plymouth engine was used in Dodge pickup trucks from 1933-68.
The Power Wagon was a continuation of the four-wheel drive trucks built during World War II and were produced from 1946-68 as a rugged general purpose truck.
The smaller more civilian B Series Dodge pickup trucks were produced from 1948-53, the C Series from 1954-60, the D Series, a large truck with the slant six engine and later V8 engines, was produced in two series, first from 1961-71 and after a redesign, from 1972-1993.
The Cummins turbo charged six-cylinder diesel engine made for commercial equipment such as marine equipment and tractors, became available on the 1989 model heavy duty pickup trucks.
A new updated truck line was introduced in 1993 with the 1994 Dodge Ram 1500. The model had a more aerodynamic body and a design resembling big rigs. The line was updated in 2002 and again in 2009.
