Beginning in the early 1980s, both Ford and General Motors began to make optionally available diesel engines with their full-sized pickup trucks. The Chrysler Corporation followed suit in 1989 when the automaker contracted with Cummins to supply diesel engines for its Dodge Ram pickup truck line. That first engine was a 5.9L I6 utilizing direct injection.
