Fact or Fiction?: Cummins Relationship with Chrysler Began in 1989

That is fiction. Even though engines were produced for Chrysler to support a model-year 1989 launch, the relationship began years before. Beginning in the fall of 1981, the Cummins new-business development group began pitching the B Series engine to Chrysler. Talks continued for four years, and then in April 1985, Chrysler agreed to offer the Cummins 5.9L Turbo Diesel in its Ram pickup.
