1985-87: Jeep Cherokee XJ, Wagoneer XJ and Comanche MJ
Jeep also got into the diesel economy wars of the mid-1980s. Renault owned 49 percent of AMC/JEEP at the time, so it made sense a well-developed 2.1L Renault intercooled turbo diesel would be used. It was a popular engine in Europe and used in everything from cars and light trucks to vans to motorhomes. It was optional in the Cherokee XJ SUV, Comanche MJ pickup and Wagoneer XJ models through 1987. It was unusual in being turbo-intercooled and was the first intercooled light truck diesel offered in the U.S. It came in front of manual or automatic transmissions. Winnebago offered the compact Le Sharo motorhome in the ’80s and early ’90s powered by this engine. Chrysler dropped the Renault relationship soon after it acquired Jeep in 1987, so the engine left the Jeep stable.
