Two engines were available: the 2.5 liter four-cylinder developed by AMC and generating 120 hp; and the 4.0 liter inline six-cylinder, also developed by AMC, and generating 181 (or more) horsepower. At launch, the four-cylinder was only available in the base SE model; the 4.0 was in Sport and Sahara. For each model, a manual transmission was standard, and an automatic was optional.
