1997 Jeep Wrangler specifications

Assembly Plant: Toledo, Ohio; introduced in April, 1996 as a 1997 model

1997 Jeep Wrangler specificationsTwo 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.  The engines had this in common: gasoline powered, liquid-cooled, in-line engines, with cast iron block and head and sequential multiple-port electronic fuel injection. Two overhead valves per cylinder, hydraulic lifters, flat followers. The two engines were closely related.
