The popular Wrangler sport utility debuted in May 1986 to replace the ancient military-style CJ. A fuel-injected, 2.5-liter 4-cylinder engine was standard on base and low-budget S Wranglers, as well as those with the Islander and Sahara option groups. A carbureted 4.2-liter inline six was optional on all but the S version and standard on the top-of-the-line Laredo. All 6-cylinder Wranglers could get a 3-speed automatic transmission to replace the usual 5-speed manual gearbox. Part-time 4-wheel drive was standard and both soft and hard tops were available. For 1990, soft-top Wranglers got locks for their half-steel doors. Hardtop versions gained a rear wiper/washer.
