Jeep Wrangler

The Jeep Wrangler is a compact and mid-size four-wheel drive off-road vehicle produced by Jeep. The Wrangler was based on a new set of design parameters. Wrangler continued to use a separate body and frame, rigid solid axles both front and rear, a fold-flat windshield, and can be driven without doors. But its suspension, drivetrain, and interior were borrowed from the new Cherokee (XJ) model.

Development of CJ7 replacement was green-lighted in 1982 and was replaced with The Jeep YJ  in 1986. It was an entirely new design with a wider track, slightly less ground clearance, and more comfort. The YJ still had leaf spring suspension similar to that of the CJ. The YJs are easily identifiable due to the rectangular headlights and the fact that the wiper blades rest on the windshield giving this version a distinctive look.

Development of a successor to the YJ began in Chrysler's "Jeep-Truck Engineering Pre-Program" department under Bob Sheaves and TJ program director, Craig Winn in 1990. This updated Wrangler featured a coil-spring suspension for better ride and handling and a return to the classic CJ's round headlamps. The engine is the same 4.0 L AMC 242 Straight-6 used in the Cherokee and Grand Cherokee. A 2.5 L AMC 150 Inline-4 engine was available on entry-level models until 2002 when the 2.4 L DOHC 4-cylinder engine.
