First was introduced at the Chicago Auto Show in 1986 as a replacement for the Jeep model (CJ). The Wrangler continued to use the separate body and frame concept as the original jeep, but was actually constructed in a new design. It featured rigid live axles in the front and rear, a fold-flat windshield, and removable doors. The suspension, drivetrain, and interior were copied from the Jeep Cherokee XJ model.

It was refreshed in 1996 and totally redesigned in 2006. Each model was given a new label for each new generation. For example, it was called the Jeep Wrangler YJ during its first incarnation from 1986-1996, TJ in its second generation in 1996-2006, and KJ in its third generation from 2006 to the present.

The first generation Wrangler used three different engines –- the 2.5-liter AMC straight-4 (1987-1995), the 4.2-liter AMC straight-6 (1986-1990) and the 4.0-liter straight-6 (1991-1995).
