Which Jeep model first used the 1984 XJ platform?

The Jeep Cherokee first used the 1984 XJ platform. The XJ was the second-generation Cherokee, introduced for the 1984 model year as a smaller and lighter replacement for the full-size SJ Cherokee.

American Motors Corporation developed the XJ during a period when buyers and automakers were moving toward more compact, fuel-efficient utility vehicles. Instead of using a conventional separate body and frame, the XJ employed an integrated unibody structure. This reduced weight while preserving useful interior space and contributed to the model’s strong on-road and off-road performance.

The XJ Cherokee was offered in two- and four-door forms and became one of Jeep’s most influential designs. Its engineering also provided the basis for the Jeep Comanche MJ pickup, introduced in 1986. The platform remained in production in various markets long after its American run began.

The Compass, Commander, and Liberty are later Jeep models and did not introduce the 1984 XJ platform. The Cherokee name can also cause confusion because the original Cherokee was the larger SJ model; the question specifically refers to the compact XJ generation.
