The 1987-1994 Jaguar XJ6, the oft-postponed successor to the original XJ sedan line, was developed as Project XJ40. It was introduced to Europe in 1986, as a 1988 U.S. model in early 1987.

Basically the same successful concept with squarer styling; simplified design for more consistent, higher-quality assembly; standard antilock brakes; and a wholly new drivetrain. The last combined the "AJ6" 3.6-liter 24-valve inline six (first test-marketed in the European XJ-S) and a new four-speed ZF automatic transmission with a unique "J-gate" selector providing manual-override capability.

As quiet and smooth-riding as any previous XJ6, but lackluster performance prompted higher compression for 1988, producing small gains in horsepower and torque. Performance further improved via a stroked 4.0-liter replacement for 1990, when a revamped instrument panel appeared with analog minor gauges instead of vacuum-fluorescent bar-graphs.

Always sold in America in base and ritzy Vanden Plas forms, joined for 1990 by an in-between Sovereign model with Euro-style square headlamps (also applied to the V-P) and a new top-line Majestic with Daimler-style fluted grille. European offerings included 2.9- and later 3.4-liter entry-level models (with available with manual transmission) as well as derivative Daimlers, but there would be no new-generation XJ12 until 1993. Reason: the XJ40 was deliberately designed not to accept the Jaguar V-12, one result of a political dispute during the waning days of Leyland ownership.
