In spring 1987, the British firm turned out its first new sedan in two decades. Offered in base or elegant Vanden Plas trim, complete with such traditional comforts as fold-down burl walnut picnic tables, the new models rode the same 113-inch wheelbase as before. However, the restyled 4-doors were 3.2 inches shorter, 9.3 inches wider, and 1.5 inches taller. By 1990, a 4.0-liter inline six-cylinder engine and 4-speed automatic transmission was the only powertrain. In addition to the XJ6 and Vanden Plas, the lineup now included a Sovereign sedan and a Vanden Plas Majestic. all had motorized front shoulder belts, manual lap belts, and 4-wheel-disc antilock brakes.
