Jaguar's flagship sedan offers five models: XJ8, XJ8 L, Vanden Plas, Super V8, and the high-performance XJR. XJ8 and XJR have a 119-inch wheelbase. The others use a 124-inch chassis. All have a 4.2-liter V8. The XJ8, XJ8 L, and Vanden Plas have 300 hp. The supercharged XJR and Super V8 have 400. A 6-speed automatic is the only transmission. ABS and traction/antiskid control are standard, as are front side airbags and curtain side airbags. All models also have a load-leveling suspension. The XJR has a firmer suspension than other models and unique styling cues. Vanden Plas and Super V8 versions have more luxurious interior treatment. Options include four-zone automatic climate control and a navigation system.
