Jaguar's biggest sedans get revised styling and a new top-line model for 2006. Base XJ8 and performance XJR models continue on a 119-inch wheelbase. XJ8 L, Vanden Plas, Super V8, and new Super V8 Portfolio use a 124-inch chassis. All models 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 with automatic-adjusting shock absorbers. The XJR has a firmer suspension than other models and unique styling cues. Vanden Plas and Super V8 versions have a more luxurious interior treatment. A DVD entertainment system with a video screen in the back of each front headrest is standard on Super V8, available on XJR. Optional are adaptive cruise control, four-zone automatic climate control, heated front and rear seats, and a navigation system. The Super V8 Portfolio is the first Jaguar sedan priced over $100,000. Portfolio has unique trim, additional leather and wood appointments, and two-passenger rear seating divided by a center console.
