Jaguar has introduced an all-new XJ sedan range for 2011, blending the sleek lines of the brand’s new design language with its latest generation engines and chassis systems. Six model variants include standard and long-wheelbase (XJL) versions, the latter adding an additional five inches of rear legroom.
The XJ’s interior is the most luxurious ever offered in a Jaguar, blending the latest infotainment technology and a wide choice of leather and wood finishes. The all-new 2011 XJ is very much a driver’s car, agile and spirited, but without compromise to comfort. The model range includes the XJ with a naturally aspirated 5.0-liter V8; the XJ Supercharged with a 470-hp supercharged version of the engine, and the limited-production XJ Supersport powered by a 510-hp supercharged version. An XJ Supersport can accelerate from zero to 60 mph in just 4.7 seconds yet is not subject to the Federal “gas guzzler” tax.
The new XJ is based on the next-generation of Jaguar’s lightweight vehicle architecture. Primarily aluminum, but also utilizing magnesium and composite alloys, it yields a significantly lighter and stiffer body structure than one built from steel. The construction technique employs the same aerospace-based riveting and bonding processes refined by Jaguar on the XK models and previous-generation XJ sedans.
All 2011 XJ models are powered by variants of the AJ-V8 Gen III 5.0-liter V8 first introduced on the 2010 XF and XK models. The all-aluminum four-cam Jaguar V8 engines combine high power with high efficiency, thanks to such technologies as spray-guided direct fuel injection and dual independent variable cam timing, plus a variable inlet manifold on the naturally aspirated engine. On the XJ Supercharged and Supersport models, a twin vortex system (TVS) supercharger and twin water-cooled intercoolers are efficiently packaged in the engine’s V8.
