Jaguar faces some very fierce competition in the luxury segment, especially in the area of high-end sedans. Consider that the XJ fights for buyers’ attention, and dollars, among a field that includes the Audi A8, BMW 7 Series, and Mercedes-Benz S-Class. Each of those heavyweights has been updated recently, and to remain relevant the XJ required at least a little tweaking. The powertrains were already competitive, if not class-leading, and the iconic XJ shape could only be messed with so much. As a result, the 2008 XJ arrives with a look that distinguishes it from the 2007 model, and is aimed at maintaining interest in the car until an entirely new version arrives within the next couple of years.
