2008 Jaguar XJ

The aluminum chassis remains, of course, as does the same engine lineup as the current model. AutoWeek, however, reports that the XJ will share its future engine lineup with the upcoming XF sedan. We've learned already that the XF will feature an intriguing engine lineup that includes a base 4.2L V8, a supercharged 4.2L V8 producing 420 hp and a supercharged 5.0L V8 producing around 500 hp in the range-topping R-badged models. So we can expect all three engines for the fully redesigned 2010 XJ, as well.
