Jaguar adding second supercharger to XF lineup
Jaguar is all about tradition, which is one reason why its now the black sheep of Ford's Premier Automotive Group, having never even come close to turning a profit while under Blue Oval ownership. Clearly it's time for a change, as sticking with tried and true traditions has gotten the marque nowhere lately. Just as the XF will be shedding any resemblance to the Jaguar's we've come to know, so to will its engine lineup deviate from the one-supercharger rule. In the past, only the high-performance 'R' version of the S-Type, which will become the XF, had a supercharged engine – a 4.2-liter V8 producing 420 hp. That engine will again be used in the XF, but not in the XF-R. Rather, that blown V8 will merely be the top engine in the standard lineup. Later on, around 2010, Autocar expects a new 'R' version with a supercharged 5.0-liter V8 that sports direct injection and will, in our estimation, produce at least 500 horsepower. Jaguar is serious about making the XF competitive, and the XF-R will require at least a half a grand of horsepower to compete with the BMW M5 and the rest of the German super sedans.
