Jaguar has gone outside the box with nearly every aspect of the XF. Its look is fresh and bold. The interior design and technology are anything but retro. Unlike its competitors from Germany, there's no six-cylinder "base" model sold in the U.S. Perhaps trying to focus more beginner buyers toward the updated-for-2008 X-Type, you'll find no fewer than eight cylinders beneath an XF bonnet.
Buy-in begins with the aforementioned 4.2-liter, 300-horsepower V-8. The XF Supercharged ups the ante to the same blown, 4.2-liter, 420-horsepower V-8 currently huffing away in the performance-minded XKR coupe/convertible and XJR sedan. But BMW, Audi, and Mercedes-Benz offer their midsize sport/lux four-doors with 450 to 500 horses. So that's where Jag is headed with the XFR.
Our intel suggests the XFR V-8 will share certain architecture with the current AJV8 engine, but employ, at minimum, a new block able to be sized at 5.0 liters and beyond. Atop that will be supercharging and intercooling. The result should be at least 500 horsepower in blown form, with a 400-or-so-horse, naturally aspirated version to come later, perhaps replacing the current supercharged 4.2. The XFR's transmission will remain the excellent ZF six-speed automatic, with paddle shifters as on the XKR, plus its own unique calibration.
Standard on the XFR will be 20-inch light-alloy wheels and speed-rated rubber, along with the usual cocktail of upgraded brakes, stiffer suspension tuning, a beefier exhaust note, and sportier interior trim. Visuals likely will ape other Jaguar "R" models, meaning a bit less chrome, wire-mesh front grillework, more aggressive front and rear fascias, a rear lip spoiler, and a slightly reduced ride height.
The XFR will show its production face sometime in 2008 as a 2009 model. Pricing has yet to be announced, but it'll be aggressively positioned against the M5 and E63, meaning a predicted base of just under $80,000.
