Jaguar today announced the introduction of the fourth and newest member of its acclaimed XF lineup, the 2010 XF Supercharged sedan. Joining the 4.2L and 5.0L naturally aspirated models and the range-topping XFR super-saloon in the U.S. market, the new XF Supercharged comes with a 5.0L force-fed engine pumping out a 470hp (351kW) and 424lb-ft (574Nm) of torque - a 12% increase in power over the 4.2L 2009 Jaguar XF Supercharged.

This bump in output is courtesy of the new 5.0-liter supercharged AJ-V8 Gen III engine that debuted at this year's Detroit Auto Show. However, it’s not just about more power. The new XF Supercharged also gets Jaguar’s latest ‘Adaptive Dynamics’ variable suspension damping system and the ‘Active Differential Control’ electronically controlled rear differential as standard.

The end result is a 0-60mph time of 4.9 seconds – just 0.2 seconds off the pace of the 510hp (380kW) XFR.

Other features include uprated ventilated disc brakes, 20in wheels, contrasting color twin needle stitching on the instrument panel and door top rolls, a unique Rich Oak veneer, a 440W Bowers & Wilkins surround sound system, HD radio, and a heated steering wheel.

The XF Supercharged will go on sale this October and will be priced from $68,000. As for the rest of the lineup, the 300hp (225kW) 4.2L naturally aspirated XF is priced from $52,000, the 385hp (287kW) 5.0L naturally aspirated XF Premium at $57,000 and the aforementioned XFR at $80,000.

Sadly, we Americans still miss out on one other XF variant, the XF Diesel S. This super frugal sedan is limited to European markets and is powered by a 3.0L commonrail turbodiesel returning 34.5mpg (6.8L/100km) in fuel economy.
