The more powerful XF Diesel S that delivers an output of 275HP and a massive 600Nm (443 lbs-ft) of torque, accelerates from 0-60mph (96 km/h) in just 5.9 seconds, 1.8 seconds quicker than the 2.7-litre model, while the car's top speed is electronically limited to 155mph (250 km/h). The XF Diesel S has a combined average fuel consumption of 42.0mpg UK or 35mpg US – an improvement on the 2.7-litre diesel of 12 percent – and a CO2 emissions rating of 179g/km.
On the outside, the Diesel S XF is distinguished by a set of newly designed 19-inch wheels, an aerodynamic boot lid spoiler and discreet 'S' badging.
Along with the presentation of the new diesel-powered models, Jaguar said that it has also performed 'significant trim and specification changes' that include the introduction of a new luxurious Portfolio version.
In the UK, pricing of the new XF 3.0-litre diesel model starts from £33,900 while the new 3.0-litre Diesel S starts at £36,900. These new Jaguar XF models will be available in Europe from March 2009.
