Jaguar unveils new diesel engine for upmarket XFJanuary 7th, 2009 - 2:08 pm ICT by IANS
London, Jan 7 (DPA) Tata-owned Jaguar has given the XF luxury saloon a more powerful diesel engine which is said to save fuel at the same time.The 3 litre, six-cylinder turbo diesel unit in the XF Diesel S replaces the current 2.7-litre unit, boosting performance by 33 percent.
Despite the power gain, the bigger engine (275 horsepower) is said to be 12 percent more fuel-efficient and it cuts carbon dioxide emissions by 10 percent to 179 g/km.
The car will feature at the Detroit car show Jan 17-25.
The engine uses an innovative parallel sequential turbocharger system which Jaguar says improves efficiency and reduces fuel consumption.
For most everyday driving, including motorway cruising, a primary turbocharger does all the work.
When the engine revolutions climb above 2,800 rpm, the secondary turbo comes on stream, boosting engine output.
The new XF Diesel S also gets some trim and specification changes to set it apart from other models in the range. These include new 20 inch alloy wheels and a discreet boot lid spoiler.
A new Portfolio version will be added to the XF line-up in 2009, with aluminium wing vents and bespoke leather interiors.
