The 2012 XF has been unveiled at the New York Auto Show complete with fresh styling, advanced new technologies and an innovative entry-level powertrain that promises to make it the most efficient Jaguar yet produced.

Key to the changes is a new look for the XF.  Drawing on the latest Jaguar design language applied to the XJ, the new XF features an all-new look to the front end with slim new headlight units set into which are distinctive LED lighting strips sitting either side of a larger, more upright grille.  A lower bonnet line complete with a pronounced, wider power bulge running down the centre lends the XF a purposeful stance emphasised by a new look to the lower bumper section complete with a trio of airdams, the outside pair of which are now intersected by twisted chrome fins. Further back, a pair of subtle new vents are mounted to the front wings complete with Jaguar script set into the chrome strip.  At the rear of the car the tail lamp units have been redesigned with LED technology being employed, while the units themselves now extend further into the boot lid with a new chrome blade sitting below a simple Jaguar leaper badge.

The interior of the XF has been given a subtle refresh with a restyled steering wheel joining revised switchgear for the ventilation systems and all-new colour central and dial-mounted screens relaying reprogrammed navigation and entertainment software.  Redesigned seats offer a new look and greater support while fresh trim finishes ensure the XF’s award-winning interior still sets the benchmark in its class.

Significant changes take place under the skin of the new XF with a four cylinder engine available for the first time. The 2.2-litre common rail diesel unit, installed in a north-south configuration, develops 190 PS and 332 lbs ft of torque and is linked to a new eight-speed ZF automatic gearbox and an innovative Stop-Start system – marking the first time such a device has been fitted to a Jaguar.  The result is combined economy in excess of 50 mpg and CO₂ emissions of 149 g/km. The 3.0-litre V6 diesel engines continue in 240 PS standard and 275 PS Diesel S form while the petrol range comprises of a pair of V8 engines developing 385 PS and, in supercharged XFR form, a substantial 510 PS. High performance Diesel S models benefit from a host of upgrades including full aerodynamic styling, adaptive dynamic suspension (as on XFR) and an ‘R’ performance interior.

Across the new XF range advances have been made in refinement with active engine mounts (diesels) and new sound deadening material featuring on the car as well as redesigned wing mirrorsto reduce wind noise.  The result is a car that sets new benchmarks in the suppression of road noise.

The new XF will go on sale in September with prices starting at £30,950 for the 2.2-litre diesel
