Jaguar Reveals the 2012 XF Sedan

The Jaguar XF has undergone a thorough revamp, four years into its life, to help it face up to intense competition from the latest BMW 5-series and Audi A6.
The 2012 XF — which goes into production this July — has been given new front-end styling, tweaks to the rear, extra safety features and changes to the interior, including a new audio system.
The diesel XF also gets a new eight-speed automatic gearbox. But perhaps most important for the sales success of the XF is the arrival of a new four-cylinder diesel engine, which also gets a new stop-start system.
All versions of the new XF, including the XFR super-saloon, feature a new bonnet, wings, headlamps, grille and bumper, and modified rear lights. Adam Hatton, a Jaguar design manager, says the nose graphic of the XFR was intended to “turn up the visual volume and give a purposeful road presence”.
The most important technical aspect of the new XF is the new 2.2-litre AJ-i4D four-cylinder diesel engine, which is expected to account for around 60 per cent of future XF sales. The i4D is adapted from the transversely mounted engine used in the Land Rover Freelander, but Jaguar says the unit has undergone significant changes and improvements in refinement.
With 188bhp and 45.9kgm of torque at just 2000rpm, the i4D unit has had changes to the block and sump, lower piston friction, a new camshaft, a water-cooled turbocharger and extra sound insulation. More sound deadening has been added around the bulkhead and behind the alternator, turbo and starter motor.
Sophisticated computational fluid dynamics calculations have been used to smooth the airflow under the car and around the door mirrors. The result, says Jaguar, is that the XF’s interior refinement is class-leading and as good as the current V6 diesel-engined XF.
Both the i4D and V6D engines are hooked up to a new eight-speed ZF auto ’box, which is fitted with a sophisticated stop-start system. Jaguar says the new transmission offers a much wider spread of ratios than the outgoing six-speed unit, as well as quicker shift times and the ability to engage on multiple downshifts, even from eighth to second.
The stop-start is triggered by the amount of pressure the driver uses on the brake pedal and is designed to restart the engine much more quickly than existing systems. Inside, the XF gets new, more shapely seats and an upgraded audio system with a 30Gb hard drive. Four levels of audio kit will be offered, including a range-topping Bowers & Wilkins Dolby surround system.
Other new features for the refreshed XF include automatic high beam assist, adaptive lighting, automatic hazard lights under hard braking and adaptive cruise control with intelligent braking.
