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.
Diesel XFs also get 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 332lb ft 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.
The upshot is a claimed 0-60mph time of 8.0sec, combined economy of 52.3mpg and CO2 emissions of 149g/km.
