The Jaguar XF will get a four-cylinder engine for the first time as part of a package of upgrades for 2012. It is a 2.2-litre diesel adapted from that in the Land Rover Freelander and forthcoming Range Rover Evoque. It will help Jaguar double sales of its award-winning executive saloon from September.
The engine has required extensive modification to fit lengthways in the XF Land Rover mounts it transversely. It develops 190bhp and 310lb ft of torque and comes as standard with engine stop-start and an eight-speed automatic gearbox.
The official fuel and CO2 figures are 52.3mpg and 149g/km.
The eight-speed auto will also feature on V6 diesel versions of the XF from September, trimming fuel consumption by 6% to 44.8mpg and cutting CO2 emissions by 10g/km to 169.
The front end of the XF has been reshaped with a new bonnet, bumper, grille and headlamps and there are more minor changes at the sides and rear.
There are measures to make the cabin quieter and new seats, switchgear, instruments and aluminium ornamentation.
An adaptive dynamics package that changes the damping force, throttle sensitivity and gearshift speeds becomes available on the majority of models and automatic high-beam assistance and intelligent cruise control with automatic emergency braking will also be offered. There's also an improved Bowers and Wilkins hi-fi system.

The exterior of the XK coup and convertible have also been refreshed and they will be joined when they go on sale in the autumn by the ultimate version, the 545bhp XKR-S, which was announced at the Geneva motor show in March. As with the XF, there are upgrades to the interior, plus new colour choices.
Both cars were introduced at the New York motor show today.
