For the 2013 model year Jaguar XF, the sleek four-door coupe continues without any alterations to its design, but the major changes will take place underneath the hood.

The executive model's engine lineup is expanded with two new forced induction petrol power plants, namely a 3.0-litre supercharged V6 delivering 335bhp with 450Nm and a Ford-sourced 2.0-litre turbocharged inline-4 with 237bhp and 340Nm of torque.

The 3.0-litre unit replaces the naturally-aspirated 5.0-litre V8 in some markets. The introduction of a 2.0-litre engine for the XF follows the path taken by its main rival, the BMW 528i. The 2.0-litre XF completes the century sprint in 7.5 seconds, about a second faster than both the 2.2-litre Turbodiesel and the 3.0-litre naturally aspirated V6 petrol.

As for the diesel options, the 2.2-litre four-cylinder diesel range is now available in both 161bhp and 197bhp outputs with the latter replacing the existing 187bhp engine. These new power plants complement the existing 3.0-litre V6 Turbodiesel and the Supercharged 5.0-litre V8 petrol. My guess is that Jaguar may phase out the current 3.0-litre V6 petrol unit and replace it with the 2.0 turbo as the outputs of both engines are similar.

In addition to new power plants, Jaguar will be equipping all gasoline and diesel engines across the XF range with its new 8-speed automatic transmission and start/stop system. Not all variants of the new XF will be available in all markets though. Jaguar is expected to release country-specific details on the XF in the coming months.
