The high-performance ‘R’ version of the XF is planned for launch in early 2010 and it’s rumored to sport an all-new supercharged 5.0L V8 developing around the 460bhp mark. Both V8 engines are being designed from the ground up, with only minor basic design concepts being borrowed from the previous AJ-V8 series of engines. The new V8 engines are also expected to filter down into the XK range to give the coupe a serious performance boost.
Lower spec versions of the XF saloon will carry forward with the current six-cylinder engine, but this is expected to be replaced with inline sixes sourced from Volvo. A new 3.2L I6 that has V8-like performance is said to be on the cards.
