The Jaguar XFR-S the fastest XF yet will be revealed at the Los Angeles motor show later this month.
It is the second R-S model in the Jaguar line-up, following on from the XKR-S that was launched in 2011.
The XFR-S is likely to offer the same 5.0-litre V8 engine as the XKR-S, which should produce around 542bhp in the XFR-S. The 0-62mph time should be close to the XKR-S's 4.2 seconds.
Although Jaguar is yet to confirm any details of the XFR-S, it is expected to cost around 85,000. More UK-specific information will be available when the car makes its debut at the LA show on November 28.
The new Range Rover and the Jaguar F-type convertible will also be appearing at the LA show, ahead of their release in December this year and summer 2013, respectively.
