An R-S version of the XF was confirmed in 2012 following on from a picture that Jaguar released shortly before the Los Angeles Motor Show. It uses the same 5.0-litre supercharged V8 engine as the XKR.
The engine produces 550 PS (400 kW) and 680 N·m (500 lbf·ft) of torque. The XFR-S has an electronically limited top speed of 300 km/h and does 0-60 mph in 4.4 seconds. The XFR-S differs from the normal XFR as it has bespoke 20-inch Varuna-design alloy wheels, wider front grills and carbon fibre. The front grills improve aerodynamic efficiency as does the large rear wing. Combined, they cut lift by 68%. At the back there is a rear diffuser and quad tailpipes. The suspension is stiffer by 30% and the electronic differential and stability control are reprogrammed to take the extra power.
