Say hello to the new 2014 Jaguar XFR-S, the fastest and most powerful sedan Jaguar have ever produced with some sleek carbon fibre additions.
The Jaguar XFR-S incorporates engineering features from both the XKR-S and the all-new F-Type two-seater sports car to create the most driver-focused, agile and responsive iteration of Jaguar’s XF saloon range. The XFR-S has been developed by Jaguar Land Rover’s specialist ETO division – its bespoke powertrain, chassis and body enhancements enabling it to push the performance boundaries.
The car has a 5.0-litre supercharged V8 petrol engine which now boasts 550PS and 680Nm – up 40PS and 55Nm respectively over its XFR installation. The increases have been achieved through revisions to the engine management system and optimisation of the flow of air both into and out of the engine. The quick shift eight-speed transmission allows the Jaguar XFR-S to accelerate to 60mph in 4.4 seconds (0-100km/h in 4.6 seconds) and on to an electronically limited top speed of 186mph (300km/h).

The new, deeper front bumper incorporates larger lower central and side air intakes – the former framed in carbon fibre – in order to provide adequate airflow into the engine bay. Carbon fibre is also used to form the front splitter at the lower edge of the bumper, the first of a number of aerodynamic changes designed to smooth the passage of the car through the air at very high speeds.
The extended side sills and aeroblade mouldings behind the front wheels serve to create a sharp break-off point between the lower bodywork and the road surface in order to keep the airflow attached to the car’s sides for as long as possible.
The same thinking dictated the deeper side mouldings behind the rear wheels. This extended rear bumper also incorporates a central, carbon fibre diffuser, deeper than the item found on the XFR and which travels further under the rear of the car to reduce lift.
Rear lift is also reduced through the fitment of a bootlid-mounted spoiler to manage the airflow off the top rear surface of the car. Two options are available, both of which have been designed with the aid the dynamics to provide balanced aerodynamics. The larger of the two rear wings is constructed with a carbon fibre aerofoil centre section.
The combined result of the bodywork revisions is a reduction in overall lift of 68%.
