The XFR-S - the fastest, most powerful and agile sports saloon Jaguar has ever built - has today made its global debut at the Los Angeles Auto Show.
The second model in Jaguar's ultra-high performance R-S range, the XFR-S joins its XKR-S sibling in the exclusive 300km/h club and is a vivid expression of Jaguar's longstanding and legendary sports saloon lineage.
The 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 award-winning 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.
Electrifying performance is provided by the 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.
Fitted with an eight-speed transmission incorporating Jaguar's 'Quickshift' technology (developed for the F-TYPE), the increase in engine output allows the 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).
Airflow has been carefully managed in order to both allow the engine to operate at peak efficiency and let the car cleave the air cleanly and safely. The resulting body changes have created a distinctively assertive appearance, beginning with the deeper front bumper with its larger lower air intakes, vertical vanes and carbon fibre front splitter.
Deeper sills and unique 'aero-blades' ensure a clean passage of air along the side of the car and on to the deeper rear bumper sides while a carbon fibre rear diffuser between the signature quad tailpipes extends underneath the rear of the XFR-S to reduce lift. It is aided in this by a bootlid mounted spoiler, two designs being available. Overall lift is reduced by 68%.
The unique 20-inch lightweight forged alloy 'Varuna' wheels are wider front and rear and are shod with specially developed Pirelli rubber, giving the XFR-S a more muscular stance and increasing its grip and stability. Allied to this are extensive suspension revisions which serve to increase lateral suspension stiffness by 30% for greater steering precision and responsiveness.
Revisions to both spring rates and the adaptive damper tune increase the feeling of connectivity with the road surface, providing confidence-inspiring handling and a supple, controlled ride. Recalibrated active electronic differential and Dynamic Stability Control settings allow the enthusiastic driver to make the most of the huge potential of the XFR-S.
The car's intent is underlined by the technical palette of materials used on the interior. This includes carbon leather on the seat bolsters and arm rests and a Dark Aluminium fascia, both of which are exclusive to the R-S range. Providing a further unique touch are a choice of contrasting colour stitching and micro-piping which can be matched to the exterior paint scheme.
