The limited production Jaguar XKR-S GT will be featured at the Toronto’s Motorexpo starting today at Brookfield Place and First Canadian Place, Toronto. With very limited volume the XKR-S GT promises to be a rare sight on the road and a much sought after car for both the collector and the serious driving enthusiast – worldwide production is planned for just 30 cars, with a limit of only 5 produced for the Canadian market to celebrate 25 years of the R Performance Line. MSRP in Canada will be $179,000.

The XKR-S GT is the ultimate track-ready and street legal version of the XK Coupe which was developed by the Jaguar ETO division, an in-house specialty vehicle group.

The XKR-S GT begins with the high-strength all-aluminum body structure featured on every Jaguar XK. This structure is assembled using aerospace derived aluminum bonding and riveting techniques. The addition of extensive aerodynamic enhancements, suspension changes, and carbon ceramic brakes, endow the XKR-S GT with track-ready performance. A limited production run will see just 30 cars built for North America, with 25 for the United States, and 5 for Canada.

A range of bespoke carbon fiber components all work to maximize the aerodynamic down force. These include an extended front splitter, dive-planes and an elevated rear wing.

Astonishing performance is provided by a supercharged 5 -litre V8 engine, producing 550hp and 502 lb/ft or torque, driving through a six-speed automatic transmission and active electronically controlled rear differential. Combined with the aerodynamic and suspension changes, plus revisions to the traction control system’s calibration, the result is a 0-60mph time of 3.9 seconds.2 Electronically limited top speed is 300 km/h (186mph).

The XKR-S GT will be offered exclusively in Polaris White with black racing stripes, and will feature a Jaguar R-S GT script on its louvered hood. The warm charcoal coloured interior features red accents, and includes 16-way electrically adjustable performance seats finished in soft-grain leather and suede cloth with the Jaguar and R-S GT scripts integrated into the backrests. “Jet” black suede cloth is used for the headliner and steering wheel. Steering wheel mounted paddle shifters are now finished in aluminum and are fitted as standard.

Aerodynamics and chassis

The XKR-S GT features a wrap-around carbon-fiber front splitter which extends forward 2.4-inches (60mm). This splitter initializes the management of airflow around, over and underneath the car. Aggressive carbon-fiber twin dive-planes and wheel arch extensions improve the efficiency of airflow around the car. Under the vehicle, the addition of an aluminum front undertray serves to smooth airflow under the car and enhance engine and brake cooling.

A rear carbon-fiber diffuser ensures the smooth exit of air from underneath the car, while the elevated carbon-fiber rear wing works in combination with the decklid mounted spoiler to maximize rear down force. At its electronically limited top speed of 300 km/h (186mph).2 The XKR-S GT produces 320lb of down force. A completely newbonnet with specially cut louvers serve as an engine cooling aid, and help aerodynamic performance by improving the airflow through the front end of the car.

Allied to the extensive aerodynamic revisions are substantial suspension upgrades. The front and rear suspension arms, uprights, wheel bearings, bushings, and rear subframe are all-new. The overall set-up works to increase lateral suspension stiffness for greater precision and responsiveness.

Integral to the revised suspension system is a new spring and damper module design. The XKR-S GT has a motorsport-derived twin spring system mated to the Jaguar Adaptive Dynamics active damping system – the dampers are now also ride-height adjustable. Front and rear spring rates are 68% and 25% stiffer respectively than on the XKR-S, while the damper tune is much more track-focused, providing increased levels of body control and grip.

The Jaguar Adaptive Dynamics system has been tailored for the XKR-S GT so that the suspension parameters in the selectable “Dynamic Mode” delivers a higher level of body control with enhanced traction and grip.

The XKR-S GT has a front track which is 52 mm (two inches) wider than that of the XKR-S while the rear remains the same. The steering rack features a faster ratio and retuned steering valving. The result is an immediacy of turn-in and crisp response to steering inputs.

Gloss black 20″ forged alloy wheels are shod with Pirelli Corsa performance tires (255/35-20 and 305/30-20 front/rear), giving the XKR-S GT a more muscular stance and greatly increasing its grip and stability.

Brakes

The XKR-S GT is the first production Jaguar to be fitted with a carbon ceramic braking system. The internally ventilated and cross-drilled lightweight brake discs measure 398mm (15.7-inches) and 380mm (15.0-inches) front/rear respectively. Combined with six-piston monoblock front calipers, and four piston rear units — the XKR-S GT delivers extraordinary stopping power and brake pedal feel. The lightweight nature of the carbon ceramic system means a reduction in unsprung weight of 21kg (46.3lbs). The XKR-S GT carbon ceramic braking system also has a longer life span than a standard system. The calipers are painted yellow, and are branded with a ‘Jaguar Carbon Ceramic’ script.

Enhanced braking feel comes courtesy of the electronic Pre-Fill system. Working in conjunction with the car’s DSC system, Pre-Fill subtly pressurizes the brakes every time the driver comes off the throttle pedal, resulting in a very short and consistent level of travel on the brake pedal. This maximizes braking response, reduces the car’s stopping distance and delivers increased levels of confidence during high performance driving.

Performance

An all-aluminum 5-litre supercharged quad-cam V8 engine produces 550hp and 502 lb/ft of torque, and delivers exhilarating performance and efficiency thanks to the technologies such as spray-guided direct injection (SGDI) and dual independent variable cam timing (DIVCT).

The high-pressure die-cast lightweight aluminum block is stiffened with cast-iron liners and cross-bolted main bearing caps, providing refinement to match its power. The engine breathes through aluminum four-valve cylinder heads, with pressurized air supplied by a Roots-type twin vortex supercharger. Two air to liquid intercoolers, which feature their own water-cooling circuit, reduce the temperature of the intake charge to optimize power and efficiency.

The XKR-S GT features a fully active performance exhaust system with valves that open under load to enhance gas-flow, enunciate the car’s aural character, and maximize power output.
