If you still find yourself coming up a few seconds short per lap in your Jaguar XKR-S, the British automaker has introduced the XKR-S GT a cat specifically tuned for the racing circuit at the New York Auto Show.

While Jaguar has left the supercharged 5.0-liter V8 unchanged (550 horsepower and 502 pound-feet of torque), it has tuned and tweaked all the items that really make cars go quicker on the track (e.g. suspension, aerodynamics, contact patches, brakes). A once-over reveals upgraded go-fast goodies including a new ventilated hood, extended wheel arch spats, reworked front end with a bespoke front splitter and canards, a massive rear wing, height-adjustable adaptive dampers, active exhaust, carbon-ceramic brakes and sticky Pirelli Corsa tires. Try as we might, the driver in us can't find anything we not to like about this enthusiast-tuned coupe.

Of course all of the upgraded XK goodness doesn't come easy, or cheap. Jaguar will limit North American sales to just 30 units and price each at $174,000. Learn all the juicy details in the official press release below.

"The XKR-S GT is the most extreme iteration of the Jaguar R Brand's performance focus. Utilizing race-car derived technology, all-aluminum construction and an uncompromised approach to aerodynamic efficiency, the result is a car as capable on the track as it is exhilarating on the road."

– Adrian Hallmark, Global Brand Director, Jaguar

(MAHWAH, N.J.) - March 26, 2013 – The XKR-S GT is the ultimate track-ready and street legal version of the XK Coupe. This vehicle 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. Astonishing performance is provided by a supercharged 5 -liter 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 186mph.2

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.

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 colored 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.

"The development of the XKR-S GT demanded an uncompromised approach to enhance aerodynamic down force, with complementary suspension changes to maximize high-speed cornering ability. In combination with the use of a carbon ceramic braking system, the result is the most focused 'R' model Jaguar has ever built."

– Pete Simkin, Director, ETO Specialist Products, Jaguar

Aerodynamics and chassis

"The XKR-S GT has been designed purely by the laws of physics. It has been developed in the wind tunnel and on the racetrack with the sole aim of creating as much high-speed stability and down force as possible. Nothing has been styled for the sake of it. It's been an exercise in efficiency and the result is a car that's raw, focused and devastatingly quick."
Ian Callum, Director of Design, Jaguar

The XKR-S GT features a wrap-around carbon-fiber front air 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. 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 186mph2 the XKR-S GT produces 320lbs (145kg) of down force. A new hood with shaped 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 setup 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 standard 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 two inches (52mm) 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.

"The XKR-S GT is an uncompromised car, but one that inspires confidence and encourages the driver to push it to its limits, fully exploring its handling abilities. It's a car that draws you in and is never intimidating, with performance that is both accessible and rewarding."

– David Pook, Technical Specialist, Steering and Handling, Jaguar

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 15.7-inches (398mm) and 15.0-inches (380mm) 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 46.3lbs (21kg). 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.

"The disc and pad materials are specially tailored for Jaguar characteristics. Because the XKR-S GT is a road car as well as one suitable for customers to take on the track, we engineered it for race-car braking performance but with no compromise to cold or wet weather ability."

– Edward Nixon, Group Leader, Brakes, Jaguar XKR-S GT

Performance

An all-aluminum 5-liter 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 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.

      So it's a GT car with a bunch of racing parts added on. Is this for people who want a track ready car like the GT3 , but don't want to be the fifth guy on the block with a GT3? The XK-R makes sense if you want a GT bruiser with a ton of power (like the SL and M6), but this car doesn't make a lot of sense to me. You're paying a large amount of money for car that won't be as comfortable as it's less expensive versions (track suspension), and won't be as fast as its track dedicated competition. Will it be a drift happy lunatic like the SLS and XK-R S? That's probably a lot of fun, but probably not very fast. Who takes a Jag to a track? I'd love to be enlightened.

      That's the same 5.0 block that sits in the Mustang GT (sans supercharger)... yet Jaguar's "version" runs you 5X the GT's price. I don't get it????

        The Jaguar engine is not the same as the Ford engine. They are not the same engine. Please know what you are talking about before you post something that is ignorant.

        Different blocks, different engines. Unlike you, I've actually seen both engines in person on engine dyno test stands. Besides, the vague scrap of text that you snagged from the interwebs, as you put it, does not provide any evidence otherwise. Do some actual research.

        No. The 5.0L engine used in Jaguars and the 5.0L engine used in Fords are totally different, they only share displacement size. Jaguar's 5.0L is an evolution of their 4.2L engine that was used for over a decade; the only US cars that used the 3.9L variant of this engine were the Lincoln LS and the Ford Thunderbird. Ford's 5.0L, used in the Mustang and the F-150, was developed to replace the old "Modular" 4.6L V8s.

          For the uniformed... I simply pulled this from the interwebs: The AJ-V8 engine is manufactured in an all-new, dedicated Jaguar facility located within the Ford Bridgend Engine Plant in Bridgend, South Wales. The Jaguar "plant-within-a-plant" saved considerable investment costs by Jaguar. It is staffed by workers dedicated to Jaguar engine production and includes a linked flow-line of computer numerically controlled machines with automated loading and assembly. Again, a FORD.

          Even the Land Rover new Evoke uses Ford's 2.0 Ecoboost (turbo) engine... I'm not saying Jaguar's use of a Ford block is bad, quite the opposite. It's just the price they're charging for it that's ridiculous.

          @ Demi.Hoor & adam1keith1980: If you bothered to cross-reference Wikipedia for more information on Ford's 5.0L Coyote, like you obviously did for Jaguar's AJ-V8 Gen 3 (to get that quote), then you should have noticed that the Ford engine uses a bore of 92.2 mm and a stroke of 92.7 mm, while the Jaguar engine uses a bore of 92.5 mm and a stroke of 93.0 mm. Don't confuse the fact that Ford is still a component supplier to Jaguar with the idea that they still exist under the same corporate umbrella. Ford just used ideas taken from the AJ-V8 to improve their "Modular" V8 to create the Coyote V8.

          Demi.Hoor, What part of dedictated Jaguar engine facility do you not understand? There are no Ford engines built at that facility. It's all Jaguar Land Rover and Volvo designed engines. This was Jaguar's engine plant before they were sold to Tata. It's seperated from the rest of the Ford plant which only builds 4 cylinder engines. Those of us who have actually seen both engines, know that the blocks aren't even the same shape. The Jaguar engine plant started production back around 1996. It's a full engine plant. There are over 50 Jaguar employees that oversee engine production there.

        I don't think I need to correct you. It appears you have been schooled! They are not the same block or engine. It is also 5X the car! Try driving one firsthand and experience the difference between the two yourself.

          Same block, You can bore any block to make it "unique", like they did for the S-type and LS. Guys, wake the F up!!!!!

          Demi is 100% correct. How much more proof do you need than what's in black in white: They're produced in the SAME Ford factory... the only difference is Jaguar now rents space in that same factory that used to be part of the bigger Ford Corp because the are now owned by Tata.

        JLR's AJ V8 is produced in Bridgend. Yes that is originally a Ford plant. However... U.S. Ford's Coyote V8 is produced in their Romeo, Michigan (US) and Windsor, Canada engine plants. Think about that. Why would they dedicate space and time at the Bridgend plant to make even more of the same Coyote V8's than they already make at TWO plants in North America? They have more than enough capacity at Romeo and Windsor to handle any production for a smaller volume car if they had to. Like they did for the 5.4L V8 and 6.8L Triton V10. Yes, I have been to both plants repeatedly. I worked for a major supplier to Ford. The reason is because it is a different engine with too many different parts to incorporate into the Romeo and Windsor plant. It needs it's own lower volume facility to meet JLR's needs. Go on Mitchell and look at the engine diagrams. Different. Now go have a drink or something. You sound so tired.

        Yep and the IS-F 5.0 liter engine is based on the Ford Coyote to as well. /sarcasm. Also there are plenty of supercars that use LS engines that are priced 3-4 times more then a corvette or camaro. Whats your point?
        FreeThinker
        • 2 Years Ago
        @Demi.Hoor
        Yes, those engine plants are originally owned by Ford of Europe. But R&D for the AJ V8 did not follow suit with the U.S. Ford Coyote V8. "Bridgend employs around 2000 people, and this year it is expected to build 600,000 engines for use in Ford vehicles, as well as 125,000 six- and eight-cylinder engines for Volvo, Jaguar and Land Rover. These engines include the 5.0-litre V8 designed for the all-new Jaguar XJ." The AJV8 was developed SPECIFICALLY for JLR with direct injection and supercharging in mind. Don't worry, I wouldn't expect you to understand why that is so significant from an OEM standpoint. The AJV8 and Coyote V8 have: Different bore size, different stroke length, different bore spacing, different heads, and different outside casting features. Feel free to scream at the ocean all you want, but the fact remains that these are different engines that each went through their own unique R&D cycle.

        I wouldn't say that. The ZLI did the Ring in 7:41 (very impressive). Jag claims that the GT will do it in under 7:40 which means that they have already bettered that time. So your comment is without merit. The fact that the ZLI cost so much less but can run a close time to the $174k GT is what's impressive.
