British manufacturer Jaguar will show up at the 2013 New York Auto Show (March 29-April 7) to introduce the exclusive XKR-S GT, a special limited edition that will see just 30 cars built for the North American markets (meaning 25 units for the United States and 5 for Canada).
The model is a sort of extreme evolution of the already staggering XKR-S and comes with a pretty elaborated aerodynamic package featuring a wrap-around a carbon-fiber front air splitter, an aluminum front undertray, carbon-fiber twin dive-planes and wheel arch extensions, carbon-fiber diffuser, rear wing and decklid-mounted spoiler. As a result, the XKR-S GT enjoys 145 kg of down force when reachin its electronically limited top speed of 300 km/h (186 mph).
The car is equipped with the same 5.0-liter supercharged V8 equipping the ‘regular’ XKR-S model - which, in combination with the 6-speed automatic transmission by ZF, allows it to sprint from 0 to 100 km/h (62 mph) in 3.9 secs - but the GT is filled with a number of different technical solutions. Braking comes from a carbon-ceramic system with 398 mm and 380 mm discs front/rear, gripped respectively by six- and four-piston monoblock calipers, aided byan electronic “Pre-Fill” system that pressurizes the brakes on throttle lift to maximize braking performance. It is actually the first time that such a brake system has been fitted to a production Jaguar vehicle.
Newly developed front and rear suspension use height-adjustable adaptive dampers featuring a race-derived twin spring system, with rates increased by 68% at the front and 25% at the rear. In the comparison with the car it derives from, the GT has a wider front track, increased camber, revised bushings, a new steering system and faster steering ratio. The Jaguar XKR-S GT rolls on new, wider 20-inch forged alloy wheels shod with Pirelli Corsa 255/35 front and 305/30 rear tires, and is equiepped with a fully active performance exhaust system with valves that open under load to enhance gas-flow and maximize power output.
