Jaguar recently unveiled the latest dramatic evolution of its supercharged 2011 XKR coupe at the Geneva Motor Show. This XKR delivers a significantly increased maximum speed – up to 175 mph from 155 mph – and bold styling changes that create an evocative and unique supercharged Jaguar.
The XKR Coupe unveiled at Geneva showcases two new optional performance and styling packs – Speed Pack and Black Pack – introduced to the XK range for 2011. Jaguar customers have the option to personalize their vehicle to create a car that offers even greater performance without compromising the refinement and luxury for which every Jaguar is renowned.
By raising the XKR’s maximum speed the new car has extended its sporting credentials taking it even further into supercar performance territory.
The XKR Coupe with new optional Speed Pack allows customers to further strengthen their XKR’s already impressive breadth of capability, by extending the car’s top speed from 155 mph to an electronically limited 175 mph thanks to a unique engine and transmission recalibration.
To ensure the XKR with Speed Pack remains stable at high speeds, the coupe uses a revised front aerodynamic splitter and larger rear spoiler to provide increased balance and a reduction in lift. The XKR’s computerized Active Differential Control also adjusts to reduce steering sensitivity at very high speeds, further improving stability and driver control.
Every XKR with the Speed Pack will come with body-colored side sills and rear diffuser, and a chrome finish to the window surrounds, upper and lower mesh grilles, side Power Vents and boot lid finisher. Red brake calipers with a Jaguar ‘R’ logo sit inside 20-inch Kasuga alloy wheels.
Available as a stand alone option or in addition to the Speed Pack, XKRs fitted with the Black Pack have a paint palette selected from colors that Jaguar’s Design team believe to be ideal for creating a coupe with immediate exclusivity. The Black Pack models will be available in Ultimate Black, Polaris White or Salsa Red and boast eye-catching 20-inch gloss black Kalimnos alloy wheels. Further gloss black finishing is applied to the window surrounds and front grilles. Red painted brake calipers contrast strongly with the black alloy wheels, while body colored front and rear spoilers and boot lid finisher round out the package. Customers also have the option to apply a sweeping ‘XKR’ side body graphic that runs along the door sills.
MERCEDES BENZ SLS AMG GT3
Mercedes-AMG is presenting a GT3 variant. This racing version of the gullwing model stands out with its spectacular design and thoroughbred motor sports technology. Developed to comply with the GT3 specifications of the FIA (Fédération Internationale de l’Automobile), the SLS AMG GT3 is designed as a racing sports car for customers competing in sprints and long-distance races.
The new SLS AMG GT3 is wide, flat and has spectacular racing car looks. The main focus when modifying the body of this gullwing model was on aerodynamic performance – as is seen not only in the new front apron with a splitter, the hood with its central cooling air vent and the wider front and rear wings, but also in the the side wheel arch air vents, the sideskirts with cooling ducts for the rear brakes, the smooth underbody with a rear diffuser and the adjustable rear aerofoil. All these features ensure a low drag coefficient and maximum downforce – while guaranteeing effective cooling of thermally highly stressed components. The C-pillars accommodate the standardized filler pipes for the fast-refuel system.
The maximum output of the AMG 6.2L V8 front-mid engine with dry sump lubrication on the “Balance of Performance” principle. This is intended to ensure that all the racing cars taking part have an equal chance. The classification process, during which the curb weight is also determined, will be completed in 2010. Power transmission in the GT3 variant is by a sequential six-speed racing transmission with steering wheel shift paddles and an integrated multi-disc locking differential. As in the standard SLS AMG, the transmission is located at the rear axle: the engine and transmission are connected by a torque tube within which a carbon-fiber shaft rotates at the engine speed, as in the roadgoing version.
