Preview: 2011 Jaguar XKR-S Convertible

Article by Christian Andrei, on June 17, 2011

A graphic rendering of how the upcoming Jaguar XKR-S is likely to look was made by Carscoop user L il-k Amaru. It can be recalled the Jaguar XKR-S wowed a lot of people at the recently held Geneva Motor Show with its bold styling and aggressive lines. It’s impractical to be used on the road but when positioned on the track, it’s formidable and is a serious competitor to its German rivals.

The production car is likely to have the same styling and awesome engine noise but unfortunately, it doesn’t have a roof to protect the occupants from the loudness of its 550hp engine.

The XKR-S Convertible will get a tweaked version of Jaguar's 5.0-liter supercharged V8 that delivers 550hp and 680Nm (501 lb-ft) of peak torque. In comparison, the standard car has an output that’s lower by 40HP and 70Nm. The car has a top speed of 186mph (300km/h), which is similar to the coupe.

It has a 0-60mph (98 km/h) acceleration time of 4.2 seconds. The revisions include a front bumper that has a stronger look, re-profiled side skirts, more air vents on the hood and bumpers, a big rear wing and a redesigned rear bumper that accommodates a diffuser and four exhaust tips.

The XK may have been designed to be a convertible but it won’t require heavy braces to handle the extra grunt of the engine when it switches to the rag top ‘R’. Jaguar is expected to sell the XKR-S Convertible for more than £100,000, considering that the Coupe is priced at £97,000 in Britain.

By adding in track work, wind tunnel work, and even the extensive Computational Fluid Dynamics to the Jaguar XKR-S Convertible, it became possible to make changes to its aerodynamic design. The main function of this is to ensure that the car is stable, even with the top down, at speeds going as high as 300 km/h (186 mph). Ian Callum, Jaguar Cars Director of Design, shared that it was truly exciting to apply the Jaguar XKR-S Coupe’s track focus philosophy to a convertible.

He added that driving a vehicle that can reach speeds this high, combined with the excitement of driving one with the roof down, can indeed make an emotion, as well as a special, experience. The changes made to the aerodynamic design make the car’s front have a daring and impressive look. In the new design, the bumper is where the vertical feature lines enter after going through the oval air intake’s edges.

This same bumper has integrated to it the twin side nacelles, splitter made of carbon fiber, and an air intake that is both lower and wider. At the bumper’s edges are the vertical panels that are able to direct air to the side through the new sills. The panels not only make the horizontal airflow smoother but they also highlight the fact that the ride height is lower by 10 mm. Meanwhile, the rear wing is unique and its carbon fiber inlay works well with the apron in the rear which has a carbon fiber diffuser.

As such, the overall lift is lowered by 26% which ensures that the aerodynamics of the front part and the rear portion is balanced. Helping highlight the changes done on the exterior is the gloss black applied to the brightwork. Complementing this change is the dark technical finish that is seen on the forged alloy lightweight 20-inch wheels with the Vulcan design. Through these wheels, it makes it possible to see the Jaguar High Performance Brake calipers that have the red finish or the discreet gunmetal finish.

The hood, which has been acoustically treated, can be closed or opened within 18 seconds. It may even be operated when the car is running at peak speed. Standard color for the hood is black with six additional colors made available. For the exterior itself, six colors will be offered with the two being the British Racing Green and the other the Polaris White, both of which honor the brand’s racing history.
