The pinnacle of the Jaguar sporting range - the XKR-S - is now joined by a convertible which offers the same enticing blend of abilities, while offering driver and passenger a heightened connection with their surroundings.

The XKR-S Convertible embodies all the characteristics that have always defined legendary Jaguar GTs - explosive performance, involving handling, relaxed comfort and discreet luxury - while taking Jaguar into a new performance echelon. The new XKR-S model line-up sits at the pinnacle of the XK range, which now consists of XK, XKR and XKR-S derivatives in coupe and convertible format.

Adrian Hallmark, Jaguar Global Brand Director, says the new XKR-S Convertible represents the pinnacle of performance and glamour in motoring: “There is nothing as liberating as life behind the wheel of an open-topped Jaguar and the new XKR-S Convertible takes the Jaguar GT experience to new heights.”

The building block for the car’s explosive performance is an uprated version of the 5.0-litre supercharged AJ-V8 engine, which produces 550PS (405kW) and 502lb/ft (680Nm) of torque. These figures represent a power increase of 8 percent and torque increase of 9 percent over the Jaguar XKR. Driving the rear wheels through a six-speed automatic gearbox with Active Differential, this propels the XKR-S Convertible to 60mph in 4.2 seconds (0-100km/h in 4.4 seconds) and on to an electronically limited top speed of 186mph (300km/h).

Extensive Computational Fluid Dynamics, wind tunnel and track work has resulted in the aerodynamic design changes applied to the XKR-S Convertible. These perform an essential function in maintaining stability in an open-topped car capable of speeds as high as 186mph (300km/h).

“Taking the track-oriented ethos of the XKR-S Coupe and applying it to a convertible is very exciting. There is a real spirit and thrill to driving with the roof down and in a car capable of these speeds that is going to be exaggerated to create a very dramatic and special experience.”
Ian Callum, Director of Design, Jaguar Cars.

The engineering integrity of the acclaimed AJ-V8 petrol engine, now in its third generation, meant that Jaguar’s engineers could derive the extra power and torque needed for the XKR-S. The advanced design of the quad-cam, all-aluminium AJ-V8 incorporates spray-guided direct injection and variable valve timing for great efficiency as well as prodigious power. The Roots-type twin-vortex supercharger nestling in the ‘V’ of the engine has twin intercoolers and is 20 percent more thermodynamically efficient than its predecessor.

With the XK model designed as a convertible from the outset, Jaguar’s engineers were able to apply the changes that created the XKR-S Coupe into the open-topped GT without compromising performance, agility or refinement.

With the convertible hood stowed away, the interior of the XKR-S will be subject to as many envious glances as the exterior, with both highlighting the car’s high performance intent.
