The XKR-S GT also gets a carbon ceramic brake system, for the first time in a production Jaguar. 398mm discs up front and and 380mm discs at the rear work with six- and four-piston monoblock calipers respectively to bring this lithe monster to a halt.
A wider front track, increased camber, revised bushings, a new steering system and faster steering ratio all improve handling. Height-adjustable and bespoke adaptive dampers feature a race-derived twin spring system.
The powerplant is the 550PS, 680Nm supercharged 5.0-litre V8 engine and power is transmitted to the wheels through a six-speed transmission and active electronic differential.
New, wider, 20-inch forged and lightweight alloy wheels are designed to optimise brake cooling and are shod with Pirelli Corsa 255/35 front and 305/30 rear tyres to maximise grip.
What sets the XKR-S GT apart from the XKR-S ?
Carbon ceramic brake systems as mentioned above.
Electronic Pre-Fill system pressurises braking system and maximises braking performance.
The aerodynamic aids mentioned ealier help the XKR-S GT achieve a maximum downforce figure of 145kg (320lb) at the XKR-S GT’s electronically limited top speed of 300 kph.
The addition of race-derived, height-adjustable and retuned adaptive dampers with twin-spring system. Spring rates have increased by 68% at the front and 25% at the rear.
New development of front and rear suspension with experience drawn from the development of the F-TYPE sports car
The fitment of an F-TYPE steering rack for enhanced agility
New, wider 20-inch forged alloy wheels shod with Pirelli Corsa 255/35 front and 305/30 rear tyres for maximised grip
As in other Jaguar supercharged cars, the bonnet louvres aid engine cooling and reduce under-bonnet air pressure
