Engineers have added a revised suspension set-up with new springs, dampers, anti-roll bar and a recalibrated Computer Active Technology Suspension (CATS) system to improve handling. The supercharged 4.2L all-aluminum V8 gets a recalibrated engine management system that enables the XKR-S to reach a top speed of 174mph, 19mph faster than the (electronically limited) regular XKR. Peak output remains at 420hp and 560Nm of torque, which is enough to see the new model sprint from 0-62mph in just 5.2 seconds.
Visual enhancements include a new front air-splitter and side sill-extensions, a revised rear spoiler and new bumper with an integrated diffuser. Rolling stock consists of 20in Vortex alloy wheels housing Alcon R Performance brakes with red monobloc six-piston callipers and 400mm brake discs.
Despite the performance connotations, the XKR-S still features plenty of luxury items such as full soft grain leather trim, piano black dashboard elements, and a revised instrument cluster calibrated to accommodate the car’s higher top speed. Developers have also added Jaguar's 525W Premium Audio system but customers can also opt for a Bowers & Wilkins tuned system with speakers made out of Kevlar and aluminum.
