Boasting a bespoke bodykit with revised front and rear bumpers, twin bonnet vents, special XJR 575 badging and 20-inch gloss-black Farallon alloy wheels, the 575, like the rest of the XJ range, gets a 10-inch customisable touchscreen infotainment system, 12.3-inch Interactive Driver Display instrument cluster, improved 4G connectivity, optional 26-speaker 1 300-watt Meridian sound system, dual 10.2-inch rear entertainment screens and a new clutch of safety items such as Autonomous Emergency Braking with Pedestrian Detection, Lane Departure Warning with Lane Keep Assist, Driver Condition Monitor, Adaptive Cruise Control, Traffic Sign Recognition, Reverse Traffic Detection and Surround View Camera system.
Unique to the 575 are diamond quilted leather seats with 575 embroidered headrests, 575 branding on the dashboard, XJR 575 exterior badging and red brake calipers.
As its name suggests, the biggest change come up front where the familiar 5.0-litre supercharged V8 receives a 18 kW bump in power from 405 kW to 423 kW, enough to blast it from 0-100 km/h in 4.4 seconds, and on to a top speed of 300 km/h. Again producing 700 Nm, the V8 is linked to a ZF sourced eight-speed automatic gearbox.
Lesser models will again be offered in four trim levels; Luxury, Premium Luxury, Portfolio, R-Sport and Autobiography with a choice of standard or long-wheelbase body configurations, and with power either coming from a 250 kW 3.0-litre supercharged V6 petrol, a 221 kW 3.0-litre V6 turbodiesel or a 375 kW version of the 5.0-litre supercharged V8.
Pricing in the United Kingdom starts at £59 995 (R1 014 904) for the base diesel with the XJR 575 commanding a sticker price of £93 710 (R1 585 244).
