The Jaguar XF (codename: X250) is an executive/mid-size luxury car and estate produced by British car manufacturer Jaguar Cars which was first revealed in autumn 2007 as a replacement for the Jaguar S-Type.
The 2014 Jaguar XFR-S borrowed the exterior design elements from the XKR-S to distinguish it from the standard XFR. Carbon fiber played an important role in developing the aerodynamic package and it is used on the deeper front bumper with its larger lower-central and side air intakes, and the front splitter at the lower edge of the bumper. On the backside, the same material has been used for the central diffuser and the large rear wing.
The exterior package also includes extended side sills and aero blade, side moldings, an extended rear bumper, and a new spoiler that reduces rear lift.
Customers can choose between five exterior colors: French Racing Blue, Ultimate Black, Stratus Gray, Polaris White and Italian Racing Red. All of them will be combined with a gloss-black trim around the grille, around the front and rear screens, windows and across the trunk. The XFR-S will be offered with lightweight Varuna forged alloy wheels featuring a ceramic polish applied to the outer surfaces.
The interior also offers the same choices as the XKR-S. It includes a selection of carbon leather on the seat bolsters and armrests, and a dark mesh aluminum fascia. An exclusive feature for the R-S model is the Warm Charcoal leather trim on the seats, doors, seat bolsters and armrests. An R-S logo has been embossed on the seats and it can be finished with a choice of contrast color micro-piping and stitching in red, blue or ivory.
Under the hood, Jaguar has installed the same engine you will find in the XKR-S: a 5.0-liter supercharged V-8 unit that delivers a total of 550 horsepower and 502 pound-feet of torque. That’s good for an increase of 40 horsepower and 41 pound-feet of torque over the XFR. With the extra power the XFR-S will sprint from 0 to 100 km/h in just 4.4 seconds and up to a top speed of 300 km/h (electronically limited).
In order to obtain the extra power, the engineers needed to make revisions to the engine management system along with improvements to the intake and exhaust flow. The exhaust system replaces the central muffler with an X-pipe and near-straight-through rear pipes. Other changes include uprated half-shafts, a larger central bearing on the driveshaft, and a new torque converter.
The engine is mated to an eight-speed automatic transmission with Quickshift technology. It can be operated in manual, Sport or Automatic modes. While running in the first two modes it automatically blips the throttle to ensure the XFR-S accelerates smoothly out of corners. In automatic mode, it can detect the manner in which the car is being driven by monitoring acceleration and braking, cornering forces, throttle and brake pedal activity, road load and kick-down request. From there, the transmission makes adjustments on the fly.
The XFR-S is a car specially designed for high-performance driving, so to no one’s surprise, the suspension and braking systems also needed updated.
The suspension system has been updated and then tested on the Nurburgring track and in Nardo, Italy. The stiffness has been increased by 30 percent, the front knuckles have been revised and engineers added a new rear subframe.
The XFR-S is offered with standard 20-inch Varuna alloy wheels wrapped in Pirelli tires exclusively developed for the XFR-S, and measuring 265/35R20 and 295/30R20 front/rear. The wheels are combined with a high-Performance braking system that includes 380 mm (14.96-inch) front and 376 mm (14.80-inch) rear discs.
