2014 Jaguar XFR-S Sedan

At the recent Los Angeles Auto Show, Jaguar showed its upcoming 2014 XFR-S Sedan. The Sedan joins the 2012 XKR-S as the second model in the ultra-high performance R-S range.

With 550 hp and 502 lb-ft of torque under the hood in the form of a blown 5.0L, the XFR-S certainly has the credentials to qualify as ultra-high performance. It is the fastest and most powerful sedan ever produced by Jaguar. Jaguar says the four-door will do the 0-100 km/h sprint in just 4.6 seconds. It has an electronically limited top speed of 300 km/h, enough for most tracks in North America.

Behind the motor is an eight-speed automatic with “Quickshift” technology that can be shifted fully in automatic mode or by paddle shifters. The transmission will blip the throttle on downshifts, hold a lower gear automatically through corners and during quick overtaking maneuvers, and perform multiple and very rapid downshifts during hard braking.

The XFR-S’s suspension has been seriously upgraded for track performance. Overall lateral suspension stiffness has been increased by 30 percent front and rear, with front and rear spring rates increased by the same amount. Front suspension knuckles have been revised in line with those found on the XKR-S to achieve the increased camber and castor stiffness.

At the rear, a new sub-frame enabled revisions to suspension geometry, stiffer bushings, new rear knuckles, and stiffer springs. The XFR-S uses new lightweight, forged 20-inch Varuna alloy wheels. These are a half-inch wider at the front and an inch wider at the rear compared to the wheels on the XFR. The tires, developed in conjunction with Pirelli exclusively for the XFR-S, are 265/35R20 and 295/30R20 front/rear.

Changes on the inside are limited to carbon leather on the seat bolsters and armrests and a dark mesh aluminum dash. Buyers may choose contrasting color stitching and micro piping, which can be matched to the exterior paint scheme.

Just 100 of the beasts will be available for the US (so for Canada, if available at all, do the math). But not to worry, my guess is they’ll be discounting this customized XF by this time 2014. Judging by the comments I heard at the LA Auto Show, it would be hard to imagine that in all of North America there are 100 individuals with the kind of cash that can buy almost any car that would want this sedan.

The XFR-S looks like it was designed from the Canadian Tire catalogue. The “aero” body kit, the big wing mounted on the trunk and the in your face French Racing Blue (there are four other less frightening colours) could have been applied on a weekend by a few well-intentioned, but not necessarily skilled, high school students.

Jaguar, of course, sees it differently: “Reflecting the changes under the skin, the XFR-S is distinguished from the XFR by subtle design changes that give it a distinctively assertive appearance while also enhancing aerodynamic performance.”

There is nothing subtle about the XFR-S. It is as distinctively assertive as a Rhinoceros in your swimming pool. And if we read further, the XFR-S probably needs a little aerodynamic enhancement if you want to live at 300 km/h.

Jaguar’s press materials say the aesthetics of the car were dictated by the aerodynamic solutions.
The “extended rear bumper also incorporates a central, carbon fiber diffuser, deeper than the item found on the XFR and which travels further under the rear of the car to help reduce lift.”

“Rear lift is also reduced through the fitment of a spoiler to manage the airflow coming off the top rear surface of the car. Two spoiler designs are available, both of which have been designed with the aid of computational fluid dynamics to provide optimally balanced aerodynamics. The larger of the two rear wings is constructed with a carbon fibre aero-foil center section. The combined result of the bodywork revisions is a reduction in overall lift of 68 percent.”

Or in other words (mine), thanks to a body kit we found in the basement of the LA Convention Centre (where aftermarket products are displayed) the XFR-S’s tendency to become airborne at speeds over 250 km/h has been reduced by 68 percent.
