Say hello to the 2014 Jaguar XFR-S. The fastest, most powerful sedan Jaguar has ever produced, the XFR-S is powered by the same 5.0L supercharged V8 as its two-doored stablemate, giving it 550hp and a 0-60 mph time of just 4.4 seconds on its way to a top speed of 186 mph. Despite the speed, it still manages to eek out 23 mpg highway, and also features a ZF eight-speed transmission, wide 20-inch Varuna forged alloy wheels, and plenty of carbon fiber components to help reduce weight and lift.
