Enticed by the XKR-S, but decide that the coupe was just a little too impractical? Say hello to the 2014 Jaguar XFR-S ($99,000). 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. Limited to just 100 units in the U.S., it'll go on sale next summer.
