2014 Jaguar XFR-S

If there's something wrong about a sedan with a 550-horsepower supercharged V8, we don't want to hear about it. Instead, we want to marvel at the car in person, which is fortuitous because Jaguar has officially unveiled the 2014 XFR-S at the 2012 LA Auto Show. That blown 5.0-liter V8 dishes up a full 502 pound-feet of torque, which is good enough to shuttle the four-door to 60 mph in a scant 4.4 seconds. And, thanks to a start stop system and a few other fuel-saving tricks, the 2014 XFR-S gets away without being hit by the gas guzzler tax.

That's all good news, but we're just as excited about the fact that engineers managed to crank up the vehicle's chassis stiffness by a ludicrous 30 percent. Stiffer dampers and springs also give the car a little more poise, and a wide-open exhaust lets the whole world know you're kicking down their door. You know, in case the electric blue paint and wild body work didn't tip your hand. Check out the full gallery above for a closer look.
