Bentley Continental Flying Spur Speed: the world's fastest sedan?

London Motor Show 2008 Some may want to pick nits about the definition of "fastest" but we do know that this Bentley is supremely quick and mind-numbingly luxurious.

The Speed version of the Bentley Continental Flying Spur has twin turbochargers attached to its W12 engine — for those curious, that's two V6 welded together in mechanical matrimony in a "W" shape. It pumps out 449 kilowatts of power — or 600 horsepower in old money — which propel it from 0 to 100km/h in 4.8 seconds and a top speed of 322km/h. This is also the first car also we've seen with the Naim audio system, a super high quality stereo with 15 speakers and an output of 1,100 watts.

If you don't feel the need, the need for speed, there's a "normal" Continental Flying Spur with just 412kW, giving it a 0 to 100km/h time of 5.2 seconds and a measly top speed of 312km/h. Pfft, slow coach.
