Wind-in-hair is one of the joys of open-air motoring, but this baby could blow your wig into the weeds. One of the Veyron's Grand Sport collection, the 16-cylinder engine has been tweaked to generate 1200 horsepower and 1106 pound-feet of torque, yielding a top speed capability of 254 mph, according to Bugatti. It's possible that this may sound excessive to some, but it does allow Bugatti boss Dr. Wolfgang Durheimer to call it "the fastest roadster ever," which is hard to dispute. Interested? Hurry. Production will probably amount to around 50 units.
