And the award for Top Speed Achieved by a Production Automobile goes to: Shelby Supercars' Ultimate Aero Twin Turbo. Claiming a stretch of public road in Washington State for the effort, the SSC UATT made two runs in accordance with Guinness Book of World Record rules, one in each direction. The first run clocked 257.11 MPH, the second, return one came in at 254.55 MPH. The average: 255.83 MPH. That bests all challengers -- yes, even the Veyron -- by at least 3 MPH.

For comparison, the SSC's V8 packs 1,183 BHP and 1,094 ft-lbs. as opposed to the Veyron's 16 cylinders, 1,001 HP, and 922 ft-lb. In addition to a bigger punch, the SSC also carries less weight: 2,700 pounds versus the Veyron's 4,162. Much of the Veyron poundage no doubt is attributable to its interior, which is a splendid place to be even when you're not doing 250+. SSC still needs to submit the paperwork and get official certification from Guinness before it's run is, as we say, officially official. Intriguing, though, that of all the names mentioned, the one not broached was the previous holder of the top speed record: the Callaway Sledgehammer.
