Bugatti Veyron 16.4 Super Sport hits 268 mph

Bugatti is claiming a new production-car top-speed record with a combined two-run average of 267.9 mph (431.072 kph) with a new Veyron 16.4 Super Sport model, smashing the 253.76-mph record set by a standard Veyron 16.4 in 2005. It also betters the existing world-record mark of 256.23 mph (412.28 kph) established by Shelby SuperCars with its Ultimate Aero on a 12-mile stretch of road in Nevada in 2007. Confirming details of the attempt run under tight security at parent company Volkswagen's 13-mile Ehra-Lessien test track in late June, Bugatti says the new Super Sport set the record in the hands of its test driver, Pierre-Henri Raphanel, and under the auspices of officials from the Guinness Book of Records.
