Bugatti is claiming a new production car top speed record with a combined two run average of 431.072km/h (267.91mph) with a new Veyron 16.4 Super Sport model – in the process smashing the 408.30km/h (253.76mph) set by a standard Veyron 16.4 in 2005 by 24km/h (14.9mph).
It also betters the existing world record mark of 412.28km/h (256.23mph) established by low volume US car maker, Shelby SuperCars, with its Ultimate Aero on a closed 19km (12 mile) stretch of road in Nevada in 2007.
Confirming details of the attempt run under tight security at parent company Volkswagen’s 21km (13 mile) Ehra-Lessien test track in late June, Bugatti says the new Supersport set the record at the hands of its test driver, Pierre-Henri Raphanel and under the auspices of officials from the Guinness Book of Records.
In the first round of the attempt running in anti-clockwise direction against a prevailing wind the Super Sport hit 427.933km/h (265.96mph). It then went on to reach a wind assisted 434.211km/h (269.86mph) in a clockwise direction, giving the powered up Veyron 16.4 a combined average of 431.072km/h (267.91mph).
The new Super Sport, which Bugatti plans to produce in a limited run of no more than 30 units, is set to be the last hurrah for the Veyron 16.4, taking overall production of the flamboyant quad-turbocharged 8.0-litre 16-cylinder powered supercar up to 300 since its introduction in 2005.
Boasting lightweight carbon fibre body created using a new fibre construction and clear finish, the four-wheel drive Super Sport is claimed to weigh 50kg less than the standard Veyron 16.4 at 1840kg. Bugatti has also tweaked the Veyron 16.4’s engine, taking its peak power from 987bhp to 1183bhp. Torque also increases from 921lb ft to 1106lb ft.
