The Bugatti Veyron has been declared the world's fastest car at 268 m per hour.
The 0-62 mph sprint still takes about 2.5 seconds but 0-124 mph comes up in just 7.3 seconds and 186 mph passes in just 15 seconds.
Bugatti and its test driver Pierre-Henri Raphanel have already taken care of this, posting top speeds of 265.9 mph and 269.8 mph in a Guinness world record attempt.
The final number for the record books was 268 mph, a figure that took Bugatti''s engineering team by surprise.
According to The Sun, the Bugatti Veyron SuperSport features an output of 1,200 horsepower and 1,106 pound-feet of torque, brought about by four enlarged turbochargers and bigger intercoolers to increase boost feeding its 8.0-liter W-16 engine.
At the same time, the chassis has been extensively redesigned to maintain safety at extreme speed--thanks to slightly raised main-spring travel, stronger stabilizers, and new shock absorbers with a complex architecture originally developed for racing cars.
The end result is noticeably more precise control of the wheels and the car as a whole.
The body has also been fine-tuned to improve aerodynamic efficiency, while the new fiber structure of the all-carbon monocoque ensures maximum torsion rigidity and passive safety--at reduced weight. The skin is made entirely of carbon-fiber composites, which customers can enjoy if they opt for the 100 percent clear- lacquered finish.
It is easy to spot the new Veyron Super Sport from the regular model thanks to its flat and elongated silhouette. The car's W-16 engine gets its air from two NACA ducts integrated into the roof, rather than from scoops above the engine.
The front air intakes have also been expanded and reshaped, with the lower one extending elegantly around the sides to the wheel arch. The revised back looks sportier due to the double diffuser and a centrally arranged exhaust system.
The Bugatti Veyron Super Sport will begin production this autumn at Molsheim, France along with the Veyron and the Grand Sport.
The first five cars--known as the World Record Edition--are in a special black exposed carbon and range finish and have already been sold at 1.8 million dollars each.
