There is a new King in town....

[Sir Nuke]

Mr. Raphanel who, in July, strapped himself into the new Veyron 16.4 Super Sport and circuited Volkswagen's Ehra-Lessien test track at an astonishing 268 mph, setting a new Guinness land-speed record for a production car.

the new Veyron 16.4 Super Sport

The list of modifications to the Veyron is long and expensive. The car now has four fuel pumps, compared with the Veyron's two, feeding the larger quad turbochargers. A less restrictive (and louder) exhaust system was developed. That and some engine-management programming increases torque to a hilarious 1,500 Newton-meters (1,103 pound-feet), and peak torque is higher in the rev band. Suspension-wise, the ride height was raised slightly (to accommodate greater high-speed downforce); and the air suspension, half-shafts, links and wheels were lightened, reinforced and laced tighter. The biggest changes were aerodynamic. The Veyron's lovely, roof-mounted air scoops are replaced with so-called NACA ducts. The main grille is larger, and the entire front of the car is more ventilated to provide cooling for brakes and the front Haldex differential. A wild double diffuser has been arranged in the rear. It's not a sports car, exactly, because despite the heroic use of carbon fiber everywhere, it weighs 4,043 pounds (110 pounds less than the Veyron). Also, it's all-wheel-drive, which means it's just about impossible to get it to rotate on the throttle, even with stability control turned off. Thanks to its enormous hydraulic rear wing, it summons up to 880 pounds of downforce, pressing the car down on its gigantic Michelin tires (14 inches wide on the rear). All of that makes the car majestically stable and locked down, with phenomenal amounts of cornering grip (1.4 g's). But it also means the car is about as flickable and tossable as an aircraft carrier.
The company plans to build 30 to 40 Super Sports and sell them for $2.5 million to $3 million.
