The new $2.4 million Bugatti Veyron 16.4 Super Sport (www.bugatti.com) is an even more potent version of the original Molsheim monster, the Veyron 16.4, which Bugatti released five years ago. Introduced in August at the Pebble Beach Concours d’Elegance, the Super Sport has a 1,200 hp engine—notably more muscle than the standard Veyron’s 1,001 hp quad-turbocharged 16-cylinder—and a twin-clutch, 7-speed gearbox that is surprisingly tame. More feral are the Super Sport’s lateral acceleration of 1.4 gs and production-car-world-record top speed of 268 mph. A redesigned chassis and suspension improve the car’s handling, and reshaped air intakes and diffusers distinguish the Super Sport from garden-variety Veyrons. The new look will be short-lived: Bugatti plans to build only 30 Super Sports, and those will be the final Veyron models of any kind that the automaker produces.
