Most Expensive Car in the World

the Bugatti Veyron 16.4 Super Sport, has an estimated price tag of $2.3 million.
Its W16 engine—essentially two narrow-angle V8s sharing a crankshaft—with four turbochargers generates 1,200 hp and, along with improved aerodynamics over the original Veyron, allows it to reach a top speed of 268 miles per hour. That makes the Super Sport the fastest production car in the world.

The  Bugatti Veyron 16.4, hits 60 mph in 2.5 seconds, does the quarter-mile in 10.5 seconds and reaches its top speed of 252 mph in just 55 secs. It came after a long absence from the market for Bugatti and helped the brand reclaim its title as the ultimate performance car and reign supreme as the world’s most expensive production car.
