To a thumping soundtrack and an atmospheric setting, Red Bull took the wraps off the RB9 car it hopes will provide the English lineup with its fourth straight driver and constructor titles.

Reigning triple world champion Sebastian Vettel and teammate Mark Webber unveiled Sunday a car that is swathed in purple to promote a new title sponsor but appears to have few notable technological changes.

"It's very much an evolutionary car with the devil very much in the detail as we've tidied up a few bits from last year," said chief technical officer Adrian Newey, who designed the latest Red Bull challenger.
