Brazilian driver Rubens Barrichello and Nico Hulkenberg of Germany will drive for Formula One team Williams next season. Barrichello, who will be leaving constructors' champion Brawn GP, is 37 years old and has won 11 races in a record 284 F1 starts. The 22-year-old Hulkenberg won the GP2 Series championship this year and served as a test and reserve driver for Williams. “Rubens needs no introduction. He is not only the most experienced driver in Formula One, but a passionate and talented driver who fought hard for the drivers' championship this year,” Williams team principal Frank Williams said. “Nico Hulkenberg won the GP2 title this season as a rookie and has previously won the F3 Euroseries, Formula Masters, A1 GP and Formula BMW Germany.” Barrichello, who was third in the drivers' championship, and Hulkenberg are replacing Nico Rosberg and Kazuki Nakajima at Williams. Rosberg is rumored to be headed to one of the Mercedes-powered teams next year, either McLaren or Brawn. Williams finished seventh in the constructors' championship this year, but the team has not won a race since Juan Pablo Montoya finished first at the 2004 Brazilian Grand Prix.
