At just 24 years old, Germany's Sebastian Vettel has secured his second consecutive Formula 1 World Championship after grabbing just the one point he needed at Sunday's Japanese Grand Prix. To commemorate the achievement, Polyphony Digital is offering a special Gran Turismo 5 online event, available for just one week. Just log on to the PlayStation Network and you'll have the chance to enter a time trial on the Japanese Grand Prix's Suzuka Circuit using the Gran Turismo 5 ultimate fantasy car, the Red Bull X2010. Up for grabs are 5 million credits. Everyone wins, though, as all participants will receive the X2010 in their garage, a prototype vehicle that was formerly earned only by completing every challenge in the game. Go here for instructions and details.
