Volkwagen has released a unique new racing game for the iPhone and iPod touch that challenges players to drive efficiently rather than simply fast. In Think Blue Challenge players are rewarded for efficient driving and maximum range, with the goal of racking up the most kilometers by consuming the least amount of fuel. Quiz questions are presented between each game stage to provide tips on how to play and fuel bonuses for correct answers. Scores can be submitted to an online high score table and players can also submit their scores to the Volkswagen eGames Facebook page. Volkswagen Think Blue Challenge is available from the App Store as a free download.
