The game appears on the Top Gear website. Users must drive the Mercedes-Benz C-Class around a virtual version of the Top Gear test track and beat the Stig's time. The Stig is the mystery racing driver who appears on the BBC Two television show.
All players are entered into a draw to win a day at the 'Top Gear' track, and one of the winners will then be given the chance to drive a top-of-the-range Mercedes C32 AMG for a week.
The promotion is backed by advertising in the June edition of Top Gear magazine and online support including site banners, buttons and skyscraper placements.
The activity was planned and bought by BJK&E Media and the game was built internally by Top Gear.
Richard Friar, media planner and buyer for Mercedes-Benz, said: "The promotion will work for Mercedes-Benz on two levels. Firstly, it presents an opportunity for the 'Top Gear' audience to interact with the brand, as well as forward on to friends and even create a bit of office competition.
"Secondly, the promotion will be a key instigator in generating lead enquiries and test-drive results for the C-Class range. The very nature of the competition exemplifies the sporting yet affordable values of the C-Class range."
