The Apple App Store has launched the acclaimed documentary Truth in 24 driving challenge application.

The application challenges iPhone and iPod touch players to monitor fuel use and tire wear just as Audi Le Mans teams do during races.

The Truth in 24 app is the second driving challenge Audi has introduced for the Apple devices. The Audi A4 Driving Challenge application, released last September, has enjoyed phenomenal success with nearly 3.2 million downloads to date.

The CEO of Factory Design Labs says:  ‘There’s a spirit of innovation in the Audi product lineup and marketing culture, and these games were designed to serve as the next logical step for both. We wanted to create an experience that would be similar to the challenges facing the actual Audi Le Mans drivers and the Audi racing team.’

The newest app relates to the award-winning documentary Truth in 24 produced by NFL Films and Chicago-based Intersport.

The film followed the dramatic 2008 bid by Audi racing teams to retain their dominance at the grueling 24 Hours of Le Mans endurance race, which has been one of the world’s premiere motorsports events for decades.
