There’s a new Audi A4 free application for the Apple iPhone via the Apple iTunes App Store. The original Audi A4 driving challenge for iPhone was downloaded 3.2 million times so was quite successful.

Now, according to Intomobile, Audi has released their second instalment for the Apple iPhone called, Truth in 24. Obviously Truth in 24 is a driving application and apparently “challenges iPhone and iPod touch players to monitor fuel use and tire wear just as Audi Le Mans teams do during races.”

Truth in 24 for the iPhone features multiple race courses and given the iPhoner the drive from the driver’s point of view and well as it is a free application there’s really no reason not to download it is there.
