Audi A4 Driving Challenge... Enhanced version 2.0... Audi of America, Inc. thanks you for your reviews and feedback. We've listened and we've responded. Please enjoy the enhanced 2.0 version and as always, we welcome your feedback.

The Audi A4 Driving Challenge is about precision performance driving. Use the iPhone's motion sensing accelerometers to test your skill against a series of challenging courses. Each course includes features intended to hone your reflexes, control and anticipation. The player will complete three laps across a series of five courses, receiving a time for each course. Don't clip the cones! Each cone the player hits will add a full second to their lap time.

Just like real driving, it's better to slow down and remain in control than to constantly speed ahead at full throttle. Use of the brake and mastery of the course will be required to get a good time.

If you're ready for a driving skill game that isn't just "pedal to the metal," this game is for you!
