Just a few weeks ago Infiniti launched a new roadside assistance app for users of the Apple iPhone, and before that we saw MINI launch its own version, while Mercedes-Benz has had its mbrace assistance feature for what seems like forever. Now Audi is joining the fray with its own free roadside assistance app for the Apple iPhone and iPad, as well as BlackBerry and Android smartphone users.

The new app, dubbed the Audi Roadside App, works by accessing an Audi vehicle's basic information, which is stored as part of the broader roadside assistance service. It delivers some emergency and concierge services directly to the smartphone--everything from locating dealers to connecting with the nearest service center for repairs.

Using the phone's GPS services and VIN information registered on first sign-in, the app can pinpoint who's trying to reach Audi's third-party service provider, and where they'll be needing a helping hand.

The feature then connects users to a team of customer service staff with a comprehensive nationwide towing network to bring assistance when needed. Audi includes complimentary 24/7 roadside assistance on all new models sold in the U.S. for the first four years of ownership. Owners of older models can still use the app, but roadside service fees would apply.

The Audi Roadside App is available now as a free download via the respective iTunes Store, BlackBerry App World and Android Market. Note that it’s only being offered for U.S. customers currently.
