Audi has launched their new Audi on Demand service which allows customers to rent a car for up to 28 days at a time.

Audi has launched their new rental service in San Francisco.

Dubbed Audi on Demand, the service allows customers to reserve one of their models for up to 28 days at a time.  Audi declined to go into specifics but said customers can use an iOS app to select from a variety of models - including everything from the A4 to the R8 - and then have the car personally delivered to them at the location of their choosing by an Audi on Demand concierge who will help the customer get "acquainted with the vehicle, from setting music preferences to tailoring the navigation system."

Since Audi wants to put their best foot forward, all Audi on Demand models will be Premium Plus variants that features MMI Navigation plus, quattro all-wheel drive and SiriusXM satellite radio - among other things.

The service is currently in "beta" but Audi says it will eventually be rolled out to additional U.S. cities in the coming years.

According to Audi of America Executive Vice President and COO Mark Del Rosso, “Audi on Demand embodies the brand’s core values of technological progress and a love for discovery."  He went on to say "While competing services point their customers to vehicles parked on the street, Audi on Demand delivers a truly premium experience, with concierges personally delivering and returning vehicles for customers where and when they need them.”
