Although "quattro GmbH" as a company may be relatively unknown, compared to its parent, Audi, its core products include the Audi RS4, the Audi RS6 and the Audi R8. Furthermore, it is a 'closed company', in that it does not sell its automobiles directly to the public via franchised outlets under its own brand name; instead, they are sold under the Audi marque. However, it does now sell 'quattro GmbH' branded lifestyle products and accessories via Audi franchised outlets and Audi Forum such as that located in the Allianz Arena on the northern outskirts of Munich, Germany.
