Audi Sport GmbH, formerly known as quattro GmbH, is a high-performance division of Audi, a division of the Volkswagen Group.
Founded in October 1983 as quattro GmbH, it primarily specialises in producing high performance Audi cars and components, along with purchaser specified customisations. The company's former name was an homage to Audi's original four-wheel drive rally-inspired road car—the Audi Quattro. In 2016, the company was renamed Audi Sport GmbH.
