The Audi A1 clubsport quattro is a high-performance concept car that was unveiled at the 2011 Wörthersee Volkswagen and Audi Meeting. It is based on the Audi A1 and is powered by a modified 2.5 litre 5-cylinder engine from the Audi RS 3 and the Audi TT RS. Like most sports cars today, the clubsport quattro has a lightweight construction. The A1 clubsport quattro influenced the exterior design of the 2012 Audi A1 2.0 TFSI model.
