The Sauber C20 was the car with which the Sauber Formula One team competed in the 2001 Formula One season. It was powered by a Petronas-branded '01A' 3.0-litre V10, supplied by Scuderia Ferrari. The C20 was notable not only for its eventual position in the Constructors' World Championship but also for a new type of front suspension mounting: the "twin keel".
