Sauber Motorsport

Sauber Motorsport AG was a Swiss motorsport engineering company and race team founded by Peter Sauber as PP Sauber AG in 1970, first building sports cars and later Formula One cars as an independent constructor. Its early cars were numbered with the letter C in honour of Sauber's wife Christiane, starting with the C1 built in his parents' garage, and its Sauber C9 won two consecutive world endurance championships, while the team took overall victory at the 1989 24 Hours of Le Mans with Mercedes-Benz. The team entered Formula One in 1993 and became known for bringing on young drivers such as Heinz-Harald Frentzen and Felipe Massa. BMW bought it in 2005 and ran it as BMW Sauber from 2006 to 2009, winning the 2008 Canadian Grand Prix, before Peter Sauber bought it back for one euro. It left Formula One in 2025 after its assets passed to Audi in 2024 to form the base of the Audi F1 Team.
