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 (see below), but also for a new type of front suspension mounting: the "twin keel".
The twin keel
The effect of airflow underneath the nose had first become apparent in the early 1990s. By the end of the decade, most teams had settled for a design where both lower front suspension arms were mounted from a single longitudinal “keel” running underneath the nose. For 2001, the FIA introduced a regulation lifting the sides of the front wing by 50mm, in order to reduce downforce and cut cornering speeds.
Sauber had introduced separate pylons for each of the front suspension mounts on their previous car, the C19. For the C20, the area between the front and back mounting points on each side was filled in, creating two longitudinal keels running underneath the sides of the nose.
In contrast to the previous season's experienced pairing of Mika Salo and Pedro Diniz, Peter Sauber signed Germany's Nick Heidfeld and Finnish rookie Kimi Räikkönen. His lack of experience prompted some drivers and FIA officials, including Max Mosley, to question the wisdom of this decision. Heidfeld had made his debut with Prost Grand Prix in 2000, but Räikkönen was a 21-year old whose only previous single-seater formula experience amounted to one and a half seasons in British Formula Renault from 1999 to 2000, albeit culminating in a title win.
However, the young Finn's performances belied his age and lack of experience, with a point-scoring finish on his debut and a further four points-scoring finishes throughout the year. Heidfeld achieved a podium (one of six in Sauber's history) with third place in the Brazilian Grand Prix and scored points on six other occasions.
Constructors' World Championship
The C20 turned out to be arguably Sauber's most competitive chassis, providing Sauber with a points total of 21 and fourth place in the Constructors' World Championship standings. Sauber never equalled this result, though it came close in 2002, with fifth place.
The C20 achieved 11 points finishes and 10 non-scoring finishes from 33 starts.
