The Sauber C31 is a Formula One racing car designed by Sauber for use in the 2012 Formula One season. The car is due to be driven by Kamui Kobayashi and Sergio Pérez. Technical director James Key announced that he was leaving the team just four days before the C31 was due to be launched at Jerez de la Frontera.
The C31 achieved its first podium, with Pérez behind the wheel, at the Malaysian Grand Prix.
At the Spanish Grand Prix the Chelsea FC logo was added to the car.
On June 10, Pérez achieved his second podium of the season at the Canadian Grand Prix with third place, while Kobayashi added a ninth place to help Sauber move up to sixth place in the Constructors' Championship.
For the German Grand Prix the C31 achieved its best points haul of the season with Kobayashi coming in fifth position before a penalty pushed him up into fourth, with Pérez following him home in sixth, giving the team 20 points in one round. This was their best scoring round since returning to Formula One as a privateer team.
After a long summer break, the Great Circus returns with the Belgian GP where Sauber are located in the top 10 qualifying, Kamui will start in second and Checo in fourth place (the best grid in Sauber's history). During the start of the race, Romain Grosjean caused a spectacular crash leaving out of action Sergio Pérez, the championship leader Fernando Alonso, Lewis Hamilton and the French driver as well. Kobayashi's Sauber was also damaged and instead ended just 13th place. Grosjean was fined 50,000 Euros and the suspension of the next race to be held in Monza.
