D these ten points hurt. Ten points that were already on the account but were redeemed three hours after the Australian GP. FIA inspector Jo Bauer took precise measurements. The radius of the radius of the rear wing flap fell below the required minimum by two millimeters. A sloppiness of the manufacturing department. All other rear wings brought to Melbourne complied with the regulations.

Sauber is gentle on the tires

The Sauber C30 already showed a characteristic in the first race that it did in the first Half of the season brought many World Cup points. The white car was nice to the tires. This was due to the chassis, which still relied on the tried and tested Pushrod principle on the rear axle, and a well-thought-out aerodynamic balance. Even with starting positions between eleven and 16, the Sauber drivers were always good for championship points.

The tactic of making one stop less than the competition always worked with the exception of Valencia. The Sauber command post got its drivers safely through traffic using alternative strategies. Often it was only in the last third of the race that you noticed that Kamui Kobayashi and Sergio Perez were on course for points. Before that, they bobbed around inconspicuously in midfield. Only the astonishingly fast lap times on worn tires indicated that Sauber would have the stamina.

Perez with a strong rookie season

At the beginning Kamui Kobayashi played big on. The highlight was the Canadian GP when the Japanese was in second place behind Sebastian Vettel before the big rain break. In the end, it was only seventh. The longer the season lasted, the more Sergio Perez got going. The second in the GP2 series in 2010 strokes his tires while driving. The Mexican is the driver with the least wear and tear in the field. And he's still surprisingly fast.

Perez brakes early and steers gently into the corners. 'He has a good feeling for when the tires overheat and adapts his driving style. If it goes back, he quickly brings them back into balance with the front ones. Others run over the car and only increase the imbalance,' says team manager Beat Zehnder an attempt to explain. Pirelli tires remember every mistreatment. Braking or accelerating too aggressively once and the tire never recovers.

Peter Sauber sees an undiscovered talent in the Mexican: 'Sergio is on the way to becoming a great racing driver.He drives inconspicuously fast. 'The problem with Perez is the father. He persuades the son that he already has world championship qualities. That turns the GP newcomer's head. He's already dreaming of a Ferrari contract. That's why Peter Sauber made it It was strong that the father stayed at home as often as possible. Nevertheless: As a newcomer, Perez was an asset and did not sell any worse than the highly praised Paul di Resta.

Clean stops development of the blown diffuser

At the Spanish GP, Sauber brought its first major facelift. Part of the package was the blown diffuser. Although they had already practiced twice in Friday training sessions, Sauber also broke off the third attempt. The downforce fluctuated That unsettled the pilots. The track did not bring the progress that the wind tunnel promised. This was also due to the fact that Ferrari could not provide the appropriate engine control for its customers Glad that the FIA ​​wanted to ban active blowing on the diffuser from the GP England onwards.

Hinwil was already ordering supplies for the inward-pointing exhaust when the association suddenly made a U-turn. The big teams prevailed so that the technology survived until the end of the season. If Sauber had resumed work on the blown diffuser after the FIA ​​had changed its mind, a further 500,000 euros would have been burned.

In addition, the engine supplier Ferrari was still lagging far behind in the development of the engine maps at this point. It would have made little sense to invest in a diffuser development if nothing comes from the exhaust. That's why James Key, Head of Technology, decided: Let's concentrate on components that we can benefit from in 2012 as well. For example the new front and rear wings, which debuted in Suzuka and were rewarded with eighth place by Perez.

Sauber weakens itself

Maybe Sauber would have therefore should simply stick to his veto when voting in Silverstone. For the sake of peace, the other teams nodded their wish to keep the technology. But has any of the competitors ever looked at the fate of the Swiss racing team? It was only when there was renewed discussion at the end of the season, and Red Bull and McLaren in particular wanted to save part of the exhaust trick into 2012, did Sauber stick to his no. This time, however, Ferrari also stood by his side.

In the season finale, the lack of a blown diffuser became increasingly noticeable. The more the competition refined their systems, the more Sauber fell behind. 'There are two seconds between nothing like Sauber and the perfect solution from Red Bull,' believes Lotus technical director Mike Gascoyne. Peter Sauber claims: 'If the blown diffuser were banned, we would have one of the best cars in the field.' For that canBut he won't buy anything.

Sauber saves seventh place

The distribution of points clearly shows how much the lack of the aerodynamic trick Sauber had on the season. Up to the GP Germany, the Swiss troops had collected 35 points. In the last nine Grand Prix, only nine points were added. The temperature curves of Force India and Toro Rosso are completely different. The points before and after the GP Germany were distributed as follows. Force India 20/49, Toro Rosso 17/24.

With three places in the points in the last three races, Sauber still saved seventh place from Toro Rosso. That is four million more from Bernie Ecclestone's box office than it would have been in eighth place. Peter Sauber sees the overall result with one weeping and one laughing eye: 'Seventh place means an increase of one place compared to 2010. That is good, but we were secretly sixth on the agenda.'
