Zhou returns to Sauber F1’s previous car setup for the Spanish Grand Prix.

Zhou Guanyu, Chinese driver competing in the Formula 1 World Championship, will use an older version of the Sauber C44 car for the upcoming Spanish Grand Prix. This decision comes after Zhou has faced numerous challenges and difficulties since the changes made to his car in Imola. Throughout the first nine races of the season, Zhou has been unable to score any points and was eliminated in the first qualifying session. The most recent race at the Circuit Gilles Villeneuve was particularly tough for Zhou as he had several crashes during practice and qualified as the slowest driver. One of the main problems Zhou has been facing is the stiffness of the car in relation to the terrain irregularities, which has hindered his ability to push the car to its limit. In an attempt to improve his performance, Zhou and the Sauber team have decided to revert back to a previous specification of the car. This change involves replacing all parts of the car to ensure a fresh start and address any potential issues. Zhou believes that this decision is the right choice and hopes that it will result in better results in the next race.
