Sauber confirms new chassis for Gutierrez
Gutiérrez was tipped into a roll during last weekend's Bahrain Grand Prix and the Mexican, who was taken to hospital for precautionary checks, will receive a new chassis while the monocoque from the accident is being repaired.
Gutiérrez is hopeful that the minor upgrades to the Sauber C33 will enable the team to make progress in China.
"Looking back to the last three races, my performance will help me to get the maximum out of the car, in both, qualifying and the race," he said. "With the updates on the car, I hope we can increase our level of competition so we can achieve better results."
Neither Gutiérrez nor Sauber team-mate Adrian Sutil has scored a point so far in 2014 but the German believes that the characteristics of the Shanghai circuit should aid the team's progress.
"On this track a good balance for the car and a lot of grip on the front axle is needed," he said. "I believe the layout should be a good fit for the C33. I am positive about the weekend. We have to look forward, and every future race will move us furthermore up to the front."
