Mexico's Esteban Gutierrez will compete in a second straight Formula One season after being confirmed in Swiss-based Sauber's driver line-up, the team said in a statement Saturday.
The 22-year-old driver will team up with Germany's Adrian Sutil, who has come over from Force India and will replace countryman Nico Hulkenberg.
Russian Sergey Sirotkin will be Sauber's new test driver.
The team also said it renewed its sponsorship deal with Mexican telecom company Telmex.
Gutierrez was the top F1 rookie in 2013, finishing 16th in the Drivers' standings, while Sauber ended last season in seventh place in the Constructors' standings.
Sauber's director, Monisha Kaltenborn, said on the team's Web site that Gutierrez is "a talented young racing driver" who made strides during his rookie season.
"Often the results didn't fully reflect his performances. I am confident Esteban will be able to use his experiences to gain results," Kaltenborn added.
"It was a steep learning curve last season, but by working closely with the team I was able to improve continuously. It will be my fourth year with the team, the second as a racing driver, and I feel comfortable in taking the next step," Gutierrez was quoted as saying.
"The technical challenges in 2014 will be massive. Therefore it will be even more important to know well the people you are working with. I will do my very best to improve even more and support the team the best way I can." EFE
