Kamui Kobayashi will turn out for Sauber in 2011, the Swiss team have confirmed.
The Japanese driver burst on to the scene in closing stages of last season, replacing the injured Timo Glock at Toyota and immediately impressed, finishing sixth in the final race of the year in Abu Dhabi.
The 24-year-old's signature was secured by Sabuer for the current season, and he has repaid the team with 21 points thus far.
"We enjoy having our rookie as part of the team - both as a driver and a person," said team principal Peter Sauber.
"We never had any doubts about working with him again in 2011," explained team boss Peter Sauber.
"Kamui has definitely fulfilled our expectations in terms of his speed and fighting spirit. Plus, his work with the engineers and his technical understanding has also developed very well.
"The experience he has built up over his first full season in Formula One will certainly stand him in good stead for 2011. And our aim is to give him a fast and reliable car from the outset next season."
Kobayashi expressed his delight at securing his immediate future, adding that he was confident the team would improve next year.
"We had a very difficult start to the season, but we've worked together to pull ourselves out of that situation," said Kobayashi.
"I feel very much at home in Peter Sauber's team and am very pleased we'll be working together again in 2011
"However, for now I'm focusing one-hundred per cent on this year. There are still six grand prix weekends to go in 2010, and we'll be hoping to make up more ground," he concluded.
