Buemi has been given a second chance to prove his ability in F1
Swiss driver Sebastien Buemi will stay on with the Toro Rosso team in 2010.
The 21-year-old has been given a second chance to prove his potential after scoring eight points to finish 16th in the championship in his debut season.
Team-mate Jaime Alguersuari is also expected to stay with Toro Rosso but a spokesman for the team was unable to confirm the Spaniard's position.
"We have re-signed Buemi for next season, but we have not yet signed Jaime," a spokesman told BBC Sport.
Buemi revealed his new contract himself in an interview on Swiss television on Sunday.
"I had some contact with other teams because of my good results at the end of the season," he told the Television Suisse Romande programme Sport Dimanche.
"Toyota could have been a possibility because they had not yet hired any drivers. That was not the only one, and anyway I was always talking with Red Bull. Finally I signed with Toro Rosso for 2010."
We have to stick to the philosophy of giving young drivers a chance
Toro Rosso team principal
The team confirmed the deal when contacted by BBC Sport on Monday.
Team boss Franz Tost effectively confirmed that Alguesuari would also be kept on in an interview with Autosport.com.
"Dietrich Mateschitz bought this team to give young drivers a chance, and this is our philosophy," Tost said.
"We have to stick to this philosophy, and I'm quite confident that from the middle of next year onwards we will have a good driver line-up, because then Alguersuari will know all the tracks, and Buemi is increasing his performance already. The last few races were quite good.
"Alguersuari is also improving his performance, and so far I'm quite optimistic about the future."
Buemi's best results were two seventh places, earned in the first race of the season in Australia and the penultimate grand prix in Brazil.
Toro Rosso used effectively the same car as sister team Red Bull, who won six grands prix in 2009 with drivers Sebastian Vettel and Mark Webber.
Despite that, neither Buemi nor Alguesuari were able to match Toro Rosso's performances of 2008, when Sebastian Vettel won the Italian Grand Prix in the middle of a superb run of form in the second half of the season.
Tost said he was not worried about the pair's propensity for crashes in the final few races of the season.
"The crashes are part of the game," he said. "A young driver needs to find the limit of the car. I call it the 'crash period', and it's as important in this learning process and gaining experience as anything else.
"Therefore for me it's obvious that a driver sometimes has to crash. If he is a young driver he has to learn the limit of the car - I don't have a problem with this."
