Sauber have finalised their driver line-up for next season
Sauber have named Mexican Sergio Perez as Kamui Kobayashi's driving partner for next year's Formula 1 season.
The 20-year-old won four races to finish second in this year's GP2 series and was the 2007 British F3 champion.
Perez will become the first Mexican driver in Formula One since Hector Alonso Rebaque between 1977 and 1981.
"Sergio has been on a continuous upward curve over the past few years," said team principal Peter Sauber. "I look forward to working with him."
Perez, who began kart-racing at the age of six, became the youngest GP2 race winner at the age of 18.
He said: "Formula 1 is the dream of every young racing driver and now this dream is about to come true for me.
"Although I'm very much aware that this is also a big challenge and responsibility, I'm happy to accept that and am proud to be representing my country in the highest category of motor-racing."
Sauber dropped Pedro de la Rosa last month, and installed veteran Nick Heidfeld as their driver for the final five races of the season.
The Swiss team, currently eighth in the 2010 constructors' standings with 27 points, also announced a partnership with Mexican telecommunications giant Telmex, owned by billionaire Carlos Slim.
Perez has been driving for the Escuderia Telmex team in GP2.
