Scuderia Toro Rosso has confirmed Spaniard Jaime Alguersuari will make his Formula 1 racing debut at the Hungarian Grand Prix this weekend.
The 19-year-old will become the youngest driver to participate in a grand prix in the history of the sport.
Alguersuari replaces Frenchman Sebastien Bourdais at the wheel of the second car, partnering Swiss racer Sebastien Buemi.
"I would like to thank Red Bull for giving me this great opportunity to race in Formula 1," he said. "Ever since I started racing this has been my dream and thanks to the Red Bull Junior Programme I will now realise my ambition of lining up on a Grand Prix grid.
"I am aware that I'm facing a very tough challenge, because coming into Formula 1 is never easy, coming into Formula 1 in the middle of a season is even harder and doing so without any testing is really difficult. But already I feel that I am getting great support from the team, who have quite a reputation for looking after rookie drivers."
Team boss Franz Tost said the Faenza-based squad was not expecting anything from the Spaniard.
"Red Bull's stated aim for Scuderia Toro Rosso is that, when possible, it should be used to provide a seat for products of its Young Driver Programme," he said. "We therefore chose Alguersuari as the most mature driver currently in the programme.
"I am well aware that over the next few months the team and Jaime will face a major challenge, especially because of the testing ban. But Red Bull is always ready for a new challenge.
"I do not expect anything from him for at least his first three races, during which he has to get used to the car, the team and to the Formula 1 environment."
