Toro Rosso have announced that Red Bull junior Sergio Sette Camara will test for the team at the forthcoming in-season test which follows the British Grand Prix next week.
The 18-year-old currently competes in the FIA F3 European Championship and sits seventh in the standings.
Camara thanked Red Bull for the opportunity, which will see the Brazilian in action on the second day, taking over from Carlos Sainz.
"I’m very happy and excited to be testing with Scuderia Toro Rosso," he said during a visit to Toro Rosso's factory.
"It's a great opportunity which I’ve worked very hard for and I’d like to thank everyone who has made this possible, especially Red Bull.
"This will be my first official Formula 1 test and I will make sure I do the best job possible as well as have fun – it’s not something that happens every day! Silverstone is a great track which I know quite well as I’ve already driven there before, so this will definitely help me on the day to focus on the car and all the new information without having to learn a new layout at the same time. I just can’t wait to drive out of the garage, it will definitely be a moment I will never forget!"
Team principal Franz Tost added: "Giving young drivers, mainly those from the Red Bull Junior Team, a real taste of Formula 1, is something we have become accustomed to doing at Toro Rosso.
"Personally, I find it fascinating to see how these youngsters adapt, not just to the extra power, downforce and braking of a Formula 1 car, but also how they react to the pressure of a day in the F1 spotlight.
"It provides a valuable insight into how they might progress in the future. Therefore I am pleased to welcome Sérgio to our team for the day and I hope that it will be a mutually beneficial experience."
