Jaime Alguersuari will become the youngest ever Formula One driver at this week's Hungarian Grand Prix after Toro Rosso confirmed he would pilot the team's second car
The 19-year-old Alguersuari replaces sacked Frenchman Sebastien Bourdais.
Team boss Franz Tost said, "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 one environment," he said.
Prior to moving to F1 last year, Bourdais won four successive Champ Car championships in America between 2004 and 2007. In 2002, he won the F3000 title, which is the equivalent of today's GP2.
Alguersuari replaced New Zealand's Brendon Hartley as Red Bull's reserve driver earlier this month.
