Spanish Jaime Alguersuari joined Toro Rosso to become the youngest ever Formula One driver at 19 on Sunday.
The 19-year-old will replace sacked Frenchman Sebastien Bourdais until the end of the season.
The reigning British Formula Three champion will make his debut for the Italian outfit at the Hungarian Grand Prix on July 26.
"While Formula One will be very new to him, as a driver who has come up through the ranks of the Red Bull Junior Team young driver programme, he knows his new team-mates well," Toro Rosso added in a statement.
Alguersuari has competed in 118 races from junior karting to Formula 3 and Formula Renault. He has had 17 victories and 36 podium finishes.
Bourdais was sacked last week following lackluster performances in this year's Formula One campaign. The 30-year-old Frenchman scored just six points from the 27 Grands Prix in which he competed.
