Red Bull Racing have announced that Jaime Alguersuari will replace fellow Red Bull Young Driver Brendon Hartley as the reserve driver for Red Bull and Toro Rosso.
The 19 year old Spaniard, who became the youngest ever British F3 champion last year, is currently competing in the World Series by Renault. His first race in his new role will be the German Grand Prix at the Nurburgring on July 12.
Brendon Hartley will now concentrate on his own racing programme in the European F3 series.
