He replaced Caterham F1 driver Kamui Kobayashi for a one-off race at the 2014 Belgian Grand Prix. He qualified 21st place, in front of teammate Marcus Ericsson, but his race lasted just one lap before a mechanical failure put an abrupt end to his F1 debut. He was invited to race again at the Italian Grand Prix, but declined as the team planned to run Roberto Merhi in the car for the first practice session, contrary to his desire to take part in all the available running due to his lack of experience.
