Stoffel Vandoorne has hailed his "fantastic" debut having tested a McLaren F1 car for the first time on Wednesday.
The McLaren protege was in action at the Circuit de Barcelona-Catalunya on Day Two of the two-day test, replacing regular driver Jenson Button.
With his day reserved exclusively for testing Pirelli's tyres, Vandoorne completed 136 trouble-free laps with a best time of 1:28.441.
"This has been a fantastic day for me: my first experience in a Formula 1 car, and a really great opportunity to get plenty of laps under my belt," said the 22-year-old.
"I want to say a big thank-you to the team - everyone has been incredibly helpful and positive."
Such was the Belgium driver's mileage on Wednesday that he accrued enough mileage to earn a Formula 1 Superlicence.
"It's also great to have been able to contribute to the test programme: 136 laps was a fantastic achievement, and it's great that it's earned me the right to be granted a Formula 1 Superlicence."
But it is now back to GP2 with ART Grand Prix and the Monaco race where Vandoorne is hoping to bounce back after a difficult time in Spain.
"Now my focus turns towards my next event - the GP2 races in Monte-Carlo next Friday and Saturday. I'm looking forward to bouncing back from a tricky weekend in Barcelona, and would love to get some great results in Monaco."
