As widely expected, European F3 champion and McLaren junior Lando Norris has been handed the role of test and reserve driver for the Woking-based outfit in 2018.
Norris has been a member of the McLaren Young Driver programme since the start of 2017, and today’s announcement crowns a hugely impressive 12 months for the 17 year old.
Last December, he won the prestigious McLaren Autosport BRDC Young Driver Award, an accolade renowned for putting promising young talent on the motorsport map.
In August, he impressed hugely on his Formula 1 test debut at the Hungaroring, spending a day developing the MCL32.
"I’m so excited to be joining McLaren as test and reserve driver for 2018," said the 17-year-old.
"The last 12 months have been an incredible journey for me – I’ve enjoyed every single minute – and this is just an amazing way to bring the year to an end.
"I’m really looking forward to helping the team, starting next week with the tyre test at Interlagos, and I will work harder than ever to learn and develop across the next year.
"I have two excellent teachers in Fernando and Stoffel, and I will do my best to help with the team’s efforts to get back to the front.
"I’m still working hard to finalise my own racing programme for 2018 – we’re close on a number of different fronts, but not quite there yet. I hope to be able to announce something shortly."
McLaren boss Zak Brown has been impressed with his young driver's skills from the outset, but was particularly amazed at the speed he showed in Hungary's in-season test last summer.
"Lando is an outstanding young talent. Today’s announcement is thoroughly deserved, and underlines the incredible high regard in which we hold his abilities.
"By winning last year in Formula Renault, triumphing in the McLaren Autosport BRDC Young Driver Award, and then showing the speed and consistency needed to win the European F3 championship, he is undoubtedly carving himself a reputation as one of the very best up-and-coming single-seater drivers in the world.
"His summer test for McLaren was also remarkably impressive, and was further proof that he is ready to step up and take on a role of this size, scope and responsibility.
"At McLaren, we are all extremely keen to help him achieve his goal of racing in Formula 1."
