McLaren has announced that Denmark's Kevin Magnussen will link up with Jenson Button as a Formula One driver for 2014.
Current McLaren driver Sergio Perez revealed on Wednesday that he would be parting with the British-based team at the end of the season, with Magnussen heavily mooted as his replacement.
And they confirmed on Thursday that the 21-year-old Dane, who drove for the team at the Silverstone Young Driver test in July, will fill the vacant seat.
Magnussen, son of former McLaren driver Jan, has impressed this year in the Formula Renault 3.5 World Series, clinching the title ahead of Stoffel Vandoorne.
And the youngster was delighted to have signed a deal with McLaren, declaring it was a dream come true.
"I'll put it simply: This team is the best," Magnussen said in a statement.
"It's been my dream to drive for McLaren ever since I was a small kid, and it's no exaggeration to say that I've dedicated almost every day of my life to achieving the goal of becoming a McLaren Formula 1 driver.
"I have an enormous amount of respect for everyone at McLaren, and I want to say a massive 'thank you' to everyone, but most of all to Martin and his senior colleagues, for giving me this chance. I won't let you down, guys!"
McLaren team principal Martin Whitmarsh was delighted with the addition, and says he has high hopes for the partnership between Magnussen and Button.
"Their confirmation is an important step for us as we continue to strengthen our organization ahead of the 2014 season," he said.
"Jenson's race-winning speed, intelligence and racecraft have long been a crucial advantage to McLaren, but it's his skill as a development driver and his peerless technical feedback that will be equally valuable as we make the transition into a new and complex technical formula during the winter and New Year.
"Kevin, too, is clearly very talented and very determined, and we therefore have high hopes for him. Moreover, every time he's tested our Formula 1 car, he's been very quick and very methodical, and his feedback has been first-class.
"Furthermore, the manner in which he won this year's World Series by Renault 3.5 Championship was truly outstanding, showcasing as it did not only his impressive natural pace but also his increasing maturity and ability to structure and manage a championship campaign."
