McLaren has signed 14-year-old kart racer Nyck de Vries for the team's young driver development program.
The Dutch driver will be managed by Anthony Hamilton, Lewis' father, and the Hamilton Management Group throughout his racing career in different categories.
"McLaren has a long-held commitment to assisting young talent – we believe it's part of the responsibility of the motor racing community to encourage and nurture junior racers, and we are committed to doing just that," said team boss Martin Whitmarsh.
"Nyck appears to be a very exciting prospect, and we are looking forward to assisting his junior career, providing him with the support and training he requires to succeed."
De Vries added, "My visit to the McLaren Technology Centre has been a fantastic experience and I am very honored and grateful for the support of McLaren in helping to develop my career. The resources they have are incredible, and I believe they'll be able to provide me with the perfect framework for improving my skills, my fitness and my motorsport experience."
McLaren said it will issue further details on its full young driver program next month.
