McLaren has confirmed that Honda youngster Nobuharu Matsushita has been appointed as its new test and development driver this year.
Matsushita placed ninth in his rookie GP2 campaign last year for ART, alongside eventual champion Stoffel Vandoorne, who acts as McLaren's reserve pilot.
Matsushita will remain with ART in GP2 this season and is set to conduct simulator duties for McLaren.
"This season I am ecstatic to be joining McLaren as a test and development driver," said Matsushita.
"To step into the world of Formula 1 fulfils a boyhood dream, and is a huge step forward in my career. I will do the utmost to help the race team on the track, by gathering data to feed back into the development and set-up of the car through simulator work.
"Last year’s GP2 Series season was a steep learning curve for me,” he added. “It was my first year racing in Europe – but, thankfully, my experiences with Honda’s young driver programme meant I was well prepared for the task ahead.
"As a GP2 Series driver, my sole focus for 2016 is to win the championship. I believe that I have the best package around me to succeed and reach my ultimate goal of becoming a Formula 1 driver."
