Lotus has confirmed that Jolyon Palmer will make his Formula 1 debut in 2016, replacing Haas-bound Romain Grosjean alongside Pastor Maldonado.
Palmer, 24, won the GP2 title in 2014 and has occupied the position of test and reserve driver at the Enstone outfit this year, taking part in 10 Friday practice sessions and numerous tests in the E23 Hybrid.
"I’m obviously delighted that I’ll be racing in Formula 1 next year," he said.
"Lotus gave me a tremendous opportunity this season and I thank them for assisting my development to a level where they have put their trust in me for a crucial season in their evolution.
"I’ve enjoyed and learned a lot from my year as third and reserve driver so I’m looking forward to putting this into practice as a race driver in 2016. I can’t wait for next season to get underway."
Lotus boss Gerard Lopez praised Palmer for his approach this season and says he deserves his graduation.
"We’ve seen Jolyon’s hard work and talent this season in the way he’s approached his third driver role and he is a really popular choice for the team," he explained.
"As well as having a great future ahead of him behind the wheel, Jolyon is an intelligent and highly marketable asset to the team. He deserves this opportunity, and everyone at Enstone is excited to see what he can achieve next year."
