Jolyon Palmer will contest the final three first practice sessions of the season for Lotus as he continues preparations for his Formula 1 race debut with the team in 2016.
The 2014 GP2 champion, who has served as Lotus's reserve driver for this year, will partner Pastor Maldonado next year, taking Romain Grosjean's seat following the Frenchman's move to newcomer Haas.
Palmer has already taken part in 10 of 15 first practice sessions this season, each time replacing Grosjean.
He also completed two days of in-season testing for the Enstone-based team.
The Briton will now participate in the opening 90-minute session on Friday at the Mexican Grand Prix as well as in Brazil and Abu Dhabi next month.
