McLaren announced yesterday the Dunedin driver and team-mate Tanner Foust were leaving the team following the completion of this year’s Extreme E series, after their contracts were not renewed.
Gilmour said it had been "unbelievably special" being part of McLaren, joining the team for their inaugural race last season and making history as their first female driver.
"I always just enjoyed it for what it was and knew it was never going to be forever," Gilmour said.
"I really enjoyed all the special things I got to do and to be part of McLaren’s history and I hope that in the future I can still be involved with them in an ambassador-type role.
"I’m grateful for the team’s incredible support and for the unforgettable highlights we enjoyed together.
Gilmour and Foust secured two second-placed finishes during their time, in Uruguay last year and in Scotland earlier this year.
She missed the final leg of the series last weekend, withdrawing following her high-speed crash during a practice session in Sardinia in September.
Racing in some of the world’s most extreme locations in Saudi Arabia, Chile and Uruguay had been amazing.
But the moments from out behind the wheel meant just as much, including being involved in various events and celebrating 60 years of McLaren this year.
"Racing Extreme E was part of it, but it was actually just being part of McLaren was probably the real highlight, and all the people I met, and experiences I had," Gilmour said.
Her focus would be on rallying in New Zealand next season and hoping more overseas opportunities could arise in the future.
