Jolyon Palmer will leave Renault after Japanese GP
The British driver will not drive for Renault in the last four races.
Jolyon Palmer has announced that Sunday's Japanese Grand Prix will be his last race with the Renault F1 Team, on Instagram.
The 26-year-old was already to be replaced by Carlos Sainz Jr in 2018, with rumours floating that he may have to vacate the seat from the Malaysian race itself.
That, however, did not happen, but negotiations still went on, which now comes into fruition with the forthcoming announcement.
"Tomorrow's Japanese GP will be my last race for Renault. With my grid penalty I'll be starting near the back but I will be giving it my all as always. Thanks everyone for the support during the last 2 years, it means a lot!" he wrote.
"The Japanese Grand Prix will be my last race for Renault. It’s been an extremely challenging season and I’ve been through a lot in the last three years, but it’s been a tremendous journey overall with the team," he said in the release.
"I can look back proudly at the performance in the second half of last season, my first point in Malaysia and of course reaching a career high of sixth place in Singapore this year.
"I wish the team all the best for the future. My immediate focus is now on achieving the best possible result in the Japanese GP, and then I can assess my options for the future.”
Renault will draft in Sainz from Austin onward after Red Bull and Toro Rosso agreed to an early release, with the Faenza-based team bringing back Daniil Kvyat to partner Pierre Gasly - also confirming that Gasly will miss the Super Formula finale, where he could have secured the title.
"First of all I would like to thank Toro Rosso and Red Bull for allowing me the possibility of finishing this season with Renault Sport Racing," said Sainz.
"More specifically, I really want to thank all my engineers and mechanics for their support and tremendous work throughout these years. Toro Rosso is made up of a fantastic group of people and I wish them only the best for the future.
"On my side, I will definitely do my very best in tomorrow's race... this would be the best possible send-off! Additionally, competing in these last four races with Renault gives me a good opportunity to get to know the team and the car earlier than expected. I am looking forward to start working with them."
Toro Rosso's boss Franz Tost commented: "I would like to thank Carlos for all his efforts over almost three Formula 1 seasons.
"He always did his very best, demonstrating an excellent attitude and commitment to his work, which helped him and us to get some great results during that time.
"Therefore, on behalf of everyone at Toro Rosso, I wish him all the very best with his new team. We look forward to beating him on track!"
Renault's boss Cyril Abiteboul added: "I would like to thank Jolyon for his commitment to the team and his professionalism.
"Since Renault’s return to Formula 1, Jolyon has been highly dedicated in an evolving environment. He has shown great personal qualities and we wish him all the best in his future career.”
In the two years with Renault, Palmer has endured troubled run with only two points scoring races. This year's Singapore GP bringing his best result of sixth place.
It remains to be seen if Palmer stays in F1 for next season - the only possible chance for the British driver is with Williams.
