Brendon Hartley has said that he is looking forward to switching from Renault to Honda power for 2018.
Since joining Toro Rosso late this year, the Le Mans winner has been struggling for laps due to constant Renault reliability issues.
New Zealander Hartley says that he is therefore not worried about moving to McLaren's troubled works engine partner Honda for next year.
"I think in the past two races we've had no reliability at all from the engines we have," the 27-year-old rookie told Russia's Championat.
"At the same time, I am sure that working with Honda is a great opportunity for myself and the whole team and a very positive moment."
Meanwhile, he said that he has been fielding "a lot" of questions recently about Daniil Kvyat, the driver he is replacing at Toro Rosso for 2018.
"I guess I'm not the most popular in Russia right now," Hartley said, "but seriously it's hard for me to comment. I didn't make the decision, and in formula one we know these decisions are not always easy.
"It's a very difficult question, but from my side I can only say that I'm glad to get a second opportunity here."
The 2017 calendar concludes with the Abu Dhabi Grand Prix on Sunday.
