New McLaren boss Jost Capito is expecting improvements in 2017.
The German, a fresh addition to the team after leading Volkswagen to three titles in as many years in the World Rally Championship, says that the improvements must come not just from Honda as they continue to develop their engine, but from McLaren themselves too.
"I expect improvement on the car from McLaren and a big step from Honda on the engine," he told BBC Sport. "It takes always a certain time to form a team with a new partner like this. McLaren and Honda were partners before but it was a long time ago.
He said that while it took time for both sides to understand eachother and develop the perfect working dynamic, with that now achieved, they can focus on moving up the field.
"All new people are involved and it takes a while for Honda to understand how McLaren works and for McLaren to understand how Honda works. I think this is now achieved," he said. "It is a very good partnership and the Honda guys understand more what is needed from the chassis side and we understand more what is needed from the engine side as well."
"I expect really not just the improvement of each but also the improvement of the overall relationship. So one plus one is not two - it should be three," he added.
