Although the German car manufacturer is coming off the back of a win in Russia, it knows its success there was down to good timing with a virtual safety car pitstop.
“We’ll bring some minor upgrades to the car in Japan which will hopefully help us take a step in the right direction.
“However, we know that we need to extract absolutely everything from our car and the tyres if we want to be able to challenge for a win.”
Wolff said after the Russian Grand Prix that the team’s switch of focus to 2020 led to the development of this year’s car to slow down, a factor that has contributed to Ferrari becoming the team to beat.
The Italian squad, meanwhile, believed that its form has been boosted by bringing forward development work planned for next year.
