Wolff not expecting anymore major updates for the W10

Toto Wolff has admitted he isn't expecting anymore updates for the W10 this season, as Mercedes look to see out the season, retain their titles and prepare for the 2020 season.

Mercedes have been streaks ahead of everyone for most of the season, but have had a slight blip with Ferrari developing a competitive car which has seen them claim three-race wins. However, normal service was resumed in Russia with Lewis Hamilton and Valtteri Bottas securing the team's first one-two since Silverstone.

With the title all but wrapped up thanks to their early season form, Wolff has admitted no more big updates are planned but there will still be some fine-tuning.

"That's how we planned it," Wolff revealed to the press in Russia.

“It is a matter of deploying and spending your resources correctly, partly with 2020 as a prospect. We have thought very carefully about that."

Wolff did reveal though that there would be updates at the Japanese Grand Prix because the team are "curious". Wolff added that the biggest changes to their car were made before the summer break.
