Mercedes chances of maintaining its 100 percent win rate in Montreal just got stronger with confirmation it will be introducing an engine upgrade this weekend in Canada.
Mercedes is the last engine manufacturer to update its engine this season, with rivals Ferrari, Renault and Honda having already implemented upgrades at previous rounds.
Mercedes' new-spec power unit will also be supplied to customer teams Racing Point and Williams.
The update comes at a venue known for the power-sensitive nature of its track.
Earlier this week, Mercedes boss Toto Wolff expressed his concerns over his team's potential performance at the Circuit Gilles Villeneuve given the track's characteristics.
"In the past six races, we were very strong in the corners but lost time on the straights," said the Austrian.
"This will make Canada a huge challenge for us as the track characteristics could favour our opponents - there are many long straights, and fewer corners in which to make up laptime."
Something tells us Toto was being just a tad conservative in his assessment. Perhaps even sarcastic…
