Mercedes team principal Toto Wolff has warned Ferrari that the straight-line advantage they held at the Canadian Grand prix may not translate to similar success at this weekend' French Grand Prix, despite similarities between the circuits in Montreal and Le Castellet.
The Scuderia's powerful engine in the SF90 helped Sebastian Vettel take pole in Canada, and cross the finish line first, although Lewis Hamilton inherited the victory through a time penalty for the German.
It continued the Silver Arrows' clean sweep of 2019 so far, with Hamilton and Valtteri Bottas sharing the seven victories so far this year five to two.
Hamilton came close to not starting the race in Canada as a race-morning rebuild was required on his car and Wolff says the panic of that moment will refocus minds in France.
"Canada was something of a wake-up call for us," Wolff said.
