Montreal, Canada - Formula One champion Mercedes will continue to give its drivers equal treatment despite the emergence of Sebastian Vettel as Ferrari's clear title contender, team boss Toto Wolff said on Tuesday.
Championship leader Vettel has won three of the six races so far, finishing second in the rest, and scored nearly twice as many points as team-mate Kimi Raikkonen. Mercedes has also won three races but they have been shared between Lewis Hamilton, with two victories but now 25 points behind Vettel, and Valtteri Bottas.
Wolff said in a team preview of Sunday's Canadian Grand Prix: "We have two excellent drivers and we will hold true to our philosophy of letting them race each other to drive the team forward - even if sometimes it can be difficult because you can't always have the one who is ahead in the championship winning."
Hamilton, who was only seventh in the previous race in Monaco, has 104 points to Bottas's 75. Both Mercedes drivers have gone well in Canada in the past, Hamilton winning for the past two years at the Circuit Gilles Villeneuve and five times in total - making it his most successful circuit along with Hungary. Bottas has also been on the podium in Canada for the past two years, with his previous team Williams.
Hamilton told reporters in Monaco, where Ferrari finished first and second, that it was clear to him that the Italian team was favouring Vettel.
"It's clear to me that Ferrari have chosen their number one driver," he said. "They are pushing everything to make sure Sebastian will maximise on all of his weekends."
Hamilton added, however, that he saw no need to change Mercedes' approach.
"Valtteri has been doing a great job and I don't feel like we have to favour one over the other," he said. "We have to work collectively as a team more than ever before to beat the Ferraris in the Constructors' championship."
Ferrari leads champion Mercedes by 17 points in the Constructors' standings.
Wolff, who said in Monaco that the Mercedes were now the underdogs, acknowledged that it hurt.
"We have to fight with all that we are worth for every single win, pole position, podium finish and every point," he said. "You can no longer expect that when you look at a time sheet the two Mercedes cars will be right at the top."
