Mercedes have announced they will have an upgraded power unit at the Canadian Grand Prix for all the cars powered by the Silver Arrows team's engines on the Formula 1 grid.
Mercedes are now ahead of Ferrari and Red Bull Racing in both the Drivers' and Constructors' championships, but have faced a stiff challenge in all the races thus far.
"If the others are bringing upgrades and are using fresh engines - particularly with how close we are on performance - we won't be in a position to fight I don't believe", he said.
As a result, The team will now race with a below par engine at a circuit where power is important.
"I hope I've had my run of back luck for the whole here and things will go smoothly from now on". That is my only concern. "I want to win races and I'm sure it will come".
Even with a diminished power unit Hamilton can not be overlooked on one of his favourite tracks.
The 33-year-old Briton, who loves spending time in North America where he has additionally won the United States Grand Prix four times, arrived in Montreal on Tuesday night after visiting California, reportedly to check on his dogs Roscoe and Coco, and NY.
It is where he won his first Grand Prix in 2007 and a circuit he has dominated, winning the last three races and four of the last six.
Mercedes lead Ferrari by 22 points in the constructors' standings going into the Canadian Grand Prix while Hamilton is ahead of Vettel by 14 in the drivers' equivalent. I can't tell you why it is always the case.
"Each driver has their strengths and weaknesses and there are 21 circuits it is impossible to be ideal at every one".
