Lewis Hamilton is set to receive a boost in his quest for the world championship, with Mercedes to unleash an upgraded engine for this week’s Canadian Grand Prix.
Hamilton’s team have dominated the new campaign, finishing first and second at all but one of the opening six rounds.
Mercedes will be the last team to introduce its new-specification power until this year.
Drivers are only permitted to use three engines without penalty throughout the 21-round campaign.
The good news for Hamilton comes in stark contrast to the troubles at Ferrari.
