Hamilton set to receive engine boost to destroy Ferrari

Hamilton on hearing he will have even more power

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 peerless Mercedes team have dominated the new campaign, finishing first and second at all but one of the opening six rounds.

The Briton, with four victories under his belt, is 17 points clear of team-mate Valtteri Bottas and 55 ahead of Ferrari's Sebastian Vettel in the championship standings.

And world champions Mercedes are poised to strike another blow to their rivals with the planned introduction of their first fresh engine of the season at Montreal's high-powered Circuit Gilles Villeneuve.

Mercedes will be the last of the front-running manufacturers to introduce its new-specification power unit this year, with Ferrari and the Honda-powered Red Bull team having already introduced their first updates in Spain and Azerbaijan respectively.

Drivers are only permitted to use three engines without penalty throughout the 21-round campaign.
