Fernando Alonso anticipates Honda's new turbocharger will aid its energy harvesting and therefore manage power deployment better than the previous configuration to give him a stronger overall race pace rather than outright extra speed.

Honda is set to introduce an updated turbo after spending two development tokens ahead of the Canadian Grand Prix, its first of this season, and after extensive testing Alonso is confident the part will improve the power unit's energy management.

"I think it's just an update on the power unit with a new turbo that will allow us to have a little bit more harvesting from the engine," Alonso said. "That's always a good thing, but it's not necessarily more power.

"Let's say for a race situation it will help a little bit in managing the batteries or deploying a little longer on the straights. It's not a big difference in qualifying, but let's hope so for the race."

With Circuit Gilles Villeneuve's demanding high speed straights, McLaren is expected to struggle against its rivals which could dent Alonso's recent resurgence in the past two races. Despite this, the McLaren driver is targeting a third straight Q3 berth in qualifying and hopes for points to maintain his momentum.

"I don't think we have a specific target to achieve here," he said. "We want to do our best and it will be a good test on completely different circuit to Barcelona and Monaco where the power effect is a little bit higher here.

"Hopefully we can still score points, be in Q3 again for the third consecutive time and these sorts of things will become a normality."
