F1 engine supplier Renault will take stock of its recovery from an early-season technical crisis this weekend in Canada.

Ahead of the seventh round of the 2014 season, the French marque announced it will “complete the process” of fixing its troubled turbo V6 power unit in Montreal. “At the start of the season we said that we would be out of recovery mode and back on track from Canada onwards,” Renault track boss Remi Taffin said this week. “In the last four races we’ve introduced several new upgrades and we will complete the process in Montreal, effectively giving us the first full opportunity to see where we are versus the competition.”

Unlike Monaco, where ultimate engine power is not so important, Montreal’s Circuit Gilles Villeneuve is expected to particularly suit the field-leading Mercedes package. Taffin agrees that Canada is the “toughest challenge of the year so far” in terms of the demands on the engine. “Realistically we have to be humble,” he said, “but it will still be a very good test of how far we’ve come since the difficult winter testing period and how much work remains to be done.”
