Mercedes driver Lewis Hamilton has admitted he expected his power unit to die during the Canadian Grand Prix after experiencing problems within the first ten laps of the race.
Hamilton reported to the team on Lap 7 of the race that he was having inconsistencies with the power output from his Mercedes unit.
The defending Formula 1 World Champion said that he suffered from engine overheating issues throughout the race too.
“I couldn’t get the temperatures down, so I just thought it was going to fail,” Hamilton said to media after the race, where he finished in a lowly P5.
Hamilton was not running a new specification power unit in Canada as the introduction of Mercedes’ upgrades has been delayed to next fortnight’s French Grand Prix.
This left him to run a power unit mostly comprised of parts that have been in use since the season-opening Australian Grand Prix.
“Every single lap I was waiting for the power to just drop away and disappear,” Hamilton said.
Hamilton ran most of the first stint in fourth but dropped back to fifth after being overcut by Daniel Ricciardo during the pit stops.
After leading from start to finish, Ferrari’s Sebastian Vettel won the Canadian Grand Prix.
The result cost Hamilton the lead of this year’s championship, with Vettel inheriting a one-point advantage.
“Ferrari have been doing a slightly better job and brought a better package,” Hamilton said.
Vettel’s win in Canada was the 50th of his career.
It was Ferrari’s first win in Montreal since Michael Schumacher took top honours in 2004.
“The season is still so long and there are many races ahead,” Vettel said.
Hamilton was pleased to have finished the race in Canada and said he “could have lost a lot more points today.”
