Daniel Ricciardo is set to take grid penalties for the Canadian Grand Prix after Red Bull confirmed they will have to replace the MGU-K, which failed en-route to his win in Monaco.
As early as lap 18 Ricciardo reported a loss of power, causing the Australian to lose around 160hp from his Renault power unit, which allowed second-placed Sebastian Vettel to close in on the race leader.
For the remainder of the race, Ricciardo's pace dropped off but due to the nature of the Monte Carlo circuit, he was able to fend off the Ferrari of Vettel and Mercedes' Lewis Hamilton to clinch a seventh career victory.
“He will definitely be taking some penalties in Montreal, we haven’t heard at the moment just how many,” chief designer Adrian Newey told Reuters.
"One of the things there is whether the battery was damaged or not in Monaco, so until we know that from Renault we don’t know exactly what we’re facing.
"The [MGU] K is definitely a penalty."
There were rumours circulating after the Monaco Grand Prix where it was claimed Renault believed the MGU-K was in a salvageable state, however, Newey laughed off any such suggestion.
"I rather doubt it," added Newey, "considering it caught fire and was a burnt out, charred wreck. I would be somewhat surprised at that one."
After suffering the first MGU-K failure in Bahrain and the latest failure in Monaco, this means Ricciardo will take his third component in Montreal.
The 2018 technical regulations allow three power units per season but only two MGU-Ks per driver, this includes two energy stores and two control units without racking up a 10 place penalty for the next race.
