Red Bull tech supremo Adrian Newey has since confirmed the defective part on Ricciardo’s car will definitely need replacing out of schedule, which will incur an automatic grid drop under F1 rules.
The Honey Badger fended off Sebastian Vettel to claim his first Monaco Grand Prix victory last time out, but did so without the use of the MGU-K after the power unit component – which recovers energy under braking and redeploys it to the power train – failed with more than half the race to go.
“He will definitely be taking some penalties in Montreal, we haven’t heard at the moment just how many,” Newey told Reuters. “One of 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. I rather doubt it (can be reused), considering it caught fire and was a burnt out, charred wreck,” he said. “I would be somewhat surprised at that one…”
Formula 1 power units are split into six components. Each driver is limited to three internal combustion engines, turbochargers and MGU-Hs and only two MGU-Ks, energy stores and control electronics for the season.
“It’s about 1% (more power), which is a tenth of a second so it’s worth having but it’s not a make or break,” he said.
