Jenson Button will miss qualifying for the Canadian Grand Prix after more engine trouble for Honda.
Fernando Alonso required an engine change on Saturday morning which saw the double world champion miss the majority of FP3, emerging with ten minutes of the session to go to complete his first laps. However, Alonso was limited to just three in total as team-mate Button duly stopped on track.
Button's problem is an ERS-related failure, and McLaren has confirmed the time it takes to investigate the issue and complete any work on the car will see Button miss qualifying.
Honda's woes this weekend come despite an update to the power unit, which has seen two development tokens used for what motorsport boss Yasuhisa Arai says is a combination of performance and reliability.
"Both, but not so much increasing the performance," Arai told F1i. "We prepared not only for this race but also for the future during the season. So we need to upgrade many parts and many components."
