Norris takes Belgian GP grid penalty after Mercedes unit failures
Reigning champion Lando Norris will start Sunday's Belgian Grand Prix no higher than 11th after McLaren was forced to take a 10-place grid penalty due to repeated power unit failures from supplier Mercedes-AMG.
Lando Norris will take a 10-place grid penalty at Sunday’s Belgian Grand Prix after McLaren fitted his car with a fourth power electronics unit, exceeding the three-unit seasonal limit mandated by Formula 1 regulations.
The penalty exposes the operational toll of repeated component failures from engine supplier Mercedes-AMG High Performance Powertrains. Outlining a season of electrical issues, McLaren confirmed that Norris’s first unit suffered a terminal failure in China. A second unit required remedial work after issues in Japan, and despite being repaired, subsequently suffered another terminal failure during practice in Monaco.
The team is now fitting a fresh fourth unit to take advantage of recently introduced reliability fixes from Mercedes. McLaren stated: "While the power electronics unit we installed in Japan, and have used in every session since Miami, has worked reliably, Mercedes-AMG High Performance Powertrains has since introduced a series of reliability fixes to their new power electronics systems."
McLaren acknowledged that installing these upgraded components requires absorbing a sporting penalty. The team said: "We have chosen to do this in Belgium, a circuit where overtaking is relatively more prevalent, as opposed to the following two events in Hungary and Zandvoort. We now plan to use this fourth power electronics unit for the remainder of the season, in order to maximise reliability while minimising sporting penalties on Lando."
The strategic penalty reflects the wider supply chain complexities in modern motorsport. Mercedes first ran its updated, more reliable power units two races ago in Austria, supplying customers Alpine and Williams with the new specifications at the last round in Silverstone.
McLaren, however, was barred from taking the upgraded internal combustion engines earlier in the season. Because both Norris and teammate Oscar Piastri failed to start the Chinese Grand Prix due to the initial power unit failures, the team did not reach the required mileage limits on those components. Both drivers are finally set to take the fresh internal combustion engines this weekend in Belgium without incurring additional grid penalties.
The engineering disruptions have severely hampered McLaren’s competitive standing. Norris is currently fifth in the Drivers' Championship after nine rounds. He sits 82 points behind series leader Kimi Antonelli, with McLaren unable to consistently challenge the dominant Mercedes and Ferrari outfits during his reign as world champion.
