The FIA has officially confirmed that McLaren will replace the power units of both Lando Norris and Oscar Piastri ahead of the Belgian Grand Prix at Spa-Francorchamps. This decision comes at a crucial stage of the 2025 season, with McLaren enjoying one of its strongest campaigns in years. The Mercedes-powered team has already claimed nine race victories, making them serious contenders in both the Drivers’ and Constructors’ Championships. By changing critical engine components now, McLaren aims to maintain its competitive edge as the title battle intensifies.
According to the FIA’s technical documentation, Norris and Piastri will each receive a brand-new internal combustion engine (ICE), turbocharger (TC), motor generator unit-heat (MGU-H), and motor generator unit-kinetic (MGU-K). These elements are vital for modern hybrid power units, influencing both raw speed and energy recovery efficiency. Aston Martin’s Lance Stroll will also undergo similar upgrades ahead of the Belgian round, indicating that multiple teams are taking strategic measures to ensure peak performance at Spa.
The Belgian Grand Prix, held on the demanding Spa circuit, is known for its combination of long straights and fast corners, putting engines under extreme stress. McLaren’s decision to introduce fresh components here is no coincidence—it maximizes the chances of strong qualifying results and race pace on a track where engine performance is crucial. With the team fighting at the front, such strategic updates could prove decisive in their championship campaign.
Norris and Piastri’s outstanding form this season underscores why McLaren is making this bold move. Norris continues to deliver consistent podiums and wins, while Piastri, in just his second full Formula 1 season, has established himself as a serious title threat. Their combined efforts have positioned McLaren as a formidable challenger to Red Bull, Mercedes, and Ferrari, marking a significant resurgence for the Woking-based team.
Strategically timing this engine change is also important under current FIA regulations, as teams are limited in how many power unit components they can use before incurring grid penalties. By opting for this refresh now, McLaren ensures that both cars have reliable and powerful engines for the demanding races ahead. Spa’s high-speed sections, like Eau Rouge and the Kemmel Straight, make fresh components invaluable for both performance and durability. With rivals like Max Verstappen pushing hard, every technical decision matters, and McLaren’s latest move could be a key factor in shaping the championship outcome.
