2025 F1 engine parts utilization: reliability turns into key issue as groups method PU limits


After 4 Grands Prix out of a 24-race calendar (plus the Dash), the reliability scenario is beginning to get attention-grabbing.

Yesterday, the FIA confirmed that, for the Saudi Arabian GP, all Pink Bull Powertrains-powered drivers – particularly Pink Bull and Racing Bulls – concurrently changed 4 energy unit parts: ICE (inside combustion engine), TC (turbocharger), MGU-H, and MGU-Ok. This mass alternative is solely authorized (because it includes the second of the 4 parts permitted for practically all parts), however it raises various warning bells inside RBPT.

Not like different engine producers, Pink Bull-associated groups are the one ones to have changed so many components concurrently this early, at simply the fifth spherical of the season. It’s onerous to assume it’s only a coincidence: the acute warmth in Jeddah and knowledge gathered from sensors on the finish of the earlier race could have prompted engineers to keep away from dangers and make early replacements. Nonetheless, the frequency of those interventions means that some facet of thermal administration or mechanical reliability wants nearer consideration, particularly since any additional alternative of both the management electronics or batteries will end in a 10-place grid penalty for all 4 RBPT drivers (George Russell can also be in the identical scenario together with his Mercedes).

As a result of a mixture of reliability issues, rain-related crashes in Australia, incidents in China, and points throughout apply classes in Japan, Oliver Bearman, Jack Doohan, and Liam Lawson had already used the second of the 4 obtainable energy models. With at present’s replacements, Jack Doohan and Liam Lawson are successfully approaching three, whereas Gasly now reaches two.

Amid a very difficult begin to the season, there may be excellent news from Ferrari, which, like McLaren, Aston Martin, Sauber, and Williams, has not skilled any reliability points.

With such an extended championship, automotive reliability shall be an important issue within the struggle for the World Championships, particularly because the rules restrict what number of parts might be changed on a automotive earlier than grid penalties are utilized. Specifically, energy unit components and people associated to the gearbox and transmission are intently monitored.

Based on the rules (Article 28.2), in the course of the 2025 season, a driver could not use greater than 4 ICEs, 4 MGU-Hs, 4 MGU-Ks, and 4 turbochargers (TC), 2 batteries (ES), 2 management electronics (CE), and eight exhaust techniques.
