For the opening round of the European leg of the 2025 F1 season, only several drivers have elected to take fresh power unit components at the Autodromo Enzo e Dino Ferrari.

For the 12th year running, the 2025 F1 cars are powered by V6 hybrid turbo power units with 1.6-litre engines. This season represents the last year the current engine configuration appears before being replaced by a new power unit formula in 2026.

Current F1 power units feature seven elements: the internal combustion engine (ICE), motor generator unit-heat (MGU-H), motor generator unit-kinetic (MGU-K), turbocharger, energy store (ES), control electronics (CE) and exhaust.

Over the course of the 2024 season, a driver may use no more than four ICEs, MGU-Hs, MGU-Ks and turbochargers, two energy stores and control electronics, and eight of each of the four elements that make up a set of exhaust systems (comprising primaries left-hand side, primaries right-hand side, secondary LHS and secondary RHS).

At the start of the weekend, Haas announced that they equipped Oliver Bearman’s car with a raft of fresh power unit components.

The British driver received a new internal combustion engine, turbocharger, MGU-K, MGU-H and exhaust system.

At the same time, Alpine confirmed a fresh exhaust system, energy store and control electronics for Pierre Gasly while also revealing that Franco Colapinto will complete his first race with the French marque with a new control electronics.

However, the Enstone based outfit confirmed further new components for its drivers on Saturday: a new MGU-K for Gasly, and a fresh internal combustion engine, turbocharger, MGU-K, MGU-H and exhaust system for Colapinto.

Following his heavy crash in qualifying, Red Bull elected to equip Yuki Tsunoda’s RB21 with a host of new components: internal combustion engine, turbocharger, MGU-H, MGU-K, energy store, control electronics and exhaust system, meaning that the Japanese driver has received an all-new power unit.
