Power units: Who has taken fresh PU components for the Hungarian Grand Prix?

With the Hungaroring set to host the 14th race of the season, only four drivers have elected to take on new power unit components. F1Technical's senior writer Balazs Szabo reports from the Hungaroring.

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 2025 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).

Williams driver Alexander Albon has received a new energy store. It is his second unit this season, so he will need to complete the rest of the year with this new one and he is also allowed to use his previous one.

The London-born Thai driver has also taken a new control electronics just as Sauber driver Nico Hulkenberg and Haas racer Esteban Ocon.

With all drivers staying within their allocation for the current season, the changes have not triggered any grid-drop penalties.
