Who will race with fresh power unit components at the British Grand Prix?
Several Formula 1 teams have fitted fresh power unit components ahead of the British Grand Prix as they continue to manage their allocations under the sport's all-new 2026 engine regulations.
The 2026 season has introduced Formula 1's biggest power unit overhaul since the start of the hybrid era. While the new units retain six core elements—the Internal Combustion Engine (ICE), Turbocharger (TC), Exhaust system (EXH), Motor Generator Unit–Kinetic (MGU-K), Energy Store (ES), and Control Electronics (CE)—the removal of the MGU-H has significantly increased the importance of the MGU-K and battery system.
To ensure reliability across the record-length season while limiting costs, the FIA restricts the number of components each driver may use. Drivers are permitted four Internal Combustion Engines, four Turbochargers and four Exhaust systems, together with three MGU-Ks, three Energy Stores and three Control Electronics units before grid penalties apply.
Ahead of Sunday's race at Silverstone, several drivers have taken fresh components within their allocated limits.
Carlos Sainz, Esteban Ocon, Oliver Bearman, Pierre Gasly, Franco Colapinto, Sergio Perez and Valtteri Bottas have all received new Internal Combustion Engines and Turbochargers.
Sainz and Gasly have also fitted new Exhaust systems, while fresh MGU-K units have been installed on the cars of Sainz, Ocon, Bearman, Colapinto, Perez and Bottas.
Elsewhere, Arvid Lindblad, Ocon and Bottas have received new power unit ancillary components.
The only driver to exceed his permitted allocation is Lance Stroll. The Aston Martin driver has fitted a new Energy Store and new Control Electronics beyond his seasonal allowance, triggering automatic grid drop penalties for the British Grand Prix under the FIA Sporting Regulations.
With the majority of today's changes remaining within the permitted component allocations, teams are taking the opportunity to refresh key elements of their power units at one of the fastest and most demanding circuits on the calendar.
Silverstone's high-speed corners and sustained full-throttle sections place significant thermal and mechanical loads on the power unit, making careful component management a crucial part of each team's championship campaign.
