Mercedes and Ferrari drivers set to start with fresh power units at Montreal
Having grabbed a last-gasp pole position in yesterday's nail-biting qualifying session at Montreal, George Russell will race today with a fresh Mercedes power unit at Montreal.
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).
George Russell and his team-mate Andrea Kimi Antonelli will race with a fresh internal combustion engine, turbocharger, MGU-H, MGU-K and exhaust system.
Aston Martin's two-time F1 champion Fernando Alonso has also received new Mercedes PU components, including internal combustion engine, turbocharger, MGU-H, MGU-K and exhaust system.
Ferrari have also elected to mount fresh parts into Charles Leclerc and Lewis Hamilton's SF-25, including a new internal combustion engine, turbocharger, MGU-H, MGU-K and exhaust system.
Racing Bulls has equipped Liam Lawson' VCARB with a new internal combustion engine, turbocharger, MGU-H and exhaust system.
