With the three-week summer time break slowly drawing to its finish, F1Technical’s senior author Balazs Szabo analyses what number of energy unit elements drivers nonetheless have for the rest of the season.
For the twelfth 12 months operating, the 2025 F1 vehicles are powered by V6 hybrid turbo energy items with 1.6-litre engines. This season represents the final 12 months the present engine configuration seems earlier than being changed by a brand new energy unit system in 2026.
Present F1 energy items function seven components: the inner combustion engine (ICE), motor generator unit-heat (MGU-H), motor generator unit-kinetic (MGU-Ok), turbocharger, power retailer (ES), management electronics (CE) and exhaust.
Over the course of the 2025 season, a driver might use not more than 4 ICEs, MGU-Hs, MGU-Ks and turbochargers, two power shops and management electronics, and eight of every of the 4 components that make up a set of exhaust methods (comprising primaries left-hand facet, primaries right-hand facet, secondary LHS and secondary RHS).
Disregarding the exhaust system which has not often pressured drivers right into a grid drop penalty, the vast majority of the sector has already exploited its total allocation.
Oscar Piastri, Lando Norris, Charles Leclerc, Lewis Hamilton, Yuki Tsunoda, George Russell, Andrea Kimi Antonelli, Lando Stroll, Fernando Alonso, Franco Colapinto, Ollie Bearman, Liam Lawson and Carlos Sainz have already exploited all of the elements of their allocation so far as the inner combustion engine, the MGU-H, MGU-Ok, turbocharger, power retailer and management electronics are involved.Actually, Bearman nonetheless has yet another recent power retailer to make use of within the remaining ten races.
Seven drivers have already acquired grid penalty for exceeding their allocation, together with Hamilton, Antonelli, Alonso, Colapinto, Lawson, who’ve used greater than 4 ICE, TC and MGU-H elements thus far in 2025.
Within the case of Hamilton, Antonelli and Alonso, the extra elements had been added to their pool on the Belgian Grand Prix as Ferrari, Mercedes and Aston Martin elected to hold out a tactical change after the British, Italian and Spanish driver suffered a dismal qualifying end result.
Curiously, there are drivers who nonetheless have recent components to make use of within the the rest of the season.
Max Verstappen, Gasly, Isack Hadjar, Alexander Albon, Nico Hulkenberg and Gabriel Bortoleto nonetheless have new elements – together with ICE, turbocharger, MGU-H and MGU-Ok – so as to add to their pool, which could yield some benefit within the last leg of the season when a number of drivers may serve a penalty for exceeding their allocations.
