F1MATHS: How many power unit compontents have drivers used so far this season?

Regardless of the all-new energy items, mechanical reliability has been comparatively sturdy throughout the sphere within the first three races of the 2026 F1 season. F1Technical’s senior author Balazs Szabo delivers his newest anaylsis.

The 2026 System 1 season has ushered in essentially the most transformative energy‑unit laws because the hybrid period started, reshaping not solely how engines are constructed but additionally how groups should handle them throughout a file‑size calendar.

The brand new energy items retain the acquainted hybrid construction however with a dramatically altered steadiness between combustion and electrical energy. Every unit consists of six key components: the Inside Combustion Engine (ICE), the Turbocharger (TC), the Exhaust system (EXH), the Motor Generator Unit‑Kinetic (MGU‑Ok), the Power Retailer (ES), and the Management Electronics (CE).

With the removing of the MGU‑H, the MGU‑Ok now performs a much more central function, supported by the next‑capability battery and simplified turbo structure. These adjustments have elevated the thermal and electrical calls for on the system, making reliability administration extra vital than ever.

To maintain the season aggressive and stop extreme element swapping, the FIA has set strict utilization limits. Every driver could use as much as 4 ICEs, 4 Turbochargers, and 4 Exhaust units, together with three MGU‑Ks, three Power Shops, and three Management Electronics items.

Nevertheless, the 2026 guidelines introduce a brand new twist: one extra “bonus” allocation for every element class. This provides groups barely extra respiration room as they adapt to the brand new hybrid structure, however with 24 races on the calendar, the margin for error stays slim.

Three rounds into the season, the early patterns of element utilization reveal a discipline that has largely averted main reliability scares. Most drivers stay on their first ICE, Turbocharger, Exhaust, MGU‑Ok, and Power Retailer, suggesting that the brand new‑era energy items have launched with spectacular baseline robustness.

The primary indicators of divergence seem within the Management Electronics and associated ancillary methods, the place a number of drivers — together with George Russell, Kimi Antonelli, Lando Norris, Max Verstappen, Isack Hadjar, Carlos Sainz, Lance Stroll, Fernando Alonso, Esteban Ocon, Gabriel Bortoleto, and Valtteri Bottas — have already moved onto their second or third CE and PU-ANC unit.

Essentially the most notable outlier to date is Purple Bull’s Isack Hadjar, who has already used two ICEs, two Turbochargers, two Exhaust methods, and two MGU‑Ks. This degree of consumption so early within the season is uncommon and will level to a reliability concern, a precautionary change, or a thermal‑administration concern particular to his chassis.

Elsewhere, groups like Audi present remoted spikes in electrical element utilization. The general image is certainly one of sturdy reliability throughout the grid, however with early hints of the place the strain factors could emerge because the season progresses.
