Formula 1 and power unit manufacturers have agreed on the main parameters for the next generation of engines. The preliminary configuration is a 3.0-liter turbocharged V8 with a simplified hybrid system and the goal of reducing the power unit's mass by at least 50 kg. However, the final rules and launch date have not yet been approved.
The main change will concern the electrical part. The electric motor's power is planned to be reduced from the current 350 to 100 kW. Thus, the main role will again shift to the internal combustion engine, but hybrid technology will not completely disappear.
Noise was one of the reasons why engineers abandoned the naturally aspirated V8. Such an engine would be too loud for the current restrictions on the tracks in Melbourne, Miami, Madrid, Singapore, Baku, and Las Vegas. A small turbine will allow for a more expressive V8 sound while meeting the established norms.
For comparison, the Formula 1 power unit, active since 2026, retains a 1.6-liter V6 and a significantly larger share of electric power. The FIA has already confirmed that the adjustment of the ICE and ERS ratio is ongoing in the current cycle.
The new 3.0-liter V8 will be the largest displacement Formula 1 engine since the 3.0-liter V10s used until 2005. However, this is currently only an agreed concept: the final configuration may still change.
