The 2026 Formula 1 engine regulations are set to introduce a driver-operated KERS-style ‘override’ boost system to its energy deployment power unit map.
It was previously announced that the turbocharged 1.6-litre V6 internal combustion engine element of the power unit will be reduced from 550-560kW to 400kW, while the battery element will increase from 150kW to 350kW.
Despite the removal of the MGU-H, the more powerful hybrid system aims to enhance wheel-to-wheel racing.
The latest draft of the 2026 power unit regulations, unveiled by the FIA, includes plans for a KERS-style boost system, outlined in Article 5.4.8, where drivers can reach top speeds of 345km/h under standard use and use the ‘override’ mode to deploy additional battery power, enabling a boost up to 355km/h.
Similar to the KERS function used from 2009-2013, drivers must strategically decide when to use this energy, as it may result in an energy deficit under normal deployment conditions.
With these changes emphasizing the move to increased electrification, Audi and Ford have joined the four existing engine manufacturers on the 2026 grid.
New chassis rules are also set to make cars lighter, F1 has revealed, and the addition of an extra moveable aero will increase aerodynamic efficiency and reduce drag on straights.
