Breakthrough Agreement on Upcoming F1 Regulatory Changes

FIA, Formula One Management, teams, and power unit manufacturers have agreed a regulatory package for 2027-2028, addressing energy management concerns from 2026. Approval is scheduled June 23 in Macau.

The update spans Technical, Sporting, and Financial Regulations. It rebalances combustion and electrical contributions, targeting faster qualifying, improved deployment headroom, and preservation of the current racing quality.

ICE peak increases from 400kW in 2026 to 420kW for 2027, then 450kW in 2028. Fuel flow rises 5% in 2027 and 13% in 2028.

MGU-K maximum output drops from 350kW in 2026 to 300kW for 2027 and 2028. Harvesting cap grows to 375kW in 2027 and 400kW in 2028.

The power split shifts toward combustion: 53% ICE in 2026, 58% in 2027, and 60% in 2028. That changes deployment strategies and reduces overreliance on battery energy.

The package responds to early-2026 feedback that cars were marginal on usable energy. The objective is robust race pace without undermining overtaking characteristics produced by the current aero restrictions.

Teams must revisit cooling, gearing, and energy calibration. Higher sustained combustion loads will influence reliability targets, fuel allocation, and lift‑and‑coast thresholds across power-sensitive venues.

With the MGU-K capped lower, deployment windows narrow, but stronger harvesting should offset losses over a lap. Expect greater variance by circuit layout and driver management style.

Fuel-flow increases should stabilise straightline attack phases and reduce late-lap vulnerability. That supports qualifying intensity and extends tactical flexibility during Safety Cars and undercuts.

The governing bodies will also adjust supply conditions, race operations, and cost controls for power units. These sit alongside the FIA engine overhaul deadline to maintain predictable development gates.

An accelerated approval pathway gives manufacturers build time for 2027 hardware. Homologation timing and dyno correlation become critical as teams phase upgrades through 2026.

Issues exposed at Montreal underscored the need for recalibration, as reflected in the 2026 Canadian Grand Prix results. The shift aims to curb extreme energy saving.
