F1 2026 overhaul: bigger power, active aero and energy caps

Formula 1 will enter a markedly different era in 2026, with sweeping engine, aerodynamic and chassis rule changes that shift the sport toward heavier reliance on electric deployment, introduce active aerodynamics in place of DRS and impose circuit‑specific energy limits aimed at reining in top speeds. The changes, announced by the governing body and discussed with teams this year, will take effect across the championship next season and apply at every venue, with Monaco singled out for special caps to prevent excessive speed in the tunnel.

At the heart of the overhaul is a major rebalancing of the power unit. The controversial MGUH element will be removed, while the MGUK output will rise substantially, from roughly 120 kilowatts today to about 350 kilowatts, creating a roughly threefold increase in electrical power available from batteries. Internal combustion engines will remain but will run on fully sustainable fuels, and overall packages are expected to peak at more than 1,000 horsepower. The FIA has also developed detailed, confidential energy management charts that impose different charge and discharge limits by circuit and by session, according to officials familiar with...
