FIA approves 2027 F1 engine changes
- The FIA said on May 8 that F1 teams, Formula 1 and the sport’s five power-unit makers agreed in principle on 2027 engine-rule changes. - The headline tweak is a roughly 50 kW shift from battery deployment to combustion power, plus higher fuel flow, after 2026 concerns surfaced. - It matters because 2026’s near-50/50 hybrid split is already being softened, with more changes possible before the final package is voted.
Formula 1’s next engine era was supposed to lean much harder on electric power. Now the sport is already backing away from the most aggressive part of that plan. On Friday, May 8, the FIA said teams, Formula 1 Management and the sport’s five power-unit manufacturers agreed in principle to reshape the 2027 rules by giving more power back to the combustion engine and taking some away from the electrical system. The point is simple — make the cars easier to race, safer, and less weirdly dependent on energy management. (fia.com) ### What actually changed? The proposed 2027 package would add about 50 kW to the internal-combustion engine, raise fuel flow, and cut ERS deployment power by about 50 kW. That is not final yet, but it is the clearest sign so far that F1 thinks the original balance for this rules cycle went too far toward electrical deployment. The FIA said more technical work still has to happen before the package goes to a formal vote. (fia.com) ### Why was F1 heading this way? The 2026 regulations were built around a much bigger hybrid contribution. When the FIA unveiled that ruleset in 2024, one of the selling points was an even split between combustion and electric power, plus almost 300% more battery power than the outgoing generation. That was part sustainability pitch, part manufacturer pitch — and it helped pull in a strong engine field for 2026. (fia.com) ### So what went wrong? Basically, the racing product started flashing warning lights early. The FIA has spent the first part of the 2026 season adjusting how the new cars harvest and deploy energy because drivers were having to manage the battery too aggressively. In April, stakeholders agreed changes aimed at re(fia.com) did not create fresh safety issues. (fia.com) ### What were those Miami fixes? They were mostly software-and-usage fixes, not a full hardware rethink. The FIA reduced maximum recharge from 8 MJ to 7 MJ, raised peak superclip power from 250 kW to 350 kW, and capped race-condition boost at +150 kW. It also kept 350 kW MGU-K deployment in key acceleration zones while limiting it to(fia.com)the racing. (fia.com) ### Why does 2027 need hardware changes too? Because software tweaks can only do so much if the core split is the problem. If a car depends too heavily on electrical deployment, drivers end up managing charge state instead of just attacking corners and exits naturally. The 2027 idea is to move the balance closer to combustion again —(fia.com)th every lap. Sky described the likely direction as closer to a 60/40 split. (skysports.com) ### Who has to sign off? The FIA has not formally approved a finished 2027 package yet. Friday’s step was agreement in principle after an online meeting with team principals, Formula 1 Management and representatives of the five power-unit manufacturers. Next comes more work in technical groups, then a manufacturer vote, then a World Motor Sport Council e-vote on the refined package. (fia.com) ### Why does this matter beyond one season? Because it tells you something bigger about F1’s new engine philosophy. The sport still wants hybrid relevance and sustainable fuel, but it is also admitting that the show matters and that drivers need cars they can race instinctively. That is a meaningful correction only months into the new era. (fia.com) ### Bottom line? This is F1 saying the 2026 concept was a little too ambitious in one specific place. The hybrid era is not being abandoned. But the sport is already trimming it back so the cars behave more like race cars and less like rolling energy spreadsheets. (fia.com)
