F1 agrees 2027 engine change

Formula 1’s next engine fight is already here — and the weird part is that it’s happening before the 2026 rules have even properly settled. On May 8, the FIA pulled together team bosses, Formula One Management, and the sport’s five power-unit manufacturers, and they agreed in principle to push through another round of changes. The immediate goal is to make the 2026 cars less awkward and less risky. But the bigger news is that everyone also opened the door to a more meaningful engine rethink for 2027. ### What exactly got agreed? Two things, basically. First, the group reviewed the tweaks already approved around the Miami Grand Prix for the 2026 package. Second, they backed a fresh set of “evolutionary changes” in principle, including a 2027 power-unit adjustment that would move away from the current planned balance between combustion and electrical power. It is not final yet — the FIA still says technical complications need more work. (fia.com) ### Why are they touching 2026 at all? Because the new rules started throwing up real-world problems as soon as teams and drivers got deeper into them. The 2026 formula is supposed to use fully sustainable fuel, drop the old MGU-H, and lean much harder on electrical deployment. On paper, that looked like a clean modern reset. But in practice, teams and drivers have been worried about drivability — especially how the cars deliver power over a lap — and about safety at circuits with long full-throttle sections. (fia.com) ### What is the 50/50 split people keep talking about? The 2026 engine concept was built around a much bigger electrical share than current F1 engines use. The shorthand version is a near-even split between internal-combustion power and battery power. That is the bit now under pressure. The proposal discussed for 2027 would shift the balance back toward the combustion engine — roughly 64% ICE and 36% electric — which is still hybrid, just less aggressively so. (formula1.com) ### Why would that help? Because a car that depends too heavily on battery deployment can run into ugly tradeoffs. If the battery harvest and release profile does not match the circuit, drivers can end up managing energy in ways that hurt racing and create odd speed differences. Think of it like a phone that charges fast but dies at the worst possible moment — the system looks great in a spec sheet, then becomes annoying in actual use. More combustion power gives teams a steadier baseline and reduces how much the whole lap hinges on electrical deployment. (fia.com) That is the basic logic here. ### Who had to sign off? Pretty much everyone who matters. The FIA says the meeting included team principals, Formula One Management, and representatives of the five power-unit manufacturers. That matters because 2026 already brought in a crowded supplier picture, with Ferrari, Mercedes, Honda, Audi, and Red Bull Ford Powertrains all tied into the next rules cycle. You do not start hinting at a 2027 redesign unless the manufacturers are at least willing to keep talking. (fia.com) ### So is the 2027 change locked in? No — and that is the catch. The language is “agreed in principle,” not signed, sealed, and published in final regulation form. The FIA is still flagging unresolved technical issues, which likely means the sport has not yet nailed down exactly how to rebalance performance without creating new cost, packaging, or homologation headaches. In F1 terms, this is a political green light, not the finished rulebook. (fia.com) ### Why does this matter beyond engine nerds? Because engines shape the racing. If the 2026 cars are too compromised, the whole championship risks spending its first year in damage-control mode. And if manufacturers think the formula misses the mark, the sport could end up stuck with expensive hardware nobody really loves. This move is F1 admitting early that the first draft may have leaned too far into battery dependence. (fia.com) ### Bottom line F1 has not scrapped the 2026 engine revolution. But it has started hedging against its biggest weakness. The sport still wants hybrid power and sustainable fuel — just with a little less theory, and a little more raceable reality. (fia.com)
