F1 bows to Verstappen, drivers criticism, agrees to massive 2027 engine shake-upAfter the constant criticism about the new regulations from Max Verstappen and others, the Formula 1 bosses have agreed in principle to make changes to the 2027 engine regulations. The plan is to slightly increase the output from the internal combustion engine following criticism from drivers earlier this season.F1 introduced major engine changes this year, featuring a 50-50 split between the traditional combustion engine and electrical battery power. However, several drivers raised concerns almost immediately over how heavily the cars relied on electrical deployment and energy harvesting. Verstappen openly slammed the new regulations, calling them fundamentally flawed. The FIA confirmed on Friday that discussions were held with teams and F1 officials during an online meeting, where the proposed tweaks were approved in principle."The measures agreed in principle today for 2027 would see a nominal increase in internal combustion engine (ICE) power by (tilde)50kW alongside a fuel-flow increase and a nominal reduction of the energy recovery system (ERS) deployment power by (tilde)50kW," the FIA statement said.The governing body also added that the adjustments would be "intuitive for drivers and teams."Earlier in the season, after only three grands prix, F1 had already introduced smaller tweaks to reduce the overall influence of electrical power. Those changes were aimed at improving the balance between driving skill and energy management, especially during qualifying sessions.Last weekend's Miami Grand Prix was the first race held under those updated rules. The race saw multiple lead changes between four different teams before Mercedes rookie Kimi Antonelli claimed his third win of the 2026 season.F1 has been running V6 hybrid engines since 2014, with electrical systems playing an increasingly significant role in race strategy over the years. Drivers now have to carefully manage battery deployment and recharging during races.The FIA said Friday's meeting also reviewed the impact of the changes introduced before Miami."The conclusion from the deployment of modifications in Miami, designed to improve safety and reduce excessive harvesting, was that they resulted in improved competition and were a step in the right direction," it said."Evaluation of the Miami package is ongoing with a view to the introduction of further adjustments at future events."The next race on the calendar is the Canadian Grand Prix on May 24.
