Formula 1 Tweaks Engine Rules After Driver Complaints Over New Power Units

Formula 1 has introduced a fresh set of rule adjustments to deal with concerns surrounding the new engine regulations brought in this season.

The latest power units, which split output almost evenly between combustion and electric energy, have drawn criticism from drivers who feel the heavy focus on energy management reduces the importance of driving skill. Four-time world champion Max Verstappen has even suggested he may rethink his future in the sport due to frustration with the new system.

The updated rules focus on refining how engines are used, with the aim of allowing drivers to push harder during qualifying and limiting major speed gaps in races. Previously, there could be a difference of up to 470bhp between cars running full power and those with depleted battery energy.

Most of the changes are expected to take effect at the upcoming Miami Grand Prix scheduled for 1–3 May.

Mercedes team principal Toto Wolff described the approach as making careful, precise improvements rather than drastic changes.

“We all want the same thing – to improve racing, make it more competitive, and ensure safety,” Wolff said.

The revisions were agreed during a meeting involving F1 teams, the sport’s organisers, and the governing body FIA. Final approval is still required from the FIA World Council.

In qualifying, the new rules are designed to cut down on excessive energy saving and encourage drivers to maintain full speed more consistently. Previously, drivers often had to lift off the throttle early before corners to conserve energy – a method many described as unnatural.

The maximum energy recovery per lap has been reduced from 8MJ to 7MJ, lowering the need for energy harvesting. At the same time, the limit for energy recovery while at full throttle – known as “super-clipping” – has been increased from 250kW to 350kW.

According to the FIA, this should limit super-clipping to just two to four seconds per qualifying lap.

Additionally, the number of tracks where even lower energy limits may apply has been increased from eight to 12. These are usually circuits with long straights and fewer corners, where energy recovery is more difficult.
