F1 2026: Teams Test Reduced Power Deployments Amidst New Engine Concerns

Formula 1 teams are evaluating a potential workaround for challenges related to the new 2026 power units, focusing on battery charging and consistent power delivery during qualifying laps. Testing in Bahrain included running with reduced electric power deployment to assess its impact on energy management and overall performance.

Concerns with the New Power Units

The primary concerns center around the techniques required to efficiently charge the battery and ensure full power deployment throughout a qualifying lap. Teams have been employing aggressive downshifts and a technique called ‘super clipping’ – temporarily halting electric power deployment although maintaining full throttle to charge the battery – alongside traditional recharging methods like braking and lifting and coasting. Motorsport.com reports that optimization has improved significantly during testing, but drivers have noted compromises needed to maximize charging and deployment.

Exploring Potential Solutions

Several solutions are being considered, including reducing peak MGU-K power output. The FIA has invited teams to test with reduced MGU-K power to understand how it affects recharging requirements. The question is whether running with lower peak power would allow for more frequent power usage. This is a long-considered backup plan, with potential reductions ranging from 350kW to 300kW, or even as low as 200kW.

Other proposals include allowing teams to utilize more fuel to increase internal combustion engine power, or increasing battery recovery during ‘super clipping.’ McLaren has suggested allowing the MGU-K to operate at full capacity in reverse (350kW) to eliminate the necessitate for lifting and coasting. Teams have been testing super clipping at 350kW.

Prudent Approach and Future Outlook

Stakeholders generally agree on a cautious approach, preferring to gather data from several races before implementing regulatory changes. The season begins in Australia, a track with limited recharging opportunities, and continues with challenging circuits like Suzuka and Jeddah. Sky Sports highlights the importance of identifying “lightest-touch fixes” early in the season.

Grand Prix Drivers’ Association director Carlos Sainz has urged Formula One Management (FOM) and the FIA to remain flexible and open to adjusting regulations if the current energy management requirements prove overly restrictive. Senior figures within F1 express optimism that the progress made with the new engines suggests these are short-term issues.

Teams have demonstrated significant improvements in energy deployment tactics since the initial Barcelona test, gaining several tenths of a second in lap time. This progress suggests that wholesale changes may not be necessary, even if refinements are required.
