McLaren team principal Andrea Stella has issued an urgent call for Formula 1 to implement critical safety refinements to its revolutionary 2026 power unit regulations before the Australian Grand Prix on March 8. The plea comes after Bahrain's preseason test exposed three significant operational and safety concerns that threaten both driver welfare and competitive racing.
The 2026 power units represent a seismic shift for the sport, with electric components now accounting for nearly 50% of total power output. While innovation drives F1 forward, the technical complexities unveiled during testing have prompted Stella to demand urgent intervention at next week's F1 Commission meeting—a gathering with all 11 teams, the FIA, and Formula 1 officials.
The most immediately dangerous issue concerns grid procedures and power unit preparation. With the removal of the MGU-H hybrid system, cars now rely entirely on the V6 turbo engine for initial acceleration, requiring drivers to rev aggressively for over 10 seconds to build sufficient turbo boost pressure and eliminate turbo-lag.
During Bahrain testing, the timing window proved perilously tight, with drivers at the rear of the grid potentially unable to complete the necessary spool-up before the lights extinguish. Alpine's Franco Colapinto experienced an anti-stall failure on Friday, highlighting the mechanical fragility of the current system. Stella emphasized the gravity of the situation: "There are some topics which are simply bigger than the competitive interest. And for me, having safety on the grid, which can be achieved with simple adjustment, is just a no-brainer."
The second concern involves the dangerous practice of "lift and coast"—where drivers lift off the throttle to recharge battery capacity. Following cars unaware of sudden deceleration could face catastrophic consequences. Stella referenced historical airborne incidents, specifically Mark Webber's 2010 Valencia shunt and Riccardo Patrese's 1992 Estoril crash, as cautionary tales the sport cannot afford to repeat.
Energy conservation is so critical under 2026 regulations that circuit complexity directly impacts this risk. Barcelona and Bahrain—relatively straightforward layouts—are not even considered worst-case scenarios; power-hungry circuits could escalate incidents further.
Finally, the elimination of DRS and introduction of active aerodynamics has created an overtaking crisis. While all cars can now flatten their wings on designated straights, this removes any competitive advantage for the pursuing driver.
McLaren drivers found it "extremely difficult to overtake" during Bahrain testing, according to Stella. The replacement boost mode delivers insufficient speed differential to compensate, as cars lack sufficient remaining battery energy to deploy meaningful power. One proposed solution involves reducing maximum allowed electric power output from 350kW—potentially allowing superior energy deployment and more effective overtaking opportunities.
Stella's message is unequivocal: "These simple technical solutions exist and they will be discussed in the next F1 Commission". With safety grounds potentially allowing the FIA to implement changes unilaterally, the regulatory body faces mounting pressure to act decisively. Formula 1's credibility depends on addressing these concerns before drivers take to Albert Park.
