F1's planned shift to a 60:40 internal combustion to electrical power distribution in 2027 could severely impact teams and potentially "punish" Mercedes, according to analyst Naomi Schiff. The FIA aims for "more intuitive" driving by decreasing electric power by 50kW and increasing ICE power by the same amount. Schiff suggests this could disrupt Mercedes' current engine dominance, potentially denying them an "era of domination."
The technical ramifications are significant. While the new battery split promises more efficient energy use and less driver management, it also requires burning more fuel. For many teams, this increased fuel demand could necessitate entirely new fuel cells, triggering drastic chassis redesigns. Teams already well into their 2025 and 2026 car designs, with wind tunnel deadlines approaching, might have to scrap progress and return to the drawing board. This mid-development rule change forces a major reset, potentially leveling the playing field but creating significant upheaval and cost for all constructors ahead of the new regulations.
