F1's 2026 relaunch: rule changes & engine upgrades unlocked

The latest episode of the Motor Sport F1 Show with Mark Hughes dives into the imminent rule changes set for the 2026 F1 season, particularly focusing on the upcoming adjustments to the energy split between the internal combustion engine (ICE) and electric systems ahead of the Miami Grand Prix. Mark explains that while there is broad consensus among teams to implement changes, the specifics—especially around deployment rates, battery storage, and potential ICE power increases—remain under discussion. Red Bull is pushing for more ICE power, while Mercedes appears content with the status quo, though its true performance remains opaque. The episode also explores the controversial 'additional development upgrade' system, which allows teams behind by 2% to 6% to receive incremental upgrades and dyno time, with the FIA maintaining sole authority over measurements. A major highlight is the announcement that Max Verstappen’s long-time race engineer, Gian Piero Lambiasi, is moving to McLaren in 2028, a career move driven by Lambiasi’s ambition beyond being tied to a single driver. Mark analyzes the implications of this departure, noting it's not tied to Verstappen’s future plans but reflects broader team restructuring at Red Bull. The episode concludes with audience questions on qualifying tactics, closing speeds between cars, and the potential for standardized engine maps—concluding that mechanical differences make standardization impractical, and a more graduated deployment system would be a better solution. Despite the complexity, the show ends on a note of cautious optimism that Miami may finally bring some clarity to the season’s turbulence.
