FIA Partially Restores Boost Mode for Remainder of 2026 Season

Formula 1 will partially reinstate Boost Mode for the remainder of the 2026 season after the FIA ratified safety-driven regulation changes. The updated rules allow the system to maintain power levels as cars slow on straights in wet conditions, but prohibit any additional output to address driver concerns over dangerous torque spikes.

Why it matters:

After drivers warned that the massive torque increase made the 2026 cars treacherous in slippery conditions, the FIA banned Boost Mode in wet weather earlier this year. The revised compromise prevents power from dropping off without adding extra performance, aiming to curb closing speeds in poor visibility while keeping the cars manageable.

The details:

• Boost Mode limits: In low-grip, low-visibility conditions, Boost Mode now operates solely to prevent power loss on straights. The overtake function remains completely disabled.
• Heat Hazard split: Organizers can now declare a Heat Hazard separately for the Sprint and main race, with 24 hours' notice. Drivers must then wear mandatory cooling vests or carry additional ballast.
• 2027 changes: The energy split shifts to 58 percent combustion and 42 percent electric in 2027, moving toward 60-40 by 2028. The FIA will limit reconnaissance laps at specific circuits and may shorten races by one or two laps.
• Testing extension: Pre-season testing for 2027 increases from three to four days to help teams manage regulatory complexity.

What's next:

The FIA describes these adjustments as part of an ongoing evolution of the 2026 regulations, with president Mohammed Ben Sulayem stressing that "continuous dialogue" is essential to balancing innovation, sustainability, and safety. As the sport heads toward further technical shifts in 2027 and 2028, expect further fine-tuning as teams and regulators adapt to the new era.
