Shorter F1 Races Planned
Formula 1 plans to shorten 2027 races to adapt to new power-unit fuel requirements.

Key Points
1
The revised power-unit balance is expected to shift to approximately 58% internal-combustion power and 42% electric power in 2027, before moving to a 60-40 split in 2028.
2
The 2027 power-unit adjustments followed criticism of the initial 2026 regulations, with teams and stakeholders seeking to reduce “superclipping” and recharging so drivers could spend more of each lap at full throttle.
3
Keeping the existing fuel-tank size while maintaining the original race distance could have forced teams to make hardware changes and use cost-cap funds on larger tanks; shortening races avoids that expense.
4
The FIA World Motor Sport Council is scheduled to consider the proposals at a virtual meeting on October 15, when the race-distance and related regulation changes are expected to receive final approval.
5
The three-hour race window replaced an earlier four-hour limit in 2021, so the 2027 change would reverse a restriction introduced after that previous format was shortened.
Formula 1 will shorten most 2027 Grand Prix races by 15 kilometers, cutting the standard distance from 305km to 290km, according to Freedom 96.9. The change means most races will be two or three laps shorter. Monaco's 260-kilometer race will stay the same.
The decision stems from new power-unit rules. In 2027, engines will shift toward more internal-combustion power and less electric power. This requires more fuel to complete the old distance. Rather than force teams to buy bigger fuel tanks, F1 is shortening races to keep fuel use manageable under the existing tank size.
Power-Unit Changes Drive the Need for Shorter Races
F1's 2027 power units will run at a different balance than today. Internal-combustion engines will provide roughly 58% of power, while electric motors supply 42%, according to Speedcafe. This shift away from hybrid power means cars need more fuel to run the full 305-kilometer distance.
Fuel-tank capacity will not grow. Keeping races at 305km would have forced teams to install larger tanks, eating into their spending budgets. Shortening races to 290km solves this problem without expensive hardware changes or budget hits.
The 2027 Shift Fixes Complaints About Earlier 2026 Plans
F1 originally planned even more electric power in 2026. Teams complained that too much 'superclipping'—artificial power limits—and frequent recharging kept drivers off full throttle. The sport redesigned the rules to favor traditional engine power instead.
The 2027 power split of 58-42 is a bridge to 2028, when engines move to a 60-40 internal-combustion-to-electric ratio. This gives teams and suppliers time to adapt to the new direction without radical mid-season changes.
Other Rule Changes Drop Three-Hour Race Window
F1 will also remove the three-hour overall time limit for races interrupted by rain or red flags, Speedcafe reported. A two-hour limit on actual racing time will remain in place. The change reverses a 2021 decision that shortened the window from four hours.
Teams can now extend disrupted practice sessions with greater flexibility. Gearbox rules will also change: 2027 gearboxes will not be locked into a single design, letting suppliers develop freely. The FIA World Motor Sport Council is set to vote on all changes on October 15.
