Formula 1 grands prix will be shortened from the traditional 305km to 290km starting in 2027, as the series adapts its technical regulations to a new balance between electrical and internal-combustion power.
The move, which is set to be ratified by the World Motorsport Council, is a response to widespread criticism of the current power unit rules. The equal 50:50 contribution from electric and combustion engines has led to unpopular driving styles and “yo-yo” racing, as drivers constantly manage battery levels and energy deployment.
From 2027, F1 will adjust the ratio to 58:42 in favor of internal combustion, before shifting further to 60:40 in 2028. Increased fuel flow will be allowed, but rather than enlarge fuel tanks—adding unwanted weight—F1 has opted to shorten race distances across the board. Monaco’s unique layout will see its race trimmed from 260km as well.
The decision to standardize all races at 290km is designed to avoid spotlighting specific “fuel-critical” tracks and minimize ongoing criticism of the new regulations. Teams, who initially planned to carry over their 2026 chassis and fuel tank sizes, have since embraced new aero rules, making shorter races the most practical solution.
The change signals F1’s ongoing struggle to balance sustainability, performance, and the spectacle of racing as the sport enters a new technical era.
