F1 changes maximum race distance to 290km from 305km for 2027

Formula 1 announced on September 21, 2026, that it will reduce the maximum race distance for grands prix from 305 kilometers to 290 kilometers starting in the 2027 season. This change aims to allow greater flexibility during races disrupted by rain or incidents, replacing the three-hour finish time with a variable 'hard stop time' depending on local conditions. The modification follows an increase in the ratio of electrical power used by cars, leading to concerns over fuel consumption and race completion. Additional changes include extending free practice sessions if interrupted by red flags. The new rules reflect ongoing efforts to improve the racing experience for spectators.
