Formula 1 to Reduce Maximum Race Distance by 15km from 2027

Formula 1 has announced a reduction in the maximum race distance for Grands Prix, lowering it by 15 kilometers from 305km (189.5 miles) to 290km (180.2 miles) starting in the 2027 season.

In addition to the distance reduction, a "hard stop time" will replace the current maximum three-hour duration for completing a race, especially when interruptions occur due to incidents or weather. This change aims to provide greater flexibility in completing disrupted races.

A statement from the FIA, the sport's governing body, indicated that these adjustments are intended "to ensure that the spectators have the best possible chance to enjoy a full race if disruptions occur." The specific hard stop time will vary for each race, influenced by local conditions such as daylight hours for daytime races or allowing later finishes for night races.

The decision to shorten the race distance is linked to evolving engine regulations. The ratio of internal combustion power to electrical power is shifting from 53-47% this year to 58-42% in 2025, and further to 60-40% by 2028. This change means cars will consume more fuel. Concerns arose that some teams might wish to carry over chassis from one year to the next to reduce costs. As the fuel tank is integrated into the chassis and its size cannot be altered, these teams might have faced challenges completing races with their existing fuel capacity under the previous distance regulations.

Further modifications agreed upon by the F1 Commission, which includes representatives from the teams, the FIA, and the commercial rights holder, will allow for increased flexibility in extending free practice sessions if they are interrupted. Current regulations do not halt the clock during practice sessions when a red flag is deployed due to an incident, unlike in qualifying and races where competition is suspended.
