Formula 1 has announced the maximum race distance for grands prix will be reduced by 15km from 305km (189.5 miles) to 290km (180.2 miles) for the 2027 season.

Grands prix are limited to a maximum of two hours of racing, but when there are interruptions caused by rain or accidents, a "hard stop time" will replace the current maximum three-hour duration to finish the event. This will allow for greater flexibility to complete disrupted races. A statement from governing body the FIA said: "These changes were introduced to ensure that the spectators have the best possible chance to enjoy a full race if disruptions occur."

The hard stop time will vary from race to race, depending on local conditions. At night races, for example, there will be more flexibility to allow the race to run later than at a daytime race when there is a relatively early sunset.

The reduction in race distance has been introduced because the ratio of internal combustion to electrical power is changing from 53-47 this year to 58-42 next year, before becoming 60-40 in 2028.
