FIA writes return to 305 km race distance in 2028 into the 2027 rules
The published 2027 regulations contain a one-year dip in race length: grands prix shrink to 290 km in 2027, then return to the 305 km minimum from 2028. Monaco stays at 260 km. The shorter distance avoids bigger fuel tanks while power unit rules change.
A temporary cut with an end date
When the FIA announced shorter races for 2027, it was not clear whether the change would last. The newly published 2027 Formula 1 regulations now answer that: it is a one-year measure. According to RacingNews365 and GPFans, a section titled "Changes for 2028" restores the minimum race distance to 305 km from that season.
GPFans quotes the rule wording: the race length "shall be equal to the least number of complete laps which exceed a distance of 305km". RacingNews365 places the passage in Article B2.5.2.
Why races get shorter in 2027
The September decision followed an F1 Commission meeting. The FIA said at the time that the cut from 305 km to 290 km corresponds to two or three laps and is tied to refinements in fuel flow for 2027, as reported by Crash.net.
The logic is about packaging. The 2026 cars were designed around a particular balance between combustion and electric power. With the rules shifting towards more combustion power and a higher permitted fuel flow, cars would burn more fuel over a full distance. Rather than force teams to redesign chassis for larger tanks, the FIA shortened the race for one year. RacingNews365 describes the 2027 distance as a stopgap that buys time before the next power unit step in 2028.
The outlets give slightly different descriptions of the exact power-split percentages, so we do not repeat them here.
What stays the same
Monaco keeps its long-standing shorter minimum of 260 km in both seasons. Neither outlet reports an official FIA statement on the 2028 line itself; it appears in the regulation text.
What it means
For fans the practical effect is small in 2027: roughly two or three fewer laps at a typical circuit. The 2028 line matters more for engineers, because it signals that teams must find a way to carry enough fuel for the full distance again, with chassis and tank design questions that are still open.
Our data shows how much racing is still ahead this year: 17 of the 23 races in 2026 have been run, and the next one is the United States Grand Prix in Austin on 25 October. The 2027 rules, including the shorter distance, take effect only after this season ends.
