From 2027 the minimum race distance for an F1 grand prix drops from 305km to 290km. The third F1 Commission meeting of the year, held at the FIA's London offices on Monday 21 September, approved the plan, which will make races two to three laps shorter depending on the circuit. The reason is not spectator convenience but the power unit. Revisions to the 2027 fuel-flow rules mean more fuel is needed, and rather than enlarging fuel tanks, the choice was to cut distance.
Why 15km: the combustion engine does more of the work
The official explanation from the FIA and F1.com is brief: the adjustment is linked to the revision of power unit fuel-flow regulations coming in 2027. The Race and Grandprix.com fill in the background. The plan is to shift the split between combustion and electric power further towards the combustion engine, to 58:42 in 2027 and 60:40 in 2028. Outlets describe the current split slightly differently: The Race puts it at around 53:47, while Motorsport.com and Grandprix.com say 50:50. Either way, for the combustion engine to do more work, fuel flow has to rise, and that means more fuel on board for each race.
More fuel needs bigger tanks. But many teams plan to carry their 2026 chassis over into 2027, and modifying them for larger tanks would be costly under the cost cap. Grandprix.com called the approach "the least disruptive way" of giving the engines more fuel flow without adding weight to the cars. There was also an option to shorten only the fuel-critical circuits, but according to Motorsport.com it was applied across every event to avoid a recurring annual debate about particular races being shortened.
How many laps each circuit loses
The official statement says only "two to three laps" and gives no circuit examples. Taking the Baku City Circuit, which hosts Saturday's race, gives a feel for it. According to F1 Live Pulse, a lap of Baku is 6.003km and this year's race is 51 laps, 306.049km. If the rule keeps its current form of "the fewest complete laps exceeding the minimum distance", 49 laps would be enough to pass 290km, two fewer. That calculation is ours, not a confirmed FIA figure. Motorsport.com lists the current lap counts as 44 at Spa-Francorchamps, 51 in Baku and 78 in Monaco.
Monaco, with its low average speed, already uses a separate 260km standard. The sources disagree on the future of that exception. The Race wrote that Monaco stays at 260km, while Motorsport.com and Grandprix.com wrote that Monaco could be adjusted under the same framework. That will only be settled once the World Motor Sport Council (WMSC) text is published in October.
| Year | Race distance rule |
|---|---|
| 1950 | Up to the organiser. Anything from 325km at Silverstone to over 500km at Monza |
| 1958 | Distance ceiling reduced, two-hour maximum introduced |
| 1971 | Cut to a maximum of around 322km |
| 1989 | Standardised at a minimum of 305km (to finish within two hours). Kept until 2026 |
| 2027 | Minimum 290km. Two to three fewer laps per circuit |
The table follows Motorsport.com's summary.
Other decisions from the meeting and the remaining steps
The same meeting also approved scrapping the three-hour total limit on suspended races in favour of a hard-stop time, and scrapping gearbox homologation for 2027. All of the decisions need FIA World Motor Sport Council approval, which The Race says is due on 15 October. Motorsport.com added that drivers' complaints this year about "yo-yo" driving, with speeds rising and falling because of battery charging and deployment, are also behind the move to give the combustion engine a bigger share.
