Formula 1’s move to shorter Grand Prix races has cleared its next major hurdle, with the F1 Commission approving a reduction in standard race distance from 305km to 290km for 2027.
The change, agreed at the Formula 1 Commission meeting on 21 September, is tied to refinements to the 2027 power-unit regulations on fuel flow and is expected to cut most Grands Prix by around two or three laps.
It marks a significant step on from the proposal backed by Formula 1 teams earlier this month. At that stage, the 290km distance still needed to pass through the Commission. It now has — although the resulting regulatory changes remain subject to approval by the FIA World Motor Sport Council.
Why Formula 1 is cutting Grand Prix distance
The shorter race distance is not being introduced simply to make Grands Prix quicker.
Both the FIA’s official Formula 1 Commission statement and Formula 1’s own report describe the distance cut as being in line with refinements to the 2027 power-unit regulations on fuel flow.
Neither statement sets out a broader entertainment-led rationale for the change. The 290km distance is therefore best understood as part of the wider 2027 technical package rather than a standalone attempt to make races shorter for its own sake.
What has changed now is the proposal’s regulatory status: the F1 Commission has approved 290km as the new standard distance for 2027, pending the final WMSC step.
What 290km actually means for a Grand Prix
For fans, the practical difference should be noticeable without transforming the basic shape of a Formula 1 race.
The FIA says the reduction corresponds to around two or three laps at a typical circuit. Silverstone provides a useful example.
Formula 1 lists Silverstone at 5.891km, with the British Grand Prix currently running for 52 laps and an official distance of 306.198km. On the same layout, 50 complete laps would cover roughly 294.6km — two fewer than today.
The change is relatively small in terms of total race distance, but losing two or three laps can still affect tyre windows, fuel targets and the amount of time available for a late-race strategy to play out.
The sporting effect will vary from circuit to circuit. Shorter tracks may lose more laps numerically, while longer circuits could lose fewer, even though the overall distance reduction remains broadly similar.
Rain-hit races are changing too
The race-distance decision was not the only significant sporting change agreed by the Commission.
Formula 1 currently limits a Grand Prix to three hours from its start to its finish, including interruptions. From 2027, that three-hour overall limit is set to be removed and replaced by a hard-stop time for the end of racing activity.
The existing two-hour limit on actual racing will remain.
The intention is to give race control more flexibility when a Grand Prix is disrupted by heavy rain, lengthy barrier repairs or another major stoppage. Rather than the overall three-hour clock automatically closing down the available window, organisers will have greater scope to resume the race before the event reaches its fixed finishing point.
The FIA says the change is designed to give spectators the best possible chance of seeing a full race when interruptions occur.
Interrupted practice sessions get more flexibility
Free practice sessions are also set to become more flexible when they are interrupted.
The Commission agreed that there should be greater scope to extend a practice session following a stoppage. That could become particularly useful when a red flag removes a large part of the limited running available to teams.
With Sprint weekends already reducing the amount of conventional practice time — and the 2027 calendar expanding to 10 Sprint events — recovering lost track time can have a meaningful effect on preparation.
Gearbox homologation will disappear in 2027
Another technical change concerns Formula 1 gearboxes.
Following consultation with the relevant manufacturer working group and a recommendation from the Sporting Advisory Committee, the Commission agreed to remove gearbox homologation for 2027.
The FIA says the move is intended to preserve development freedom for suppliers. Minor changes to the 2027 Technical Regulations were also agreed, although the Commission statement does not go into further detail on those revisions.
The final approval step still matters
The F1 Commission has approved the changes, but they are not yet the final published regulations.
All regulatory changes agreed at the meeting remain subject to FIA World Motor Sport Council approval. That is the final formal step before the revised rules are incorporated into Formula 1’s regulations.
Once that approval is in place, 2027 Grands Prix will be shorter by distance while retaining the two-hour racing cap and adopting a more flexible approach to interrupted events. The distance change is modest in isolation; taken with the fuel-flow, practice and gearbox revisions, it shows how quickly Formula 1 is still refining the second season of its current technical era.
