F1 Commission approves shorter races for 2027 power unit era

The F1 Commission has rubber-stamped a 15km reduction in grand prix race length for 2027, aligning the sport with its next-generation power unit rules. The standard race distance will drop from 305km to 290km, pending approval from the FIA's World Motor Sport Council.

Why it matters:

The change is driven by the 2027 powertrain recalibration, which increases internal combustion engine output while reducing electrical power. Rather than enlarging fuel tanks to accommodate the new fuel flow rate, the sport has chosen to shorten races, minimizing the risk of drivers running out of fuel. This will cut roughly three laps from most circuits, subtly altering strategy and race dynamics.

The details:

• Power unit shift: The ICE output rises to 420kW, while the MGU-K maximum drops to 300kW (350kW in overtake mode). Fuel flow increases by five percent to support the higher combustion output.
• Race distance: Reduced from 305km to 290km for 2027 only. In 2028, further changes—450kW ICE power and a 13% fuel flow increase—will require a larger tank, so the shortened length may be temporary.
• Red flag timing: The three-hour maximum race window is removed, replaced by a hard stop time to account for daylight. The two-hour racing limit remains unchanged.
• Practice flexibility: Race directors can now extend free practice sessions after extended red flag periods, a response to incidents like the truncated FP3 at the Spanish Grand Prix.
• Gearbox development: Homologation is rescinded for 2027, allowing manufacturers to continue transmission development next season.

What's next:

The proposals now head to the WMSC for final ratification. If approved, teams will begin adapting chassis and cooling designs to the shorter-race format, while the 2028 regulations promise another significant reset for the sport's power unit landscape.
