FIA amends Formula E Sporting Regulations for Gen4: New Attack Mode, tyre, energy & penalty rules

The FIA has once again amended the Sporting Regulations for the 2026/27 Formula E season. Shortly before the start of the first Gen4 season, the rules concerning Attack Mode, energy consumption, tyres, component allocations and penalties, among other areas, have been changed. e-Formula.news has compared the new version with the regulations most recently published in June.

The Formula E Sporting Regulations have now been published entirely in English by the FIA. Previously, the regulations had always been bilingual, with a French version included as well.

Article 2: Championship Competitions

Performance races will now be referred to as "E-Prix Unleashed", while efficiency races will be known as "E-Prix".

If the scheduled distance, including the number of added laps, is not completed in time, the "E-Prix Unleashed" will now be subject to a 60-minute time limit instead of 45 minutes. There are no changes for the "E-Prix". In the event of a suspension, the maximum total duration of an "E-Prix Unleashed" may now be extended to 90 minutes plus one lap instead of 75 minutes plus one lap.

Article 3: Formula E World Championship

At the annual FIA prize-giving ceremony, a representative of the winning manufacturer must now also be present, in addition to the top three drivers and the Team Principal of the winning team in the Teams' Championship.

Article 9: Incidents

It has been clarified that, in addition to exceeding the permitted power level, excessive energy consumption may also be treated as an incident and investigated by the stewards.

As an additional option, the stewards may now also drop a driver by any number of positions in the race classification.

Article 12: Testing

During official tests, essentially the same tyre regulations as at race events now apply. Exemptions concern the number of available tyre sets as well as the rules for joker tyres and replacement tyres.

Article 13: Pit Lane

It has been clarified that electric wheel guns are mandatory only for tyre changes. Tyre changes are permitted in every session and must be carried out either inside the garage or in the section of the pit lane allocated to the respective team for pit stops.

The maximum permitted power in the pit lane is 450 kW. The 600 kW four-wheel-drive mode is explicitly prohibited there.

Article 14: Scrutineering and Administrative Checks

It has been clarified that the driver's licence submitted by the team must be at least an International Grade B licence. Previously, the regulations referred only to a Grade B licence, which in theory could also have meant a national licence.

Article 15: Use of Tyres and Tyre Limitations During the Competition

The previously defined penalty framework for using tyres without the required RFID or barcode identification has been removed. Instead of a grid penalty or disqualification, such an infringement will now be reported to the stewards.

In addition to tyre pressures, tyre temperatures will now also be monitored at all times.

The use of joker tyres must now be approved not only by the stewards, but also by the Technical Delegate.

It has been clarified that any form of physical connection to the tyres is prohibited during the tyre parc ferme. Outside parc ferme, teams may work on the tyres in the pit lane in front of their garages. The tyre parc ferme now opens 30 minutes instead of 45 minutes before the first session of each event day, allowing teams to adjust tyre pressures.

Ten minutes before a Free Practice session, Qualifying, or the opening of the pit lane before the race, teams may now remove a maximum of two tyre sets per car from the designated tyre storage area, the so-called Tyre Area. One of these sets must be fitted to the car, while the second set must remain stacked and clearly visible in the middle of the garage or on the dummy grid. Once the chequered flag has fallen, the tyre set not fitted to the car must be returned immediately.

The Tyre Area is defined by the FIA and may not be altered by teams without FIA approval. Spacers between tyres may only be used if they are supplied by the tyre supplier. Tyres may be placed on wheeled platforms or grid trolleys, but only for storage or transportation. Any means of retaining or increasing tyre temperature is prohibited.

Teams are responsible for ensuring that the tyre monitoring systems are fully operational from the start of the first tyre parc ferme of the event.

Article 17: General Requirements for Cars and Personnel

Each team may appoint a maximum of two non-operational personnel who may carry out exclusively non-operational tasks in the garage. The FIA Sporting Delegate has the right to reject individuals proposed for this role.

Instead of one week before an event, teams must now submit their personnel lists no later than the Friday of the week before the event.

The regulations concerning the emergency braking system have been removed from the Sporting Regulations, as the Gen4 cars do not feature such a system.

Article 18: Spare Cars, Motors, Batteries and Gearboxes

The rules concerning the front powertrain have been tightened considerably. Each car may, in principle, use only one Front Powertrain Kit (FPK) for the entire season. At the same time, the two additional FPKs per team that had previously been included in the pool of so-called Floating Parts have been removed.

Instead of four sets of brake discs at both the front and rear, each driver will now have three rear sets and five front sets available. Brake pad sets are no longer limited separately per axle, with eight sets each, but instead by an overall total: 16 sets may be used by a driver over the course of the season.

Article 23: Qualifying

The previously defined maximum of four mechanics permitted to work on the car during a tyre change has been removed.

For all laps in the Duel phase, the maximum power level is now set at 600 kW.

Article 26: Start Procedure

Once the Race Director has issued the "Standing Start" message following a start behind the Safety Car, burnouts are now strictly prohibited.

Article 27: The Race

The FIA will set the Race Mode power three weeks before an event, with a maximum of 450 kW. For individual races, the FIA may also introduce a so-called Power Schedule, defining the maximum available power depending on vehicle speed. In Attack Mode, a fixed 600 kW will no longer be available; instead, the maximum power will increase by 150 kW compared with Race Mode.

The activation area for Attack Mode is now officially called the Attack Zone.

If the race is neutralised by a Safety Car, Full Course Yellow or red flag, the driver may freeze the remaining duration of their Attack Mode. The remaining Attack Mode time resumes the next time the driver passes through the Attack Zone. This does not count as one of the required Attack Mode activations.

Once a car has entered the pit lane, it is no longer possible to change the amount of energy to be added during Pit Boost. In the previous draft of the regulations, this remained possible until the charger was connected.

For certain races, the FIA may now define a Minimum Energy Consumption per lap. If a driver consumes less energy than this value on a lap, the defined minimum will nevertheless be deducted from the available race energy. The rule does not apply in the event of an incomplete opening lap, the so-called lap zero, after a standing start, on the final lap of a race, under Full Course Yellow or Safety Car, once the track has been declared wet, when driving through the pit lane, or during a race suspension.

Article 30: Suspending a Race

The duplicate provision stating that a car undergoing repairs must be placed at the back of the restart order has been removed in one of its two locations.

Article 31: Resuming a Race

As in Article 26, burnouts are now strictly prohibited at a restart once the Race Director has issued the "Standing Start" message.

Appendix 3: Team Branding Manual

For the first time, the Sporting Regulations include a detailed Team Branding Manual for Gen4. It defines fixed areas for ABB, Bridgestone, various FIA and Formula E logos, as well as the manufacturer logo. Driver number, three-letter abbreviation, driver name and national flag are also assigned precisely defined positions.

A minimum clearance of 20 mm on all sides is also required for all logos. The ABB logo must be either red or white, while the Bridgestone logo must be either red and black or white.

Race numbers must be displayed on the nose of the car, on both sides of the rear wing, and on the left-hand side of the Halo in the direction of travel, where they must also be combined with the driver's three-letter abbreviation. Race numbers must be either black or white. The fonts are also prescribed.

The driver's flag and name must be displayed next to the cockpit. Teams may choose between black, white and the team colour.
