F1 takes step closer to V8 return as fresh engine details emerge

The next set of F1 engine regulations is beginning to take shape after an agreement was reached between the sport's stakeholders.

RacingNews365 understands that as part of a major overhaul of the current units, F1 is heading toward a 3.0-litre turbocharged V8 engine with a simplified electrical system and a minimum 50kg weight reduction. 

A 2030 introduction is under consideration, which would cut the current technical cycle short by a year.

The new rules this season saw the influence of the battery increase, which caused criticism from many drivers who find the cars unenjoyable to drive.

It prompted FIA president Mohammed Ben Sulayem to outline his desire to bring back V8 engines as part of the next cycle, which were last used in 2013.

The idea was supported by many of F1's team principals, and it now seems it has taken a step closer to reality.

Turbocharged V8, but not naturally aspirated

One of the more contentious debates among manufacturers centred on whether to retain a turbocharger or go naturally aspirated.

While many fans and drivers would like to see a completely naturally aspirated engine, it seems the turbocharger is set to stay.

A key reason behind this is the realities of the modern calendar, with street circuits including Melbourne, Miami, Madrid, Singapore, Baku, and Las Vegas all operating under noise-emission restrictions. 

A smaller turbocharger offers a workable compromise, as the new engines are due to be notably louder than the current power units.

However, they would clear the hurdles in place relating to the decibels produced and keep in line with the city rules of some street tracks.

Decrease in electrical power and weight

Electrification is not being removed from the formula entirely. 

The next regulations are set to include a 100kW electric motor, a substantial step down from the 350kW electrical component that are part of the current generation of power units.

The intention is to preserve some link to the automotive industry and its electrification priorities, without recreating hybrid complexity that has made the current era expensive and challenging to understand.

While electric power will still feature, it is set to be in a far more supporting role than today.

Weight is the other headline target, after several years of driver complaints that the modern challengers are far too heavy.

The new power unit is being designed to come in at least 50kg lighter than current units.

Push-to-pass system

Several details have yet to be locked down, with one of them being the overtaking aid that will replace DRS, which was used through the end of the 2025 season. 

The current thinking draws on the push-to-pass philosophy seen in IndyCar, which functions as a driver-activated power boost available under defined conditions, rather than a mechanical drag-reduction device.

This remains one of the areas where the FIA and manufacturers have not yet reached a final agreement, and the specifics of how the system would work in practice are still being worked through.

The introduction date is similarly unresolved, with 2030 the figure under active discussion. 

Whether that timeline holds will depend on how quickly the remaining regulatory details can be settled.
