- Formula 1 could introduce 2.0 to 2.3-litre V8 turbo hybrid engines from 2030 or 2031, with the FIA proposing a major overhaul to address criticism of the current power unit regulations.
- The proposed regulations would reduce electrical output from 350kW to 200kW, target an 80kg weight reduction and retain sustainable fuels while placing greater emphasis on internal combustion engine performance.
- While manufacturers reportedly support the return of V8 engines, disagreements over standardisation, development costs and a proposed reduction in the power unit budget cap remain unresolved ahead of further FIA discussions.
Formula 1 could return to V8 turbo hybrid engines from 2030 or 2031, with the FIA outlining an ambitious proposal to simplify power units and address the shortcomings of the sport’s controversial 2026 regulations.
According to BBC Sport, a proposal document circulated amongst Formula 1’s six engine manufacturers details plans for cheaper, lighter and more powerful internal combustion engines, while significantly reducing the reliance on electrical energy.
The proposed regulations would see the current 1.6-litre V6 turbo hybrids replaced by 2.0 to 2.3-litre V8 engines, featuring smaller turbochargers and a considerably less powerful electrical system.
A significant departure from the current regulations, which have drawn widespread criticism from drivers over energy management requirements and the impact upon traditional racing characteristics.
Four-time world champion Max Verstappen previously likened the new generation of machinery to “Formula E on steroids”, while Fernando Alonso described the championship as the “battery world championship”.
Indeed, the requirement to harvest electrical energy has seen drivers compromise their approach through traditionally demanding corners, with Alonso describing high-speed sections as little more than “the charging station for the car”.
Reduced electrical reliance and lighter machinery
Under the proposed framework, electrical energy recovery would be reduced from the current 350kW to 200kW, with half of that capacity available continuously and the remainder reserved for an overtaking function.
The internal combustion engine would consequently provide the majority of the approximately 900bhp total output, restoring greater emphasis on conventional engine performance.
Meanwhile, the FIA is targeting an overall weight reduction of 80kg, alongside the continued use of fully sustainable fuels.
Such changes would represent a substantial philosophical shift from the current regulations, which have prioritised electrical deployment at the expense of outright performance through certain sections of the circuit.
The proposal also signals a retreat from FIA president Mohammed Ben Sulayem’s previous ambitions to reintroduce naturally aspirated engines, having initially advocated for a return to V10 machinery.
Retaining turbocharging and hybrid technology instead offers a compromise between the demands of manufacturers and those seeking a more traditional Formula 1 spectacle.
Manufacturers resist standardisation
While the fundamental V8 architecture has reportedly received broad support, several aspects remain contentious.
Amongst the proposals is the possibility of introducing a standardised engine platform supplied by an external manufacturer, although existing power unit suppliers are understood to favour retaining their own development programmes.
An alternative would allow manufacturers to adapt their existing V6 designs into V8 configurations, potentially reducing the engineering costs associated with another wholesale regulatory overhaul.
The FIA has also proposed halving the annual power unit budget cap from its current $190 million, though the financial implications and potential workforce reductions remain subjects for negotiation.
With Mercedes, Ferrari, Honda, Audi, Red Bull and prospective manufacturer Cadillac involved in discussions, securing consensus will be crucial.
The timing of the regulations also remains unresolved, particularly given existing commercial agreements run until 2030.
For Formula 1, the proposals represent an acknowledgement that the sport’s latest regulatory overhaul has not delivered the intended balance between technological innovation and the demands of racing.
And while the introduction of V8 engines remains several years away, the prospect of lighter machinery, reduced energy management and a more visceral soundtrack will undoubtedly appeal to those disillusioned with the current formula.
The challenge now is translating those ambitions into regulations that satisfy manufacturers without compromising the spectacle which has long defined Formula 1.
Discussions are expected to continue ahead of a potential submission to the FIA World Motor Sport Council in December.
