Formula 1® is moving towards a significant change in its engine regulations planned for 2030, with a focus on simpler and lighter power units. The initial proposal outlines a shift to a 3.0-litre V8 turbocharged engine combined with a smaller electric motor, aiming to reduce complexity while maintaining performance and sound characteristics suited to the sport's diverse circuits.
Key stakeholders in the sport, including the FIA and engine manufacturers, have largely agreed on the main elements of this new engine formula. The naturally aspirated engine option was dismissed, primarily due to noise restrictions at several prominent street circuits such as Melbourne, Miami, Madrid, Singapore, Baku, and Las Vegas. Instead, the plan retains turbocharging but with a smaller turbocharger to balance engine noise and regulatory limits.
The hybrid component will see a notable simplification, with the electric motor's output reduced to 100kW from the current 350kW. This change aims to preserve electrification in the power units but with less technical complexity and a reduced role in overall power delivery. Additionally, the new power units are targeted to be at least 50kg lighter than those currently used, contributing to improved car dynamics and efficiency.
Another notable aspect under consideration is the introduction of a push-to-pass system, similar to the temporary power boost used in IndyCar, which could replace the current Drag Reduction System (DRS) for overtaking assistance. This would represent a shift in how drivers manage overtaking opportunities, potentially adding a new strategic element to races.
The timeline for these changes remains under discussion, with the regulations expected to be introduced around 2030. There is also talk of potentially bringing forward the end of the current technical cycle by a year to accommodate the new rules. All Formula 1® teams and engine manufacturers are involved in these ongoing discussions, reflecting a collective effort to shape the future of power unit technology in the sport.
This direction signals a move back towards a more traditional racing engine concept, reducing the technological complexity that has characterized recent hybrid power units. The balance between maintaining the sport's technical innovation and addressing practical concerns such as noise and weight is central to this development.
While final technical specifications and regulatory details are yet to be confirmed, the 2030 engine plan highlights Formula 1®’s intent to evolve its power units in a way that respects both performance and the unique demands of its global race calendar.
