F1, the FIA, the teams and the sport's power unit manufacturers have confirmed an agreement has been reached regarding massive engine regulation changes.

At the start of this year's campaign, F1 welcomed completely overhauled chassis and power unit regulations in a move towards a near 50/50 split between the Internal Combustion Engine (ICE) and the electrical hybrid system.

The electric motor tripled its output to 350 kW and the MGU-H was removed altogether in a bid to promote more overtaking, a reduction of drag and a move towards F1's goal of being Net Zero by 2030.

The introduction of more sustainable F1 engines attracted the likes of PU manufacturers Audi and Honda, but just six races into the new regulations era, F1's governing body have already confirmed a U-turn on their engine stance.

The new regulations weren't introduced without controversy, with four-time champion Max Verstappen publicly sharing his dislike of the sport's new machinery on multiple occasions.

The Red Bull star likened F1 to 'Formula E on steroids' and took issue in particular with the forced energy management, claiming the new cars were 'anti-racing' thanks to the excessive use of lifting and coasting required.

Ahead of the Barcelona-Catalunya Grand Prix however, a move away from the 2026 engine split has been confirmed for 2027 with a goal of reaching 60/40 for 2028.

A statement from the FIA read: "The proposed changes are intended to address issues related to energy management and fuel energy flow characteristics and make qualifying more flat-out while not impacting the positive and exciting racing generated by the new regulations.

"The package introduces a staged rebalancing of Internal Combustion Engine and Energy Recovery System contribution across the 2027 and 2028 seasons. It includes targeted adjustments to internal combustion engine output, fuel energy flow and energy recovery system deployment, together with increased flexibility in energy management."

Supporting measures relating to power unit supply conditions, race operations and financial regulations have also been included in the package of changes, of which the details have not been shared publicly. The FIA will now go through the formal approval process to provide all parties with early clarity and sufficient time to adapt to the revised requirements, with the suggested changes set to be submitted to the World Motor Sport Council for approval on June 23 in Macau.

The below table highlights the FIA's engine change roadmap.
