F1 Accelerates Plans for V8 Engine Return with Sustainable Fuels

Formula 1 is accelerating discussions to potentially reintroduce V8 engines paired with fully sustainable fuels and a simplified hybrid system, aiming to replace the complex 2026 turbo-hybrid power units. A key summit with engine manufacturers and the FIA is scheduled after the Italian Grand Prix to iron out these plans.

Why it matters:

The move is driven by growing concerns over the high costs and intricate technology of the upcoming 2026 power units. This shift promises significant benefits:

• Cost Reduction: Potentially a 65% cut in engine development and manufacturing costs.
• Weight Reduction: New power units could be up to 80kg lighter by removing heavy battery packs.
• Simplicity: Less complicated technology will ease development and maintenance.

The details:

The leading proposal is a 2.4-litre V8 internal combustion engine operating on fully sustainable fuel. This would be complemented by a simplified Kinetic Energy Recovery System (KERS), reducing the electrical contribution to overall power from roughly 50% in 2026 to around 10%. FIA President Mohammed Ben Sulayem and F1 CEO Stefano Domenicali are strong proponents of this direction, seeing it as the future of the sport.

The debate on timing:

While the V8 concept gains traction, the timing of its introduction remains a point of contention.

• FIA's View: President Ben Sulayem desires an earlier switch, potentially before the planned 2030 end of the 2026 regulations.
• Manufacturers' View: Many manufacturers find an early 2029 transition too soon, preferring 2030 or later. This is partly due to the necessity of developing entirely new chassis regulations alongside the engine, soon after the 2026 rule changes.

What's next:

The FIA has called a meeting for September 11 with team and manufacturer representatives. This summit aims to gauge consensus on the proposed V8 concept and determine the precise timeline for its implementation, shaping F1's long-term technical direction.
