A proposal to reintroduce V10 engines into Formula 1 is set to be rejected by the engine manufacturers in the coming week, Afrosport reports.
FIA president Mohammed Ben Sulayem has been backing a plan to bring back the engines once revered for its loud noise, even as F1 is set to move to using sustainable fuels from next season when new engine regulations will come in place.
The plan however needs to be supported by four of the five engine manufacturers (Mercedes, Ferrari, Honda, Audi and Red Bull Powertrains) that will be on the F1 grid next year.
According to BBC Sport, Audi had already indicated its support for the 2026 engine, while Honda, which initially planed to quit F1, also backs the new hybrid engines as it leaves Red Bull to supply Aston Martin from next year.
Mercedes, meanwhile, is open to a new engine formula but wants hybrid elements retained if it is to continue in the sport.
Only Red Bull and Ferrari appear to back the plan but the opposition of Honda and Audi is enough to crush it.
The manufacturers will meet with the FIA to discuss the future of F1 engines at the Bahrain Grand Prix on April 11.
V10 engines became the default power unit in F1 from the mid-1990s until 2005 when the sport switched to V8s, and the current V6 turbo hybrid engines since 2014.
