Home » BTCC Scrap Hybrid Engines For 2025 Season

The British Touring Car Championship has dropped hybrid and introduced 100% sustainable fuel for the 2025 season.

The Cosworth-developed hybrid was introduced for the 2022 campaign, with restrictions on its usage for the leading contenders in the championship allowing BTCC organiser TOCA to drop its previous success-ballast system.

For 2024, the ‘push-to-pass’ hybrid was augmented by an equivalent power boost from the engine turbo, meaning the increase from usage was effectively doubled to approximately 60bhp.

From 2025, the power boost will remain the same but will come solely from the turbo.

Simultaneously, the BTCC has balanced its ‘green’ credentials with the mandatory usage of 100% sustainable fuel – up from the 20% mixture used this season – as trialled successfully by the Unlimited Motorsport Cupra Leon of Daryl DeLeon at the final two rounds.

TOCA boss Alan Gow told Autosport that the moves came with the full support of the teams.
