• 40% lower fuel use: New hybrid powertrain concept built for 100% renewable gasoline The newly unveiled system draws from the H12 hybrid engine concept developed in collaboration. • In a bid to extend the relevance of combustion technology in a lower-carbon era, Horse Powertrain presented a hybrid powertrain concept engineered to run on 100% renewable gasoline. • The first demonstrator vehicle is slated for early 2026, underscoring the company’s intention to move quickly from concept validation to on-road testing. • The reveal places the Geely-linked supplier among leading global players seeking incremental efficiency gains from hybrid architectures even as full electrification accelerates. • Formed in 2024 as an independent supplier, Horse Powertrain consolidated the internal combustion and hybrid operations of Geely and Renault Group. • The joint venture is owned 45% by Geely, 45% by Renault Group and 10% by Aramco, supplying engines and hybrid systems to Renault, Geely Auto, Volvo Cars, Nissan, Mitsubishi Motors and Proton.
Article Summaries:
- Horse Powertrain, a joint venture owned 45 % by Geely, 45 % by Renault Group and 10 % by Aramco, unveiled a new hybrid powertrain that runs on 100 % renewable gasoline. The system, based on the H12 hybrid engine developed with Repsol, achieves a peak brake thermal efficiency of 44.2 % and delivers about 71 mpg under WLTP-roughly a 40 % improvement over the 2023 European average for new passenger cars. The design incorporates a 17:1 compression ratio, optimized turbocharging and exhaust recirculation to maximize combustion efficiency. A mid‑size vehicle equipped with the system could cut CO₂ emissions by ~1.95 US tons per year. Two prototype engines are in validation, and a demonstrator vehicle is slated for early 2026, marking the next step toward commercial deployment.
