What HORSE Powertrain makes

HORSE Powertrain develops and manufactures powertrain systems for automotive OEMs: combustion engines, hybrid systems, transmissions, range extenders, and integrated powertrain assemblies. The company organizes its product range into three platform families.

Horse ONE covers combustion powertrain systems -- integrated ICE solutions compatible with gasoline, diesel, synthetic fuels, ethanol blends, and liquefied petroleum gas. Horse FUSION packages HEV, PHEV, and range-extended EV drivetrains for OEMs that need to serve customers across different fuel environments on a shared vehicle platform. Horse X-Range, launched in 2026, is the company's dedicated-EV hybrid toolkit: it allows automakers to add hybrid or range-extender capability to a battery-electric platform without redesigning the base vehicle, targeting OEMs that want to hedge their electric vehicle investment against uneven charging infrastructure. Alongside these integrated systems, the company sells standalone engines, manual and automatic transmissions, hybrid transmissions, and electric motors as separate products.

In 2025 the company presented a future hybrid system (the F15), a compact range extender (C15), and a hydrogen combustion engine at industry events. Per the 2025 Annual Report, HORSE Powertrain produced close to 8 million engines and transmissions during the year, across 18 manufacturing plants.

Two divisions handle operations. Horse Technologies, with 8 plants and 3 R&D centers in Europe and South America, manages ICE and hybrid programs in Spain (Valladolid, Sevilla), Portugal (Aveiro), Turkey (Bursa), Romania (Mioveni), and plants in Brazil, Argentina, and Chile. Aurobay Technologies, the China-based division with 10 plants and 2 R&D centers, traces its lineage to Volvo Car engines and operates facilities in Baoji, Changxing, Chunxiao, Guiyang, and Zhangjiakou among other sites.

Financial performance

Berylls by AlixPartners, in its 2026 ranking of the top 100 automotive suppliers by FY2025 revenue, assigned HORSE Powertrain a revenue figure of approximately €12.6 billion and ranked it 27th globally. Berylls notes no profitability figure is published. The 2025 Annual Report, released by the company, states that 2025 was "a financially strong year" with revenue growth and "solid" operating returns, but discloses no specific revenue, margin, or earnings figure. The Berylls number is an industry forecast, not a company-reported or audited result.

The company employs around 19,000 people across its 18 plants and 5 R&D facilities, per the Annual Report. That figure covers employees in 9 countries. Capital expenditure in 2025 included 40% directed to research and development, per the CEO letter in the same report.

HORSE Powertrain was formed in 2024 as a joint venture and is in its first full years of consolidated operation. The company has not published audited standalone financial statements as of this profile's verification date.

Ownership and history

HORSE Powertrain Limited was incorporated in England and Wales in October 2023 (Companies House number 15239961) and officially launched in May 2024, when Renault Group and Geely completed their joint venture agreement. Each parent holds a 45% stake; Saudi Aramco acquired a 10% equity interest in June 2024, disclosed in an Aramco press release that month. The company is registered at Browne Jacobson LLP, 6 Bevis Marks, London EC3A 7BA.

The industrial base is not new. HORSE Powertrain absorbed Renault's powertrain manufacturing operations -- including plants that had been building Renault and Nissan engines for decades -- together with Geely's powertrain subsidiary Aurobay Technologies (formerly Volvo Car's powertrain arm). This structure gives the company characteristics more like a legacy tier-1 supplier spin-off than a new JV in its capacity-building phase. The company's own description is "125 years of heritage from Renault and Geely," meaning the combined tenure of the legacy operations that make up the JV.

Renault's Valladolid plant (Spain), which builds gasoline and diesel engines for Renault and Nissan models, is among the major legacy assets now operating under the HORSE banner. The Aurobay Gothenburg facility in Sweden, which built Volvo four-cylinder engines, is also part of the group. In 2026 HORSE Powertrain is expanding into the US and India, per the Annual Report CEO letter.

Certifications and quality

HORSE Powertrain holds IATF 16949 certification at multiple manufacturing plants, with certificates posted on the company's own site for the Baoji, Changxing, Chunxiao, and Guiyang facilities in China. The company says IATF 16949 is a group-wide standard. ISO 14001:2015 environmental management and ISO 45001:2018 occupational health and safety certifications are current across the China and Romania facilities, per certificates linked on the company's documents pages. The Romania locations (Mioveni plant and Titu R&D center) hold ISO 9001 and ISO 14001:2015, per the company's Romania documents page.

The 2025 Annual Report includes a quality management section and describes a full development and industrialization cycle managed in-house. The company operates R&D Spain -- a center for project management, design, testing, calibration, and certification of hybrid and diesel powertrains as well as hydrogen and e-fuel work.

Known customers

HORSE Powertrain served around 25 automotive customers globally at year-end 2025, per the 2025 Annual Report. Six are named in the report. Two specific vehicle programs are on the public record: the Renault Grand Koleos SUV sold in South Korea uses a HORSE hybrid engine, and the Geely Zeekr 9X SUV is documented on the company's own site as a customer vehicle.
