Aurobay

What Aurobay does

Aurobay, operating commercially as Horse Powertrain, is a global powertrain solutions company headquartered in Skövde, Sweden, with corporate registration in England & Wales as Horse Powertrain Ltd and approximately 19,000 employees. Founded in 2021, the company designs, develops, and produces integrated powertrain systems and standalone powertrain products for automotive OEMs worldwide, operating across 3 continents with 5 global R&D facilities.

The company's core technology spans combustion engines, hybrid solutions, transmissions, and range extenders. Differentiated products include the X-Range Powertrain Systems—described as the industry's first complete toolkit for adding hybrid capability to BEV-native platforms—the W30 + 4LDHT fusion product combining a lightweight 3.0L V6 engine with a multi-gear dual-motor transmission, and the Amorphous Motor, an innovative motor construction aimed at improving hybrid efficiency. The portfolio is geared toward giving OEMs flexibility across fuel types, regions, and vehicle categories as the industry transitions toward net zero.

The business model is B2B and OEM-embedded. Revenue is generated through three streams: integrated powertrain systems (combining multiple portfolio products), standalone powertrain products (to fill gaps in OEM line-ups), and advanced engineering services tailored to OEM specifications. Pricing is custom and non-public. Named OEM customers include Leapmotor, Chery, and JAC under global-market collaborations announced in October 2025. The company is led by CEO Matias Giannini and has received industry recognition including the Autocar Sturmey Award in June 2026. Geely is listed as a 2022 investor; ownership structure beyond this is not disclosed.
