What YASA does
YASA Limited develops and manufactures axial flux electric motors and motor controllers for high-performance automotive, aerospace, and marine applications. The company was founded in 2009 by Dr. Tim Woolmer as a spin-out from the University of Oxford, commercialising a proprietary Yokeless And Segmented Armature (YASA) topology that removes the stator yoke and splits it into segments to reduce weight while increasing torque, power density, and efficiency. YASA's motors deliver up to 4x the performance and are approximately 50% smaller and lighter than conventional radial flux designs, with a world-record 59 kW/kg power density achieved in October 2025 using no rare-earth materials. The core product portfolio includes the P400 and 750 motors, volume YM360/YM720 series motors, the Si400 controller/inverter, and an in-wheel motor under development with Domin and Cranfield University.
YASA operates as a Tier 1 supplier selling directly to OEMs through long-term enterprise contracts and joint innovation agreements, with pricing not publicly disclosed. Its automotive customer base spans luxury and performance OEMs including Ferrari (SF90 Stradale, 296 GTB; reportedly ~75% of Ferrari supercars), Lamborghini (Revuelto, next-gen hypercar), Koenigsegg (Regera), and Mercedes-AMG (GT 4-Door, AMG.EA platform). The company also serves aerospace (Rolls-Royce Spirit of Innovation) and marine (EVOA Propulsion, Jaguar Vector V20E, Griffon Hoverwork). Since July 2021, YASA has been a wholly owned subsidiary of Mercedes-Benz AG, supplying the AMG.EA electric platform while retaining its own brand, team, and UK-based operations.
Manufacturing is anchored by a £12m, 100,000 sq ft super-factory in Yarnton, Oxfordshire (opened May 2025, capacity beyond 25,000 units/year), with additional R&D facilities in Welshpool, Wales, and mass production at Mercedes-Benz's Berlin-Marienfelde plant. A new 88,000 sq ft UK headquarters at Bicester Motion is under construction on a 15-year lease for January 2026 completion. The company employs 400+ people and is funded primarily through Mercedes-Benz ownership, supplemented by £28.2m of UK government Advanced Propulsion Centre grants (2023-2024) for in-wheel motor and inverter development.

YASA competitors and assessment
Company assessmentDirect peers
- Saietta Group: UK-based axial flux motor developer focused on light electric mobility (e-scooters, motorbikes, marine). Most directly comparable startup competitor with the same axial flux architecture and similar Oxford-area roots. Smaller scale than YASA but pursues the same technology category.
- Magnax: Belgian axial flux motor startup targeting EV and wind applications with yokeless axial flux topology similar to YASA's. Direct technology competitor, though earlier-stage and at smaller scale.
- Lucid Motors: US luxury EV manufacturer that develops its own in-house axial flux motors at scale. Uses its own proprietary axial flux technology across the Lucid Air and Gravity platforms, making it both a technology competitor and a benchmark for axial flux at production scale.
Emerging players
- Equipmake: UK-based developer of electric motors and powertrains for buses, trucks, and aerospace applications. Smaller scale than YASA, focused on spoke-type permanent magnet motors rather than axial flux, but operates in adjacent UK EV motor ecosystem.
- Turntide Technologies: Developer of switched reluctance electric motors for HVAC, industrial, and EV applications. Competes in the broader advanced EV motor space with a different topology (switched reluctance) but targets similar customer pain points around efficiency and torque density.
- Rimac Technology: Croatian high-performance EV powertrain supplier (formerly Rimac Automobili) serving OEMs including Porsche, Hyundai/Kia, and Aston Martin. Develops complete electric powertrains including motors, batteries, and electronics for performance and luxury automotive applications.
- EMRAX: Slovenian manufacturer of axial flux permanent magnet motors and generators for EVs, aerospace, marine, and industrial applications. Smaller-scale direct competitor to YASA with overlapping axial flux product line.
- Hinetics: French axial flux motor startup focused on aerospace and industrial applications, with technology developed from Supelec/GE. Direct technology competitor in the axial flux category with a smaller commercial footprint than YASA.
Broad incumbents
- ZF Friedrichshafen: Global Tier 1 automotive supplier with significant EV motor production including e-axles and electric drive units. Competes indirectly through volume automotive OEM relationships and is a much larger incumbent in the broader motor and powertrain space.
- Bosch: World's largest automotive supplier with a substantial EV motor business supplying OEMs globally. Competes indirectly in the same end-market through volume production of high-efficiency radial flux motors and integrated powertrain systems.
