Summary: ETA Green Power has launched the ETA-MODEL 20, a fully integrated 3-in-1 electric powertrain that combines motor, controller and onboard charger into a single 13.5 kg unit. Designed in the UK and manufactured in India, the system targets vehicles with gross vehicle weights from 300 kg to 2,500 kg across urban, commercial, marine and off-road applications.
Key engineering takeaway: The ETA-MODEL 20 delivers 92% peak system efficiency, up to 10,000 RPM motor speed and 37% gradeability at GVW, while achieving a 32.5% reduction in system weight compared with conventional architectures through integration of motor, controller and charger. Notably, the motor is designed without heavy rare earth elements such as terbium and dysprosium, which reduces exposure to constrained HREE supply chains while maintaining the performance envelope typically associated with rare-earth-dense permanent magnet machines.
Why it matters: Integrated 3-in-1 powertrain architectures reduce vehicle-level complexity, wiring, thermal losses and vendor count — all increasingly important for OEMs targeting lower-cost EV platforms and light commercial segments where packaging and BOM cost dominate design decisions. The HREE-free magnetic design also aligns with a broader industry push to de-risk motor supply chains from Chinese rare earth export controls, making the architecture relevant well beyond its immediate light-vehicle target segments.
ETA Green Power develops 3-in-1 HREE-free EV powertrain
ETA Green Power enters the launch phase of the ETA-MODEL 20, a next-generation integrated electric powertrain system designed to redefine efficiency, performance, and simplicity for electric vehicles across global markets. ETA Green Power has developed the ETA- MODEL 20 as a fully integrated 3-in-1 solution, combining motor, controller, and charger into a single compact unit. Designed in the UK, licenced or manufactured in-house, the system delivers a highly optimised, scalable solution for OEMs seeking improved performance, lower costs, and simplified integration.
“At ETA Green Power, we believe the future of electric mobility lies in intelligent system integration,” said Alex Bamberg, Executive Chairman at ETA Green Power. “The ETA-MODEL 20 represents a major leap forward, offering OEMs a lighter, more efficient, and cost-effective powertrain solution without compromising on performance.”
Performance Envelope: 92% Efficiency, 10,000 RPM and 37% Gradeability
Engineered for Performance and Efficiency
The ETA-MODEL 20 system has been developed to push the boundaries of electric powertrain optimisation. Key performance highlights include:
- 92% peak system efficiency
- Up to 10,000 RPM motor speed, exceeding typical market alternatives
- Up to 37% gradeability at GVW, supporting demanding operating conditions
- Significantly reduced noise, vibration, and harmonics for smoother operation
- Advanced thermal management, maintaining high performance even in extreme environments
The system is designed for vehicles with gross vehicle weights ranging from 300 kg to 2,500 kg, making it suitable for a wide range of applications across urban and commercial mobility.
Compact, Lightweight, and Cost-Effective
With a total system weight of just 13.5 kg, including the onboard charger, the ETA- MODEL 20 is substantially lighter than conventional systems, which typically weigh up to 20 kg. Its compact footprint, approximately 20% smaller in volume, enables greater design flexibility for OEMs.
By integrating multiple components into a single unit, ETA Green Power reduces the need for complex wiring, lowers thermal losses, and simplifies supply chains. This results in:
- 32.5% reduction in system weight
- 20% lower overall vehicle-level costs
- Fewer components and reduced vendor complexity
- Improved reliability through single-system ownership
HREE-Free Motor Design: Eliminating Terbium and Dysprosium
Sustainable and Future-Ready Design
The ETA-MODEL 20 is engineered without the use of heavy rare earth elements (HREE) such as terbium and dysprosium, ensuring greater supply chain stability and reducing exposure to geopolitical risks. This approach supports a more sustainable and resilient electric mobility ecosystem.
Manufactured in India with a focus on durability and real-world conditions, the system is built to perform reliably across diverse and challenging environments, with IP67-rated protection for enhanced durability.
A New Standard for OEM Integration
ETA Green Power’s vertically integrated approach, from design and development to manufacturing, provides OEMs with a one-stop solution that ensures quality, predictability, and seamless system integration.
“The ETA-MODEL 20 is not just a product, it’s a platform for the future of electric mobility,” added Alex Bamberg. “By reducing complexity while increasing performance, we are enabling our partners to accelerate time-to-market and deliver better vehicles to their customers.”
With the launch of the ETA-MODEL 20, ETA Green Power reinforces its commitment to innovation, sustainability, and customer-centric design, setting a new benchmark for integrated EV powertrain solutions worldwide.
In parallel with the launch, ETA Green Power is currently in the midst of a funding round to support its next phase of growth and global expansion. The introduction of the ETA-MODEL 20 significantly broadens the company’s addressable market, opening up new opportunities beyond traditional automotive applications, including marine, off-road, and on-road sectors. With its compact, integrated architecture and high-performance capabilities, the platform is well positioned to meet the evolving demands of multiple electrification segments, enabling OEMs across industries to accelerate their transition to clean, efficient electric powertrains.
