We are the motor for the mobility of today and tomorrow

About us

SEG Automotive Spain (factory of Treto) has been dedicated throughout its history to the production of components for the automotive industry, becoming a worldwide reference for the effectiveness of its processes and the quality of its production.
For 40 years it was part of the Bosch Group within its division of generators and starter motors.
On January 2018 the Chinese ZMJ Group acquired this division from Bosch and founded the company SEG Automotive. ZMJ is listed on the Shanghai and Hong Kong stock exchanges.

The factory of Treto maintain a privileged position within the SEG Group as a leading plant for the manufacture of generators, producing 4 million generators per year. Treto is located in a unique natural environment and occupies an area of 265,500 m2.
Caring for the environment is another priority for SEG Automotive Spain, both because of the environment in which our plant is located and because of the efficiency of our products. These have evolved from an efficiency of 72% to the current 85%.

With over 7,000 employees in 14 countries in the world’s most important automotive markets, our global team combines the highest levels of engineering and production competence – and works closely together across cultural and national borders.
This cross-location cooperation not only offers each individual employee unique opportunities to advance their career. It also enables us to consistently find the right answers to changing requirements and implement new ideas quickly. The result: competitive products and a sustainable, balanced growth – across all regions and product categories.
We deliver solutions for today’s and tomorrow’s market requirements. More than 100 years ago, our starter motors and generators revolutionized how vehicles are used in everyday life.
As inventors of Start/Stop and pioneers of 48V mild hybridization, we make present day combustion engines considerably more efficient and climate-friendly.
Inspired by our passion for innovation, we are working tirelessly to extend our technological leadership to e-mobility and develop competitive products for the future of transportation.
In all our actions, we are pursuing a clear goal: to significantly reduce global CO2 emissions with our solutions.

As a global supplier, we combine flexible on-site development and manufacturing with global know-how and mature processes in purchasing, production and logistics. We have established trusting relationships with many of our customers over decades, and our system knowledge enables us to contribute to the development process from an early stage.

As a technology leader for starters and alternators as well as for 48V mild hybridization, SEG Automotive is an expert in the field of rotating machines. From 12V to 48V to high voltage e-machines, we are your ideal global supplier to increase your powertrain efficiency.
Our broad, flexible and scalable product portfolio offers you reliable electrification solutions on an industrial scale. Whether your goal is full electrification or cost-effectively optimizing your fleet consumption to meet CO2 legislation targets, we have the right e-machine for you – for both passenger cars and commercial vehicles.
Our products meet the toughest requirements for various engine types and application scenarios: long operating times, dust, mud, water, hot and cold temperatures – we have you covered.

Our experience in developing e-machines and producing them on an industrial scale dates back more than 100 years. OEMs (Original Equipment Manufacturers) around the world value us as a reliable long-term business partner. They benefit from our global production network, which delivers high-performance, durable and competitive products with uniform quality standards.
We combine global customer teams with on-site application development and local partners. From the performance specification to the start-of-production and post-series support: We are at your service to shape the future of mobility together!

Mild hybrid:

Our Boost Recuperation Machine (BRM) transforms any conventional internal combustion engine into an efficient mild hybrid with minimal effort.
Simply ‘swapping’ in the BRM on the belt drive (P0) already brings up to 15% CO2 savings. These can be boosted even further with our Electric Machine (EM) 48V Platform. It can be flexibly integrated into any powertrain, for example on or in the transmission as well as on the rear axle, and power additional driving features and a reduction in CO2 emissions of up to 25%.
We also offer a dedicated series of 48V e-machines for two- and three-wheeled light vehicles, which enable them to drive completely emission-free and significantly reduce urban pollution.

High voltage:

We are a driver of this transformation thanks to our many years of experience in the production of e-machines.
Our efficient high voltage automotive e-machines are based on more than 100 years of experience in developing and producing rotating machines.
At SEG Automotive, we commit ourselves to an electrified future of mobility. Given today’s challenges of the greenhouse effect and air pollution, electrification of the powertrain is essential for the automotive industry.

Products

Four product groups – one shared quality: reliable efficiency.

High Voltage E-machines
Our scalable e-motor concepts enable rapid adaptation of high-voltage e-machines to various customer applications – from light-weight motors for auxiliary units such as air-conditioning compressors to high-powered engines and components for passenger cars and commercial vehicles.

48V E-machines
Plug&play solution for higher efficiency: Our 48V E-machines save up to 25% CO2 by hybridizing conventional powertrains and can enable full electrification of light vehicles.
Our Boost Recuperation Machine (BRM) transforms any conventional internal combustion engine into an efficient mild hybrid with minimal effort: by replacing the 12V generator with the 48V BRM, fuel consumption and CO2 emissions are reduced significantly.
The EU has officially recognized the BRM as an eco-innovation, which enables manufacturers to receive additional CO2 credit and further reduce their fleet consumption.

Generators
SEG Automotive offers a broad range of high efficiency generators for any power requirements, which keep the vehicle’s electrical system stable despite a growing number of electrical consumers and contribute to reaching CO2 targets.

Starter motors
Reliable start at desert or arctic temperatures, in start/stop mode at high speeds or with frequent re-starts for delivery vehicles: Our starter motors for passenger car and commercial vehicle satisfy even the toughest demands.
