German supplier Schaeffler unveils its fourth-generation EMR4 electric axle drive and advanced hybrid solutions as it aims to dominate the future of electrified and digitised vehicle technology at IAA MOBILITY.
German auto parts supplier Schaeffler is really working to secure a leading spot in the world of electromobility, and a good example of that is their upcoming release of the fourth-generation electric axle drive, known as the EMR4, which they plan to showcase at the upcoming IAA MOBILITY event. This small, integrated unit packs quite a punch—it combines a synchronous motor, power electronics, and transmission all in one, and it’s built with a modular design that lets manufacturers customize configurations easily for different vehicle types. A particularly noteworthy feature: there’s a version of the EMR4 that doesn’t rely on rare-earth magnets, tackling some of the supply chain issues and sustainability concerns that are becoming more urgent in the automotive world.
Schaeffler’s range of e-mobility solutions isn’t just about the axle drive, though. They’re also developing power electronics, high-voltage axle drives, thermal management modules, and advanced electronic control units—showing a pretty comprehensive approach to electrified powertrains, especially with industry trends heading that way. The company actually predicts that by 2035, battery electric vehicles (BEVs) will be the dominant propulsion technology. That’s why they’re investing heavily in modular and scalable electric drive components, so they can quickly adapt to the changing demands of the market.
Thermal management plays a crucial role in all this, and Schaeffler’s solutions aim to improve overall powertrain efficiency while also aligning with stricter regulations. Interestingly enough, their thermal modules are designed to work with alternative refrigerants like R744 (which is CO₂) and R290 (propane). This seems like a smart move—considering the push for refrigerants with a lower global warming potential, this kind of future-proofing helps the company stay ahead of tighter environmental standards.
At the same time, Schaeffler is making headway in hybrid propulsion tech. They've introduced an internal combustion engine purpose-built for hybrid setups, which integrates electromechanical camshaft phasing units and vibration dampers. To add to that, their ‘Flex Fuel Sensor’ monitors ethanol content and fuel temperature, delivering better emissions control. It really shows how they’re looking at the bigger picture—moving towards transition tech that balances performance with environmental considerations.
Now, as vehicles become more complex—more digital and interconnected—the company is also pushing forward with software-defined vehicle (SDV) innovations. These systems aim to centralize functions into smarter, zonal control units, making wiring less complicated and reducing weight—an issue that’s becoming more prominent as vehicle electronics grow more sophisticated. Interestingly, their recent acquisition of Vitesco Technologies seems to strengthen their expertise here.
Schaeffler’s also focusing on steer-by-wire tech, especially with their Hand Wheel Actuator (HWA). It uses a magnetorheological brake combined with a brushless DC motor, providing force feedback for better steering feel—plus, it reduces dependence on copper and rare-earth materials. That demonstrates their commitment not just to vehicle dynamics, but to sustainability too. Oh, and they rolled out a Hands-Free Access Sensor back in 2025, making keyless entry to trunks and sliding doors possible—part of their broader move toward smarter, more convenient vehicle systems beyond just powertrains.
Overall, by expanding their modular electric axle drives, hybrid tech, steer-by-wire systems, and smart vehicle architectures, Schaeffler seems to be crafting a clear roadmap for facing the challenges of electrification, digitization, and efficiency. Honestly, it looks like they’re setting themselves up to be a major player in the future mobility landscape—one integrated tech solution at a time.
