Knorr-Bremse has unveiled a new portfolio of zero-emission technologies at IAA Transportation 2026, highlighting a multi-emission strategy that supports battery-electric, hydrogen and other low-emission commercial vehicle platforms rather than relying on electrification alone.
The German supplier’s showcase is led by the debut of its oil-free Multi Tumble Piston (MTP) electric compressor, alongside new braking, steering and air supply technologies designed to reduce carbon emissions, noise, oil consumption and particulate pollution.
Oil-Free Electric Compressor Headlines Product Launch
The new Multi Tumble Piston electric compressor expands Knorr-Bremse’s existing electric compressor portfolio with a modular design intended for different commercial vehicle applications and regional market requirements.
By eliminating the need for oil lubrication, the compressor is designed to improve system efficiency while reducing maintenance requirements and supporting cleaner vehicle operation.
New Steering and Braking Technologies
Knorr-Bremse also showcased an electric power steering (EPS) system scheduled for commercial introduction in 2027.
According to the company, the technology can reduce energy consumption by up to 90% compared with conventional steering systems while providing the technical foundation for future steer-by-wire vehicle architectures.
The company’s new eSilencer technology lowers pneumatic braking noise from 72 dB(A) to 68 dB(A), helping commercial vehicles meet stricter noise requirements in urban and residential environments.
In addition, the liquid-cooled iMEP braking resistor is designed to deliver consistent braking performance regardless of battery charge level, improving operational reliability for electric commercial vehicles.
Flexible Approach to Zero-Emission Transport
Knorr-Bremse said its latest technologies reflect the varying pace of zero-emission vehicle adoption across global markets, where regulatory requirements, infrastructure availability and customer needs continue to differ.
The company aims to provide scalable systems that can support multiple vehicle technologies while maintaining high standards of safety and operational performance.
Bernd Spies, Member of the Executive Board of Knorr-Bremse AG and head of the Commercial Vehicle Systems Division, said the company is focused on helping manufacturers navigate the industry’s evolving transition.
“Zero emissions in road transport remains our clear goal. At the same time, we see very different paces and framework conditions for this transformation around the world. In this environment, Knorr-Bremse is a stable and reliable development partner for commercial vehicle manufacturers. We bring together technology, regulations, and cost-effectiveness—with flexible system solutions on the path to zero-emission commercial vehicles, without compromising on safety and performance.”
