This week, ZF presented its latest technologies for city, intercity, and coach buses, aimed at making passenger transport safer, smarter, and emission-free. A major highlight was the debut of new powertrain health-monitoring software. Initially available for the new AxTrax 2 LF electric portal axle, the system analyzes powertrain data for fleet operators and vehicle manufacturers. This software solution enables real-time condition monitoring, increasing vehicle uptime and lowering total cost of ownership through early fault detection and predictive maintenance alerts.

This software solution enables real-time condition monitoring, increasing vehicle uptime and lowering total cost of ownership through early fault detection and predictive maintenance alerts.
Also on display was the CeTrax 2 dual electric central drive for intercity and coach buses. With a continuous output of up to 380 kW and an efficiency rating of at least 94.5%, the system is designed for demanding long-haul routes and optimized for high performance.
Additionally, ZF introduced the new A134 driven rear axle. It was developed to meet the increased weight and torque requirements of future vehicle platforms, whether conventional or electrified. The axle offers improved regenerative braking capabilities and a reduced weight, while remaining compatible with existing mounting points. This allows the A134 to support higher vehicle efficiency, better energy recovery, and greater integration flexibility.
Furthermore, the innovative e-comp Scroll air compressor from ZF's Commercial Vehicle Solutions (CVS) division was honored with the 2026 International busplaner Sustainability Award. Specifically developed for medium- and heavy-duty hybrid or battery-electric commercial vehicles, the oil-free system utilizes scroll technology to provide exceptionally low-noise and low-vibration air compression. Noise emissions are approximately 67 dB(A) at a nominal output of 250 liters per minute—comparable to the noise level in a typical office environment.
