Integrated electric mobility and safety solutions for the commercial bus sector

The transition toward zero-emission public transportation requires comprehensive driveline and safety architectures that optimize the total cost of ownership. The deployment of integrated electric axles and advanced driver assistance systems (ADAS) addresses these operational challenges for transit authorities and commercial fleet managers. At the Busworld Türkiye 2026 exhibition, which took place from May 29 to May 31, 2026, ZF demonstrated its latest technology portfolio designed to streamline vehicle operations and support sustainable public transit.

Electric driveline efficiency and condition monitoring
Maximizing the operational range of battery-electric buses relies heavily on the efficiency of the power delivery system. During the trade show, ZF showcased the AxTrax 2 LF electric portal axle, designed specifically for low-floor city buses. This system delivered an average energy consumption savings of 20% in standard SORT (Standardized On-Road Test) cycles compared to its predecessor. This efficiency gain allows operators to either reduce onboard battery capacity requirements or extend the vehicle's functional range.

The mechanical hardware is paired with ZF's new health check software-as-a-service (SaaS). This diagnostic platform remotely analyzes e-drive data to enable continuous condition monitoring and early fault detection, directly improving vehicle availability.

Additionally, the exhibition featured the e-comp Scroll air compressor, an oil-free system engineered for medium- and heavy-duty hybrid, battery-electric, and fuel-cell vehicles. Utilizing two interlocking scrolls, the compressor generates compressed air at a nominal operating point of 250 liters per minute. Crucially for electric vehicles, noise emissions are limited to approximately 67 dB(A), supporting the strict Noise, Vibration, and Harshness (NVH) requirements necessary as electrified commercial vehicles become inherently quieter.

Advanced driver assistance and digital telematics
In the area of active safety, ZF presented its suite of advanced driver assistance systems compliant with the latest General Safety Regulation (GSR II). Rather than relying on isolated features, this scalable ADAS portfolio combines camera, radar, and software functions into a coordinated vehicle motion control system. The integrated functions include Intelligent Speed Assist, a Blind Spot Information System, a new Driver Monitoring System, and Event Data Recorders.

To bridge the gap between physical hardware and fleet management, the company highlighted ZF Bus Connect. Developed explicitly for bus applications, this telematics solution links multiple vehicle domains—including the driveline, braking, and auxiliary systems. Recent software implementations introduced extensive battery analytics alongside condition monitoring for drivetrain solutions like the AxTrax 2 LF, enabling data-driven optimization and predictive maintenance strategies.

Reflecting on the exhibition, Frank Burkhart, Senior Vice President of Sales Bus & Coach at ZF’s Commercial Vehicle Solutions division, noted that the company's focus remained on aligning electrification, safety, and digitalization into integrated systems. Backed by a global development network, this approach allows OEMs to reduce integration efforts while scaling innovative technologies efficiently.

Within the global commercial vehicle market, the transition to electric drivetrains has intensified competition among Tier-1 suppliers. Transit OEMs increasingly demand "plug-and-play" solutions that reduce the engineering overhead required to integrate separate motors, inverters, and axles.

In the electric axle segment, ZF's AxTrax series competes directly with solutions from Dana Incorporated, which offers the Spicer Electrified e-Axles, and Allison Transmission's eGen Power portfolio. Both competitors focus heavily on fully integrating the electric motor and inverter directly into the axle housing to free up chassis space for battery packs. Scania and Volvo Buses also develop proprietary electric drive solutions, though these are typically locked into their respective vehicle ecosystems.

The technical distinction of ZF’s demonstrated portfolio lies in its software-defined architecture. By coupling a highly efficient mechanical portal axle with proprietary SaaS condition monitoring and the dedicated ZF Bus Connect telematics ecosystem, ZF provides a turnkey solution. This allows independent bus manufacturers to bypass the complex integration of third-party telematics and diagnostic software, offering a unified ecosystem from the road contact patch up to the cloud-based fleet management dashboard.
