As the bus and coach industry faces its most significant transformation since the internal combustion engine’s debut, ZF is showcasing its latest innovations at the UITP Summit Hamburg 2025, taking place from June 15 to 18. The company is emphasizing advancements aimed at setting new benchmarks in efficiency and Total Cost of Ownership (TCO) while promoting cleaner, safer, and smarter bus technologies.
ZF’s presentation will highlight its next-generation electric central and axle drives, a newly developed electric air compressor, advanced driver assistance systems (ADAS), and key developments in automated driving technologies.
Driving Public Transportation Transformation
Daniel Majewski, Head of the Product Segment “Bus Solutions” at ZF’s Commercial Vehicle Solutions division, stated:
“At UITP Summit 2025, we are showcasing a broad technology portfolio that supports the ongoing transformation of public transportation. Our expertise spans driveline, braking, ADAS, air management, and digital solutions. With the industry’s most comprehensive range of innovative products, we are a trusted partner for cities, fleet operators, and manufacturers worldwide, helping to deliver safer, smarter, more comfortable, and sustainable mobility services.”
Advancing Decarbonization with Electric Drives
One of the highlights at UITP 2025 is the global premiere of ZF’s electric central drive, CeTrax 2. Designed for buses up to 19 tons, CeTrax 2 offers a continuous output of 210 kW and peak torque of 8,720 Nm, marking a significant step forward in electric driveline performance.
The AxTrax 2 LF, a low-floor electric axle, will also be introduced as the successor to the AxTrax AVE. Featuring ZF’s modular electric drive kit, the AxTrax 2 LF boasts roughly 20% lower energy consumption compared to its predecessor. This efficiency improvement helps operators reduce operating costs while supporting sustainability goals.
Adding to its portfolio of electric vehicle components, ZF will debut the e-comp Scroll electric air compressor. Utilizing a spiral compressor design, the e-comp Scroll offers low noise and vibration—an important advantage for electric commercial vehicles. Its oil-free operation also significantly cuts maintenance demands, improving reliability and cost efficiency.
Citybus CMS: Elevating Safety Standards
ZF will present Citybus CMS, an innovative brake assistance system based on its proprietary OnGuardMAX ADAS platform. The system actively warns drivers and automatically brakes to reduce the severity of potential collisions, exceeding current safety standards for city buses. A dedicated brake cascade system ensures optimal protection for stationary or unsecured passengers during braking maneuvers. Several bus manufacturers have already integrated Citybus CMS into their fleets.
Digital and Automated Driving Solutions
The company’s digital fleet management platform, ZF Bus Connect, will be showcased, focusing on uptime management for electric buses. The system provides real-time driveline and battery status monitoring, cross-system condition analysis, and remote diagnostics to optimize fleet performance.
ZF Mobility Solution also offers engineering and consultancy services to support cities and public transport operators (PTOs) in developing autonomous public transport—from initial tendering to deployment. At the UITP Summit, ZF will share insights from pioneering Level 4 autonomous vehicle projects, including experiences with regulatory approval and operational deployment.
