ZF AxTrax 2 LF Electric Portal Axle Order Boosts India Electric Bus Market

ZF Friedrichshafen AG has secured a major multi-year contract in India for its advanced AxTrax 2 LF electric portal axle, marking a significant development for the country?s electric bus ecosystem. The agreement covers several thousand units of the AxTrax 2 LF electric portal axle for deployment in battery-electric city buses serving both domestic operations and export markets. First deliveries are scheduled for 2026, positioning the electric portal axle as a key component in upcoming large-scale fleet electrification programs.

Major AxTrax 2 LF Electric Portal Axle Order for India

The multi-year order comes from a leading OEM in India and reinforces the growing demand for high-efficiency electric portal axle solutions in commercial vehicle applications. The AxTrax 2 LF electric portal axle will power a new generation of battery-electric city buses designed for urban mobility and international markets.
The contract includes the supply of several thousand units, underlining confidence in ZF?s integrated electric axle technology. By combining propulsion, braking, and suspension in one compact assembly, the electric portal axle supports optimized vehicle packaging and enhanced passenger capacity.

Efficiency Gains and Cost Benefits for Battery-Electric City Buses

Compared to its predecessor, the AxTrax 2 LF electric portal axle delivers up to 20% greater energy efficiency. These improvements translate directly into lower operating costs for fleet operators and reduced battery capacity requirements in battery-electric city buses.
Higher system efficiency also enables extended driving range, a critical factor in urban transport networks. With the electric portal axle reducing energy losses, operators can optimize total cost of ownership while maintaining performance standards required for intensive city duty cycles.

Impact on Range and Battery Optimization

Improved drivetrain efficiency allows battery-electric city buses to either extend daily range or operate with smaller battery packs. This flexibility supports cost reduction strategies while preserving passenger space, as the compact electric portal axle frees up additional room for battery placement.

Advanced Technology Inside the Electric Portal Axle

The AxTrax 2 LF electric portal axle integrates dual PSM hairpin motors and an 800 V SiC inverter within a low-floor configuration. This architecture enables up to 360 kW of continuous power and peak torque of 36,800 Nm, meeting the demanding requirements of urban bus operations.

Dual PSM Hairpin Motors and 800 V SiC Inverter

The dual PSM hairpin motors enhance power density and thermal performance, while the 800 V SiC inverter improves switching efficiency and reduces electrical losses. Together, these systems strengthen the overall performance of the electric portal axle in battery-electric city buses.
Advanced oil cooling further supports sustained output under high-load conditions, ensuring durability and reliability in dense urban environments. With this integrated approach, the AxTrax 2 LF electric portal axle positions itself as a scalable solution for next-generation commercial electric mobility in India and global markets.
