ZF has initiated real-world testing of its TraXon 2 Hybrid transmission in heavy-duty trucks across European fleets. The plug-in hybrid system targets substantial CO₂ reductions while preserving operational range and compatibility with existing diesel infrastructure.
Highlights
- Real-world trials confirm CO₂ reductions up to 47% in long-haul and 73% in regional distribution with regular charging.
- TraXon 2 Hybrid maintains full vehicle range using conventional refueling networks.
- System integrates with diesel, HVO, CNG/LPG, or hydrogen combustion engines.
- Positive feedback from BGL members highlights efficiency and infrastructure independence.
Real-World Validation by Fleets
ZF conducted public road demonstrations using its own test vehicle. Participants included European transport operators and members of the German Association for Freight Transport, Logistics and Waste Disposal (BGL) e.V.
Early results validate the transmission’s ability to lower emissions and Total Cost of Ownership (TCO) without compromising daily mileage requirements typical of long-haul operations.
Christian Feldhaus, Vice President of Transmissions & Hybrids at ZF Commercial Vehicle Solutions, stated the hybrid powertrain offers a pragmatic bridge technology until widespread high-power charging becomes available.
CO₂ Reduction Potential and Regulatory Alignment
VECTO simulations indicate:
- Up to 47% CO₂ savings in long-haul cycles
- Up to 73% savings in regional distribution with consistent plug-in recharging
These figures support fleet compliance with 2030 CO₂ targets. ZF advocates for plug-in hybrid trucks to receive toll and weight compensation equivalent to battery-electric vehicles in European systems.
Technical Specifications
The TraXon 2 Hybrid builds on the production-proven TraXon 2 transmission platform.
Key components include:
- Electric motor position: Parallel P2 layout between clutch and transmission
- Voltage range: 600–800 V
- Continuous power: 190 kW
- Peak power: Significantly higher than continuous rating (exact figure not disclosed)
- Operating modes: Pure electric drive, boost assistance, regenerative braking
The modular design enables integration as full hybrid or plug-in hybrid across multiple fuel types, including diesel, renewable HVO, gaseous fuels, and hydrogen combustion engines.
Path to Market Readiness
Production readiness leverages ZF’s existing high-volume manufacturing processes. The system requires no fundamental changes to vehicle architecture, simplifying OEM adoption.
