Valeo 48V 2-Speed eAxle Powers Dacia Hybrid-G 150 4x4 Models with Electrified AWD

Valeo has commercially introduced its new 48V 2-Speed eAxle featuring Smart Dog-Clutch technology, marking a significant step in affordable electrified all-wheel-drive systems. The newly launched solution will be deployed in the Hybrid-G 150 4×4 powertrain used by Dacia across the Duster, Bigster, and the upcoming Striker models. Designed to combine electrification with practicality, the system supports efficient vehicle operation while helping manufacturers comply with increasingly stringent emissions requirements across Europe.

The disconnectable 48V 2-Speed eAxle integrates bi-fuel petrol and LPG technology with an electrified four-wheel-drive architecture. Weighing 41 kg, the compact unit delivers a peak power output of 31 hp. By replacing conventional mechanical driveline components with an electric rear axle, the system contributes to lower emissions while maintaining the functionality expected from modern AWD vehicles. The approach offers a cost-effective pathway toward electrification without requiring a full battery-electric platform.

Key Specifications of Valeo’s 48V 2-Speed eAxle

The newly launched eAxle combines compact packaging, torque delivery, and efficient drivetrain operation for hybrid vehicles requiring all-wheel-drive capability.

Co-Development with Renault Group

The technology was jointly developed by Renault Group and Valeo to provide a practical balance between performance and efficiency. The drivetrain is capable of generating up to 1,800 Nm of torque at the rear wheels when operating in the short gear ratio. During higher-speed operation, the system automatically transitions to the long gear ratio, enabling efficient vehicle performance at speeds reaching 140 km/h. This dual-ratio configuration allows the drivetrain to optimize traction and energy utilization across varying driving conditions.

Enhanced Urban Driving Efficiency

For the Duster and Bigster models, the electrified rear axle significantly increases electric driving capability. Under WLTC conditions, the system allows as much as 60% of urban driving to be completed in fully electric mode. This contributes to lower fuel consumption and reduced tailpipe emissions during city operation. The architecture demonstrates how hybrid systems can improve efficiency while preserving the versatility required by customers seeking four-wheel-drive vehicles.

Designed for Real-World Durability

The 48V 2-Speed eAxle has been engineered to operate reliably in demanding environmental conditions. The system maintains functionality across temperatures ranging from -30°C to 45°C, supporting use in both cold and hot climates. Importantly, the electrified drivetrain does not negatively impact towing capability or water-wading performance, ensuring that vehicle utility remains intact. This combination of durability, efficiency, and AWD functionality positions the technology as a practical solution for future hybrid vehicle applications.
