When combined with the Dedicated Hybrid Engine (DHE) component, the system forms a cost-effective hybrid powertrain, capable of meeting the latest emission regulations while maintaining optimal vehicle dynamics and driving comfort.

Our transmission systems are based on a 4-speed modular concept, developed through a holistic engineering approach. The goal is to find the perfect balance between performance, efficiency, and cost-effectiveness.

Unlike conventional solutions that rely on disc clutches, Dumarey’s system employs dog clutches, specifically chosen to minimize friction losses and maximize mechanical efficiency.

The result is a smooth and reliable gear-shifting experience, with no torque interruption during transitions. Thanks to an EVT (Electric Variable Transmission) mode, the system electronically controls the speed difference between clutch components, ensuring precise synchronization and exceptional driving performance.
