Next generation torque distribution
Increased safety​ & stability
Maximum performance and handling
Highly customizable
Torque vectoring for high-performance applications
100% of the torque power each motor generates is individually managed for the according wheel, maintaining maximum traction and driving performance to master the most challenging conditions.
Engineering flexibility independent of powertrain types
Regardless of the EDU Model, our eTV software is adapted to the individual drivetrain needs. Our Torque vectoring does not need complex gearing & mechanical solutions.
Highest safety for passengers in dynamic situations
Vehicle response is optimally adapted to driving speeds – more agility at low speeds and maximum stability at high speeds. Our technology allows individual torque control and management with full ESP & ABS functionality complying with the latest Automotive Standards.
Aiding autonomous driving functions
Assistance systems and autonomous driving software can take full advantage of the new functionalities introduced by our e-torque vectoring – raising safety to the highest level with precise maneuverability.
Application Areas
High Performance & Formula Sports Cars
Top driving dynamics, comfort and excellent vehicle stability
Commercial vehicles
Superior maneuverability for urban delivery services and municipal vehicles
Off-Road Applications
Realization of advanced AWD functions for highest all-terrain capability, including agricultural operations
Autonomous Driving Cars
Ultimate safety in all driving situations combined with the highest maneuverability, stability, and comfort

Difference to a conventional differential distribution

In a conventional solution the driving power (torque) is 50/50 to each wheel – whether its a rear- or a front-wheel-drive. So, the total traction of the vehicle is limited by the wheel with the lowest traction. Some other technologies such as limited slip differentials (LSD) or clutch-based torque vectoring systems help to improve the handling of the car on slippery surfaces, however the efficiency, drivability and the experience for the driver are only possible with full e-Torque Vectoring systems, because here, the electric motors´ advantage lies in faster response time and more flexibility in the direction of the torque transfer. This makes Torque Vectoring a natural fit for electrification of vehicles.

High-performance with the active "yaw moment"

Quick and adequate response of the powertrain in the vehicle is one of the main contributors to its driving performance on the most provocative road shapes and during critical traction situations. The technology helps to counter balance any power "oversteer" or "understeer" on either side and provides the most responsive rotation in the right moment. It allows one wheel on an axle to go slower or faster than another, keeping the car steady.
