As the German firm prepares to unveil the Volkswagen ID.7, its new 100% electric sedan set to replace the Passat, Volkswagen tells us more about its electric motorization, completely new. The Wolfsburg manufacturer presents its new generation of electric motor called APP550 and takes advantage of the group’s MEB platform.

“Since the available space has not changed, we have been forced to develop a new engine that achieves significant improvements in performance and efficiency despite the same limitations. It was a big challenge for the group’s technical and component team. The result shows that we were able to reduce the use of raw materials while achieving a significant increase in vehicle efficiency.”– said Carsten Bennewitz, head of transmission and powertrain development at Volkswagen.

Volkswagen ID. : more power and torque

The new APP550 power unit develops power 286 horsepower and 550 Nm of torque, aimed at the rear wheels, but can be reduced with different power levels depending on the models in the Volkswagen ID family. that he equips.

Technically, this electric motor has been strengthened to achieve this level of high torque and takes advantage of an improved stator, more coils as well as a larger cable cross-section. The rotor is equipped with more powerful permanent magnets, with a greater load capacity.

The inverter has been designed to provide high phase currents to provide increased power and efficiency. It helps to control the drivetrain which has effective operating software. Therefore, the drive can work more efficiently depending on the load phase.

Volkswagen ID. : made in Germany

To increase its efficiency, Volkswagen has optimized a number of transmission components, including the thermal management system. We find there a energy-efficient cooling systemand is able to cool itself.

This new-generation electric transmission will be produced at the Volkswagen Group Components plant located in Kassel, Germanywhich has been producing power units and gearboxes for more than 10 years.

“Based on our many years of experience, we have optimized the entire system due to, in particular, the use of special electrical sheets and individual processing processes, and thus were able to significantly increase efficiency”– says Oleksandr Krik, head of the technical development department of Volkswagen Group Components.
