9 July 2021, 00:49:20

The 4th generation of the Electronics Motor Reducer (EMR4) offers high power density, compact dimensions, and low weight. Utilizing the development and industrialization expertise from the successful EMR3 and previous models, the new platform shows a high level of integration, modularization, scalability, and standardization. This allows vehicle manufacturers worldwide to offer different power levels of the drive-in one model without having to touch interfaces or mounting points.
Compared to the EMR3, which is used in multiple award-winning vehicles, the EMR4 is even more energy efficient. It weighs 25% less at the same power level and is further cost optimized. It also surpasses the current third generation by delivering up to 5% increased efficiency of the whole axle drive, significantly greater power scaling between 80 kW and 230 kW.
The EMR4 will be manufactured in China among other places, based on a local network of supplying partners. Design for manufacturing will make it possible to produce every variation of the EMR4 platform on one production line. The production at Tianjin, China, will deliver the new drive to both local and international carmakers.
