轮内电机配置可以为电动汽车设计提供更大的灵活性，使汽车更加紧凑和轻便。然而，目前的悬架系统并没有设计成包含轮内动力传动系统，并且研究表明，当更多的非簧载质量被添加到车辆时，行驶舒适性和操纵性变差。为了开发轮内动力系统的纯电动汽车，在考虑了目前汽车中使用的几种后悬架设计方案后，提出了一种新的后悬架设计方案。悬架专为轮内动力系统设计，通过有效利用可用空间，动力系统和电池组的所有部件都可以紧凑地安装在超小型（B级）汽车的有限空间内。该设计还缓解了高簧下质量的一些问题，因为进行了模拟以确定车辆的乘坐舒适性和操纵特性。轮内模块目前正在埃因霍温理工大学进行测试。
The in-wheel motor configuration can provide more flexibility to electric car design, making the car more compact and lightweight. However, current suspension systems are not designed to incorporate an in-wheel powertrain, and studies have shown deterioration in ride comfort and handling when more unsprung mass is added to a vehicle. In order to develop a battery electric vehicle with an in-wheel powertrain, a new rear-suspension design is proposed after considering several designs that are currently used in cars. The suspension is designed specifically for an in-wheel powertrain and, by efficiently using the available space, all the components of the powertrain and the battery pack can be fitted compactly within the limited space available in a subcompact (B-segment) car. The design also mitigates some issues of the high unsprung mass as simulations were conducted to determine the ride comfort and the handling characteristics of the vehicle. The in-wheel module is currently being tested at the Eindhoven University of Technology.
