Battery Electric Vehicles (BEV) are central to automotive manufacturers meeting their CO2 emissions obligations. Also, the sale of new internal combustion engine cars is being phased out. Navigating this transition requires customer acceptance with range a key factor, which is strongly influenced by aerodynamic drag.While BEVs provide new opportunities for lower drag underfloors SUVs must still deliver off-road performance with a rear suspension which is cost-effective, leading it to be exposed to the airflow: a drag and range penalty. Requirements for articulation and off-road robustness mean that conventional undertrays or covers are not effective solutions.This project aims to (1) identify the interactions between underfloor flow, rear suspension, diffuser, wheel and rear wake systems; (2) develop flow control strategies (e.g., vortex generators, deployable, deformable and morphing surfaces) reducing the drag impact of the suspension system, optimising the benefits of a rear diffuser as part of a wake control strategy.

电池电动汽车（BEV）是履行其二氧化碳排放义务的汽车制造商的核心。此外，新的内燃机汽车的销售正在淘汰。导航这种过渡需要范围接受客户接受，这是一个关键因素，这受到空气动力学阻力的强烈影响。虽然BEV为下层地板的SUV提供了新的机会，但仍必须以具有成本效益的后悬架来提供越野性能暴露于气流：阻力和范围罚款。对发音和越野鲁棒性的要求意味着传统的底层或覆盖物不是有效的解决方案。该项目的目的是（1）确定地板流量，后悬架，扩散器，车轮和后尾系统之间的相互作用； （2）制定流量控制策略（例如，可部署，可部署，可变形和变形表面的涡流发生器）减少悬架系统的阻力影响，优化后扩散器的好处，作为尾流控制策略的一部分。
