在汽车设计中，重要的性能基本包括：安全性、轻量化特征、耐用性、可驾驶性、噪声和振动。然而，设计师往往在开发阶段后期才发现性能并不理想，想要做出改变时已经太迟。或者，设计师很难预测新型轻量化材料将对产品性能产生哪些影响。此外，多次设计迭代、重开模具和原型样件方面需要花费的大量时间和费用，这都浇灭了设计师团队的创新灵感。
ESI 的旗舰产品——ESI 虚拟性能解决方案 (Virtual Performance Solution, VPS) 仅仅一个工具，即可释放你的创造力和提高你的效率。
电子传动系统和自主驾驶已经对新车的组件和总体结构产生了影响。由于这些革命性的交通方式，需要 主机厂确保车辆具有同等水平的碰撞安全性、性能（续航里程、轻量化及舒适性）和成本效益。而且，他们现在无法承担对真车进行碰撞、测量和评估所花费的时间和资源，只能回到电脑前设计“改良的”原型样车。主机厂及其供应商必须找到一种方法来满足不断变化的要求——仿真具备这种能力。主机厂能够对各种情景进行虚拟测试，这一点对于确保使用全球化思维方式成功开发一款电动汽车至关重要。
