Traffic congestion is a growing problem in large cities around the world and will continue to worsen as populations increase. The number of vehicles on the road worldwide is expected to quadruple to nearly 3 billion by 2050, while the number of roadways is expected to remain approximately the same in city cores. The average number of occupants of a single vehicle is about 1.6 persons; the space of current vehicles is highly underutilized. To alleviate traffic congestion and associated pollution in large cities, the prevalence of electric urban vehicles are gaining momentum. The advantages of electric urban vehicles are in part due to their versatility; in addition to four-wheel configuration, these vehicles could host a three-wheel configuration with one wheel in the front or rear. The vehicles could also have front, rear, or all wheel steering. In some jurisdictions, narrow urban vehicles are able to lane-split, travel on bike lanes, and park in unconventional spaces. Urban vehicles have a huge potential to relieve traffic congestion and alleviate parking shortages. Urban vehicles in their current form are essentially scaled down versions of passenger cars. This scaled down approach imposes serious limitations on the safety, usability, fuel consumption, thermal loads, power management, and subsequently, customer acceptance of the vehicle. For example, as in conventional passenger cars, existing urban vehicles are designed with the suspension and powertrain external to the wheels that are connected primarily through mounts and mechanical linkages. Therefore, a significant volume is still needed for mechanical components and their connections, which could otherwise be used for added passenger space. It is possible to significantly reduce the space and weight of urban vehicles by integrating the suspension and powertrain into the wheels, and by replacing mechanical linkages with x-by-wire systems. Considering this design approach, the often inadequate interior space of most urban vehicles can be significantly increased. Moreover, this design eliminates many powertrain components and provides more flexibility in aerodynamic body shaping while lowering vehicle mass, all leading to vastly improved energy efficiency. The primary goal of the proposed Discovery program is to develop a new paradigm for urban vehicle technologies to allow the design of highly fuel efficient, safer, and cost effective urban vehicles in a very time efficient process.

在世界各地的大城市中，交通拥堵是一个日益严重的问题，随着人口的增加，交通拥堵将继续恶化。到2050年，全球道路上的车辆数量预计将达到近30亿，而在城市核心中，道路的数量预计将大致相同。单车的平均乘员人数约为1.6人；当前车辆的空间高度不足。 为了减轻大城市的交通拥堵和相关的污染，电动城市车辆的流行正在增长。电动城市车辆的优势部分是由于它们的多功能性。除了四轮配置外，这些车辆还可以在前或后部托管带有一个轮子的三轮配置。车辆还可以具有前，后部或全轮转向。在某些司法管辖区，狭窄的城市车辆能够在自行车道上行驶，沿着自行车道行驶，并将其停在非常规的空间中。城市车辆具有减轻交通拥堵并减轻停车短缺的巨大潜力。 当前形式的城市车辆基本上是缩小乘用车的版本。这种缩小的方法对安全性，可用性，燃料消耗，热负载，电源管理以及随后的客户接受车辆的认可施加了严重的限制。例如，与传统的乘用车一样，现有的城市车辆的设计是悬架和动力总成，主要是通过坐骑和机械连接连接的车轮外部的。因此，机械组件及其连接仍然需要大量的体积，否则可以将其用于增加乘客空间。可以通过将悬架和动力总成整合到车轮中，并用X-By线系统替换机械连接来显着减少城市车辆的空间和重量。考虑到这种设计方法，大多数城市车辆的内部空间通常不足。此外，这种设计消除了许多动力总成组件，并在降低车辆质量的同时提供了更大的灵活性，所有这些组件都可以极大地提高能源效率。 拟议的发现计划的主要目标是开发一个针对城市车辆技术的新范式，以便在非常高效的过程中设计高燃油，更安全和具有成本效益的城市车辆。
