不使用汽油内燃机不仅减少排放，它也将有更多的选择对车辆实行电子控制。
一种新的体系已经设计完成，它整体集成了传动系统，转向器，减震器和直接置入汽车车轮里的刹车装置，取代原有的带有液压减震器的传统车轮悬架，机械式转向器，液压制动装置和普通电动马达，这种设计提高了燃油里程，更加安全、方便。
这个被称为“ecorner”的电动汽车概念系统，西门子VDO公司期望它允许传统引擎架构被电动轮毂电机取代，这种电机将会直接作用于车轮来加速车辆。四个轮毂电机将独立运作，提供极富动力的驾驶性能。
“ecorner”电动汽车概念系统，将使得开发传动系统，转向系统和刹车装置共同为司机提供支持的车辆成为可能，在危急驾驶的情况，帮助司机避免意外事故。
电动机
有了“ecorner”系统，电动机将确保车轮和路面接触。有了新的悬架，可以减除液压转向系统，每个单独的车轮可以被移动到它自己的特定转向角。当车速降低时，轮毂电机作为辅助刹车，可以起到发电机的作用，用这种方式创造的能量可以用来给车用电池充电。最后，除了电机制动以外，电子楔块刹车装置能够以最大的精确度和巨大的制动力使每个车轮独立减速。
西门子VDO汽车集团副总Klaus Egger博士说：“混合动力驱动只是未来推进方案道路上的一个中间步骤，我们认为电动机将会成为现实长期的驱动动力的解决方案，因为它能够满足未来最严格排放法规要求。”
从内燃机汽车到智能电动车的完全改变，给驾驶员和汽车制造商都带来益处。预计使用轮毂电机后用于汽车推进的能量可以达到总能量的96%。这将使得汽车制造商更容易满足排放法规，同时为顾客提供极富动力的车辆，并且具有优良的燃油经济性。
该系统给驾驶员带来了各种可能。利用电动转向助力和控制每个车轮的加速度，能够使车辆在危险状况下更加稳定。车主的成本也将降低，因为使用更少的部件、减除了液压系统，将减少磨损，并使得保养更加简单。
该系统因为不再需要中心电机从而展现了其在汽车设计革新方面的潜力。
Eliminating internal combustion engines that burn gasoline will not only reduce will also increase the options for controlling vehicles electronically.
A new system has been designed to integrate drivetrain,steering, shock absorbers and brakes directly into the wheels of cars. Replacing conventional wheel suspension with hydraulic shock absorbers,mechanical steering,hydraulic brakes and an electric drive motor,the design promises improved fuel mileage,enhanced safety and greater convenience.
Siemens VDO expects its system,called ecorner,to allow traditional engine architecture to be replaced by electric wheel hub motors,which act directly on the wheels to accelerate the car. The four wheel hub motors will operate independently,offering extremely dynamic driving.
The ecorner system will make it possible to develop vehicles in which drivetrain, steering and brakes provide common support for the driver in critical driving situations, helping to avoid accidents.
Electric motors
With ecorner,electric motos will ensure contact between the wheel and the new suspension, hydraulic steering can be eliminated and each individual wheel can be moved to its own specific steering the speed is reduced,the wheel hub motors act as auxiliary brakes using a generator rgy created in this manner can be used to charge the vehicle y,in addition to the generator brakes,the electronic wedge brakes can decelerate each wheel separately, with maximum precision and enormous braking power.
Egger, group vice president of Siemens VDO Automotive says:"Hybrid drives are only an intermediate step along the path to future propulsion solutions. We consider the electric motor to be the actual long-term drive solution for fulfilling even the most stringent emission laws of the future."
The changeover from cars with internal combustion engines to intelligent electric vehicles will bring benefits for drivers as well as manufacturers. Wheel hub motors are predicted to use up to 96 per cent of their electrical energy for vehicle will make it much easier for automobile manufacturers to satisfy emissions regulations,while simultaneously offering extremely dynamic vehicles with excellent fuel economy.
The system opens up new possibilities for electronic steering aids and controlled acceleration of individual wheels will enable better vehicle stabilisation in hazardous costs for car owners will also be reduced , as using fewer components and eliminating hydraulic systems will reduce wear and service complexity.
The system also has the potential to revolutionise vehicle design by eliminating the need for a central motor.
