Now, more and more micro-cars are welcomed by consumers, such as Smart, the reason is very simple. In crowded, complex cities, they are easy to control, easy to park, and there is a very good fuel consumption performance, coupled with smart, beautiful appearance, how can not people heart. And today the world's automotive technology research and development team, also began to look to their body. For example. Germany Bremen robot technology innovation center developed a car can be linked to the end of the car, the name of the car is called EO Smart 2, is a can be connected to the end of the car, designed for the future of intelligent city design, the German car Industry has placed high hopes for the future of intelligent traffic. Such as saving energy, because it can greatly reduce the wind resistance, but also can improve road utilization, to avoid rear-end.

If you encounter special traffic, it can also form a truck or a home MPV. Because it is pure electric car, charging is the biggest problem. The EO2 per vehicle is equivalent to a unit module, we string together, you can give low-power vehicles to add electricity. Size only 2.5m × 1.57m, even smaller than the Mercedes-Benz smart. More exaggerated is that the wheel can be rotated 90 degrees, not only sideways to go, but also deformation; In addition, it's this shrink function, can instantly thin, you can deal with parking spaces and other issues ... small footprint, convenient docking.
