Pearl River Delta (PRD) is one of the fastest economic development regions in China. The big cities in PRD attract a great many young high-educated immigrants and become over crowded. The number of private cars has been dramatically increasing since the last few years, which creates serious traffic congestion, air pollution and energy shortage. Most young immigrants are living stressfully in these cities due to the low income, high workload and limited personal mobility. They spend hours in commuting. They are surrounded by the “concrete jungles”, where people tend to worship social status and wealth. It is predicted in this thesis that the PRD transportation in 2020 will shift from the currently dominant private cars to more public transportations and bicycles. In order to accord with this sustainable mobility, the Urban Cocoon electric concept car wants to empower people to stay sensible, empathy and connected with others, and rediscover their intuitive needs for personal mobility. This mobility should be sustainable, enable people to keep pace with the rapid life and adapt to the hot and humid weather. Instead of being sold as private cars, the Urban Cocoons will be used as sharing cars, which offer affordable, high-quality personal mobility to the citizens, while limit the impact to the environment. As sharing cars, Urban Cocoons can be easily integrated into the whole transportation system. The body of Urban Cocoon is aerodynamical. The innovative climate control system can dramatically decrease the energy consumption on cooling and enable the occupants stay connected with the natural environment. The sustainable electric Urban Cocoon will become an ideal mobility for the PRD citizens and enable them to have a healthier and happier driving experience.
