New energy buses were first launched pilot run in Pudong. 75 units of diesel-motor hybrid buses have been launched to 5 lines as No. 119, No. 610, No. 779, No. 785 and No. 792, which occupy half of pilot run buses in Shanghai. These buses are only driven by two dynamic systems of internal-combustion engine and electric motor. Diesel motors are shut in the process of starting and low-speed drive; in the process of speed reduction, the hybrid system exchanges unnecessary energy into electric power and stores it in batteries, which largely reduces gas emission. Meanwhile, 9.6-km Expo Park super-capacitor Puming Line facilities have been set up invested by Pudong New Area District Government in Expo Park. Currently, Euro III and Euro IV standard buses have occupied 60% of Pudong New Area District transportation lines. New energy buses have also been promoted for application.
