Istanbul Metropolitan Municipality is starting the test drive of electric, environmentally friendly, high-tech, high passenger capacity electric metro buses as of April 1st. Electric metro buses, as well as Autonomous Rapid Transit, which provide a 60% fuel saving compared to diesel metro buses, save 2.5 million Turkish Lira in fuel over 100,000 kilometers. With this investment, the IMM plans to prevent the emission of 300 tons of carbon dioxide, thereby protecting both the environment and the municipal budget. Moreover, the electric metro buses, with a capacity of 420 passengers, will operate quietly, thus also reducing noise pollution in the city.
