Concepts
Cars that are kinder to the environment
•  Saves energy Fuel consumption reduced
•  Harmful exhaust gases reduced Nitrous oxides (NOx) and particulate matter (PM) reduced by approximately 60%
•  Lower noise level Engine noise reduced by approximately 30dB.
(The engine is turned off during stops at stations)

Information about the hybrid system is displayed on the driver's cabin monitor
Reduced maintenance
•  Parts from electric railcars are used, and they require less maintenance
•  There are fewer parts that require maintenance (such as transmission components)
•  Hot water and refrigerant piping are eliminated through use of electric heating and air conditioning
•  Components requiring less maintenance are used (e.g. auxiliary power unit, inverter, converter, motor)
