Electric Vehicles

Electric Vehicle 'Demio EV'
Electric Vehicle 'Demio EV'

Mazda began leasing the Demio EV, an electric vehicle Mazda had independently developed based on the Mazda Demio, in October 2012 in Japan. Using a highly efficient lithium-ion battery and Mazda's unique electric motor, the Demio EV delivers an exhilarating driving experience, including powerful acceleration, precise handling and a comfortable ride. It also achieves an outstanding driving range of 200 kilometers (JC08 mode test cycle, measured by Mazda). The Demio EV maintains the same cabin space and cargo carrying capacity as the base model Demio. As a zero-emissions vehicle that emits no CO2 or other pollutants during driving, Mazda sold 75 units in FY March 2013 mainly to local governments and corporate customers in the Chugoku region. Mazda will continue sales in FY March 2014, with plans to sell approx. 100 total units.

Charging Stations Set Up

Charging Stations

In line with the commencement of Demio EV leasing, Mazda set up charging stations at five locations including the Head Office (Hiroshima) and R&D Center Yokohama. These charging stations, equipped with both fast and normal chargers, are available to not only Demio EV users but also users of other automakers' electric vehicles. By making the stations widely available, Mazda hopes to contribute to improved convenience for local users and residents.

Development of the Hydrogen Rotary Engine

Hydrogen is clean energy that can be generated from various sources. Mazda has already introduced two models incorporating the Mazda hydrogen rotary engine: the Mazda RX-8 Hydrogen RE (leasing started in 2006) and the Mazda Premacy Hydrogen RE Hybrid (leasing started in 2009). When the eco-friendly Mazda hydrogen rotary engine runs on hydrogen fuel, it emits no CO2. It also features a convenient dual-fuel system, so the car can run on gasoline if there is no hydrogen available. In Japan, Mazda has cumulatively delivered twelve of these vehicles on a lease basis to Iwatani Corporation, Hiroshima Prefecture, the City of Hiroshima, and Yamaguchi Prefecture. Mazda also delivered three of these vehicles in Norway and received much praise.

Compatibility with Bioethanol Mixed Fuel

Mixed fuel consisting partly of bioethanol, which is made from plants, is attracting attention in North America and Europe for its effectiveness in reducing CO2 emissions.

Mazda is proud to sell vehicles that are compatible with this eco-friendly fuel.

Current Status

  • Mazda vehicles that are compatible with E10 (gasoline mixed with 10% ethanol) are sold in North America and Europe.
  • In Thailand, Mazda3 models compatible with E20 (gasoline mixed with 20%ethanol) became available in FY March 2008, and Mazda2 models corresponding to E20 became available in FY March 2010.
  • In Japan, models equipped with a SKYACTIV-D 2.2 clean diesel engine that is compatible with B5 (diesel mixed with 5% biodiesel fuel) became available in FY March 2012 for the CX-5 and in FY March 2013 for the new Atenza.
