Mazda Models Qualify for Eco-Car Tax Reductions
Mazda’s environmentally conscious vehicles are subject to tax incentives in many countries.
In Japan, as of March 2016, 36 Mazda models qualify for the Japanese government’s new ecocar tax reduction*2, implemented in April 2015. Among presently registered Mazda vehicles, around 93% meet the reduction. (Figures based on the number of vehicles shipped in FY March 2016)

*2 An automobile weight tax and automobile acquisition tax reduction are applied when consumers purchase environmentally conscious new cars meeting or exceeding requirements for fuel economy and exhaust gas emissions.
Evolution of Eco Drive Support Technology
The Intelligent-Drive Master “i-DM,” developed by Mazda to encourage drivers to drive in a safe, fun and environmentally conscious manner, was introduced with Mazda’s Japanese models. Since its mounting on Demio in June 2011, Mazda has expanded the number of models fitted with i-DM. In FY March 2016, i-DM was introduced in the Roadster MX-5.
In October 2012 in Japan, Mazda began leasing the Demio EV, an electric vehicle Mazda had independently developed based on the Mazda Demio (Japanese model.). 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 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 and 33 units in FY March 2014 mainly to local governments and corporate customers in the Chugoku region in Japan. Mazda continues addressing various challenges, including longer driving range, based on customer feedback.

Development of the RE Range Extender
One of the biggest problems with electric vehicles is short driving range.
As one of the approaches to resolve this issue, Mazda has been promoting research and development to use, as a power generator, an internal combustion engine applicable to various fuels around the world that are locally produced for local consumption. Mazda RE Range Extender, released in FY March 2014, features a compact and quiet rotary engine shoehorned under the hatchback’s rear trunk floor, enabling its application into the base EV models for an extended driving range without trading trunk area capacity.
Development of Compressed Natural Gas (CNG) Technology
With energy sources becoming diversified and extraction of shale gas increasingly accelerated in the US, compressed natural gas (CNG) is generating a lot of attention as an alternative fuel. Mazda is promoting technology development to provide both driving pleasure and outstanding environmental performance by using CNG’s characteristics of significantly lower CO2 exhaust emitted when burned and a high octane rating*6 to optimize SKYACTIV-G’s high compression ratio.
*6 In a gasoline engine, a measure of the fuel’s resistance to knocking (knocking noise and vibration caused by abnormal combustion that results from spontaneous ignition of the air/ fuel mixture due to high temperature and pressure in the cylinder)
