Mazda is always working hard to develop environmental technologies which will contribute to an exciting and sustainable future for people, automobiles, and the Earth.
Idling Stop Technology
Idling stop systems save fuel by automatically shutting down the engine when the vehicle is static and restarting it when the vehicle returns to motion. This Technology of Mazda improves fuel economy by approximately eight percent. Mazda’s i-stop restarts the engine through combustion.
This technology enables the system to restart the engine with exactly the same timing every time, to enhance fuel economy, and to deliver smooth and comfortable acceleration for the driver at restart. The restart takes place in a mere 0.35 seconds, which is about half of the time taken by conventional starter-motor idling stop systems.
Brake Energy Regeneration System
Brake energy regeneration systems convert a vehicle’s kinetic energy into electricity as the car decelerates. The electricity is then stored for later use. It can be used to power the headlights, climate control, audio system, or any other electrical equipment. This reduces the need for the engine to burn extra fuel in order to generate electricity, and thereby improves fuel economy.
Mazda undertook development of electric vehicles with the aim of offering all our customers fun-to-drive performance and outstanding environmental and safety performance. The result is the Demio EV which offers both the sporty driving people expect from Mazda and a remarkable driving range of 200 km.
Electric vehicles have batteries and electric motors instead of engines and fuel tanks, and are powered entirely by electricity. The Demio EV features a unique coil-switching motor which delivers both high torque and high RPMs. Another special feature of electric vehicles is the quietude of the cabin due to the complete lack of engine noise.
Mazda’s hydrogen rotary engine use hydrogen as its fuel, emits no CO2 and offers superb environmental performance. A dual-fuel system allows the vehicle to run on either gasoline or hydrogen. The RENESIS hydrogen rotary engine employs direct injection, with an electronically-controlled hydrogen gas injector.
The Premacy Hydrogen RE Hybrid combines Mazda’s hydrogen rotary engine with a hybrid system for significantly improved performance and practicality. The engine’s reduced intake/exhaust resistance and improved combustion efficiency yields high power output across a wide range of engine speeds.
Bio-based Engineering Plastic
Bio-based Engineering Plastic that can reduce its impact on the environment featuring high-quality finish made from plant derived materials. Mazda has succeeded in developing the automotive industry’s first high-strength heat-resistant plant-derived bioplastic for auto interior parts, and the world’s first biofabric for vehicle seat upholstery made entirely from plant-derived fiber.
This bio-based engineering plastic is used for the first time for interior parts for the all-new Mazda MX-5 was launched globally in 2015. Moving forward, it will be used for exterior parts in other production models due to the outstanding durability.
