The new 6er will feature the new SkyActiv fuel saving technologies, including the SkyActiv-D Clean diesel engine, the new six-speed automatic transmission, and an engine idle-stop system. It will also be the first Mazda equipped with regenerative braking.The system converts kinetic energy into electricity during braking and stores it in capacitors for use later in powering electrical equipment such as the air conditioning, lighting and audio system.If development proceeds as planned, we should be seeing the production version debut next September at the Paris Motor Show.
