Abstract
Based on the technology development long-term vision, "Sustainable Zoom-Zoom", Mazda has beenpromoting what we call a "Building Block Strategy". With new-generation technology called"SKYACTIV TECHNOLOGY", we thoroughly improve the base technologies for Powertrain efficiency,vehicle weight reduction while combining them with electric device technology in a phased manner soas to reduce C02 emission. In the second step of this approach, we have developed a new regenerativebraking system "i-ELOOP" that recovers energy generated by deceleration and reuses it as electricenergy necessary for a vehicle. Today, I present "i-ELOOP": the regenerative braking technology wedeveloped in the second step of our Building Block Strategy
