First regenerative braking system of Mazda

A revolutionary new regenerative braking system has now emerged as the next phase of Mazda’s ‘building block’ strategy to reduce the fuel consumption of its new model fleet between 2008 and 2015.
The unique fuel-saving technology harnesses energy that is otherwise lost as heat during braking, but unlike similar brake energy recuperation systems, Mazda’s solution is a world-first capacitor-based regenerative braking system.
Mazda says its ground-breaking ‘i-ELOOP’ is the world’s first passenger vehicle regenerative braking system to employ a capacitor - an electrical component that temporarily stores large volumes of electricity.
I-ELOOP is claimed that can reduce real-world fuel consumption by about 10 per cent in stop-start driving conditions, meaning it will have a greater contribution to efficiency than Mazda’s i-stop idle-stop function, because compared to batteries capacitors can be charged and discharged rapidly and are resistant to deterioration through prolonged use.
