Mazda?s Capacitor-Based Regenerative Braking System

It is called 'i-ELOOP' Mazda's 'i-ELOOP' regenerative braking system Mazda released details on a groundbreaking regenerative braking system that uses a super capacitor in leiu of a battery for quick storage. The system, which Mazda calls 'i-ELOOP', will begin to appear in Mazda's vehicles [b]in 2012[/b]. Mazda claims that in real-world driving conditions with frequent acceleration and braking, 'i-ELOOP' improves fuel economy by approximately 10 percent. We know better but there will always be an advantage with regenerative braking rather than throwing it away any time you have to step on the brake.
