Mazda has revealed new details about their i-ELOOP (Intelligent Energy Loop) regenerative braking system. It is the first system to use a capacitor instead of a battery.

Mazda has revealed new details about their i-ELOOP (Intelligent Energy Loop) regenerative braking system.

Set to debut in the Takeri concept, the system has a "variable voltage alternator, a low-resistance electric double layer capacitor and a DC/DC converter." While that probably made your eyes glaze over, i-ELOOP is the world's first regenerative braking system to use a capacitor. This eliminates the need for a dedicated RBS battery which, in turn, reduces the system's weight.

Mazda estimates the i-ELOOP system will improve fuel efficiency by ten percent and it will be launched sometime next year.
