You're probably familiar with the idea of regenerative breaking when it comes to hybrid models, right? Well, Mazda has decided to take it a step further and put it into some of the new Mazda models being released in 2012. Each model that features this technology, which Mazda is calling i-ELOOP, will be at least 10 percent more efficient than cars not equipped with this technology.

i-ELOOP, which stands for Intelligent Energy Loop, uses a variable voltage alternator, a low-resistance capacitor, and a DC/DC converter to store a vehicle's kinetic energy as electricity. The system taps into that energy to power electric automotive components like audio system and climate control features. Unlike hybrids, which use the energy to help power the large electric motors, this energy is fed directly back into the car.

More specifically, the alternator generates electricity at 25V before it is sent to the capacitor and DC/DC converter. Once there, the convertor drops the voltage down to 12V before it is redistributed throughout the vehicle. The capturing and converting process begins as soon as the driver releases the accelerator, and in the long run will work with Mazda's SKYACTIV and i-stop technology to make some of the most efficient vehicles available.

As you can see, i-ELOOP is just a minor part of Mazda's overarching goal of using energy in the most intelligent ways possible. And while we can't exactly say which new Mazdas will feature i-ELOOP first, we can tell you that Mazda showed it off at the Tokyo Motor Show in their TAKERI concept. We can also tell you that when you stop in and see us at Airport Twin City Mazda, 3076 Airport Highway Alcoa, TN 37701, you'll find some of the most fuel-efficient vehicles available today.
