Mazda has decided there's simply no reason why hybrid cars and EVs should have all of the regenerative braking fun. Its new system, called i-ELOOP, is aimed at traditional internal combustion vehicles. But, rather than rely on batteries, the company turned to capacitors which can be charged and discharged in just seconds. The electricity generated is then fed to the car's various electronic components after being passed through a converter to step down the voltage to 12v. By alleviating some of the burden to generate power from the engine Mazda claims it can increase fuel efficiency by up to ten percent. You won't have to wait long to see this tech make it into your next ride either, the world's first capacitor-based regenerative braking system should be making its retail debut sometime in 2012.
