Though we're probably biased towards the BYD F6 Hybrid after our indoors test drive, we're genuinely intrigued by the technology. As opposed to a Lithium Ion or NIckel-Metal Hydride battery, this hybrid features a ferrous (iron) oxide battery. The claim is that this will allow a faster charge and a less toxic battery. BYD produces few cars relative to other manufacturers, but they're one of the biggest cellphone battery manufacturers in the world, meaning they know the technology.
