You can enjoy all sorts of fuel savings when you choose an electrified vehicle. Hybrids use a combination of electricity and gas power that enables them to use less fuel. Hybrid technology enables the battery to recharge itself through systems like regenerative braking. Plug-in hybrids are similar, but the key difference is that they boast bigger, more powerful batteries that can give you more of an electric driving range. These batteries must be recharged by plugging your car into a power source. EVs, on the other hand, use pure electric power, and there isn't a place to put gas even if you wanted to.
