There are a few main differences between electric, hybrid, and plug-in hybrid models, despite their similarities. Electric vehicles (EV) don't release any harmful tailpipe emissions and use an electric battery to operate. This type of vehicle is quieter than other hybrid models. Hybrid models rely on both gas and an electric battery to be powered and don't use a lot of fuel, reducing the cost of driving each day. Those who select plug-in hybrid models can drive a vehicle that uses gas and can plug into a standard household electric outlet with the included charging cable.
