Mercedes-EQ models are fitted with intelligent technology to make your driving experience as enjoyable as possible whilst efficiently maximising your electric range. Electric cars operate using an electric motor instead of an internal combustion engine. You may have heard of the term BEV, which stands for a Battery Electric Vehicle, or EV which stands for Electric Vehicle. Differently to petrol or diesel cars, electric cars need to be plugged in to a source of electricity in order to run, which you can do at home, at work or at a public charging station.
