While Lotus has never made an electric car itself (at least publicly: Group Lotus’s Lotus Engineering arm regularly conducts secret projects for other car makers), there are a number of electric Lotuses in existence.
Most famous is the Tesla Roadster. The model used to launch Tesla, the Roadster was based on an Elise chassis and given a 200-mile range. Almost 2500 found homes in its four-year production run, which was devised to get Tesla used to making and selling electric cars and introduce its brand to the world on proven underpinnings.
We still await our first test of the most recent Elise-based electric sports car, the Detroit Electric SP:01. The project has been bubbling for several years – it was announced as far back as 2013 – but funding problems have prevented it from making production.
