The City Car rides on a platform developed for a range-extended hybrid powertrain. A 1.2-liter three-cylinder engine powers electric drive motors, which are mated to a single-speed transmission. This means that around town, the Lotus City Car will be able to run solely on battery power, while the gasoline engine can kick on for needed assistance if necessary.
Lotus is planning to build three versions of the City Car; one for Asia, a European version and eventually a sportier model.
