Like all other manufacturers, Lotus also are targeted to hybrid vehicles. The Lotus Range Extender engine offers the advantage of a cost effective design, high efficiency and low mass and in the same time extended range.
The main project is called "Limo-green" and it is a collaboration between Lotus Engineering, Jaguar Cars Ltd, MIRA Ltd and Caparo Vehicle Technologies. The goal is making a large executive saloon with less than 120 g/km CO2 emissions.
