ECM (Electric Corner Modules) or In-Wheel Motors technology is more of a revolution rather than an evolution technology. ECM can be a combination of wheel, tyres, motors, brake, steering, suspension, and cooling system. Implementation of ECM eliminates the need of components such as engine, transmission, differentials, cardan shaft. The other advantages include weight reduction by 10%-25% depending on ECM type and fuel savings of 20%-30%
