e-HDi micro-hybrid technology

They have a reversible starter-alternator that works in tandem with an e-booster to provide a seamless Stop & Start function. Going further than other similar systems, the e-HDi’s Stop & Start puts the engine into idle mode while decelerating before coming to a complete standstill. This reduces consumption by 15% in urban driving by transforming the kinetic energy produced by deceleration into electrical energy.
