Summary

Currently, the impact of carbon dioxide emissions is one of the most hotly debated questions in the world of cars. This subject has given rise to complex research, and resulted in solutions which have often been expensive for clients. It was in this context that Michelin's 2007 Challenge Bibendum produced a surprising result : a diesel-powered Logan, to which a number of small improvements had been made without any important technological innovation. It found itself on the winner's podium beating prototypes which were much more sophisticated. Its environmental performance and the modest cost of the vehicle justify its name, the Eco2. It is both ecological and economical. This success was the result of work carried out by the new department created within Renault's Research Division, the DiSA (Direction de la synthèse automobile), and made possible by a philosophy of 'concept-driven' innovation.
