Renault and Nissan have said increased savings from their carmaking alliance by 6.7% last year, as the first cars built on jointly developed vehicle architectures rolled off production lines, Reuters has reported. Alliance savings rose to €2.87bn ($3.91bn) in 2013 from €2.69bn a year earlier, the alliance said. Alliance executive vice president, Christian Mardrus, said it was targeting €3.5bn of savings this year. Production began at Nissan last year from the alliance’s first jointly developed mid-size car platform, CMF. Renault is due to launch its first CMF-based vehicle next year, a replacement for the ageing Espace minivan.
