Renault-Nissan CEO Carlos Ghosn remains adamant to form an alliance with an American carmaker a year after talks with GM fell though and no progress made with either Chrysler or Ford. Speaking at a conference in Tokyo Ghosn said that if he had the opportunity to obtain a new partner he would and referred to the success of the partnership between Renault and Nissan as indication of the possible of benefits.

Ghosn explained that the Renault-Nissan alliance is “the only automotive alliance which works.” He added, “when something works, you have a tendency to want to expand it.” Renault-Nissan’s combined sales are expected to total about six million units this year, according to Automotive News, and this figure is expected to rise to between seven or eight million units within the next two years.

Some of the synergies formed from the original alliance between Renault and Nissan included shared engineering and manufacturing resources as well as some sales operations and information technology assets.
