In an interview, Ghosn said the upward trend will be supported by the two companies' plans to introduce a range of EVs. The Renault-Nissan alliance will have annual capacity to build 500,000 EVs by 2012.
When that level will be reached, the electric product lineup of the two carmakers will be profitable, Ghosn said. "This may happen within the next three years," he told Bloomberg.
Ghosn believes plug-in EVs could represent 10 percent of global car sales in 10 years. Nissan will shortly introduce its first battery-powered car, the Leaf.
