Renault-Nissan's electric vehicle investments already exceed $5.6 billion

Renault-Nissan chief executive officer Carlos Ghosn says his companies have invested a combined four billion euros ($5.6 billion U.S. at the current exchange rate) into electric vehicle technology – with even more electric tech spending to come. As Ghosn told Dow Jones Newswires on the sidelines of a meeting organized by the French industry minister, "We have already invested euro 4 billion, and we will be above that as we have development still to do."

Ghosn's goal is to have Renault-Nissan become the worldwide leaders in the electric vehicle segment and the bullish Ghosn says the Alliance is still sticking to its projection that electric vehicles will represent 10 percent of global automobile sales by 2020. That figure has been considered too high by some industry analysts, but Ghosn remains, as ever, bullishly optimistic.
