Alliance partners Renault and Nissan have been among the most vocal proponents of the zero-emission technology, but have struggled to lower costs enough as they developed their electric cars separately.
The Nikkei said Renault and Mitsubishi Motors, which recently came under Nissan's control, will use the same vehicle platform as Nissan's remodeled Leaf electric car expected to go on sale around 2018.
The three companies will share key components such as the motor, inverter and battery, a move that would lower the Leaf's price by about a fifth, the paper said, without citing its sources
Renault and Nissan will build the next Renault Zoe and Leaf electric cars on a new common platform, Arnaud Deboeuf, senior vice president of Renault-Nissan BV, the alliance's strategic management unit, told Automotive News Europe earlier this month.
