YOKOHAMA, Japan—Nissan Motor Corp. has unveiled a new approach to electrified power train development. Its “X-in-1” initiative features shared, modular components that will reduce manufacturing costs by 30 percent.

Nissan engineers have developed a 3-in-1 power train prototype that modularizes the motor, inverter and reducer. A 5-in-1 prototype, which additionally modularizes the generator and increaser, is also under development for use in future EVs. To cut costs and improve efficiency, all of the components will be produced on the same assembly line.
