Mitsubishi Electric said it would spend JPY4bn (US$33m) at its subsidiary Mitsubishi Electric Automotive America (MEAA) to expand and newly construct facilities to increase production of high efficiency alternators.

The move is the latest step in an ongoing expansion of MEAA’s North American market.

“The US market is expected to enjoy increased vehicle sales, including surging demand for fuel-efficient vehicles in the face of ever-stringent regulations concerning fuel efficiency,” the supplier said in a statement.

MEAA began producing high efficiency alternators at its plant in Mason, Ohio, where the company is headquartered, in 2014. The new additions will increase the production capacity for core parts used in these alternators, enabling MEAA to meet growing demand as it continues to expand its North American market.
