METZ, France—For decades, two Stellantis factories here have mass-produced internal combustion engines and transmissions. The facilities will be upgraded to assemble EV motors and transmissions.

The Trémery plant, formerly the world’s largest diesel engine factory, will become the first Stellantis’ facility to mass-produce electric motors. Through a joint venture with Nidec Leroy-Somer Holding, the plant is expected to assemble more than 1 million e-motors annually by 2024. Assemblers at a “sister” plant in Metz will focus on producing future generations of electrified dual-clutch transmissions.

“Trémery-Metz is a prime example of how we are executing our manufacturing transformation, both in France, and across our global operations,” says Carlos Tavares, CEO of Stellantis. “We have now created a new global value chain with trusted partners, including five gigafactories, to support our global EV battery strategy and propel our Dare Forward 2030 targets.

“As Stellantis continues investing in its electric future, [our] transformation is being carried out in [conjunction] with unions and social partners in France to ensure the sustainability of manufacturing operations,” adds Tavares. “[We] support employees along this journey through ongoing training and upskilling programs and activities.”
