MAHLE brings e-compressor production to Tennessee

By Michelle Froese | August 28, 2025

German automotive supplier MAHLE announced that it’s bringing the production of e-compressors to America. The Morristown, Tennessee, facility, which has long manufactured steel pistons, will add e-compressors to its portfolio, supporting internal combustion and electrified vehicle (EV) applications. Nearly 50 new employees will be hired as part of the expansion.

E-compressors are central to thermal management in EVs. They regulate cabin climate and, more importantly, control battery pack temperature to protect cell life, maintain high charging speeds, and preserve driving range. By producing these systems domestically, MAHLE aims to supply US automakers with localized components critical to next-generation EV platforms.

The company’s history of success in aluminum piston production for internal combustion engines dates back over a hundred years. MAHLE’s first presence in the US began in 1975 with the establishment of a cylinder manufacturing facility in Fairfield, Connecticut.

In 1978, the Morristown plant became the first greenfield manufacturing facility for MAHLE in North America, today manufacturing steel pistons for all major American light and heavy-duty commercial vehicles, and high-performance aluminum pistons for motorsport.

With the installation of a new production line for e-compressors at the site, employment will increase to almost 800, representing another important step toward shaping the future of mobility. Over the past five years in the state of Tennessee alone, MAHLE created more than 300 new jobs in Murfreesboro to manufacture thermal management products.

The company operates 15 locations across the US with the North American headquarters in Farmington Hills, Michigan. It plans to increase its presence and activities in the USA in the coming years as part of the group’s stragegy to manufacture world class products for vehicles “Made in America”.

“Starting the e-compressor production in Morristown, Tennessee, marks an important milestone for MAHLE as we further strengthen our footprint in the USA and our role as local employer,” said Arnd Franz, chairman of the Management Board and CEO of MAHLE.
