MPMA Releases New Information Sheet: Electrified Vehicle Drivetrains

The Motion + Power Manufacturers Alliance (MPMA) announces the release of a new industry guideline addressing the rapidly evolving EV landscape: AGMA 948-A26, Electrified Vehicle Drivetrains. This provides industry guidance on electrified drivetrains for vehicles, including hybrid electric (HEV), battery electric (BEV or EV), or plug-in hybrid electric (PHEV) vehicles, with the prime mover power source or sources as any combination of battery, fueled ignition engine, and/or fuel cell. These can generally be referred to as xEVs.

“I was very pleased with the speed at which the group completed this project.” Stated project leader, John O’Neil of Star SU. “We felt from the start that it was necessary to move quickly as the technology was evolving. It’s always a pleasure to work with a group of dedicated individuals and companies willing to share their time and expertise with the Motion + Power community, especially on this project, as it covered a wide range of subject matter and vehicle types.”

The document addresses new technology in this space. The drivetrains covered include ground and marine applications such as passenger vehicle (car or light truck), heavy duty/commercial, construction, agricultural, mining, tracked, propeller/waterjet, and similar drivetrains.

“Having our first meeting in June 2024 and releasing a 74-page technically reviewed document in June 2026 is unprecedented at MPMA. The dedication of the individuals involved, along with the support of the member companies to sponsor those individuals, was the key ingredient to producing this information sheet in record time,” stated Todd Praneis, VP Technical, MPMA.

We would like to thank the members of the committee for their volunteer work on this document:

MPMA would like to thank the members of the AGMA 948 Working Group for their valuable work in developing the document and the Gear Applications Committee for overseeing the project.
