The eLion is the result of a collaboration between four compagnies from Quebec:  Dana TM4 on supplying the motor, CNTA on developing the electric drivetrain, B3CG on providing the battery packs and Bus Lion. It is the first electric school bus of Type C to be produced in America.

Prestolite E-Propulsion System (PEPS), TM4's Chinese joint venture with Prestolite Electric Beijing Ltd (PEBL), has successfully completed commissioning of multiple electric bus prototypes powered by  TM4 licensed technologies in China.
