The direct-drive advantage

TM4 SUMO high torque motors can interface directly with standard rear differential without the need for an intermediate gearbox.

A direct drive system allows for the following benefits:

  • High reliability: removing the gearbox means removing the most mechanically complex and maintenance intensive part of the vehicle
  • Easy to fit between the H beam of the truck or in the engine bay of the city bus: no need to modify the vehicle architecture
  • Low maintenance: Dana TM4 direct-drive motors require no maintenance
  • Fast ROI
