Tailor-made bus and trucks solutions
Dana TM4 can supply both traction and auxiliary solutions optimized for medium-and heavy-duty electric and hybrid vehicles such as:
- 6-18 meter buses
- Delivery trucks
- Municipal fleet work trucks
- Shuttles and more
System supplier
To be a system supplier doesn’t only mean supplying motors and controllers, but supplying the system that optimize the application in terms of efficiency, performance and cost. The Dana TM4 Sales and Application Engineering team works in close partnership customers to develop the vehicle design on all aspects relating to the powertrain. Starting from the target performance of the vehicle, using proprietary software for motion simulation, Dana TM4 is the expert that will help you select the right components of the powertrain and harmonize the overall project.
Direct-drive configuration allows for:
- High efficiency, therefore reducing the need for battery capacity
- Easy integration between the H beam of the truck or in the engine bay of the city bus
- Lower maintenance
- Faster ROI
« With their superior efficiency, performance, competitive price and maintenance-free lifecycle, the TM4 SUMOTM powertrains are enabling our customers to get a faster ROI. »
