Daimler Trucks subsidiary getting $20 million investment to make e-axles for electric commercial trucks.


Portland, Oregon – Daimler Trucks North America (DTNA) subsidiary Detroit (formerly Detroit Diesel) will make the Detroit ePowertrain to power the upcoming Freightliner eCascadia and Freightliner eM2 commercial electric vehicles (EVs). The $20 million investment is part of Daimler Trucks’ global platform strategy to establish a uniform basic architecture for a broad line-up of EVs.

“By utilizing our Detroit ePowertrain to power the Freightliner eCascadia and eM2, we are giving Freightliner buyers the same level of confidence that comes with our conventionally-powered portfolio,” said Richard Howard, senior vice president sales and marketing, on-highway segment, DTNA.

Initially, the Detroit ePowertrain will offer an eAxle design operating at 400V and be offered in two variants suitable for a variety of commercial vehicle applications. The single motor design is rated at 180hp, delivering maximum torque of up to 11,500 lb-ft of torque, while the dual motor design offers up to 360hp and 23,000 lb-ft of torque.

The Detroit ePowertrain will be mated to the choice of three battery offerings for the eCascadia and eM2, including a 210kWh version, a 315kWh version, and a 475kWh version. Battery packs are comprised of arrays of lithium-Ion prismatic cells. In Detroit’s first ePowertrain offerings, the maximum range specifications will exceed 230 miles on a full charge for the medium-duty eM2 and 250 miles for the Class 8 eCascadia tractor.

“The combination of Freightliner and Detroit has been delivering an incredible experience to our valued customers for over four decades,” said Rakesh Aneja, head of eMobility at DTNA. “An integrated ePowertrain from Detroit respects that legacy and moves us into a new era for the industry by improving operational efficiency while simultaneously eliminating tailpipe emissions.”

Initial production of the Detroit ePowertrain is expected to begin in late 2021. The start of production for both Freightliner models begins in 2022.
