Workhorse orders 500 more electric powertrain systems from TM4

Workhorse Electric Truck E-GEN 3

Powertrain provider TM4, a subsidiary of Hydro-Québec, has received a new purchase order from Workhorse Group (NASDAQ: WKHS) for 500 SUMO MD powertrain systems, following last year’s order of 150 systems. Workhorse will install the powertrains in its E-GEN and E-100 delivery trucks, destined for such customers as UPS and FedEx Express.

The Workhorse E-100 all-electric truck achieves fuel efficiency of 37.5 MPGe, and has an average range of 100 miles, depending on duty cycle. The Workhorse E-GEN plug-in hybrid step van offers 30 MPGe, and has an electric range of 60 miles, plus an additional 60 miles using the integrated BMW range extender. Both vehicles use Panasonic battery packs, and incorporate Workhorse’s proprietary chassis design, powertrain, battery management system and real-time Metron telematics system.

TM4’s SUMO systems are optimized for medium- and heavy-duty electric and hybrid vehicles such as buses, delivery trucks, shuttles and tow tractors. SUMO’s direct-drive operation is designed to reduce the powertrain’s complexity and cost. Some systems are offered with a double-ended shaft option, which allows for easy integration into many hybrid-electric powertrain architectures.

“TM4’s SUMO powertrain systems have demonstrated excellent performance, efficiency and reliability in our vehicles on the road,” said Steve Burns, CEO of Workhorse Group. “Our partnership with TM4, a world-class Tier 1 supplier, along with Panasonic and BMW, enables us to produce a reliable, cost-effective solution for fleets at scale.”

    What? Workhorse outsources most critical component from 3rd party?

      Why reinvent the motor when there are already many manufacturers?

        To get more margin dollars out of the car, they ain’t gonna get if they outsource critical components like motors from 3rd parties.

          Because designing and manufacturing an efficient, reliable motor is a non-trivial task. To do so cost – effectively with low volume manufacturing is extremely daunting. A company could burn through a series of funding to get a motor manufacturing line up and running. For a startup, it makes much more sense to focus on the total vehicle and use a motor system with known reliability. Later, if they are still in business, they can look at bringing them motor in-house.

            I quite much agreed!
