Daimler Truck unveils battery electric autonomous Freightliner eCascadia technology demonstrator

Daimler Truck has the clear goal to lead the transformation to sustainable transportation and to address the challenges of tomorrow.

Daimler Truck unveils battery electric autonomous Freightliner eCascadia technology demonstrator
  • Daimler Truck is pursuing a vision of zero emissions and increased road safety by combining the two most promising technologies to deliver on that vision -- battery electric drive and integrated autonomous driving technology -- in one semi-truck for the first time in its history: the autonomous Freightliner eCascadia technology demonstrator.
  • The truck is based on a production battery electric Freightliner eCascadia and is equipped with Torc's autonomous driving software and the latest Level 4 sensor and compute technology.
  • While still a research and advanced engineering project, the autonomous vehicle has the potential to evolve into a modular, scalable platform that is propulsion agnostic for flexible use in different trucking applications.
  • The goal is to offer customers a choice of the right vehicles for their specific business and transportation needs.

Daimler Truck has the clear goal to lead the transformation to sustainable transportation and to address the challenges of tomorrow. The company is pursuing a vision of zero emissions and increased road safety by combining the two most promising technologies to deliver on that vision — battery electric drive and integrated autonomous driving technology — in one semi-truck for the first time in its history: the autonomous Freightliner eCascadia technology demonstrator.

The truck is based on a production battery electric Freightliner eCascadia and is equipped with Torc's autonomous driving software and the latest Level 4 sensor and compute technology. This will eventually enable Level 4 autonomous driving. Torc Robotics is Daimler Truck’s independent subsidiary for autonomous virtual driver technology. While still a research and advanced engineering project, the autonomous vehicle has the potential to evolve into a modular, scalable platform that is propulsion agnostic for flexible use in different trucking applications. The goal is to offer customers a choice of the right vehicles for their specific business and transportation needs. 

“By combining zero-emission and autonomous technologies in one product, we are testing solutions for challenges our customers are likely to face in the future,” said John O'Leary, president and CEO of Daimler Truck North America. “We want to give them choices that allow them to do what they do best: keep the world moving today and well into the future. That takes a lot of foresight, questioning, testing, learning, improving and co-creating with our customers years in advance to ultimately find the right solution. This truck is a great example of the beginning of that development process.”

Joanna Buttler, Head of Global Autonomous Technology Group at Daimler Truck, added: “Together with Torc, we are making significant progress towards introducing autonomous trucks in the U.S. by 2027. While we target autonomous trucks with conventional propulsion technology for this first market launch, we always look further into the future. We will employ an iterative approach to the development, testing and optimization of autonomous-electric technology, while exploring the most promising use cases in collaboration with our fleet customers.”

Technical specifications: Merging the best of both worlds

The industry-leading battery electric Freightliner eCascadia, a proven vehicle base for the autonomous eCascadia technology demonstrator, went into production in 2022 and has now reached 6 million real-world miles in more than 55 fleets in the United States. This zero-emission Class 8 truck is designed to provide optimal productivity for fleets looking to transition to efficient, zero-emission tractors. The battery can be recharged to 80 percent capacity in as little as 90 minutes. Several battery and drive axle options are available, providing a typical range of 155, 220 or 230 miles, depending on the specific configuration. The Freightliner eCascadia is equipped with the proprietary Detroit ePowertrain, which delivers performance, efficiency, and reliability. For added safety on the road, the eCascadia also comes standard with the Detroit Assurance suite of safety systems, including Active Brake Assist 5.

For the first time, the autonomous sensor suite and compute power, currently being tested on the autonomous diesel Cascadia, is packaged to fit the smaller day cab configuration of the battery electric eCascadia. To ensure adequate cooling, Daimler Truck North America’s engineering team developed an advanced prototype air-cooling concept for the compute stack, which is efficiently positioned between the driver and passenger seats. Customized software provides the autonomous system with control interfaces and feedback on vehicle status. The in-house designed sensor bar cover, which incorporates cameras, lidar sensors and radar sensors, improves aerodynamic performance while providing better protection from damage and soiling. Four additional 12-volt batteries provide enough high voltage power to ensure uninterrupted operation and increased efficiency and safety.
