The test trucks, internally known as “Gen 2” are the second iteration of trucks jointly developed by the trucking and technology companies. This milestone is one of many along the Daimler-Torc journey to realize their vision of becoming the standard in self-driving trucking and advance their mission of saving lives.
Torc and Daimler Trucks’ ultimate goal is to reinvent the truck by co-developing a Level 4 Freightliner Cascadia which includes safety-critical redundancy components, as well as the seamless integration of additional computes and hardware required for self-driving technology, the companies say.
“To meet the redundancy and performance requirements of a self-driving truck, the traditional truck chassis must be reinvented. Just like any major innovation, it requires a stair-step approach toward the final product. We are taking this one step at a time, with safety as our guiding principle,” says Michael Fleming, Torc CEO.
Torc has been commercializing its self-driving technology in heavy-duty applications for more than a dozen years. Fleming says Torc is directly applying this experience to solve the challenges ahead.
In 2019, Torc and Daimler Trucks created a unique relationship in the trucking industry by combining the pioneer and leader in trucking and a pioneer and leader in self-driving technology. This combination of complementary technologies created the foundation for Torc and Daimler Trucks to bring self-driving trucks to market within the decade, Torc says.

“We knew from the outset that self-driving technology cannot be commercialized without an OEM. In trucking, there are only a handful of OEMs and we were fortunate to join the industry leader,” Fleming says.
The goal: Level 4 integrated truck that provides true customer value
“Our partnership with Torc is critical to our efforts to commercialize a Level 4 highly automated truck,” says Roger Nielsen, DTNA president and CEO. “Torc’s experience with developing self-driving technology and their focus on safety makes them the ideal partner. Our joint goal is a Level 4 integrated truck that provides true customer value.”
Market-ready self-driving trucks must emulate the actions of the most experienced and safe truck drivers. The partners are developing software and hardware that is seamlessly integrated to reliably handle failures of safety-critical vehicle components, such as braking, steering, power distribution, and messaging.
The team’s vision for a Level 4 vehicle platform is one in which component redundancies and software behaviors work together. In the case of a brake failure in a Level 4 truck, redundancies would maintain the vehicle’s ability to decelerate and stop without human intervention. Torc’s self-driving software would then be able to maneuver to a safe location so a support crew could service the brake system, according to Fleming.
Another integral behavior the team is working to replicate is the way experienced truck drivers are able to feel component failures. “Our software engineers are working with highly skilled truck drivers to understand this experience and transition this human intuition into embedded sensors and algorithms,” Fleming says.
Iterative truck generations for development
Torc and DTNA expect to develop multiple iterative test truck models before they release a self-driving truck for commercial customers. The prototypes will incorporate many lessons learned from testing and development since the partners started working together in 2019.
The upgrades included in the “Gen 2” prototype truck are specifically designed to bolster the testing effort and accelerate data collection to assist in machine learning and algorithmic development.
Improvements in data collection and transfer will help the development team expand capabilities quickly and safely, supporting Torc’s effort to scale its test fleet in multiple locations. Additional sensor density and coverage will assist in overall high-fidelity perception performance and long-range sensing power, critical for highway driving.
Both companies have stated that they will only deploy self-driving trucks when they are safe and reliable — not by a set date. Fleming says the team will meet its goal because, “We are two pioneers joining forces and we understand the complexities of commercializing self-driving technology. Our mission is to save lives and our vision is to become the standard in self-driving trucking.”
