Freightliner Cascadia’s evolution from 2007 to 2025: Aerodynamics to autonomous to electric

NASHVILLE, Tennesee—From its inception as a more aerodynamic, lightweight, and reliable heavy-duty truck, the Freightliner Cascadia has evolved over four generations to become the Class 8 commercial truck market leader.

Since its debut, the Cascadia has improved fuel economy by 35%. Its fifth generation will add to that, Daimler Truck North America engineers said. Along with its integrated technology, Freightliner leaders said the next Cascadia will offer fleets even better total cost of ownership, thanks to better fuel efficiency and safety technology.

Mark Rourke, CEO of Schneider National (No. 6 on the FleetOwner 500: For-Hire), said TCO is a significant part of his fleet’s philosophy, and that has helped Schneider remain loyal to Freightliner.

“We'll look at lots of different technologies and components over time, but we have such a deep and meaningful relationship at that technical level within our organization, so I think there's a comfort to help us be the lowest cost operator as it relates to individual component systems and how we can get better over time and lower our cost to serve,” Rourke told industry media in Detroit in September before a sneak preview of the new Cascadia. “I think that relationship is a real, meaningful differentiator for Freightliner. I think you deserve great credit for that, and listening to your customers allows us to get in early and learn from you and also learn from us and our experience of putting these products to work over here.”

With the fifth generation Cascadia slated for 2025 production, here is a look back at how DTNA has innovated and continued to build on previous models and established and emerging technologies since 2007.

Freightliner Trucks launched the Cascadia, a Class 8 truck that is not only engineered to accommodate EPA ’07 and ’10 engines but also boasts a 3% improvement in fuel economy over previous models and generous driver amenities in a totally redesigned cab.

2007: Freightliner introduces the all-new Cascadia model with the Detroit Diesel DD15 engine platform. The truck succeeds Freightliner’s Class 8 Century Class and Columbia models. The new Cascadia incorporates new aerodynamics, lightweighting, and improved maintenance.

2011: Freightliner announced during the Mid-America Trucking Show that new chassis side fairings and side extenders are being added to the already aerodynamic Cascadia to improve its fuel economy by an additional 1.8%. Freightliner is also offering lightweight options of the Cascadia to lower the total cost of ownership for fleets.

Scheduled to go into production in early 2013 as a 2014 year model, the Cascadia Evolution combines aerodynamic and proprietary drivetrain advances in an integrated package to deliver that efficiency improvement, according to Martin Daum, DTNA president & CEO.

2012: Freightliner launches the Second Generation Cascadia, engineered to increase fuel efficiency. The new version of the Cascadia introduced the Detroit DT12, an automated manual transmission (AMT) that combined the operational ease of an automatic with the efficiency of a manual transmission.

Daimler Truck North America officials said when they unveiled the truck that this new generation of Freightliner Trucks’ over-the-road Cascadia tractor achieves 5% better fuel economy than the previous model and 7% better than the first generation EPA-2010 compliant model.

Andrew Culhane, Torc Robotics’ chief strategy officer, said his company’s software, combined with Daimler Trucks’ hardware, is creating “an overall system that will empower fleets to run a fully enabled self-driving truck, hub-to-hub or within their network. That’s what we’re looking to get out here.”

2019: Daimler Truck acquires a majority stake in Torc Robotics, a U.S.-based vehicle automation pioneer. The following year, Torc announced plans to scale its self-driving truck testing using the latest generation of the Freightliner Cascadia.

According to both companies, their joint goal is to reinvent the truck by co-developing a Level 4 Freightliner Cascadia that includes safety-critical redundancy components and the integration of additional computers and hardware required for self-driving technology.
