New 2014 Cascadia Evolution
Engineered for optimal efficiency, the Freightliner Cascadia has included groundbreaking technologies from the very beginning. Now, representing the latest milestone in its continued pursuit of increased fuel economy, Freightliner Trucks has launched the next generation of Cascadia with the 2014 Cascadia Evolution® powered by Detroit™.

The new Class 8 truck is equipped with the latest version of the Detroit DD15® engine and some of the most aerodynamic enhancements in the industry. Significant fuel savings show an additional 7 percent improvement in fuel economy over an EPA 2010-compliant Cascadia equipped with a first generation aerodynamic package. It also shows up to a 5 percent improvement compared to a current model year 2013 Cascadia equipped with the latest aerodynamic upgrades.
“With the introduction of the Cascadia and Detroit DD15 in 2007, our priority was to help customers lower their total cost of ownership through improved fuel efficiency and performance,” said David Hames, General Manager, Marketing and Strategy for Daimler Trucks North America. “The Cascadia and the DD15 have since made a powerful impression on businesses.”
“Now, with the Cascadia Evolution, we are building upon our commitment to maximize our customers’ bottom lines with new product advancements that will deliver unprecedented fuel efficiency,” he added.
Evolution of Efficiency Tour Shows Significant Fuel Economy Improvements
Fuel economy data for the new Cascadia Evolution was compared to that of the current model EPA 10 Cascadia during a one-week “Evolution of Efficiency Tour” which took place last month. Traveling across the United States under real-life conditions, the two heavy-duty tractor-trailers traveled 2,400 miles at an average speed of 62 mph in a real-world analysis of the improvements in fuel efficiency achieved with the Cascadia Evolution.

Monitoring the trucks every step of the way, an engineering crew traveled as part of the tour in a state-of-the-art mobile command center and made sure every move was orchestrated to ensure accurate test conditions. Extreme variations in weather and terrain were encountered giving engineers a realistic impression of the vehicle’s performance. At the end of the tour, fuel economy showed a significant 7 percent improvement over the EPA 10 model. All data was verified by a third party observer to ensure an unbiased testing procedure.
Aerodynamic Enhancements Add to Fuel Efficiency
“We examined every detail to ensure that no stone was left unturned when developing the Cascadia Evolution,” said TJ Reed, Director of Product Marketing for Freightliner Trucks. “The result is a truck that will immediately benefit from fuel economy performance and overall cost of ownership.”
The aerodynamic features on the new Cascadia Evolution were developed using DTNA’s state-of-the-art wind tunnel on Swan Island. In addition, the truck was extensively tested on highways across the United States, and underwent almost three million miles in combined reliability and fuel economy testing.
Pushing the Envelope − the New Detroit DD15
Only available in the Cascadia Evolution, the newly designed Detroit DD15 engine has been engineered for enhanced performance in fuel efficiency. The DD15 features a proprietary asymmetric turbocharger with a next-generation amplified common rail system (ACRS) allowing for the optimal amount of fuel to be delivered at just the right moment. The asymmetric turbocharger is less complex than variable geometry turbos and, because it is proprietary, is optimally matched to the DD15’s EGR system for best real world fuel consumption, resulting in excellent performance. The next-generation ACRS also delivers higher injection pressure for better combustion control and a simplified design for optimal regenerations.

The enhanced DD15 is more than 100 lbs. lighter than its predecessor and includes an improved fuel filter module with two filters that deliver lower maintenance costs with an industry-leading 100,000 mile filter change interval. The engine also features a variable speed water pump that allows for lower impeller speeds, resulting in less parasitic load, improved DDEC electronics for better engine and aftertreatment system management and an optimized piston design for less friction and oil consumption.
Further adding to the overall performance of the Cascadia Evolution, the DD15’s BlueTec emissions technology 1-Box package has been optimized to decrease size, weight and complexity.
“Detroit is once again challenging the norm by exceeding expectations and optimizing performance,” said Brad Williamson, Manager, Engine and Component Marketing for DTNA. “We’re changing the way the industry looks at diesel engines.
Also standard on the Cascadia Evolution, the Detroit Virtual Technician system helps reduce downtime and decrease maintenance costs by providing real-time engine diagnostics. The system enables drivers and fleet managers to quickly and accurately evaluate events, and in many cases while the truck is still being driven. It also minimizes time in the shop by almost eliminating diagnostic time since this is completed by the Detroit customer support center before it even arrives.
“Powered by a Detroit engine and advanced technology, the Cascadia Evolution is a formidable business tool that doesn’t sacrifice power for efficiency,” said Reed.
Leading the Green Evolution
The Cascadia Evolution is Freightliner’s most recent addition to its line-up of fully compliant GHG14 vehicles.
In February of this year, the Environmental Protection Agency (EPA) certified DTNA’s complete portfolio of model year 2013 on-highway, vocational and medium-duty vehicles as fully compliant with the new GHG14 regulations. DTNA is the first and only North American commercial vehicle manufacturer to be certified as GHG14 compliant.
The company’s advancement in green technologies is part of Daimler’s global Shaping Future Transportation initiative which focuses on reducing criteria pollutants, carbon dioxide and fuel consumption through the utilization of clean, efficient drive systems and alternative fuels.
In DTNA’s ongoing commitment to its customers to provide the lowest cost of ownership, we will continue to lead the industry by building the most innovative and fuel efficient vehicles on the road today. Production of the new Cascadia Evolution will begin in 2013.
