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 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. "The result is a truck that will immediately benefit fuel economy performance and overall cost of ownership."Īvailable only in the Cascadia Evolution, the newly designed DD15 engine features a proprietary asymmetric turbocharger with a next-generation amplified common rail system (ACRS).
"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. Now standard with the Cascadia Evolution is Freightliner's proprietary Run Smart Predictive Cruise system, which evaluates the road profile more than one mile in advance, determines the most efficient vehicle speed, and then adjusts the actual speed of the truck for maximum fuel efficiency. New wheel covers on the rear tandem axles, chassis side fairings and 20-inch side extenders further contribute to the truck's efficiency.Ĭooling enhancements include a 1,400 square-inch radiator, which features a revised baffling system and new radiator mounting design that contribute to improved cooling capacity and increased durability. Additional design enhancements includes an improved windshield seal, elliptical-shaped aerodynamic mirrors and an integrated antenna. The Cascadia Evolution incorporates several frontal area updates designed to improve airflow and aerodynamics including a new air dam, bumper closure and a hood-to-bumper fill. In addition, the truck was extensively tested on highways throughout the United States, and underwent almost three million miles in combined reliability and fuel economy testing.įreightliner will begin production of the Cascadia Evolution in 2013.
The optimized aerodynamic features on the new Cascadia Evolution were developed using Daimler Trucks North America's proprietary, state-of-the-art wind tunnel.
The Evolution is the most recent addition to Freightliner's line-up of fully compliant GHG14 vehicles.Ĭascadia Evolution achieved 9.31 mpg on a 2,400-mile cross country trip on real Interstate highways between San Diego, Calif., and Gastonia, NC.,įreightliner says the Cascadia Evolution delivers up to a 7% improvement in fuel economy over an EPA 2010-compliant Cascadia equipped with a first generation aerodynamic package, and up to a 5% improvement compared to a MY 2013 Cascadia equipped with the latest aerodynamic upgrades. Freightliner Trucks has introduced the 2014 Cascadia Evolution powered by Detroit and featuring some of the most advanced aerodynamic enhancements in the industry.
