Freightliner Trucks has introduced the 2014 Cascadia Evolution Class 8 truck model. Powered by Detroit and featuring some of the most advanced aerodynamic enhancements in the industry, the Cascadia Evolution delivers up to an additional 7 percent improvement in fuel economy over an EPA 2010-compliant Cascadia equipped with a first generation aerodynamic package and 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 maximizing our customers' bottom lines with new product advancements that will deliver unprecedented fuel efficiency," Hames added.
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 only full-scale, OEM owned and operated wind tunnel for big rigs in North America. 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.
Achievements in Aerodynamics
With new, standard features that seamlessly combine the Cascadia's already sleek profile with enhanced aerodynamics, 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.
The Cascadia Evolution also includes an improved windshield seal, elliptical-shaped aerodynamic mirrors and an integrated antenna. New wheel covers on the rear tandem axles, chassis side fairings and 20-inch side extenders further contribute to the truck's efficiency.
Cooling 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.
Also standard with the Cascadia Evolution is Freightliner's proprietary Run Smart Predictive Cruise system. This innovative technology 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.
"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 fuel economy performance and overall cost of ownership."
