The optimized aerodynamic features on the new Cascadia Evolution were developed using DTNA's wind tunnel - the only full-scale, OEM owned and operated wind tunnel for big rigs in North America.
“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.” “The Cascadia and the DD15 have since made a powerful impression on businesses. “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 DTNA. Powered by a Detroit engine and featuring some of the most advanced aerodynamic enhancements in the industry, the Cascadia Evolution delivers up to an additional 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 current model year 2013 Cascadia equipped with the latest aerodynamic upgrades. Freightliner Trucks will start production on the Cascadia Evolution in 2013. Again, the gross combination weight was 76,000 pounds.Ī significant number of test units are already in service with fleets. The Cascadia Evolution achieved 9.31 miles per gallon even while encountering significant cross-winds during the trip. That was followed by the Evolution of Efficiency cross-country tour, which ran 2,400 miles from San Diego, California, to Gastonia, North Carolina. Fuel consumption and distance traveled were measured at the end of the demonstration by Automotive Testing and Development Services (ATDS), an independent, third-party auditor using high-accuracy fuel flow meters. Freightliner officials say tank truck carriers running 80,000 pounds are unlikely to reach or exceed the 10-mpg mark. There, the truck traveled the 8.5 mile closed-course track for 1,000 miles nonstop at an average speed of 60 miles per hour, with a gross combination weight of 76,000 pounds, which ismore typical of freight haulers.
The optimally spec'd Cascadia Evolutionwas tested at the Continental Proving Grounds in Uvalde, Texas. Specifically, the Evolution - powered by a newly designed Detroit DD15 engine and featuring enhanced aerodynamic specs - delivered an impressive 10.67 mpg on a test track. The next morning, the truck builder unveiled its new 2014 Cascadia Evolution, which reportedly achieved better than 10mpg in a recent test. It turned out this was no idle speculation for DTNA's chief executive officer. OVER dinner on May 29 with members of the trucking press, Daimler Trucks North America's Martin Daum suggested that a 10-mile-per-gallon Class 8 tractor was well within reach.
