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." The Detroit Difference Available only in the Cascadia Evolution, the newly designed DD15 engine features a proprietary asymmetric turbocharger with a next-generation amplified common rail system (ACRS). 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, Daimler Trucks North America. "We're changing the way the industry looks at diesel engines." The Detroit Virtual Technician system – standard on the Cascadia Evolution – helps reduce downtime and decrease maintenance costs by providing real-time engine diagnostics, enabling drivers and fleet managers to quickly and accurately evaluate events, and in many cases allowing them to remain driving when others would have to stop to evaluate the event. It also minimizes time in the shop by almost eliminating the diagnostic time since it is completed when the truck arrives by the Detroit customer support center. "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.
