Customer orders for Freightliner Trucks’ 2014 Cascadia Evolution model topped the 10,000 mark recently, signaling an appreciation by heavy-duty truck customers for a vehicle that features the latest in aerodynamic technology and a fuel consumption of 10.57 miles per gallon.
Freightliner went to great lengths to squeeze economy into every drop of fuel used, and that included installing a Detroit DT12 automated manual transmission with wide-base tires, a 6-by-2-drivetrain configuration and state-of-the-art aerodynamic trailer enhancements. The DT12 transmission complements the Detroit engines and axles with features that impact the vehicle’s overall efficiency and performance in a good way.
Originally introduced in 2012, the new Cascadia Evolution truck is now in full production, providing fuel-saving improvements that deliver up to an additional 7 percent fuel savings over a similar EPA 2010-compliant truck. It also scores an up to 5 percent improvement in fuel efficiency over the 2013 model when you factor in the first-generation aerodynamic enhancements.
Speaking of fuel savings, the Cascadia Evolution is the only Freightliner Class 8 truck to offer the newly designed Detroit DD15 engine. This engine is highlighted by a proprietary asymmetric turbocharger with a next-generation amplified common rail system (ACRS) that enables the right amount of fuel to be delivered at the right time.
Less complex than variable geometry turbos — and because it is proprietary — this asymmetric turbocharger is perfectly matched to the engine’s EGR system for best real-world fuel consumption. The new rail system delivers higher injection pressure for better combustion control and a simplified design for optimal regenerations.
In addition, this enhanced engine is actually more than 100 pounds lighter than its predecessor, and it offers an improved fuel filter module with two filters that deliver lower maintenance costs with a 100,000-mile filter change interval. The engine also features a variable-speed water pump. This allows for lower impeller speeds, improved DDEC electronics for better engine and aftertreatment system management, and an improved piston design for less friction and oil consumption.
Another standard feature of the 2013 Cascadia Evolution is the Detroit Virtual Technician system, which 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 — often while the truck is moving on the road. This tech system almost eliminates diagnostic time in the shop since this is completed by the Detroit customer support center before the vehicle even pulls into the parking lot.
