NAPA, CA — Since Freightliner started producing the Cascadia Evolution in 2013, the Daimler-owned OEM has taken more than 15,000 orders for the model, a fact that proves carriers are very keen to invest in anything that “dramatically reduces overall total cost of ownership,” Freightliner told an assembly of the trucking press here Tuesday.

Powered by the Detroit DD15 engine, Freightliner claims the Evolution features aerodynamic and efficiency improvements that deliver up to an additional seven-percent improvement in fuel economy over an EPA 2010-compliant Cascadia, and up to five-percent improvement in fuel efficiency over the 2013 Cascadia with first-generation aerodynamic enhancements.

The new 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 rig 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.

The standard-equipment Detroit Virtual Technician system reduce downtime and decreases maintenance costs by providing real-time engine diagnostics and it also minimizes diagnostic time.
