A new roof fairing is now available for Western Star 5700XE 82-in. ultra-high roof sleeper models. The roof fairing maximizes aerodynamics for the largest sleeper available from Western Star, providing superior fuel efficiency without sacrificing comfort and space.
Designed and tested in the Daimler Trucks North America (DTNA) proprietary, state-of-the-art wind tunnel, the roof fairing optimizes airflow across the trailer gap and sides to reduce drag.
The new roof fairing has been designated as SmartWay Certified by the EPA. SmartWay is a voluntary program for the transportation industry that is comprised of companies committed to reducing emissions and eliminating waste. Several 5700XE configurations with full aerodynamics packages are already SmartWay certified.
“We’re proud of our participation in the SmartWay program and are dedicated to providing new solutions that benefit both our customers’ bottom lines and the environment,” says Samantha Parlier, Vice President, Marketing and Product Strategy for Western Star Trucks. “Western Star Trucks and DTNA are deeply committed to manufacturing products that improve freight efficiency and reduce fuel consumption.”
The 5700XE was designed with efficiency as a priority with standard features such as an aerodynamic hood, roof, chassis and cab fairings that reduce drag. And, when spec’d with Detroit powertrain components – such as Detroit engines, the Detroit DT12 automated manual transmission and Detroit axles – the 5700XE delivers the performance and efficiency customers demand.
