Volvo Trucks’ model year 2016 VN series heavy-duty highway tractors will deliver greater fuel savings than previous generation models through an assortment of aerodynamic and powertrain enhancements. Further sculpting of airflow around the exterior and underneath the hood improves fuel efficiency by up to 3.5%. Volvo’s new XE-Adaptive Gearing and Torque Management options can provide fuel efficiency improvements of more than 2.5%.
Aerodynamic enhancements. Enhancements to the bumper, chassis and roof fairings of model year 2016 VN series highway tractors reduce air turbulence around the vehicle exterior and improve airflow under the truck, around tires and the trailer gap. Reducing turbulence and disruptions in airflow from the tractor to the trailer helps improve fuel efficiency.
Powertrain enhancements: XE-Adaptive Gearing and Torque Management. Building on its XE (eXceptional Efficiency) powertrain packages, Volvo will offer an XE-Adaptive Gearing package to further boost fuel efficiency for operations that go out loaded and return empty or lightly loaded, such as bulk haulers, liquid tankers and flatbed carriers. XE-Adaptive Gearing provides the same benefits for dry van trailers operating under the same conditions.
The system is both a direct and overdrive driveline depending on rear axle load, which the system senses in real-time. When loaded, the transmission locks out the 12th gear and provides the performance and fuel efficiency benefits of direct drive. During unloaded or lightly loaded trips, the driveline operates in overdrive, providing enhanced fuel efficiency and even greater driver comfort.
Customers can select road speed limits for loaded and unloaded portions of the trip, customizing their vehicle speeds to fit operating needs. XE-Adaptive Gearing engine ratings will initially be available for Volvo’s D11 and D13 engines paired with an I-Shift automated manual transmission.
Volvo Trucks is also offering three new torque control features designed to increase fuel efficiency, tire life and decrease driveline stress. The expanded offerings utilize Volvo’s numerous multi-torque engine profiles to provide optimized torque management in multiple operating environments.
