Volvo Trucks has announced aerodynamic and powertrain enhancements for 2016 VN series highway tractors, in a bid to offer better fuel savings over the previous generation models.
The company said that sculpting of airflow around the exterior and underneath the hood enhances fuel efficiency by around 3.5%.
Volvo Trucks said: "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."
Other enhancements include XE-Adaptive Gearing package and three torque control features, which are claimed to improve fuel efficiency by over 2.5% as well as increase tire life and decrease driveline stress.
Volvo Trucks North American Sales & Marketing president Gran Nyberg said: "Our latest enhancements provide a strong complement to the fuel efficiency improvements of up to three percent provided through last year's introduction of Greenhouse Gas (GHG) 2014-certified engines."
