Freightliner Supertruck II is the Most Aerodynamic Truck Ever
How can you get off to a good start as a truck and still do more justice to environmental concerns? The "Freightliner SuperTruck II" concept vehicle presented by Daimler Truck North America (DTNA) this week in Las Vegas shows that this is possible. The heavy truck was developed as part of the SuperTruck program co-financed by the US Department of Energy with the aim of reducing pollutant emissions from road freight transport....
Freightliner SuperTruck II

When developing the Freightliner SuperTruck II, the main focus of Daimler Truck North America was to improve the operational efficiency of the truck and ultimately increase the vehicle's economy. In order to achieve this goal, the Daimler truck engineers' to-do list included: improved aerodynamics for the tractor unit, an improvement in the drive train, tires with low rolling resistance and optimized energy management.

The work of Freightliner engineers has paid off, as the aerodynamic improvements are proving so effective that they reduce the SuperTruck II's drag by more than 12 percent compared to the 2015 Freightliner SuperTruck I. The bonnet, bumper and chassis lining were redesigned for this purpose. To further improve the car's aerodynamics, the grille, air intakes and doors were molded as seamlessly and cleanly as possible. Furthermore, active side extensions and a roof spoiler system together with the replacement of the conventional exterior mirrors with a camera system contribute to an improvement in aerodynamics.

The new Freightliner concept truck is equipped with the most efficient powertrain that the Daimler Truck subsidiary has ever installed in a truck. Compared to the SuperTruck I, it saves 5.7 percent fuel. A 48-volt electrical system with lithium-ion batteries helps with the more economical use of diesel. In addition, the SuperTruck II rolls on newly developed tires. The brand new rubbers not only reduce the energy consumption of the truck - thanks to less wear they also reduce maintenance downtime.
