Mercedes-Benz Aero Trailer Concept
Mercedes-Benz has come up with a concept trailer design that will improve the aerodynamics and fuel efficiency of these big haulers. Dubbed as the Aero trailer, this is the flagship of the automaker’s “Truck and Trailer 7plus” initiative and will be showcased at the first installment of the “Trailer 2011″ show taking place between 25 and 29 November in Kortrijk, Belgium.
The “Truck and Trailer 7plus” initiative has been launched by Mercedes-Benz to cut the fuel consumption and CO2 emissions of the semi-trailer tractors. The basis of this initiative is the newly launched Mercedes-Benz Actros, which consumes seven percent less fuel than its predecessor, which itself was recognized as frugal. Extensive wind tunnel tests have been conducted by the automaker to increase the overall aerodynamics of these trailers.
The Aero trailer features many reengineered components. To improve the aerodynamics and reduce the wind resistance, the automaker has fitted the trailer unit with a front air-dam to reduce the distance to the tractor unit. Other aerodynamics improvements include lateral panels, a rear diffuser and a special design for the rear end. The result of these improvements is an eighteen percent reduction in the wind resistance, which in turn, improves the fuel economy by five percent.
The automaker has estimated that a truck that has an average annual mileage of 150,000 kilometers (93,205 miles) will consume 2000 liters of diesel (528 gallons) less than current models and will also have lowercarbon dioxide emissions, which is estimated to be nearly five ton.
However, for the same cargo bay dimensions, these improvements will increase the length of the trailer to half-meter past the maximum length allowed by the current legislation. But the automaker is confident that this rule will be modified accordingly to make way for these environment friendly trailers.
