Efficiency Run 2016

In collaboration with the trailer manufacturer Krone, Daimler developed an integrated approach to reducing CO₂ emissions as well as reducing fuel consumption in the haulage sector. Daimler is now presenting a wholly optimized Mercedes-Benz Actros as one of the results of this initiative.

It is not just the engine in a vehicle that is responsible for CO2 emissions in the haulage sector. There is a whole set of other leverage points that can contribute towards reducing the environmental burden. For this reason Daimler initiated the "Efficiency Run" field trial in 2015. In collaboration with various partners, Mercedes-Benz Trucks designed an integrated approach to reducing CO2 emissions in the haulage sector.

20 percent lower fuel consumption and CO₂

This year, with the aid of trailer manufacturer Krone, a more efficient version of the Mercedes-Benz Actros has been developed. Fitted with the new OM 471 engine, the Predictive Powertrain Control cruise control function and optimized A-Label low-friction tires, the Actros in combination with the Krone "Profi Liner Efficiency" trailer promises a reduction in fuel consumption and CO2 emissions of up to 20 percent (basis for comparison: 2014).

The new engine, for one, with its 12.8 liter displacement plays its part, with up to six percent lower fuel consumption. Then there is the cruise control function, in combination with the Mercedes PowerShift 3 automated transmission, which facilitates an up to five percent reduction in fuel consumption. And following analysis of the FleetBoard data together with the Krone telematics results, there were consumption reductions of over five percent thanks to optimized aerodynamics. Low-friction tires with optimized rolling resistance characteristics make a further two to four percent saving on emissions possible.

The five test vehicles from the transport companies taking part.

Three months of testing by customers

Over a three-month period, the companies Große-Vehne, Elflein, Rhenus, Seifert and Wiedmann & Winz did some heavy-duty testing of the new concept. The trucks covered a total distance of some 150,000 km and transported engines, steel, paper and wood products across the length and breadth of Germany. The haulage companies taking part used their own Actros tractor units.

But for the first time these companies also deployed the Profi Liner Efficiency semitrailer from Krone.

The Krone side paneling structural system, which can be taken down in just a few hand movements, went down very well with the test drivers. They also had praise for the familiar operability of the lifting and lowering unit. The new Krone side paneling covers the sides including the trailer axles, and improves the Cd value by 5.2 percent. The rear aerofoil contributes a further 6.3 percent. Together with the low-friction tires, these two advantages have a positive effect on the fuel consumption of the Mercedes-Benz Actros.

"Working in partnership has moved us a decisive step forwards in terms of the integrated approach. Last year's Efficiency Run more than confirmed our expectations. We have subsequently further optimized our trailer, particularly with regard to everyday practicality," commented Gero Schulze, Managing Director of the Krone Commercial Vehicle Group. This improved everyday practicality covers the handling, noise emissions, robustness, loading options and operability.

A concept with a future

"We proved with the Efficiency Run in 2015 that the integrated approach works. Now, just one year later, we are putting products that are fit for series production onto the roads," said Dr. Wolfgang Bernhard, Member of the Board of Management for Daimler Trucks & Buses. The trailer will receive its world premiere at IAA Commercial Vehicles 2016. And the package of measures presented will be turned into series-production products available to order in the near future. The new Krone Efficiency equipment will be offered in future for the Mega Liner, Cool Liner and Dry Liner. The additional outlay for the optimized semitrailer is recouped - depending on the type of deployment and mileage covered - within one to two years.
