In addition to the weight savings, the New Final Drive (NFD) particularly benefits from the actively controlled oil regulation in the final drive, the heart of the axle. This technology and type of construction is without parallel worldwide: the lubricating oil is supplied as needed depending on the speed, torque and temperature. Intelligent oil management minimises the swirl of liquid in the final drive and thus reduces the friction loss from the gears turning in the oil bath. The New Final Drive axle completes the second generation of the Integrated Powertrain from Daimler Trucks and results in fuel savings of up to 6.5 percent for the Mercedes-Benz Actros compared with its predecessor.

"The second generation of the Integrated Powertrain from Daimler Trucks – consisting of engine, transmission and axle – has already resulted in fuel savings of up to 6 percent for the Mercedes-Benz Actros and ensures the lowest possible Total Cost of Ownership. The world's first intelligent truck axles even enable us to reduce fuel consumption by a further 0.5 percent. This once again demonstrates our technology leadership and directly pays off for our customers."

Frank Reintjes, Head of Global Powertrain and Manufacturing Engineering Trucks

In June 2017 the production of the axle started in the Mercedes-Benz plant Kassel. Besides the German location also the Detroit Diesel Corporation produces the connecting element.
