Mercedes Benz truck fuel consumption
Mercedes Benz trucks fuel consumption
In addition to the engine’s work output, the transmission system and special auxiliary equipment also contribute to lower fuel consumption. The “Predictive Powertrain Control” (PPC) system in the transmission adapts the driving mode and shifting automation based on the topography (Figure 1). Precise and timely gear shifting, based on GPS data and 3D maps, ensures up to a 5% reduction in fuel consumption. Using satellite-based positioning systems and 3D street maps, PPC recognizes road profiles, inclines, and descents. Based on this data, the system optimizes shifting moments, gear jumps, and speed control parameters. The vehicle’s kinetic energy is utilized to avoid unnecessary acceleration, gear shifting, or braking. PPC recognizes around 350,000 km (95%) of European roads and can be used at speeds ranging from 25 to 90 km/h.
Fuel-saving innovations in Mercedes-Benz Actros trucks
In addition to technologically advanced engines and fuel-saving systems, the truck’s aerodynamic design plays an important role in reducing air resistance. For example, even the standard “MirrorCam” system reduces fuel consumption by up to 1.3% compared to the mirrors of previous models. Thus, the streamlined yet thoughtful design, aerodynamically optimized cab shapes, roof deflectors, and side panels help reduce air resistance and improve fuel efficiency at high speeds.
