The Mercedes-Benz Actros 2645, particularly in its Euro 5 configuration, is recognized for its fuel efficiency and is considered among the most fuel-efficient trucks in many fleets[7].
While official published average fuel consumption figures specifically for the Actros 2645 variant are not broadly listed, related Actros models such as the 1845 LS typically average around 26.5 liters per 100 kilometers under typical driving conditions according to large-scale European fuel consumption comparison tests[1]. In similarly configured productivity tests, the broader Actros platform (which shares engines and technology with the 2645) recorded an average fuel consumption of 51.28 liters per 100 km, though this figure was likely under test conditions with heavy payloads and demanding routes[3]. It is important to note that real-world consumption depends greatly on load, terrain, driving style, and operational conditions.
Fleet operators and recent buyers, such as Engen in South Africa, highlight the 2645FS Euro 5’s outstanding fuel efficiency, which they describe as the best in their fleet[7]. This is aided by advanced engine technology and digital management systems such as Fleetboard, which promote economical driving habits and efficient operation.
For reference, the Actros 2645 is equipped with a 12.8-liter OM460 inline-6 engine delivering approximately 330 kW (449 hp) and 2200 Nm of torque[6][8]. Fuel tank capacity is typically around 400 liters[2].
