Although specific fuel consumption data for tractor trailers is not explicitly listed on the website, our portfolio of heavy-duty tractors (such as Dongfeng and Chenglong models) enables informed estimations based on powertrain specifications. Tractors equipped with 11–13L diesel engines (380–520 hp) typically achieve a fuel economy of 32–38 L/100 km under standard long-haul conditions (50-ton payload, highway speeds). This efficiency is enhanced by advanced technologies like common rail injection, turbocharging with intercooling, and aerodynamic designs (cab fairings and underbody skirts) that reduce drag by 18%. For long-haul applications, optional auxiliary fuel tanks (150L) extend the operational range to 1,200 km, while electronic engine management systems optimize fuel delivery based on load and terrain. In mixed-traffic urban scenarios, fuel consumption may increase to 42–48 L/100 km due to frequent stops and starts. Electric tractor concepts under evaluation (not yet in stock) are projected to consume 150–180 kWh/100 km, but current inventory focuses on diesel-powered solutions. Contact our sales team for detailed fuel consumption reports tailored to specific tractor models, payloads, and operational environments, including total cost of ownership (TCO) analyses comparing diesel and emerging alternative powertrains.
