Western brands (Caterpillar 770, Komatsu HD325): 36–42 litres per 100km (fully loaded combined cycle)
Chinese brands (XCMG, Sany, Shaanxi wide-body mining trucks): 32–37 litres per 100km (fully loaded combined cycle)
Gap per 100km: Chinese trucks burn 3–6 litres less diesel, cutting fuel costs by 8%–14%
Western brands (Caterpillar 785, Komatsu 980E): 470–530 litres per 100km
Chinese brands (Sany SET130, XCMG 1319): 430–480 litres per 100km
Gap per 100km: Chinese trucks save 40–60 litres per 100km, reducing fuel use by 9%–12%On-site comparison at Ghana manganese mines: same 150-tonne class Caterpillar trucks consume roughly 14% more fuel annually per unit.
Western brands (Caterpillar 797F, Komatsu 980E-5): 2,700–2,900 litres per 100km
Chinese 360-tonne diesel trucks (XCMG & Sany): 2,480–2,650 litres per 100km
Gap per 100km: Chinese trucks cut fuel burn by 220–280 litres per 100km, an 8%–10% fuel saving.
Engine tuning optimised for short, steep African mine haulsChinese Weichai & Yuchai engines deliver high torque at low RPM. For frequent hill climbs and stop-start mine cycles, they avoid high engine revs that waste fuel. Western Caterpillar C-series and Cummins QSK engines are calibrated for long, flat high-speed routes; they run at constant high RPM in short mine loops and use extra diesel.
Lightweight full-vehicle designChinese frames and dump bodies use optimised lightweight steel, making the empty truck 5%–8% lighter than equivalent Western models. Lower total vehicle weight for the same payload cuts rolling resistance and fuel burn.
Transmission gear ratios built for low-speed mine slopesChinese gearboxes are calibrated for the 3%–7% gradient slopes common across African mines. Western original transmissions are engineered for global highway use, creating higher power loss during slow hill climbing.
Tropical high-temperature cooling calibration for AfricaAll export Chinese trucks come factory-fitted with oversized radiators and constant-temperature electronic engine control. In hot tropical weather, the engine does not inject extra fuel to compensate for heat. Standard Western trucks automatically increase fuel injection to offset performance loss in extreme heat.
Long, gentle haul roads (gradient below 2%, one-way distance over 3km)Western electronic transmissions and zero-fuel coast retarders gain an advantage. The fuel gap shrinks to only 2–4 litres per 100km, a 3%–5% saving for Chinese trucks.
Short, steep frequent cycles (gradient 5%–9%, one-way under 1km — the most common mine layout across Africa)Chinese low-RPM high-torque engines perform best here: Chinese trucks save 8%–15% total fuel.
Rough, broken gravel haul roadsHeavier Western chassis create higher tyre rolling resistance, widening the fuel consumption gap further.
For the majority of African open-pit mines with short, steep haul routes (90% of African mine sites):Same-tonnage Chinese diesel mining trucks use 3 to 280 litres less diesel per 100km, delivering an overall fuel saving of 8%–15%. Smaller tonnage trucks show a smaller absolute litre gap but a larger percentage fuel saving.
For long-distance flat haulage operations: The fuel efficiency gap narrows to just 3%–5%.
Chinese hybrid mining trucks deliver around 20% total fuel savings versus conventional Western diesel trucks.
Choose Chinese trucks to cut short-term daily fuel expenditure.
Choose Western trucks for mine projects requiring over 10 years of continuous service and extra-long transport corridors.
