Both trucks are export models of SAGMOTO, the commercial vehicle brand of Shaanxi Fenghan Trading Co., Ltd. in Xi'an, supplied to mining and construction buyers under authorization SQIDACN 28 and SAG-2025-201. The X3s and the X9 are frequently compared by the same procurement officer, yet they serve opposite ends of the haulage spectrum. The X3s is an 8x4 heavy tipper in the 385 to 420 hp class with 13-tonne axles and a 25 to 40 tonne payload envelope. The X9 is a light 4x4 all-wheel-drive tipper with a 160 hp Yuchai YC4E engine and a 4.5 to 25 tonne gross combination window. This comparison weighs site conditions, cycle distance, fuel per tonne, maintenance and price so the right truck reaches the right road.
Two very different haulage tools
The X3s is built for volume and weight. Its 8x4 configuration spreads a heavy payload across four driven or trailing axles, and the Cummins ISME 420 or Weichai WP10 to WP12 engine delivers the low-end torque needed to start a 38-tonne load on a quarry ramp. The chassis, frame and 13-tonne rear axles are engineered for continuous shock loading on hard, prepared haul roads.
The X9 is built for access. Its 4x4 all-wheel-drive layout and lighter 160 hp Yuchai YC4E engine suit unpaved farm tracks, remote dam sites, rural construction and agriculture haulage where a heavy rigid truck would bog down or damage the surface. The 4.5 to 25 tonne GCW window covers small tipper and flatbed duties where the priority is reaching the site, not maximising payload per trip.
Power, driveline and payload class
The table below sets the two platforms side by side on the values that drive the buying decision. Confirm exact figures against the individual vehicle certificate at order.
| Parameter | X3s 8x4 | X9 4x4 |
|---|---|---|
| Configuration | 8x4 heavy tipper | 4x4 light AWD tipper |
| Engine | Cummins ISME / Weichai | Yuchai YC4E |
| Power | 385 to 420 hp | 160 hp |
| Gearbox | Fast 12JSD, 12 speed | 6 speed manual |
| Rear axle | 13 tonne, single-reduction | Light axle, AWD transfer |
| Payload class | 25 to 40 tonnes | 4.5 to 25 tonnes GCW |
| Typical use | Quarry, mine, highway | Rural, agriculture, soft road |
Operators specifying an off-road variant can review the SAGMOTO off-road 4x4 mining trucks line for the all-terrain options, while those focused on rigid dump bodies should also compare the SAGMOTO dump truck models 6x4 8x4 range to confirm the X3s sits correctly in the heavy class. The X9 is the entry point into all-wheel-drive tipping, distinct from the heavier X9s tractor which is a different model entirely.
The driveline gap is the central point. A 420 hp 12-speed truck moving 38 tonnes is a different economic instrument from a 160 hp 6-speed truck moving 8 tonnes across a flooded field access. Comparing them only on sticker price misses the mission fit.
Site conditions and cycle distance
The X3s performs on prepared haul roads with firm subgrade, gentle to moderate grades and cycle distances of 2 to 15 km per leg in pit-to-plant or quarry-to-rail work. Beyond 15 km per leg, its fuel and tyre cost per tonne stays competitive because the payload is large. On soft, steep or unformed roads, the 8x4's length and weight become a liability, increasing stuck risk and surface damage.
The X9 excels where the X3s cannot go: narrow rural bridges, unpaved agricultural tracks, river-crossing approaches and remote dam or solar-site access roads. Its short wheelbase and all-wheel drive keep it moving in mud where a heavy tipper would need a dozer escort. Cycle distances are typically short, under 5 km, with the value being access rather than volume.
Fuel per tonne and operating economics
Fuel per tonne-kilometre is the metric that separates the two. The X3s burns more absolute diesel, roughly 32 to 42 litres per 100 km under load, but spreads that across 25 to 40 tonnes, so the fuel cost per tonne-kilometre is low on prepared roads. At a 38-tonne payload and 40 litres per 100 km, the fuel per tonne-km is about 0.0105 litres, which is efficient for heavy haul.
The X9 burns about 12 to 16 litres per 100 km but carries only 4 to 8 tonnes on a typical rural run, so its fuel per tonne-kilometre is higher in absolute terms. However, on a site the X3s cannot reach at all, the X9's cost is the only available cost, and the alternative of manual or tractor haulage is slower and dearer. The economic comparison is therefore site-dependent, not absolute.
| Metric | X3s 8x4 | X9 4x4 |
|---|---|---|
| Fuel under load | 32 to 42 L/100 km | 12 to 16 L/100 km |
| Typical payload | 25 to 40 tonnes | 4 to 8 tonnes |
| Fuel per tonne-km | Very low on good road | Higher but only option |
| Best cycle | 2 to 15 km leg | Under 5 km leg |
Maintenance cost per kilometre
The X3s carries heavier components with longer service intervals appropriate to high utilisation. Brakes, tyres and driveline parts are larger and cost more per item, but they are consumed across more tonnes moved, so the maintenance cost per tonne carried is contained on a busy site. Astandby X3s used only intermittently will show poor cost per km because the fixed service schedule still runs.
The X9's smaller parts are cheaper per item and its lighter duty means lower per-km wear on a gentle rural run. In mud and water, though, the all-wheel-drive transfer case, hub seals and brake components wear faster, so the maintenance cost per km can climb on a harsh access road. For both trucks, a consolidated starter parts kit shipped by sea with the unit prevents the downtime that a single unavailable seal causes.
Purchase price gap and resale
The X3s sits in the heavy price band, reflecting its 420 hp engine, 13-tonne axles and 8x4 chassis, while the X9 is a light-platform purchase at a fraction of that cost. The price gap is wide enough that a fleet could buy three or four X9 units for the cost of one X3s, which matters for a small operator who needs access trucks more than heavy haul capacity.
Resale follows the duty. In mining and quarry regions the X3s holds value because heavy tippers are always in demand. In agricultural and rural markets the X9's lower entry cost and useful all-wheel-drive capability support a steady used market among smaller contractors. Neither is universally more valuable; each is worth most where its mission fits.
Total cost of ownership over a five-year horizon
The purchase price gap is wide, but total cost of ownership reframes the choice. Model a five-year horizon at 1,800 operating hours per year for the X3s on a busy quarry cycle, against 900 hours per year for the X9 on intermittent rural access. The X3s burns roughly 36 litres per 100 km at a 35-tonne average payload across perhaps 60 km per operating day, so annual diesel is about 115,000 litres, or 190,000 EUR at 1.65 EUR per litre, while moving roughly 189,000 tonnes of material per year. That is about 1.00 EUR of fuel per tonne moved, before labour and tyres.
The X9 at 14 litres per 100 km and a 6-tonne payload across 40 km per day burns about 20,000 litres annually, or 33,000 EUR, moving roughly 16,200 tonnes per year, which is about 2.04 EUR of fuel per tonne. On fuel alone the X3s is twice as efficient per tonne, but only because its road supports the volume. Add maintenance at 0.05 to 0.09 EUR per km for the X3s and 0.04 to 0.07 EUR per km for the X9, plus tyres at 0.06 and 0.04 EUR per km respectively, and the X3s still wins per tonne on a prepared road while the X9 wins on capital deployed and access reach.
Depreciation is the swing factor. The X3s loses more absolute value over five years given its higher base price, yet its resale in mining regions stays strong, so the net cost per tonne remains low where utilisation is high. The X9's lower base price and steady small-contractor demand give a gentle depreciation curve that suits an operator who cannot guarantee 1,800 hours per year. The honest conclusion is that neither truck is cheaper in the abstract; the X3s is the lower cost per tonne on a prepared heavy corridor, and the X9 is the lower risk and lower capital commitment for distributed light haulage where the alternative is no truck at all.
Decision matrix by application
For mining and quarry haulage on prepared roads with 25 to 40 tonne payloads, the X3s is the clear choice on cost per tonne and durability. For rural construction, agriculture haulage, dam and solar-site access, and any duty requiring all-wheel drive on soft or remote roads, the X9 is the rational pick despite its higher fuel per tonne, because it is the only one that reaches the site.
A mixed operation should hold both: X3s units on the main prepared haul and X9 units for feeder access and light satellite work. Specifying the X3s for a soft rural track, or the X9 for a 38-tonne quarry cycle, would be a misallocation that raises cost and risk. Match the truck to the road, not the budget line, and the fleet economics follow.
