What does the $4,000 actually buy?

On the published rows: Euro VI aftertreatment against Euro III, a ZF automatic against an eight-speed manual, front and rear discs against drums, a leaf-and-airbag rear against leaf packs, a 260 L tank against 200 L, electric air conditioning against manual, a named steering gear against an unnamed one, a three-seat right-hand-drive cab against a two-seat left-hand-drive one, and a 5.5 / 10 T axle group against 4.2 / 9 T.

Does the Euro III truck need AdBlue or urea?

No aftertreatment is listed on its sheet: emission reads Euro III with a mechanical-era calibration, so there is no urea tank, dosing module or catalyst to service. The exposure is regulatory — confirm acceptance where the finished machine will be registered.

Which sheet publishes more engine data?

Neither publishes a complete set. The Euro III sheet gives 180 in a column headed kW/PS with no unit applied and 950 N·m with no rpm anchor; the Euro VI sheet gives 228 kW and no torque row at all. Ask both sellers for the certified figures and the torque plateau.

Which one stops better?

The Euro VI truck carries front & rear disc brakes with ABS; the Euro III truck carries front drum + rear drum with ABS. Discs recover from fade faster; drums are the cheaper rebuild and tolerate grit. Both sheets omit an auxiliary brake, so on long descents neither listing spares the linings.

Is the ZF automatic worth the money?

It depends on the duty, not the truck. Multi-drop urban work with a rotating driver pool is where an automatic earns its keep through shift consistency and clutch life; trunk running with a regular driver is where the manual is cheaper to own. Fast cases are iron-housed and widely rebuilt; ZF depth varies by market and is worth checking before ordering.

Which axle group is stronger?

The Euro VI truck's, on paper: 5.5T plus 10T is 15.5 tonnes against the same 18,000 kg gross, a 2.5-tonne shortfall, where the Euro III truck's 4.2T plus 9T sums to 13.2 tonnes, a 4.8-tonne shortfall. On both, the rear drive axle governs once a body is fitted.

Euro III Drums or Euro VI Discs: The Same 18-Tonne Aumark Question, $4,000 Apart

Writer:Alan Chen(Foton Auman dealer)

Two sheets answer the same question — an 18-tonne 4×2 chassis cab — four thousand dollars apart. The Costa Rica listing at $35,500 is Euro III on drums with a manual gearbox and a 200-litre tank. The Northern Cyprus listing at $39,500 is Euro VI on discs with a ZF automatic, rear airbag suspension and a 260-litre tank. Neither sheet is wrong; they are priced for different worries.

What Euro III asks of the buyer

The ISDe245 30 is a 6700 ml six calibrated to Euro III, and its whole commercial character is what it does not carry: no urea tank, no dosing module, no catalyst substrate to poison. Where diesel quality varies between the port and the interior, and where every taller workshop has rebuilt these engines from hand, that absence is worth real money — it removes the failure categories that dominate modern diesel downtime and leaves commodity wear items: filters, linings, belts, injectors.

The ask is regulatory. A Euro III unit will not qualify everywhere, and the sheet's own caution is the correct one: confirm acceptance where the finished machine will be registered before ordering. Nothing in this article asserts any country's rules — the question belongs to the buyer's registration office, in writing.

What Euro VI asks of the buyer

The D6.7EVIE320 buys compliance, and compliance has a supply chain: urea to source, a dosing module that can clog, a catalyst that can be poisoned by bad fuel, and a derate that interrupts a delivery round when any of it misbehaves. The sheet does not publish an emission route, so the aftertreatment architecture itself is a question for the order confirmation. In exchange the buyer gets a stronger axle group — 5.5T and 10T against 4.2T and 9T — which at the same 18,000 kg gross is a 2.5-tonne shortfall rather than a 4.8-tonne one.

The rest of the premium is physical. Discs front and rear recover from fade in minutes where drums need kilometres, and the ZF 8095 steering gear is named on the sheet where the Euro III truck's is not. Against that, drums remain the cheaper rebuild and tolerate grit better, and the rear suspension swaps leaf packs for an airbag arrangement the sheet records as Leaf Spring / Airbag with leaf counts 3, 0 — a rear that rides empty and carries laden, at the price of one more system to maintain.

The gearbox is the quieter decision

Emission tiers get the headlines; the transmission decides the working day. The Euro III truck carries the 8JS118TA-B, an eight-speed manual in the 118 torque class, iron-housed and rebuildable, with visible headroom over the published 950 N·m. On trunk runs with a regular driver it is the right call, and the cheapest to repair. The Euro VI truck carries the ZF9AS1517TO automatic, which buys shift consistency across a driver pool and removes clutch wear from stop-start multi-drop work — worth its keep in city distribution, indifferent on the open road, and a service-network question in markets where ZF depth is thin.

Routing the $4,000

Registration is tightening, or the truck will be resold in a market that reads certificates — the Euro VI sheet is the defensible purchase, and the site's existing review of it, Euro VI and RHD Worth the Premium?, walks the same arithmetic.

Fuel quality varies and the workshop is a general one — the Euro III sheet keeps the failure categories out of the diary, and its 950 N·m sits in the band a laden box body needs on ramps.

The duty is multi-drop urban with agency drivers — price the automatic before committing, because clutch replacements are the line item a manual gearbox writes into that duty.

The duty is gradient-heavy — note that neither sheet lists an auxiliary brake. The $4,000 buys emission tier, gearbox, discs, airbag and tank size; it does not buy an exhaust brake or a retarder on either listing.

Every figure in this article comes from the two listings' own parameter sheets: the engine rows, the axle and ratio figures, the brake and tyre lines, the tank and suspension rows and the two prices. Where a sheet leaves a row empty — the torque figure on the Euro VI truck, the steering gear and the auxiliary brake on both — the article records the blank rather than filling it, and no country's regulations are asserted anywhere.
