Island operations have a habit of exposing trucks that were specified for somewhere else. Roads are steep, stop-start and narrow, the run between towns is short, and anything imported has to be supported with whatever the local workshop has on the shelf. The Foton Aumark S 8.5T 4x2 for Grenada is listed at $23,000 with right-hand drive and Euro IV already built in, a Cummins engine and a ZF gearbox. This is our read of the specification for island duty.

Size and payload: what 8.5 tonnes means in practice

Certified gross vehicle weight is 8,500 kg, with axle ratings of 2.85 tonnes front and 6 tonnes rear. Those axle numbers are worth dwelling on for island work: with only two axles and a steep road network, a body that loads heavily behind the rear axle will reach the 6-tonne rear limit well before it reaches the gross figure. Give your bodybuilder's drawing to the dealer and have the loaded axle split confirmed rather than assuming an even distribution.

The chassis measures 6,934 × 2,136 × 2,290 mm on a 3,800 mm wheelbase with a 2,060 mm body width. That is short, narrow and genuinely manoeuvrable — the right shape for alleys, narrow coastal roads and tight loading zones. Note the sheet publishes a gross weight but no rated payload figure, so usable capacity is whatever remains after your body is fitted. Ask for a weighed kerb figure before you build a rate card.

"No rated payload is published for this chassis. Weigh the finished truck before you promise a customer a load."

Engine, gearbox and the gradient question

The engine is a Foton Cummins ISF3.8s4R154 — 3,760 cc, Euro IV, rated at 115 kW, which is 154 PS, with 500 N·m of torque. Worth flagging: the sales title quotes 125 hp while the specification sheet gives 115 kW / 154 PS, so reconcile that with the dealer before you compare it against anything else on paper. What matters operationally is the 500 N·m and the 4.3 final drive, which keeps the engine in its torque band on steep, stop-start coastal roads while still allowing sensible cruising between towns.

Behind it is a ZF 6S558 gearbox. Six speeds on an 8.5-tonner is a conventional, serviceable choice, and the title specifies it as manual. With a full load on long sustained grades you will be downshifting — that is normal for this class and not a fault. If your running is mostly flat highway rather than island gradients, a taller ratio saves fuel; give the dealer your gradient profile and ask them to check whether an alternative ratio is offered.

Brakes and tyres: the specification worth noticing

Braking is pneumatic with a front disc and rear drum configuration and ABS rated 4S4M — four sensors, four modulators, which is full four-channel control rather than a reduced system. On wet, steep coastal roads that is the safety specification you want, and it is worth confirming with the dealer that 4S4M is what ships rather than a cheaper variant.

Tyres are tubeless L215/75R17.5-14PR-MT, six road wheels plus a spare. On a small island market, tyre size availability is a genuine running-cost issue, so confirm local supply before you standardise a fleet on it. Suspension is leaf spring front and rear at 3 and 8+6 leaves, with a 214 × 65 × 5 mm frame — simple, repairable equipment that a local workshop can work on without diagnostic tooling.

Cab and daily equipment

The cab is a regular cab seating three, in right-hand drive. Standard configuration covers a heating and cooling integrated electric air conditioner, an MP3 player, and central locking with electric power windows and remote control. Electric air conditioning rather than a manually controlled system is worth having in a tropical climate, and remote central locking is the sort of item that pays for itself on multi-driver fleets.

Fuel capacity is 120 litres, which is modest — fine for inter-town island running but worth checking against your longest daily loop if you also drive a refrigeration compressor. The frame and leaf suspension are conventional, so body mounting should be straightforward for a local builder.

Cold chain: building it as a reefer

Cold chain transport is one of the two listed applications, and it ships as a chassis at 6,934 mm overall on a 3,800 mm wheelbase, so a reefer body can be built locally in Grenada or pre-fitted before shipment. Budget the box and refrigeration unit against the 8,500 kg gross: insulation and a nose-mounted unit eat into payload, so size the body with your builder before you commit to a specification.

The 115 kW ISF3.8 with 500 N·m has reserve for a body-driven compressor, though an independent diesel reefer unit is simpler to service — particularly on an island where a refrigeration specialist may be easier to find than a mechanic willing to work on a truck-driven system. Confirm compressor drive and alternator capacity with your bodybuilder either way.

Price, and what is not included

The listed $23,000 covers the chassis-cab as specified, with right-hand drive and Euro IV already built in — which is the point worth emphasising, because on many export chassis those are costed as extras. Bodywork, freight, insurance and destination charges are quoted separately. Share your discharge port and body requirement with the dealer and get a landed figure; the chassis number alone is not a budget.

"Changes to cab, tyre brand, axle ratio or emission level all move the price. Settle the full specification before asking for a firm offer."

Two more checks. First, confirm that Euro IV is the standard your registration authority accepts for new commercial registrations — do that before ordering, not after the ship sails. Second, ask what the importer holds in local parts stock and what the service intervals and warranty terms are for Grenada. On an island, waiting three weeks for a part is a far bigger cost than the difference between two chassis prices.

Questions buyers ask before signing

Can this chassis take a refrigerated box body?

Yes. It ships as a chassis at 6,934 mm overall on a 3,800 mm wheelbase, so a reefer body can be built locally in Grenada or pre-fitted before shipment. Budget the box and refrigeration unit against the 8,500 kg gross, because insulation and a nose-mounted unit eat into payload, so size the body with your builder first. The 115 kW ISF3.8 with 500 N·m has reserve for a body-driven compressor, though an independent diesel reefer unit is simpler to service.

Is 154 hp with a 4.3 ratio enough for hilly routes?

At 8,500 kg gross the ISF3.8 delivers 115 kW and 500 N·m, and the 4.3 final drive keeps the engine in its torque band on Grenada's steep, stop-start coastal roads while still allowing sensible cruising between towns. With a full load on long sustained grades you will be downshifting, which is normal for this class. If your running is mostly flat highway, a taller ratio saves fuel — give the dealer your gradient profile and ask them to check it.

Does the price include the body and shipping?

The listed price covers the chassis-cab as specified, with right-hand drive and Euro IV already built in. Bodywork, freight, insurance and destination charges are quoted separately — share your discharge port and body requirement and ask for a landed cost. Changes to cab, tyre brand, axle ratio or emission level also move the number, so settle the full specification before requesting a firm offer.

How much can it actually carry?

The sheet publishes an 8,500 kg certified gross but no rated payload figure, so the answer depends entirely on the body you fit. Ask the dealer for a weighed kerb weight on the finished vehicle, subtract it from 8,500 kg, and check the result against the 2.85-tonne front and 6-tonne rear axle ratings. On a short-wheelbase island chassis the rear axle limit is usually what you meet first.
