Six hundred and sixty horsepower for an urban delivery truck is the sort of specification that makes a finance director ask whether someone has added a zero by mistake. It is worth taking that reaction seriously, because the Foton Auman Galaxy 6x4 660HP is listed for both cold chain and urban delivery work, and those two jobs rarely want the same machine. What the numbers actually describe is a heavy tractor with a 55,000 kg GCW, a 14.5-litre Cummins producing 3,200 Nm from 900 rpm, and a ZF twelve-speed with a retarder. That is serious hardware. Whether your operation needs it — or is simply paying for capacity it will never use — is the question this review is here to answer.

What the specification sheet commits to

Two identical columns are published, which makes the sheet easy to read. Drive is 6×4. Overall dimensions are 7,115 × 2,525 × 3,950 mm on a 3,300 + 1,350 mm wheelbase. Maximum GVW/GCW is 55,000 kg, kerb weight is 8,870 kg, and payload is listed at 46,000 kg with two seats. Ground clearance is 250 mm, tyres are 12R22.5, and suspension is two leaf springs at the front and three at the rear. The frame is specified as 225/286 × 80 × (8+L).

The engine is the Cummins X15NS6B660 — 14.5 litres, 660 ps, Euro VI, with maximum torque of 3,200 Nm delivered between 900 and 1,400 rpm. That torque band is the single most important figure on the page. An engine making its maximum from 900 rpm does not need to be revved to pull, which is why a 660 hp unit can be driven economically at part throttle — and why it copes with repeated pull-aways with a heavy insulated box and a refrigeration unit drawing power.

Gearbox and retarder: the specification that justifies the engine

The transmission is the ZF12TX3221TO, supplied with a retarder. Foton's product copy describes the pairing as the FOTON Super Power Train and refers to a ZF AMT gearbox, so confirm with the distributor whether the unit you are ordering is the automated or the manual variant — for stop-and-go urban work and for a driver pool of mixed experience, that distinction changes both the driving experience and the clutch budget.

"A retarder is not a luxury on a 55-tonne combination. It is the difference between arriving with brakes and arriving with a smell."

The rear axle is a 10-tonne unit at a 3.364 ratio. That ratio is a deliberate compromise: it keeps the engine inside its 900–1,400 rpm torque band when fully loaded at 55,000 kg GCW, but it holds higher revs at cruising speed than a 2.7-class ratio would. You pay for that on flat motorway legs and you are repaid in gradeability and responsiveness everywhere else. Tell the distributor your trailer weight and average speed and make them sanity-check the ratio against your actual route rather than a brochure average.

Is 660 hp right for urban cold chain, or too much truck?

Honest answer: it is more tractor than a pure city round needs. At 8,870 kg kerb weight and 55,000 kg GCW, you are buying capacity that only pays back on intercity legs. If your work is genuinely door-to-door urban delivery at modest weights, a mid-range chassis will cost less to buy, less to tax and less to insure, and it will be easier to park.

The counter-argument is duty cycle rather than headline power. Repeated pull-aways with a heavy insulated box, a refrigeration unit drawing power, and a driver who needs to keep to a schedule in traffic: that is where 3,200 Nm from 900 rpm and a twelve-speed with a retarder earn their keep. The specification is defensible for regional cold chain trunking with an urban leg at each end. It is much harder to defend for a city-only parcel round.

Can the chassis take a refrigerated box?

This listing is the tractor rather than a finished refrigerated truck, and that is an important commercial distinction. The insulated body, the refrigeration unit and any tail-lift are specified separately, and they must be matched to the 3,300 + 1,350 mm wheelbase and the 55,000 kg GCW. The driveline helps: the twelve-speed ZF with retarder and the 10-tonne rear axle at 3.364 are specified with heavy insulated bodies in mind, and the frame at 225/286 × 80 × (8+L) is a substantial section.

What you must do yourself is close the loop between three parties — the chassis supplier, the bodybuilder and the refrigeration unit supplier — before anyone commits to a build slot. Send your box dimensions and the unit brand to the distributor and make them confirm compatibility in writing. Also establish how the refrigeration unit is driven, because a unit drawing from a tractor that was never specified with it in mind is a fuel and reliability problem you will own for years.

Cab, safety and driver acceptance

The Galaxy cab is high roof and high floor, and the equipment list is aimed squarely at driver comfort: a car-style dashboard, extra-large storage, power glass, central control lock, remote locating, LCD combination instruments, automatic air conditioning, an air-cushioned adjustable driver seat, and a Cummins integrated intake system credited with reducing noise. Foton also claims precision wind resistance testing delivered over 3% better fuel economy.

On safety, the cabin is described as complying with European collision standards, with ABS+ASR+ESP, wide-angle rearview mirrors, LED daytime running lamps, a distinctive cross lamp design, a double-acting safety lifting cylinder and a suspension lock alarm. Foton attributes a 12.4% accident reduction to the lighting and mirror package. As with any manufacturer claim, read it as a design intent rather than an audited outcome — but the electronic safety package itself is a concrete, checkable list.

Price, value and what to confirm

At 78,000 USD, this is a very different proposition from the mid-range chassis in the same catalogue, and the premium buys engine, gearbox, retarder, axle and cab rather than badge. A Cummins X15 and a ZF gearbox are components your workshop and your parts supplier will recognise, which materially reduces the risk of buying an unfamiliar marque. The residual question remains: Foton has not yet earned European-level residuals in most export markets, so model the deal on cost per tonne carried over your ownership period.

"Buy the Cummins and the ZF, question the badge, and price the truck on cost per tonne carried."

No country of sale is listed for this vehicle, so shipping, right-hand or left-hand drive availability and local homologation all need confirming with the distributor before you commit. Add the gearbox variant, the axle ratio and the refrigeration drive arrangement to the order in writing.

Questions buyers ask before signing

Is 660 hp right for urban cold-chain delivery?

It is more tractor than a pure city round needs, and that is worth weighing. The X15NS6B660 makes 3,200 Nm from just 900 rpm, which helps when pulling away repeatedly with a heavy insulated box and a refrigeration unit drawing power, and the twelve-speed ZF with retarder plus ABS, ASR and ESP suit stop-and-go traffic. But at 8,870 kg kerb weight and 55,000 kg GCW, you are paying for capacity that only pays back on intercity legs.

Can the chassis take a refrigerated box?

This listing is the tractor rather than a finished refrigerated truck, so the insulated body, refrigeration unit and any tail-lift are specified separately and must be matched to the 3,300 + 1,350 mm wheelbase and the 55,000 kg GCW. The twelve-speed ZF with retarder and the 10-tonne rear axle at 3.364 handle heavy insulated bodies, and the frame is 225/286 × 80 × (8+L). Send your box dimensions and unit brand and have the distributor confirm.

How does the 3.364 ratio affect fuel use?

The 3.364 rear axle ratio with the twelve-speed ZF is a compromise setting: it keeps the 660 hp engine inside its 900–1,400 rpm torque band when fully loaded at 55,000 kg GCW, but holds higher revs at cruising speed than a 2.7-class ratio would. That costs some fuel on flat motorways and buys gradeability and responsiveness elsewhere. Give the distributor your trailer weight and average speed and have them sanity-check the ratio.
