News in brief — updated 13 September 2026: GWM's new TANK 500 3.0-litre turbo-diesel is reaching Australian dealers with 170kW, 620Nm and a claimed 3,500kg braked towing capacity. Lux and Vanta grades are listed from $65,990 and $71,990 driveaway respectively, subject to GWM's pricing terms and local availability.
GWM has added a 3.0-litre turbo-diesel TANK 500 to its Australian range, giving buyers a seven-seat diesel alternative alongside the HEV and five-seat PHEV. The launch is especially relevant to owners who prioritise long-distance touring, low-rpm torque and heavier towing—but the headline tow rating is only one part of a safe, legal setup.

Real-world fuel use varies with load, speed, terrain, weather, tyre choice and towing conditions.
What has changed for Australian TANK 500 buyers?
The main change is the new diesel powertrain. GWM says the engine produces 170kW and 620Nm, with peak torque available from 1,400 to 2,400rpm. The company positions this low-rpm torque delivery for towing, carrying loads and difficult terrain.
GWM also lists a 3,500kg braked towing capacity, 500kg above the 3,000kg figure promoted for earlier TANK 500 hybrid variants. That makes the diesel noteworthy for caravan and trailer buyers, but it does not mean every 3,500kg trailer combination will be legal or suitable.
Lux Diesel versus Vanta Diesel
Both diesel grades use the same headline engine and towing figures. The distinction is mainly equipment and styling.
- TANK 500 Lux Diesel: listed from $65,990 driveaway.
- TANK 500 Vanta Diesel: listed from $71,990 driveaway and adds a darker exterior treatment. GWM highlights a black grille, black roof rails, electronic retractable side steps and 19-inch black alloy wheels.
Driveaway pricing can vary by location, buyer type and campaign terms. Confirm the final on-road price, build date and included equipment with a GWM dealer before ordering.
Why GWM says the diesel was developed for Australia
GWM says the 3.0-litre diesel went through an Australian engineering and validation program. Its September development story describes dyno work, heat-soak and endurance testing, then real-world validation involving corrugations, steep climbs, towing at Gross Combination Mass and hot highway running.
The company also says the development fleet was tested in Big Desert sand. These are manufacturer claims rather than an independent durability guarantee, but they explain the intended use case: long-distance Australian touring and towing.
What the 3,500kg tow rating does—and does not—tell you
A braked towing capacity is the manufacturer's maximum trailer limit under specified conditions. It is not a promise that every vehicle, passenger, accessory and trailer combination can operate at that number.
Before towing, verify:
- the exact vehicle's GVM, GCM and axle limits;
- the trailer's ATM and actual loaded mass;
- tow-ball download and its effect on rear-axle load and payload;
- passengers, luggage, fuel and fitted accessories;
- towbar, wiring, brake-controller and camera compatibility; and
- current state or territory towing rules.
A weighbridge check after the touring setup is loaded is more useful than relying on brochure maximums alone.
Accessory buyers should check powertrain and grade fitment
The diesel launch creates a new fitment branch within the TANK 500 range. Parts described only as “TANK 500 compatible” may not suit every HEV, PHEV and diesel version.
Before ordering an accessory, confirm:
- model year and build date;
- Diesel, HEV or PHEV powertrain;
- Lux or Vanta grade;
- seven-seat or five-seat cabin layout;
- left- or right-hand-drive application;
- mounting points, wiring connectors and sensor clearance; and
- whether installation affects warranty, ADR compliance, airbags or driver-assistance systems.
For high-load electrical, towing or underbody accessories, use a qualified installer and provide the supplier with clear vehicle photos or a VIN-based fitment check where appropriate.
Availability and the introductory offer
GWM's 17 August launch release said the diesel TANK 500 was expected at Australian dealerships from mid-September 2026. A newer official development page says it is available now through local dealers. In practice, colour and grade availability will vary by dealership.
GWM's current TANK 500 page also advertises a limited-time $2,000 driveaway cash bonus or $2,000 fuel card for eligible new 3.0-litre diesel purchases before 31 October 2026. Offers can change or end, so check the current GWM terms rather than relying on this article when making a purchase decision.
