Ahead of its release, the powertrain underwent six months of grueling local engineering and validation testing across Australian environments, led by GWM ANZ Vehicle Dynamics Manager Rob Trubiani.

GWM Australia has officially opened expressions of interest for its heavily anticipated, all-new 3.0-litre turbo-diesel engine. Scheduled to make its global debut right here in Australia and New Zealand this September, the high-output powertrain will be offered exclusively in the Tank 500 large SUV and the premium Cannon Alpha dual-cab ute.

Engine Deconstructed: Four Cylinders, V6-Beating Torque

It is critical to note that despite its large 3.0-litre displacement, this is a four-cylinder engine, matching the Isuzu D-Max and MU-X for the title of the largest-displacement four-cylinder turbo-diesel currently available in Australia.

Paired with a GWM-developed nine-speed automatic transmission and a four-wheel-drive system, the engine produces 170kW of power and a massive 620Nm of torque.

GWM’s new four-cylinder makes a formidable statement against established segment leaders. Its 620Nm of torque officially outmuscles the highly regarded 3.0-litre V6 turbo-diesel found in the Ford Ranger and Everest (which produces 600Nm). While Ford's V6 retains a slight power advantage (184kW vs GWM's 170kW), the GWM completely obliterates its 3.0L four-cylinder rival from Isuzu, which musters only 140kW and 450Nm.

Tank 500: Replacing Hybrid Power for Diesel Durability

For the Tank 500 seven-seat SUV, the arrival of the 3.0L diesel marks a major lineup shift. GWM has confirmed the new diesel engine will actively replace the current 2.0-litre turbocharged petrol-electric hybrid variants, which are now entering run-out mode.

Buyers should note that this transition represents a slight drop in outright paper performance; the outgoing hybrid produced a combined 255kW and 648Nm, compared to the new diesel’s 170kW/620Nm. However, GWM expects CO2 emissions to remain broadly comparable, while the diesel architecture delivers the low-end grunt and thermal durability heavily preferred by Australian buyers for long-distance touring and heavy towing. Fuel consumption is rated at a claimed 7.1L/100km.

Cannon Alpha: A Massive Upgrade over the 2.4L

In the Cannon Alpha premium dual-cab ute, the new 3.0L unit will directly replace the existing 2.4-litre turbo-diesel. This swap yields a colossal performance jump of 35kW and 140Nm over the old 2.4L engine.

Remarkably, the larger engine is also significantly more efficient. GWM claims an average fuel economy of 7.3L/100km for the 3.0L Cannon Alpha, representing a massive efficiency gain over the outgoing 2.4L model, which carried a thirstier 8.9L/100km rating. Both the Cannon Alpha and the Tank 500 will retain a maximum braked towing capacity of 3,500kg.

Fuel consumption figures provided (7.1L to 7.3L/100km) are based on the more lenient NEDC testing cycle, meaning real-world consumption will likely be higher depending on payloads and towing conditions.

Looking further ahead, GWM confirmed that this new 3.0L block has been designed to integrate with future hybrid and plug-in hybrid (PHEV) architectures, which are expected to enter production in China by early 2027.
