2027 GWM Tank 300L detailed as longer, PHEV-only off-roader, not yet confirmed for Australia

GWM’s new Tank 300L was revealed last week, and now the Chinese brand has released specifications for its stretched off-road SUV.

However, Australian release timing has yet to be announced for the new model.

"This remains a domestic market release only at this stage. As with all new products released, our local team will review and assess the options and fit for our local consumers," said a GWM Australia spokesperson in a statement.

The Tank 300L gains a less off-road-oriented Hi4-Z plug-in hybrid (PHEV) powertrain, as seen in China in the Tank 500 and Tank 700.

It still features a 180kW/380Nm turbocharged 2.0-litre four-cylinder petrol engine, however, it’s mated with a 59.6kWh ternary lithium battery and an electric motor on each axle.

The front motor produces 180kW and 400Nm, while the rear motor produces 200kW and 415Nm. All up, GWM claims total system outputs of 560kW and 1195Nm.

This rockets the Tank 300L to 100km/h in 4.3 seconds, down from 6.1 seconds in the Tank 300L Hi4-T.

Claimed electric range is 200km on the WLTC cycle, with fuel consumption of 0.85L/100km or 8.35L/100km at the lowest state of charge. The Hi4-Z uses a 77L fuel tank, instead of 70L in the Hi4-T.

Instead of a nine-speed automatic transmission and a part-time four-wheel drive system like the Hi4-T, there’s what GWM describes as a power split and three-speed front drive module, along with an ‘intelligent electric’ four-wheel drive system.

Ground clearance is 1mm higher at 235mm, while approach and departure angles are essentially identical to the Hi4-T at 38 degrees and 33 degrees respectively – the latter just one degree lower than the Hi4-T.

GWM Australia has said it sees "potential" for a Hi4-Z-equipped model in our market, but hasn't confirmed when we can expect to see one here and which Hi4-Z model it'll import.

The Tank 300L Hi4-T uses a 130kW/495Nm front electric motor, giving it total system outputs of 310kW and 750Nm. This is up somewhat from the Tank 300 PHEV sold here, which uses a 120kW/400Nm electric motor and has total system outputs of 300kW and 750Nm.

The battery remains a 37.1kWh ternary lithium unit, with claimed electric-only driving range of 105km on the WLTC standard, and fuel consumption of 3.15L/100km – or 8.45L/100km on the lowest state of charge.

GWM Australia touts figures of 115km, 1.9L/100km and 8.3L/100km, respectively, for the existing Tank 300 PHEV.

For now, the Tank 300L isn’t being offered with the petrol and diesel powertrains seen in the regular Tank 300, which received a new interior in 2025.

The Tank 300L looks much the same as the familiar Tank 300 – right down to the lighting elements – but differs with a significantly longer bonnet thanks to a stretched wheelbase.

The new model now measures 4886mm long, 1984mm wide and 1927mm tall on a 3010mm wheelbase. The outgoing model, in contrast, measures 4760mm long, 1930mm wide, 1903mm tall and rides on a 2750mm wheelbase.

The Tank 300L gains a LiDAR unit which, along with three millimetre-wave radar, 12 ultrasonic radar, and 11 cameras, powers a suite of active safety and driver assist features. This includes a Navigation on Autopilot feature, promising Level 2 autonomous driving on all types of roads, from parking space to parking space.

The stretched SUV also features a Night Vision system, with footage from a thermal imaging camera displayed within the 12.3-inch digital instrument cluster.

There’s also a 15.6-inch touchscreen infotainment system running the automaker's latest Coffee OS 3.0 operating system.

Apart from a slightly larger touchscreen (up from 14.6 inches), the Tank 300L’s interior is essentially identical to the updated Tank 300 launched in China last year.

For now, the Tank 300 will continue in Australia in regular-length guise and with a choice of diesel or Hi4-T PHEV powertrains, with the regular hybrid gone and the base turbo-petrol four-cylinder engine being phased out.

GWM Australia opted not to import the new interior design revealed in China last year as it includes a column-mounted gear selector stalk, instead of a chunky, console-mounted shifter.

It said research found Australians didn’t like the column shifter, and there was no way to get the new interior without this. However, GWM warned it may be forced to accept a column-mounted shifter with the a next-generation Tank 300.

It’s unclear how much longer production will continue of the existing, regular-length Tank 300 diesel and Hi4-T sold here.

The Tank 300 was launched in China in 2020, with customer deliveries commencing in Australia early in 2023.
