GWM Australia has recorded a successful five-from-five result on the Beer O’Clock Hill off-road climb this month.

The testing included the brand's latest electrified models, the Tank 300 Hi4-T PHEV and the Tank 500 Hi4-T PHEV.

Most notably, the Tank 300 Hi4-T PHEV reached the summit in full production specification while fitted with standard highway tyres.

Other vehicles in the successful group included the Cannon XSR, the Cannon Alpha Hi4-T PHEV, and the Tank 300 Diesel.

The Cannon Alpha Hi4-T and Tank 300 Diesel utilised Mickey Thompson all-terrain tyres during their respective ascents.

Each vehicle involved in the testing completed the climb without mechanical modifications, software upgrades, or calibration changes.

The Tank 300 Hi4-T features a 2.0-litre turbocharged petrol engine paired with a 120kW electric motor.

This system delivers a combined output of 300kW and 750Nm of torque through a nine-speed hybrid automatic transmission.

The Hi4-T architecture integrates a 37.11kWh battery, providing an electric driving range of up to 115km on the NEDC cycle.

Mechanical off-road features across the range include a ladder-frame chassis, a low-range transfer case, and locking differentials.

The Tank 500 Hi4-T variant also utilised during the climb features triple locking differentials and an 800mm wading depth.

GWM Australia confirms the Tank 300 Hi4-T will arrive in local showrooms in early April 2026.

Launch pricing for the Tank 300 Hi4-T starts at $55,990 drive-away for the Lux and $59,990 drive-away for the Ultra.

The Tank 500 Hi4-T is currently priced from $79,990 drive-away, with a limited-time launch offer of $77,990.
