2026 GWM Tank 300 Ultra PHEV Review

The GWM Tank 300 has rapidly established itself as a formidable contender in the Australian off-road SUV market, marrying traditional body-on-frame ruggedness with a striking, retro-modern aesthetic. Now, with the introduction of the Hi4-T Plug-in Hybrid Electric Vehicle (PHEV) variant, GWM is attempting to bridge the gap between  heavy-duty off-road capability and  modern electrification.  It  is  a  bold  move, promising pure electric urban driving alongside hybrid-assisted touring, all wrapped in a package that undercuts established market heavyweights on price while overloading on standard equipment.

For high-intent buyers navigating the evolving landscape of electrified utility vehicles, the key question is not just whether the Tank 300 PHEV is cheap, but whether its complex powertrain delivers genuine utility. Does the transition to a plug-in hybrid system compromise the raw off-road pedigree? How accurate are the highly touted efficiency figures in real-world Australian conditions? In this comprehensive YEECAR 3.0 review, we strip away the marketing jargon to analyze the pricing, packaging, running costs, and driving dynamics of the 2026  GWM Tank 300  Ultra  PHEV,  ensuring  you  have  the  transparent  data needed to make a confident purchasing decision.

How much does the GWM Tank 300 cost?

Pricing  is  undeniably  one  of  the  GWM  Tank  300's  strongest  strategic  advantages  in  the  Australian market. GWM employs a transparent, national drive-away pricing structure, eliminating the traditional dealership haggling process and providing high-intent buyers with immediate financial clarity.

The  core  Tank  300  range  opens  at  an  accessible  $47,990  drive-away  for  the  Lux  diesel  variant, establishing  a  highly  competitive  baseline.  However,  stepping  into  the  electrified  lineup  requires  a premium. The PHEV variants represent the pinnacle of the Tank 300 price structure, positioned above both the standard petrol and traditional hybrid models.

The Lux PHEV kicks off the plug-in range at $57,990 drive-away. For an additional $4,000, buyers can upgrade to the flagship Ultra PHEV tested here, priced at $61,990 drive-away. Despite sitting at the top of the  range,  this  pricing  remains  exceptionally  aggressive  when  benchmarked  against  large,  off-road capable, body-on-frame SUVs from legacy brands, particularly when factoring in the sheer volume of included technology and the sophisticated plug-in hybrid drivetrain.

What is the GWM Tank 300 like on the inside including dimensions?

The interior of the Tank 300 is a masterclass in blending rugged utilitarianism with unexpected luxury, though it arrives in the Australian market retaining its original layout rather than adopting the updated cabin  design  recently  released  in  China.  This  is  far  from  a  disadvantage;  the  cabin  possesses  a distinctive, quirky charm heavily inspired by premium European styling cues—most notably the turbine- style air-conditioning vents, the prominent central analogue clock, and the dual-screen digital dash layout reminiscent of previous-generation Mercedes-Benz vehicles.

Material quality in the top-spec Ultra is surprisingly premium for this price bracket. The upper dashboard and armrests feature soft-touch, squidgy materials, and the Nappa leather seat upholstery feels supple and supportive. Comfort is a priority, with the front seats offering electrical adjustment, heating, and ventilation, while the driver benefits from a power lumbar support and a massage function. However, cost-saving measures become apparent lower in the cabin, where harder, scratchy plastics are utilized.

Technologically, the cabin is dominated by a pair of  12.3-inch displays  handling  instrumentation  and infotainment. The system includes 3D inbuilt navigation, AM/FM/DAB+ radio, and crucial smartphone integration  via  wireless  Apple  CarPlay  and  Android  Auto.  While  feature-rich,  the   reliance  on  the touchscreen for basic functions like climate control adjustments and drivetrain settings can be distracting on the move.

Dimensions and practicality

The Tank 300 presents an imposing physical footprint, measuring 4760mm in length, 1930mm in width, and  1903mm  in  height,  riding  on  a  2750mm  wheelbase.  This translates to  excellent  headroom  and adequate legroom in the front row. However, second-row accommodation is slightly compromised. While knee and toe room are acceptable for average-sized adults, the cabin does not feel as expansive as some  longer-wheelbase  competitors,  and  the  rear  seats  cannot  slide  fore  and  aft  (though they  do recline). Rear passengers are treated to directional air vents, USB-A charging ports, and a fold-down armrest.

The most significant packaging compromise introduced by the PHEV system is in the cargo area. The integration of the large 37.1kWh battery pack raises the boot floor, resulting in a slightly higher loading lip and reduced overall volume compared to non-hybrid models. The side-opening tailgate reveals a modest 360 litres of capacity with the rear seats in place, expanding to 1520 litres when folded flat. While not class-leading, it remains practical for daily use and includes useful features like a 220V AC power socket (supported by Vehicle-to-Load V2L capability), shopping bag hooks, and secure tie-down points.

What's under the bonnet?

The headline attraction of the Tank 300 PHEV is its highly complex and extraordinarily potent powertrain. Eschewing a large-capacity naturally aspirated or diesel engine, GWM has paired a 2.0-litre four-cylinder turbocharged petrol engine with a robust electric motor and a substantial 37.1kWh Nickel Manganese Cobalt (NMC) high-voltage battery.

This hybrid architecture is mated to a nine-speed hybrid automatic transmission that delivers power to a part-time 4x4 system, retaining the crucial ladder-frame chassis setup essential for durability. The total system outputs are staggering for a vehicle in this class: a claimed 300kW of power and an earth-moving 750Nm of torque. This immense thrust propels the heavy SUV from 0-100km/h in a sportscar-rivalling 6.3 seconds.

When it comes to charging, the Tank 300 PHEV is equipped for both AC and DC replenishment. The onboard AC charger accepts up to 6kW, requiring approximately 6.5 hours to charge the battery from 15% to 100%. More critically for on-the-go usability, it supports 50kW DC fast charging, allowing the battery to jump from 30% to 80% capacity in just 24 minutes. This battery enables a claimed electric-only driving range (NEDC standard) of 115km, providing genuine zero-emission urban commuting potential before the petrol engine is required.

For touring, the combined powertrain (fully charged battery plus a 75L fuel tank) yields a theoretical maximum range of up to 900 kilometres. For those towing caravans or boats, the vehicle supports a competitive 3000kg braked towing capacity.

How does the GWM Tank 300 drive?

Driving the Tank 300  PHEV is an experience defined by dualities: it is incredibly fast yet undeniably heavy, comfortable on the highway but slightly nervous in the corners.  Forward visibility is generally excellent, aided by a commanding seating position, though rearward vision is somewhat impaired by the boxy design and the tailgate-mounted spare wheel. Thankfully, a superb, high-resolution 360-degree surround-view camera system completely mitigates parking anxiety.

Acceleration  is the  most  startling  aspect of the driving experience. When the throttle  is  pinned, the combination of electric torque and turbocharged power acts like a slingshot, pushing you back into the Nappa  leather  seats.  However,  this  straight-line  speed  highlights  the  vehicle's  dynamic  limitations. Weighing in at a hefty 2615kg (kerb weight), the mass is palpable. The brake pedal exhibits a spongy, unrefined feel, demanding a firm press during emergency stops to arrest all that momentum.

Handling is similarly compromised by the vehicle's architecture and weight. The coil-sprung suspension absorbs large bumps and road imperfections beautifully, delivering a highly comfortable and relaxing ride on straight stretches. Yet, in corners, noticeable body roll is present. The steering calibration is also a point of contention; in its 'Comfort' setting it feels overly light and disconnected, while switching to 'Sport' mode makes the rack hyper-reactive, resulting in a twitchy feel at speed.

Ergonomically,  the   driving  experience  is  marred  by  persistent  GWM  quirks.  The  indicator  stalks frequently fail to self-cancel, throttle tip-in can feel lurchy at low speeds, and the active safety systems— particularly the lane-keeping assistant and driver monitoring chimes—can be intrusive and over-reactive, though thankfully many can be adjusted or disabled via the touchscreen.

Off-Road Capability

Despite the hybrid complexity, the Tank 300 retains its off-road pedigree. The driver has access to a traditional part-time 4WD dial (2H, 4H, and 4L), augmented by various terrain modes, off-road cruise control,  hill  descent  control,  and  a  clever  'Trail  Turn  Assist' which  brakes  the  inside  rear wheel  to drastically tighten the turning circle on narrow tracks. The flagship Ultra grade boasts both front and rear locking  differentials.  With  222mm  of  ground  clearance,  a  32-degree  approach  angle,  a  33-degree departure angle, and a wading depth of 700mm, it possesses the physical geometry to tackle highly technical trails, even if the sheer weight of the PHEV system requires slightly more careful momentum management than the lighter ICE variants.

What are the standard specifications for each variant?

GWM has adopted a high-specification strategy for the Australian market, ensuring even the entry point to the PHEV range is lavishly equipped. The range is split into two distinct trim levels: Lux and Ultra.

Furthermore, the PHEV variants (alongside the Ultra Hybrid) receive an upgraded parking sensor array (six sensors front and rear, up from four), Highway Assist, Intelligent parking assist, and Reverse assist technology.

How much does the GWM Tank 300 cost to run?

Running costs for  a  PHEV  are  highly  contingent  on  charging  discipline.  GWM  claims  a  remarkable combined fuel economy figure of 1.9L/100km, accompanied by an energy consumption rate of 27.2kWh/ 100km. However, real-world testing paints a more nuanced picture.

In  mixed  testing  conditions,  fuel  economy  averaged  9.4L/100km,  with  energy  consumption  at  an impressive 8.7kWh/100km while the battery held charge. During this testing, an electric-only range of approximately 80 kilometres was achieved—short of the 115km NEDC claim, but highly practical for daily urban commuting without firing the petrol engine.

The critical data point for buyers is the depleted battery performance. When the high-voltage battery is drained, the heavy 2.0L turbocharged SUV relies heavily on its combustion engine, effectively operating as a mild hybrid.  In this state,  highway fuel consumption spiked to around  13L/100km. Therefore, to unlock the economic benefits of the Tank 300 PHEV, owners must have reliable access to daily charging infrastructure.

Servicing and warranty

GWM backs the Tank 300 with an aggressive ownership package designed to instil confidence. The vehicle is covered by a 7-year, unlimited-kilometre warranty, while the high-voltage battery receives an 8- year, unlimited-kilometre warranty. Seven years of roadside assistance is also included.

Servicing intervals are set at 12 months or 10,000km for the first visit, extending to 15,000km thereafter. GWM offers a 7-year capped-price servicing program, totalling $4,055 over the period, which averages out to a reasonable $579.26 per year.

Yeecar's verdict on the Tank 300 PHEV

The 2026 GWM Tank 300 Ultra PHEVis a paradox of incredible value, brute force, and heavy engineering. If you require genuine off-road capability paired with zero-emission urban commuting—and you have the charging infrastructure to support it—it stands unmatched at this price point. However, buyers must be prepared for the handling compromises inherent to its heavy kerb weight and the steep increase in fuel consumption on long trips once the battery is depleted. For the high-intent buyer valuing sheer equipment levels and aggressive pricing, it is a compelling, if imperfect, proposition.
