The Tank 700 appears to have the green light for Australia.

That’s the good news. So is the fact that it will offer GWM's vaunted new twin-turbo V8, as well as a long-wheelbase model with three-row/seven-seater capability, making it more family-friendly practicality.

The bad news is that the Toyota LandCruiser, Mercedes G-Wagen-like hybrid off-road SUV is still up to two years away from launching here, despite the debuted of a facelifted version at last month’s China Auto Show in Beijing.

According to GWM Australia Public Relations Manager Justin Stefani the company will hold out for the next redesign that is due to surface in its home market later next year or in 2028.

“There is no timing confirmed,” he said.

“It aligns with what (GWM International Vice President, James Wang) said… that, from an engineering perspective, we would look to potentially bring the 700 into Australia on the back of a new iteration.

“Because the 700 is quite an old vehicle, it’s been around for a while, so if you think about chronologically, (this just facelifted) 700 comes out, new V8 powertrain comes out, and we’d be silly to put a car in for 12 months that’s aged and then have to update it.

@carsguide.com.au Is Australia ready for a $150K-plus ultra-luxury 4x4 from China? Larger and longer than the 2026 GWM Tank 500 on which it’s based on, the Tank 700 is shamelessly inspired by the Mercedes G-Class and Land Rover Defender. #GWM #Tank700 #Mercedes #GClass #GWagen #LandRover #Defender #SUV #carsguide #fyp ♬ original sound - CarsGuide.com.au

“We’d probably wait until the next-generation is out, and then look to how that business case works.

“We’d probably say 18 to 24 months off.”

So, how actually old is the 700? Using a variation of the platform found in the Tank 500 SUV and Cannon Alpha ute, this large, design-driven body-on-frame 4x4 five-seater wagon arrived in China in early 2024.

As part of the mid-cycle update, the MY26 facelift includes a revised front-end design, new trims and updates to what’s under the bonnet.

This includes the implementation of that highly-anticipated 4.0-litre twin-turbo V8 petrol engine, to be made available with electrification. Details are to be divulged at a later time, as it has yet to hit the roads in China.

Which means, for now at least, the 700 headline is the new 3.0-litre twin-turbo internal combustion engine (ICE) petrol V6s.

First up is the 260kW/560Nm non-electrified unit, driving all for wheels via a nine-speed torque-converter auto developed in-house at GWM and shared with the China-market Cannon Alpha and Tank 500. It’s good for 0-100km/h in 8.6 seconds, 190km/h or 12.5 litres per 100km.

Next up is the Hi4-T plug-in hybrid electric vehicle (PHEV) version, adding an electric motor to up the V6’s combined power, combined torque and acceleration numbers to 385kW, 800Nm and 8.3s, while a 37.1kWh battery pack allows for under 100km of pure-EV range. This one prioritises off-road 4x4 prowess.

Finally comes the all-new, GWM-first Hi4-Z PHEV application, removing the centre differential but adding an electric motor and 59kWh battery out the back, for a WLTC (China)-claimed 190km range, as well as a 720kW and 1375Nm combined-bump in outputs, shaving 0.6s off the 0-100km/h time. This is more on-road focused, boosting efficiency significantly.

Note the latter’s additional electrification tech significantly cuts into the 700’s braked towing capacity, dropping from 3500kg to 2500kg.

Plus, cargo capacity suffers as well, from the ICE’s 490 litres to 392L (Hi4-T) and just 180L (Hi4-Z), followed by corresponding drops when the rear seatbacks are folded down, from 1601L to the Z’s 1025L.

Maybe that’s why GWM Australia has elected to wait for the next-gen model, which may have better electrification packaging so as to not compromise practicality.

With the latest electrified V6 and V8 petrol choices, combined with upgraded diesel options and the Australian Tune 1 steering and suspension upgrades by ex-Holden dynamics engineer Rob Trubiani, the 2028 700 is shaping up to be an intriguing premium off-road SUV indeed.

He rejoined John Mellor in early 2003 and has been with GoAutoMedia as a senior product and industry journalist ever since. With an eye for detail and a vast knowledge base of both new and used cars Byron lives and breathes motoring. His encyclopedic knowledge of cars was acquired from childhood by reading just about every issue of every car magazine ever to hit a newsstand in Australia. The child Byron was the consummate car spotter, devoured and collected anything written about cars that he could lay his hands on and by nine had driven more imaginary miles at the wheel of the family Ford Falcon in the driveway at home than many people drive in a lifetime. The teenage Byron filled in the agonising years leading up to getting his driver's license by reading the words of the leading motoring editors of the country and learning what they look for in a car and how to write it. In short, Byron loves cars and knows pretty much all there is to know about every vehicle released during his lifetime as well as most of the ones that were around before then.
