GWM Tank 500 vs MG Im6

What's the difference?

The GWM Tank 500 Ultra PHEV is an impressive five-seat 4WD wagon. It’s reasonably nice to drive, it’s comfortable and it’s a capable 4WD. These vehicles keep improving and are increasingly stacked with characteristics to like.

There are still glaring range-specific issues with some of its driver-assist tech and its plug-in hybrid set-up doesn’t offer the fuel economy you’d hope for. At least not under real-world testing conditions. But the Tank 500 is packed with features and represents decent value-for-money when cross-shopped against the likes of its stablemate the regular hybrid, or the Prado and Everest.

A super solid first outing from the IM brand. Don't let the pricing fool you, there is still bang for buck on offer in the IM6 Performance, even if it at times feels a bit too digital for my tastes.

In terms of dimensions, the Tank 500 Hi4-T PHEV is 5078mm long (with a 2850mm wheelbase), 1934mm wide and 1905mm high. It has a listed kerb weight of 2820kg, so it’s not an insubstantial vehicle.

There are plenty of old-school 4WD design cues in the Tank 500’s appearance. It’s mostly chunky and straight up and down, with some softer curves here and there as concessions to contemporary styling.

It's clear to see where the GWM Tank 500 takes its cues from – most of the current crop of popular 4WD wagons, such as the Toyota LandCruiser 300 Series.

The Tank 500 is a large vehicle straddling that line between large and extra-large 4WD wagons. It is longer than any 300 Series, but it’s narrower and shorter.

It has a sunroof, roof rails, electric side steps (that extend when doors are opened and retract when doors are shut) and 18-inch alloy wheels.

The interior is well laid-out and functional with some understated class to it. There are soft-touch surfaces and genuine Nappa leather seating throughout.

I feel almost mean saying this, because there will be plenty of people who like the way the IM6 looks, and I don’t want to rain on their parade. But… I’m not one of them.

It reminds me a bit of the pre-facelift Tesla Model Y, in that it’s largely feature-less and a bit blobby, and there’s not a sharp angle anywhere to be found on the thing. Premium to me means powerful and assured — picture just about any Audi — whereas I just find this a bit bland and soft.

Anyway, I do like the big alloys, the insulated glass roof and the light treatment front and rear.

And I like the cabin. The seats aren’t leather, but they’re super thick and comfortable, and there is a genuinely premium air in the cabin, helped by the acreage of screens and the quality elements, like the little door panels.

The doors unlatch electrically, matching the pop-out door handles outside, but they can be a bit fidgety. Someone from MG told me how they worked (you kind of cover the handle and let the door come to you) but I watched everyone else who tried to open them struggle. If you're at the point where you have to explain how a door handle works, you might have over-egged the pudding.

The second screen below the main one acts a bit like a mobile phone. You can alter your home screen widgets and access the main menu, even as Apple CarPlay is synched at the top. You’ll get used to it, I’m sure, but I found it to be a bit fidgety.

Actually it reminds me a little bit of the Lexus trackpad, or whatever that hateful system was called, where you controlled the main screen via a little mousepad thing, though happily it’s nowhere near as annoying as that was.

This Tank 500 has five seats because the two at the very rear have been removed to accommodate the hybrid battery.

The front seats are Nappa leather, power-adjustable (eight-way for the driver, six-way for the front passenger), as well as being ventilated with massage and memory functions.

The three-position second row – set up in a 60/40 split-folding configuration – breaks the usual 4WD wagon second-row seat tradition of being fine but not fantastic. The second-row set-up in this Tank is a first-class-cabin-style back seat with a flip-down control console (which includes air-con controls) instead of a basic centre armrest.

As mentioned there is no third row in this Tank 500 because of its underfloor battery.

Up front, the 14.6-inch multimedia screen (with wireless Apple CarPlay and Android Auto) dominates the dash. It's generally easy enough to use, although I had difficulty getting my iPhone hooked up to the system and the cabin set-up remains clunky and counter-intuitive in its operation.

The cabin has wireless charging, front and rear USB ports, as well as 12V and 220V power outlets.

The second row folds away to expand the rear storage capacity. Cargo volume is a listed 640 litres when all seats are in use and 1400 litres when the second row is stowed away.

The rear cargo area has tie-down points and a cargo slide cover.

The IM6 measures 4904mm long, 1988mm wide and 1669mm tall, and it rides on a 2950mm wheelbase, with IM describing it as a "mid-large SUV", though I expect it will be classed as a medium SUV Australia.

That said, ICE and EV mid-size electric SUVs are not cut from the same cloth, with the latter making use of a flat floor to maximise space. And so it is with the IM6, where backseat room is pretty damn impressive. I’m 175cm, and I had no problem at all with legroom or headroom, plus the same plush seats from up there are in the back, too.

There are also air vents but no temperature controls, and while there are USB ports, there is no regular household-style plug in the cabin. 

The glass in the windows is laminated, while the roof is double glazed, which MG tells me is Australian summer-proof, but I guess we'll know for sure in a couple of months.

There’s no shortage of cargo room either. There’s a 32-litre frunk up front, and there’s 646 litres in the boot with the rear seats in place. They’re 60/40 split, and if you drop them, luggage space grows to 1621 litres.

The towing capacity is a braked 1500kg, too, but I don’t expect to see many of these towing a camper trailer around.

Premium play means more premium prices, and my IM6 Performance will set you back $80,990 on the road. That might have just sent your eyebrows skyward, but keep in mind it’s faster than some Ferraris, and is swimming with high-end tech, so the bang-for-buck factor is actually still pretty good.

There are cheaper ones, too. The single-motor Premium grade is $60,990 drive-away, albeit with less power and slower charging. Then there’s the Platinum, with a bigger battery and faster charging, which is $69,990

The Performance, though, gets everything IM has to give, including an 800-volt architecture, which means super-fast charging, as well as twin motors, brutal acceleration, a decent driving range and adaptive air suspension.

Elsewhere, you get LED lighting, a big and insulated glass roof, and 20-inch alloy wheels. Inside, there are thick and soft synthetic leather seats that are heated and cooled in both rows, a banging 20-speaker sound system, and wireless charging to pair with wireless Apple CarPlay and Android Auto.

There’s also 'active noise cancellation', and a seat-aware digital assistant which is about the best, and fastest, I’ve ever used. The IM6’s speaker system can locate where a voice is coming from, so any passenger can use the assistant. For example, if you’re in the backseat and say 'hey IM, lower my window', only your window opens. It’s a technology that I specifically remember the German brands crowing about not so long ago.

There’s also a 10.5-inch central touchscreen that controls much of the vast 26.3-inch screen that runs from in front of the driver to the centre of the cabin, as well as clever little magnets embedded in the dash in front of the driver, as well as in the back of the front seat headrests, that are designed to hold phones, iPads or other little accessories.

Also cool is the IM6’s self-parking tech, but there’s also a relatively useless crab walk function, which leans on the rear-wheel steering system to drive diagonally at slow speeds. I’m still not entirely sure when you’d use that one, to be honest.

Honestly, it’s a lot of stuff, and a lot of tech.

Every Tank 500 Hi4-T PHEV has a 2.0-litre turbo-petrol engine, a 37.11kWh lithium-ion battery and an electric motor. And that combination produces a total* of 300kW and 750Nm. 

* Electric motor 120kW, petrol engine 180kW at 6000rpm. Motor 400Nm, engine 380Nm at 1700-4000rpm.

This system is mostly seamless in operation but as for GWM’s claims that it delivers “outstanding efficiency, performance, and refinement smooth, responsive take-offs, strong acceleration, and exceptional fuel savings - while ensuring minimal noise and maximum driving confidence”. Well, let’s just say this Tank 500 gets off the mark well for a large 4WD but the prompting requires a heavy right foot.

It is generally quiet and comfortable and yields a smooth driving experience. And as for fuel saving, flick your eyes down to ‘Efficiency’ to see how it did on this test.

This Tank 500 has a nine-speed automatic transmission, low- and high-range 4WD gearing, as well as a front, centre and rear diff lock.

This is the real party trick of the IM6, because there’s a nuclear power plant under the metal somewhere. All up, the twin-motor setup produces a total 578kW and 802Nm, though I suspect you’re never accessing all the grunt all at once. Still, 100km/h zips by in 3.4 seconds, and the top speed is 239km/h. For the record, that’s exactly as fast the Ferrari Roma Spider I recently handed back, so yeah, it’s properly supercar quick.

Official fuel consumption is 2.1L/100km on a combined cycle on regular unleaded fuel (91) with low-charge consumption at 8.4L/100km. For reference, low-charge fuel consumption on this test was 10.2L/100km as recorded. Okay, but not a particularly compelling result.

The Tank 500 has a 70-litre fuel tank so, going by those fuel figures, you could reasonably expect a driving range of about 686km out of a full tank.

Also on board is a 100kWh Nickel-Cobalt-Magnesium battery that produces a WLTP driving range of 505kms. Pretty good.

Charging is strong, too. The high-tech platform allows for 396kW DC fast charging, which is faster than what is currently offered in Australia. The claim is 30-80 per cent charged in 15 minutes. There’s also an external vehicle-to-load (V2L) port.

The Tank 500 Hi4-T PHEV is decent on road – and that’s good news for anyone thinking about buying this large 4WD.

It has more power and torque than its hybrid stablemate (300kW/750Nm vs 255kW/648Nm) for general day-to-day drivability while it retains all of the regular hybrid’s positive driving characteristics and few of the negatives.

This Tank 500’s turbocharged petrol engine and the electric motor work seamlessly together, with no discernible clunking or shifting between systems in the powertrain.

This is a big, heavy four-wheel drive – even heavier in this plug-in hybrid form than the regular hybrid because of this vehicle’s battery. But it is nicely settled and composed because of that weight.

This flip side is the extra heft on-board means there is some body-roll to this vehicle. It’s noticeable, but not a deal-breaker.

On highways, sealed surfaces or well-maintained bush tracks the Tank 500 is quite impressive. It’s settled, controlled and quite nice to drive.

Overall, this Tank 500’s suspension – double wishbone independent with coil springs at the front, and multi-link live axle with coil springs at the rear – is firm. There has been talk of it having been retuned for Australian conditions, but it remains stiff and jittery at pace, especially through backcountry bitumen in poor condition and lightly corrugated dirt roads. However, GWM informs me that the suspension set-up will undergo more retuning for Australian conditions and those changes will be incorporated into 2026 production vehicles.

Besides that, the engine, electric motor and transmission work quite well together. It is a reasonably smooth 4WD wagon to drive.

There are, however, glaring issues with the driver-assist tech, which is quite annoying in its operation. It’s either very jarring or intrusive in its application (example: adaptive cruise control braking way too early), or bloody annoying/dangerous (example: road-sign recognition abruptly tried to cut my speed from 100km/h to 40km/h because it registered the school zone sign off to the side of the highway. At the time it was outside school drop-off and pick-up times anyway.).

You can switch off the driver-assist features every time you start up, but the system resets and defaults to being annoying again when you switch off.

When it comes to 4WDing though, the good news returns.

This hybrid retains all of the regular Tank 500’s 4WD mechanicals, including the (BorgWarner-sourced) transfer case with high- and low-range 4WD, and it offers up plenty of torque across a decent spread of revs.

The off-road traction control system is suitably dialled in, hill descent control is effective, keeping you to a nice controlled low speed and there’s low-speed cruise control or the equivalent that keeps the vehicle to a controlled pace across varying terrain.

Not forgetting, the Tank 500 is triple locked – front, centre and rear diff locks – so there are few excuses to not be able to crawl over most off-road obstacles.

However, the tyres on this vehicle (Giti Xross HT71 SUV - 265/60R18) aren't up to scratch when it comes to off-roading beyond anything other than well-maintained tracks in the dry. The Tank 500 as is well suited, straight out of the dealership, for light to moderate off-roading. But if you swap in a decent set of aggressive all-terrain tyres the Tank 500 will be able to more comfortably take on more challenging terrain.

But it's capable of climbing. I took on a 30-35 degree incline of rock steps and the Tank 500 did it easily and comfortably on its standard highway tyres.

Most of the plug-in hybrid Tank’s off-roading characteristics check out. Approach, ramp over and departure angles are as per the regular hybrid Tank 500 (30, 22.5 and 24 degrees) and wading depth is a listed 800mm although the country was so dry at our proving ground that I never had the chance to test that claim.

Ground clearance on the Tank 500 Hi4-T PHEV is listed as 213mm (it’s 224mm in the normal hybrid) but that doesn't negatively impact this vehicle's off-roading capability if you drive it with control and consideration.

It is big, so it can be a little bit tricky to steer around, especially when the track becomes tighter and the obstacles become a bit more cheeky, but generally this can be driven very safely and with the utmost control through a lot of tricky four-wheel driving challenges.

It's not as polished in its off-road performance as something like the Toyota Prado or Ford Everest, but it does the job and there's a bit of a gruff edge to it, which some people might consider part of its charm.

As mentioned, the Tank 500’s 37.11kWh battery supports Vehicle-to-Load (V2L) functionality, which in theory means you’ll be able to power your camp-site (lights, fridge etc), but I’ll reserve final judgement on this set-up until I have the opportunity to test it over a long weekend with several appliances drawing power at the same time.

If you’re thinking about using this Tank PHEV as an adventure touring vehicle then it’s handy to know its payload is listed as 610kg, while it’s noted as 790kg in the Tank 500 HEV. Throw two adults, two teenagers, a dog, and camping gear in and you’ll hit that 610kg mark in no time.

The Tank 500 is rated to tow a 750kg unbraked trailer and 3000kg braked. Gross vehicle mass is 3430kg and gross combined mass is 6430kg.

First things first, don't get too distracted by the word "performance" here. The IM6 doesn't act like a performance car, it feels bit too plush, and bit too digital, for that.

But that's not necessarily a bad thing. Performance cars are often loud, raucous and uncomfortable, and the IM6 is none of those things. Instead, those mountains of power and torque make silky, silent progress absolutely effortless, which feels pretty premium to me.

MG makes a big deal of how much work went into insulating the cabin from noise – with active noise cancellation joined by double-paned insulated glass – and it is a properly calming and quiet space.

Also strong is the suspension, with the adaptive air setup soaking up most bumps and bruises, but I found it can clang over really solid bumps, sounding like it's bouncing off a stopper. The steering is solid, too, with a nice weight, if not overly talkative in the feedback department, while the rear-wheel steering helps eat into the turning circle for tight three-point turns.

The downside, though, is that it all feels a little too digital, and like there's been a little too much overthinking gone into it. Having to push a button to see behind you in a hurry is bonkers (see my explanation in the Safety section below), and the secondary screen is more annoying than intuitive. And there were several bings or bongs I couldn't even identify. All of which interrupts the otherwise calming nature of the drive experience.

There is a long list of safety aids on the IM6, and I won't detail the lot here. But I will call out a couple of curious mentions.

As always, the driver distraction warning is annoying, but can be switched off. And MG also counts the IM platform, or what it calls a digital chassis, as part of the safety offering. It has its own digital brain that adapts the air suspension, the rear-wheel steering and the active safety kit on the fly.

The other curiosity is the weird way you see out the back. Rather than fit a digital rear-view mirror to counteract the almost non-existent rear vision, you instead push up on a little toggle on the steering wheel to bring up a live view of what's happening behind you on the central screen.
