BMW X7 vs GWM Tank 500

What's the difference?

When lined up against its direct rivals, the expensive X7 xDrive40d represents reasonable value for money.

It has a unique and bold look and a sumptuous, visually striking and well-appointed interior that has acres of space for family, friends, or for ferrying frequent flyers to the airport. 

That wallop of performance from the big beefy diesel is the cherry on the top. This is how you do a mid-life update. 

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.

There’s quite a bit that’s interesting about the X7’s design. Especially looking at it front on.

BMW certainly took a bold step when it introduced its toothy grille design for the X7 and the 4 Series range. 

But the Bavarian brand has made some even braver design moves recently by introducing a blocky front-end with split headlights on its new-gen 7 Series flagship sedan. That look has now found its way onto the face of the updated X7.

As with the 7 Series, it won’t be to everyone’s taste. But you can’t deny it has a lot of presence. 

The tail-lights have been tweaked and look good, but the sheer size of the X7 - it’s 5.2 metres long and 1.8 metres tall - means there’s no disguising the fact that it is a big, boxy SUV.

Inside the update ushers in significant design changes. The old dash and cowl is gone in favour of the ‘Curved Display’ that connects the instrument cluster and multimedia. 

New slimline air vents, LED backlit ‘X7’ graphics on the passenger side of the dash, and a new gear shift toggle that replaces the old shifter elevate the cabin and give it a much more modern vibe than the old X7 - one that’s in keeping with the excellent iX electric SUV.

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.

Regardless of the price point, a three-row SUV needs to be super practical and capable of family duties. 

And if you want a BMW X5 but need a lot more space, this is the next logical step.

Let’s start in the front row. As mentioned, the new X7 gains the screen and tech set-up from other new BMW models like the iX and updated 3 Series. The Curved Display combines a 12.3-inch digital instrument cluster with digital speedo and a 14.9-inch multimedia screen.

You can customise the cluster layout and move things around on the multimedia screen, too. The latter is a touchscreen but you can also find what you need via the 'iDrive' controller in the console.

I have had some experience with this system in the iX and while it’s not without its flaws, it is a top notch system. There’s a lot to wrap your head around, but the use of app icons helps. And you can swipe through to your chosen screen.

It took far too long to work out how to find the trip computer, something that should be much easier to access, as well as a couple of other functions. And the climate controls are housed in the digital screen. I would always prefer a separate space with buttons for air-con.  

But the graphics and displays - including the excellent head-up display - are excellent. 

Other tech you get with the X7 includes the BMW’s 'Digital Key', which is an app that allows iPhone users to lock and unlock their car remotely, and BMW ID driver profile.

If you buy this car, just allow yourself some time to familiarise yourself with all that tech.

Elsewhere up front there’s a lovely new three-spoke steering wheel, and cute touches like the metal air vent toggles, black and metal touches and the choice of inserts.

The front seats are luxurious and comfortable and offer loads of side and thigh support. They have memory functions, too. There’s no shortage of headroom up front, either.

Storage-wise, the door will fit the largest of bottles, as well as other items thanks to generous door bins, while the central lidded box is also sizeable. 

What about that second row?

The X7 xDrive40d usually comes standard with seven seats, but our test car was fitted with the $1500 captain’s chair option which drops seating capacity down to six people.

If you need the extra seating this is not the option for you, but it is great for families with bigger kids, and it would make for an excellent airport transfer car. 

The seats are unbelievably comfortable and can be adjusted to suit your preference. They also have ISOFIX points and armrests. 

Rear seat occupants have access to their own climate controls, air vents, USB ports, cupholders and ample door storage.

There is a massive amount of occupant space as well - stretch those legs out and enjoy it!

One of the X7’s selling points is that it is a genuine three-row SUV. That third row is not just for occasional use for very small children, like so many seven-seat SUVs. That row can be used every day. 

Even with my six foot stature, I could easily climb in and out of the third row. That’s made even easier thanks to the mechanical seat functions.

Just hit the lever at the top of the second row seat and the motor moves the seat forward and up to ensure there’s a big enough aperture to get in and out of the rear seats. 

You can also raise and lower the third row electronically via buttons on the boot wall - and they stow flush into the boot floor. Neat!

Once in the third row, there’s air vents, USB ports, bottle holders and storage and quite comfortable seats with more than enough leg and head room.

There’s even a third row section of the sunroof, operated from the second row. Lots of clever touches that people who use the third row will appreciate.

The boot has a few cool features, too, including a split tailgate.

You can even sit on the lower section - it can handle a load of up to 250kg - a perfect place to sit and watch the polo.

You can lower the suspension to aid loading larger items, and the X7 comes with a space-saver spare wheel.

Capacity is 300 litres with all seats in place, and I easily fit a pair of smaller suitcases in with that configuration. It increases to 2120L with the two rear rows folded. 

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 GWM Tank 500 PHEV is only available in high-spec Ultra trim and has a listed drive-away price of $78,990.

Standard features in the Ultra include a 14.6-inch multimedia touchscreen (with wireless Apple CarPlay and Android Auto), three-zone climate control, 18-inch alloy wheels, electric side steps, a 360-degree view monitor plus 'clear chassis view', auto parking assist, auto reversing assistance, lane departure warning and lane keep assist, all-terrain driving modes and an electronic rear diff lock.

Worth noting the Tank 500’s 37.11kWh battery supports Vehicle-to-Load (V2L) functionality, which means you can power your camping gear (lights, fridge etc). It offers up to 6.0kW of off-grid power, according to GWM.

'Marble White' paint is standard. Metallic paint, including 'Crystal Black' ($495), 'Dune Gold' ($595), and 'Onyx Silver' ($595) costs extra.

The X7 xDrive40d is powered by a 3.0-litre, in-line six-cylinder turbo-diesel engine, that gets a boost in power - it pumps out 259kW of power and 720Nm of torque - 64kW/100Nm more than the 30d.

It now also comes with 48-volt mild hybrid tech, which uses an electric motor integrated in the eight-speed automatic transmission.

It drives all four wheels via BMW’s 'xDrive' all-wheel drive system and it is fitted with air suspension for a cushy ride. Towing capacity is rated at 3.5 tonnes braked or 750kg unbraked.

If you are keen on off-roading in the X7, it has a 221mm ground clearance, and a fording depth of 500mm, but maybe best to keep it on the tarmac.

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.

According to BMW, the official combined cycle fuel figure for the X7 40d is 8.0 litres per 100 kilometres.

Our fuel figure after nearly a week of mixed city, freeway and country driving was 9.0L/100km, which isn’t too far off the mark.

It has an 80 litre fuel tank and an approximate driving range of 1000km.

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.

With a big plush SUV like this, you’d expect a comfortable ride. And for the most part, the X7 delivers that, while offering more than a bit of grunt, as well.

The X7’s height ensures a high driving position, and there’s plenty of glass for decent visibility. 

Propelling a 2.5-tonne SUV could be a struggle for a lesser engine, but the meaty diesel offers ample torque and the mild hybrid set-up helps to reduce initial turbo lag significantly - that means it is responsive from a standing start.

I wouldn't have thought a vehicle of this size and shape was capable of a 5.9-second 0-100km/h time, but here we are.

As a result of all that torque and power, overtaking is a breeze - providing there is enough room on the other side of the road for both cars to fit.

That size and heft have an impact on cornering and dynamics. You simply can’t carve through tight corners in this car, but with that said, it’s more entertaining than you’d think. 

Steering feel is weighted on the heavier side and it’s as sharp as it needs to be in a car like this. It would be weird if the steering was too pointy. 

Ride quality is top notch - as it should be - and while the massive optional 23-inch wheels and low profile tyres mean you’ll notice potholes and the like, it largely soaks up imperfections with ease.

That level of refinement extends to the hushed ride, too. The cabin is a quiet and serene place to spend time - but not quite to the same degree as a 7 Series. 

Parking in tight spots is a challenge, and manoeuvring in narrow streets could take a while, too. But you could tell that just by looking at the X7.

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.

The Tank 500 has the maximum five-star ANCAP rating from testing in 2024. As standard, it has seven airbags and a comprehensive suite of driver-assist tech including AEB, lane departure warning, adaptive cruise control, tyre pressure monitoring, front and rear parking sensors and a 360-degree around-view camera.

After copping a bit of flack from motoring media and buyers, BMW finally increased its warranty terms last year from three years to an industry standard five-year, unlimited kilometre warranty on its vehicles, including the X7.

Rather than a set servicing schedule, BMW offers condition-based servicing which is when the vehicle’s computer alerts the owner that it requires a service. 

BMW doesn’t offer capped-price servicing, but does have a pre-paid 'Service Inclusive Package' with terms ranging from three years/40,000km to five years/80,000km and beyond. 

A five-year basic package for the X7 costs $2800, which is not too bad considering the positioning of this model.

The Tank 500 is covered by a seven-year/unlimited km warranty, seven years' roadside assistance and seven years' capped price servicing.

The Tank 500’s 37.1kWh traction battery has an eight year/unlimited km warranty.

The first service is scheduled at 12 months/10,000km; the rest of the servicing appointments are set for every 12 months/15,000km. Lowest price per services is $335, highest is $975.

GWM has 122 dealerships nationwide at time of writing.
