What's the difference?
Anyone unfortunate enough to hear me banging on about electric cars - or perhaps more accurately, electrified cars - will be aware of my undying love for the existence of plug-in hybrid electric vehicles (PHEVs).
I love them because they offer a drama-free step into electrification. You don't need a big box on the wall to make sure you're charged overnight and because there's a petrol engine under the bonnet, as long as you've got fuel in the tank, your range anxiety disappears.
You can get around town in electrified silence and emissions-free smugness while still planning that around-Australia trip you'll never go on. It's absolutely the best of both worlds for those reluctant to take the next step. A genuine win-win, if you like.
Except that very few people buy them. Their existence in the catalogues of a number of car companies feels like a weary, "We should at least do something" from product planners. BMW has been trying with PHEVs for a while, with selected offerings in the 3, 5 and X5 range. Given the 5 Series has had its mid-life facelift, what BMW calls the LCI, it's time for another look.
The arrival of the GWM Tank 500 Ultra PHEV is noteworthy because it’s the first plug-in hybrid Tank model in Australia.
It’s also a major event for the Aussie adventure-travel community because it’s a plug-in hybrid 4WD with five seats, high- and low-range gearing, and a front, centre and rear diff lock.
The Tank 500 PHEV gets more power and torque than its hybrid stablemate, offers about 120km electric-only driving range (listed), and it can be used as a 6kW mobile power station (V2L) at your campsite. Towing remains at 3000kg.
There’s a lot in this Tank’s favour: it’s a body-on-ladder-frame chassis large 4WD with a packed standard features list and real off-road adventure potential.
All of that – and more – for under $80 grand.
But does the plug-in set-up add anything substantial in terms of daily driveability or does it simply make this Tank an $80,000 camp-site generator?
Read on.
The G30 5 Series is an excellent car and unless you're looking for the serious punch of the V8 M550i, or want to run with the cops in the diesel, the 530e is a great option. No slower than the 530i, well-equipped and that rarest of things, a truly elegant BMW. Nobody buys a BMW with an eye on the budget, so at this level, the $3000 gap is nothing to worry too much about. For EV-sceptics, the range anxious or just for someone who just can't take the full EV plunge now, a PHEV is a great bridge between the two worlds.
And if nothing else, it's not a giant SUV.
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.
The G30 5 Series dates back to a time when people thought the grille on this was A Bit Much. How wrong they were. The 5, like the 3, used to be part of a clutch of executive sedans that formed the backbone of the company's expansion and success from the 1980s onwards. That means the styling is never too adventurous and even Chris Bangle's E60 5 Series, while striking, was not particularly controversial.
The only problem with the G30 is that it's hard to distinguish from its predecessor, but that's not a real issue when you see how elegant this car is. Easy on the chrome, proportional grille, big wheels, it's a proper smooth operator, visually speaking.
The cabin is holding up nicely and fits with the rest of the BMW range. It's impeccably well built, full of nice materials and even the wood trim is all right. The black Nappa leather is quite lovely but I can't tell you what the standard stuff is like, so you'll have to work that one out for yourself. It's very calm in here, with a good balance of buttons and screens with which to operate the car and while it doesn't have the you-beaut wow of its E Class rival, with its two massive slabs of screen in front of you, it has plenty to offer.
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.
The 5 is almost five metres long, so as you might expect, it's big inside. Back-seat passengers have a ton of space to play with and even three across back there is doable for a distance. The outboard seats have some nice shapes to them, too, so they hold rear passengers in if the driver gets a bit ambitious. Loads of legroom, good headroom and very importantly, a good view out through the big side windows. Properly comfortable, then.
Front and rear passengers each score a pair of cupholders for a total of four as well as the same number of bottle holders. The centre-console bin is long and shallow, but does feature a USB-C port. The wireless-charging pad also has a USB-A port for those without the functionality and/or a phone too big to fit. Both the cupholders and charging pad have a sliding cover.
The boot is smaller than the standard car's as there is a lithium-ion battery hidden underneath the now-sloping floor. With 410 litres, it's smaller than a 3 Series' but it doesn't look that small. There is also a spot for the charging cable and its bag behind the left wheel arch.
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 530e sits almost smack-bang in the middle of a still reasonably extensive 5 Series range. While you can have an "entry" level 520i for $99,900 (before on-roads), the 530e lands at $122,900 (before on roads), which itself is $3000 more than the 530i, and the same amount less than the NSW cops' favourite, the 530d.
Given the price, you'd expect some gear and boy howdy does BMW deliver. You get 19-inch alloys, a 16-speaker stereo, multi-zone climate control, ambient LED lighting, reversing camera to go with the front and side cameras, keyless entry and start, electronic dampers, active cruise control, electric and heated front seats, sat nav, auto LED headlights, heat-insulated glass, head-up display, a mostly real leather interior, auto parking, auto wipers, digital dashboard, wireless charging and run-flat tyres.
The huge touchscreen on the dash runs BMW OS7, which accepts inputs via touch, the console-mounted rotary dial and (optional) various hand wavey-movements. The speakers have harmon/kardon badges on them and there is DAB digital radio and wireless connectivity for both Apple CarPlay and Android Auto.
In something of a classic BMW own-goal, the wireless charge pad that is designed to keep your phone snug is too snug for bigger phones like my over-compensatory iPhone. Even with the cover off, it just won't fit. Thankfully there's also a USB-C port in the centre-console bin.
The 520e I had for the week also had the $5900 Enhance package (20-inch M alloy wheels, glass sunroof and the excellent BMW Laserlight headlights), $2300 Nappa Black leather package, comfort front seats ($500) and a built-in dash cam ($390) called BMW Drive Recorder. This brought the price up to $131,990 before on-roads. Just so you know, the Laserlights are $2400 on their own.
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 530e comes with a 2.0-litre four-cylinder turbocharged engine developing 135kW and 290Nm, with the eight-speed ZF automatic sending power to the rear wheels. The electric motor spins up 83kW and 230Nm, also driving the rear wheels. When everything is working together, the combined output is 185kW and 420Nm, which delivers a quick 6.1-second dash to 100km/h, which isn't mucking about.
You can choose four drive modes. EV will (mostly) drain the battery, Hybrid will keep the two working together and Sport will deliver the most power. And drain the battery, albeit more slowly. Adaptive works the averages and decides what you need or want by how frisky you're being with your driving style.
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.
The 12kWh battery takes up the same amount of space as the old one, but has more capacity, extending its EV range. The claimed EV range is 57km on the WLTP standard.
The iDrive system has a bunch of settings that you can play with to squeeze more out of the silent-running mode and there's also a battery-charging mode button to force the ICE to charge the battery while you're on the move. Also useful is a timing system, so you can schedule when the car charges to take advantage of the cheap power available in the dead of night.
Recharging is easy but sadly a bit slow off a domestic power point. Having said that, if you plug it in after a day's commuting, you'll be topped up to 100 percent overnight. It's a long charge, but it's not as if you'll be stranded if you forget. You can get a wallbox, but there's not much point.
The fuel tank is just 46 litres. The WLTP combined cycle figure is a laughable 2.3L/100km. On that official figure, you'll cover an unlikely 2000km. My week with the car, which included 70km on EV-only power with one charge off my solar panels, got me an indicated 6.1L/100km in a mostly suburban week of driving. So based off that, you'll get about 530km from one full charge and a full tank, which is a bit confusing. Keep charging and, if you're an average Australian who travels little more than 30km per day, you won't use much petrol at all.
Having said all of that, out on the freeway, you'll probably slide towards that 2.3L/100km and make it from Sydney and Melbourne on a single tank. Just.
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.
The reason I like PHEVs as a tool for pushing people towards electrification is about more than the fact that it will likely cure buyers of range anxiety once they're realistic about their actual car usage. I mean it does do that, but it's more about the fact that PHEVs drive like a normal car, with few exceptions.
In EV mode, the acceleration is swift but not that brutal, YouTuber-friendly thrust EV fanboys use as proof that legacy car makers are dead. It's all very serene and very, very quiet as you move from traffic light to traffic light in near silence, while more than keeping up with traffic. The blue of the dashboard indicates your progress and the iDrive screen can keep you updated with power consumption.
The switch between EV and ICE propulsion is very smooth and it's almost like BMW has been doing this forever. You'll also discover an appreciable lift in performance, more in line with the M Sport badges. BMW's engineers have done nothing to make the 2.0-litre petrol sound better than a whirring mixmaster, though.
Slightly less M Sport-ey is the suspension. While there's absolutely nothing wrong with it, the adaptive dampers never dial things up too much for the average motorist. Granted the 5 will leave just about anything this size for dead as far as driver involvement goes, but it certainly keeps the dial closer to comfort than, say, the M550i does. Once again, it's a serene thing to get around in and passengers will love the quietness and easy flow of conversation. Or the lovely sound from the harmon kardon speakers.
You don't have to try too hard to cover a good chunk of the claimed 57km of EV range. Realistically you'll get close to 45km, even after my colleague Matt Campbell drained 20km of charge in a six-kilometre trip that he maintains was driven gently (snigger) and normally (guffaw). Without trying too hard, I managed 41km in pure EV after his attempts to ruin my numbers (not really, but I do enjoy the amusing false narrative).
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 big price tag buys you a comprehensive safety package. It has seven airbags, ABS, stability and traction controls, blind-spot monitoring, active lane-departure warning, forward AEB, reversing AEB, forward collision warning, front cross traffic alert, reverse cross traffic alert, lane-keep assist, pedestrian alert in EV mode and tyre-pressure sensors.
The forward AEB works at high and low speeds. The pedestrian detection works at urban speeds and there does not appear to be cyclist detection.
There are also two ISOFIX and three top-tether anchors.
The 5 Series was last tested in 2017 and was awarded five ANCAP stars.
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.
BMW really needs to up its game, as do Audi and Porsche (among others). Munich is still sticking with a three-year/unlimited-kilometre warranty while German rival Mercedes is up at five years and Japanese competitor Lexus four. You do get three years roadside assist thrown in.
All 5 Series (excluding M5) are eligible for service plans. For $1950, you're covered for five years/80,000km of servicing. As with most BMWs, servicing is based on how you drive but really, if we're being honest, the car will get you into the dealer once every 12 months or 15,000km. Roughly.
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.
