What's the difference?
GWM’s Tank 300 struck a chord with Australian buyers when it launched in 2023. The rugged, boxy design, serious off-roading ability and unbeatable value for money - especially compared with similar models like the Jeep Wrangler - won it a number of new fans.
But something was missing. With an uninspiring petrol engine and a patchy hybrid powertrain the only options, the Tank 300 was sorely missing a diesel.
GWM itself says about 75 per cent of models in the off-road-focused large and upper-large SUV segments are made up of diesel-powered SUVs, so it was missing out on a chunk of sales.
Thanks to some serious nudging from GWM Australia and New Zealand, the Chinese parent company saw the potential and have added a diesel engine to the mix. This is the same diesel unit found in the GWM Cannon and Cannon Alpha utes.
Is the diesel now the pick of the Tank 300 range? Or should you look at another oil-burning 4x4?
Maligned by motoring journalists and car enthusiasts alike, the MG3 proved once again that critical success isn't necessary to be a best seller. As they say, there's no such thing as bad press.
The small car was the SAIC-owned MG brand's Hyundai Excel moment. The 2011 MG3 became a price leader that put the brand on the map in Australia finding plenty of homes with first car buyers and rental fleet managers alike.
Here’s a stat that might surprise you: over 15,000 of the small cars sold locally - almost four times as many MG3s found homes in Australia last year than in the much larger UK market.
The new 2024 MG3 is looking to build on that success and follow in the footsteps of the critically acclaimed MG4 electric car which is selling strongly.
This third-gen MG3 (not everyone knows about the Rover Streetwise-based MG3 SW sold in China) brings a fresh platform, updated safety features and even a fuel-sipping hybrid powertrain.
All things that should help it steal sales from now rather expensive rivals, including the Toyota Yaris, Mazda 2, Suzuki Swift and even Volkswagen Polo, if it’s good enough.
For all the new MG3's added features and striking looks, it's a nameplate that predominantly sold on price and value over buyer interest. We've driven the entry-level Excite trim fitted with the 'Hybrid+' powertrain to see if the makeover has been a success.
The diesel is now the pick of the Tank 300 range. It’s the best fit for this vehicle and offers greater driver engagement than the petrol or hybrid.
It also has genuine off-road chops while still managing to suit family life.
While it could benefit from further refinements to on-road behaviour, cabin noise and the ADAS systems, none of these are deal breakers.
The fact that it is priced so keenly against some excellent competitors and is stacked with standard gear adds to the Tank 300’s appeal.
Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.
There is no doubt that the new MG3 is better than the car it supersedes – that tends to happen when you replace something that's 13-years old. It drives smoothly enough, has a frugal hybrid powertrain and good levels of safety equipment. Interior space is adequate and there are some genuinely nice touches like the comfortable seats and cabin design.
But that doesn't mean the new MG3 is better than the Toyota Yaris, Mazda2, Suzuki Swift or Volkswagen Polo. Those established rivals are more consistent, have greater breadth of ability and now really aren't that much dearer than MG's entry-level city car.
That said, the MG3 is still more affordable than most and transformed in driving experience. It is, therefore, worth putting on your small car short list, if no longer buy-without-thinking cheap. We applaud MG improving its products based on feedback and hope the much-improved MG3 finds buyers. Expect a comparison test with key rivals soon for a definitive verdict.
The only visible difference between the diesel and the petrol or hybrid 300s is a 2.4T badge. So you get the same boxy exterior as before.
It’s somewhat derivative and gives more than a nod to Jeep, but the design has intent - it looks capable off-road and for most people that’s enough. Luckily it is capable off-road. More on that later.
Inside the upright, shelf-like dash is appealing. I like that everything is nicely integrated, like the dual 12.3-inch screens which flow nicely into one another.
The big T-shaped three-spoke steering wheel looks cool and the aeronautical air vents are clearly inspired by Mercedes-Benz.
The chunky metal-look plastic glove box cover adds extra visual flair and the stitching throughout elevates the cabin further.
However, the futuristic looking gear shifter is chunky, takes up too much space and is unnecessary.
For all the flack Chinese carmakers have taken for copying others homework, the new MG3 is refreshingly original from the outside.
Not to say it's a beautiful car: that front overhang is a little too long and we think the wheel design is a little chintzy but at least the new MG3 feels differentiated in the class.
It has a distinctive face and confident character lines down its flanks while the Brighton blue hero colour (pictured) is eye-catching – we'd skip the '90s inspired Pastel yellow hue, though.
Inside, a hexagonal steering wheel borrowed from the MG4 is complemented by confident horizontal volumes. The MG3's interior is largely uncluttered by buttons and, in a nod to the previous MG3, there's an off-axis Tartan flourish ahead of driver and passenger.
MG has placed a piece of soft vinyl prominently, situated just in front of the high resolution 10.25-inch touchscreen to give the cabin a tactility lift. The rest of the materials are typically plasticky yet there is a pleasant grain that takes some of the shine away and restore a more quality feel.
Up front the Tank 300 offers a commanding view of the road and it’s easy to find your perfect driving position thanks to the power-adjustable seats.
Those seats have good side bolstering but could do with a little extra cushioning for the thighs. The Nappa leather-appointed seats in the Ultra look and feel lovely.
Storage is average for the segment with room for larger bottles and additional flat items in the door pockets, and a well-sized central bin that also houses two cupholders, although they sit low in the cavity and two coffees sit awkwardly together.
The Tank has one USB-C port for charging only but another USB-A port up front for connectivity. You shouldn’t need that given Apple CarPlay and Android Auto is wireless.
Keen off-roaders will have fun with the extensive Tank Expert Mode in the multimedia screen, which allows you to individualise your 4WD experience.
Beyond that the screen is neatly laid out, responsive and easy to use. GWM has come a long way when it comes to in-car tech. The icons on the digital instrument cluster, however, are still too small.
There’s ample leg room in the rear, with space between my knees (I am 184cm tall) and the rear of the front seat, and enough toe room. It doesn’t feel enormously spacious across the rear row but three kids should be comfy. Headroom is enhanced by a scalloped section of the roof specifically for rear-seat passengers, but it doesn’t leave a huge amount of space for taller people.
The rear seat bench is flat but the backrests have some support and overall the seats back there are comfortable.
You’ll find lower rear-seat air vents, map pockets, a fold-down central arm rest with two cupholders, room for small bottles in the doors and two USB-A ports.
The boot can take 400 litres with all seats up and 1635L with the rear seats folded. That figure is measured from the floor to the top of the rear seats.
Jeep says the Wrangler has 898L capacity with all seats in place but that is measured from the floor to the roofline.
There is no under-floor storage in the 300’s boot and the full-size spare wheel is housed in traditional 4x4 fashion on the tailgate.
The brand has clearly worked on the functionality of its multimedia system since debuting in the MG4. It looks familiar but the touchscreen is more responsive and there are intuitive shortcut buttons for the screen-based HVAC controls.
Apple CarPlay and Android Auto remains wired via a regular USB port, unfortunately, and there is no wireless charging on either grade. A USB-C port and 12-volt socket are present for extra cabled charging.
The digital driver's display has adequate functionality and includes an instant tyre pressure monitoring display – a key safety feature.
The steering wheel controls have been updated with clearer labelling. The right side controls the media volume and driver's display and left panel manages cruise control and driver assistance features.
MG's Excite doesn't feel like a de-contented base model with quite agreeable cloth upholstery, The driver's seat offers six-way manual adjustment and is comfortable with good back support.
The driving position was good for me, however, without telescopic steering wheel adjust you may find it more difficult to find an ideal spot.
There are two cup holders in the centre console ahead of the rotary gear selector (base petrols get a normal shifter). A further tray for phone and wallet storage sits ahead and the door bins are generous for a small car.
Not to be taken for granted in the class is a padded centre armrest with covered storage for valuables.
Measuring just over 4.1 metres long, don't expect palatial back seat space but the MG3 is certainly passable for a city car. At 188cm I could just squeeze in behind my driving position and soft-backed chairs aid comfort.
There are even adjustable vents and a USB port for rear passengers. Unfortunately, the window switches are not all auto up and down.
The standard trio of top tether anchors and pair of ISOFIX anchors for outboard seats are present for child capsules and chairs.
It's in the boot where the MG3's cost cutting becomes most obvious. The floor material is flimsy, there's only one shopping back hook and the back rest is a rare case of non split-folding. It is an awkward task flicking the seat down as you need two hands to unlatch the rest.
At 293 litres the boot is generous in size, though, and petrol models feature a space-saver spare. The hybrid places its 12-volt battery in the cavity under the floor.
One of the key selling points across GWM’s entire range is value for money, and the Tank 300 has always had that in spades.
As with the petrol and hybrid 300, the diesel is offered in two well-specified model grades - Lux and Ultra.
At $47,990 drive-away, the Lux diesel is $2000 more than the Lux petrol, but $3000 cheaper than the Lux hybrid.
The Ultra diesel, at $51,990, is $1000 pricier than the petrol equivalent and $5000 more affordable than the hybrid Ultra.
The GWM Tank 300 diesel Lux is also more affordable than equivalent grades of a number of ladder-frame 4x4 SUV rivals like the Isuzu MU-X, Toyota Fortuner, SsangYong Rexton and the Ford Everest.
It’s also significantly more affordable than the Jeep Wrangler, with the Tank 300 Lux costing about $30,000 less than a Wrangler Unlimited Sport S.
Note however that many of those models - except the Wrangler - have the option of seven seats, whereas the Tank is strictly a five-seat proposition. If you want a third row, check out GWM’s Tank 500.
There are cheaper off-road large SUVs out there – the LDV D90 and Mahindra Scorpio. But the Tank 300 is a more refined and higher-quality offering than those models.
Standard gear in the Lux includes 17-inch alloy wheels, synthetic leather seats and steering wheel, power-adjustable front seats, dual-zone climate control, seven-colour ambient lighting, keyless entry and start, a sunroof, power-folding mirrors, paddle-shifters, a nine-speaker audio system with digital radio, built-in sat-nav, and a pair of 12.3 inch digital displays with wireless Apple CarPlay and Android Auto.
It also gets roof rails, side steps, privacy glass, all-terrain mode selection and a rear diff lock.
The Ultra upgrades to 18-inch wheels, Nappa leather-accented seats, heated and ventilated front seats, a heated steering wheel, more adjustment for the front seats and a memory setting, a massage function for the driver’s seat, a wireless phone charger, 64 colours in the ambient lighting suite, and a nine-speaker premium audio system.
There is nothing obvious missing from the standard features list, but I don’t know why a wireless device charger is limited to the top grade.
MG offers two trims – Excite entry level and Essence range topper – and a pair of powertrains. They're difficult to tell apart in the flesh using the same exterior garnishes, matching mirror caps and identical wheels.
Start price is up a whole lot from the previous model and it is no longer drive-away. It pushes the current run-out $18,990 drive-away price up to $23,990 before on-road costs.
The Hybrid+ powertrain is an expensive option adding $4000 to the price.
You do get a lot more for your money, though. A set of 16-inch alloy wheels (no hubcaps here), a CVT automatic, a 10.25-inch touchscreen, a digital driver’s display, cloth upholstery, manual seat adjust and polyurethane-appointed steering wheel feature on the Excite.
Outside, you can only tell the difference between our base car and the $2000 more expensive Essence by the LED headlights and a sunroof, otherwise they’re visually very similar.
The Essence gets rain-sensing wipers, white artificial leather upholstery on the seats, leather-wrapped steering wheel, a 360-degree camera and remote smartphone control of the air conditioning and heating.
The Essence adds a few goodies but it's not a transformative jump. The Excite feels like all you need.
Growing more expensive than the Kia Picanto (GT-Line at $23,490 drive-away) is probably no bad thing either, as the Korean car is significantly smaller than the MG3. Pricing for the new Suzuki Swift is set to be revealed shortly, but it is likely to undercut the MG3, too.
The MG3's powerful hybrid allows it to compete with the Toyota Yaris Ascent Sport hybrid on more level terms... but it needs to because its price is only $501 shy of the Toyota.
The big news with the Tank 300 is, of course, the new engine.
It is a 2.4-litre four-cylinder turbocharged diesel engine borrowed from the GWM Cannon and Cannon Alpha utes.
It pumps out 135kW of power and 480Nm of torque. That’s more torque than an MU-X but not as much as an Everest.
It is paired with a nine-speed automatic transmission and has part-time four-wheel drive.
If you need to tow, the diesel has a 3000kg towing capacity, which is 500kg more than the hybrid and petrol. It can’t beat the 3.5-tonne towing capacity of the MU-X and the Everest.
Payload has also increased compared with the petrol and hybrid, up from 400kg to 600kg.
GWM says it conducted extensive testing internationally but also in Australia to improve towing performance. There are approximately 20 different parts compared with the other powertrain variants to get the best out of towing in the diesel.
A rear diff lock is standard on both grades while the Ultra gains a front diff lock.
The 1.5-litre petrol four-cylinder is a new direct-injected item that produces less power (81kW at 6000 rpm – down a kilowatt) and torque (142Nm at 4500 rpm lower by 8Nm) than the item it replaces.
It now drives the front wheels via a CVT automatic instead of a four-speed slushbox.
The 'Hybrid+' option is much more interesting. It uses a different 1.5-litre petrol engine running in Atkinson cycle and, unlike the Suzuki Swift, is a proper system.
MG's hybrid is different to Toyota's 'e-CVT' transaxle set up, the brand calls its transmission a three-speed automatic. We have not seen diagrams but in operation it feels similar to GWM Haval's 'Dedicated Hybrid Transmission' solution in the Jolion.
That means impressive peak outputs of 155kW and around 420Nm but those figures only occur at very specific times – peak torque, for example, is only delivered at 50km/h in second gear when the 1.83kWh battery is suitably charged.
The resulting 0-100km/h sprint claim is 8.0 seconds for the MG3 hybrid.
The diesel Tank 300 consumes 7.8 litres of fuel per 100 kilometres on the official combined cycle, which is better than the 9.5L figure for the petrol and the 8.4L quoted for the hybrid.
That figure also sits somewhere between a 2.0-litre bi-turbo Everest (7.1L/100km) and a 3.0L MU-X (8.3L/100km).
It has a 75-litre fuel tank and GWM claims an NEDC range of about 950 kilometres. GWM says the Euro 5 engine does not require Adblue.
Given the restrictions of a media launch, we did not obtain real-world fuel use figures.
The petrol-only model's rated fuel consumption falls from 6.7L/100km to 6.0L/100km. It requires 91 RON unleaded and is rated to Euro 5 standards.
The hybrid scores 4.3L/100km in the ADR combined consumption. That's not as good as a Toyota Yaris hybrid (3.3L/100km) but the trade-off is way more grunt.
From the 36L fuel tank – that requires 95 RON unleaded – you can expect over 1000km total driving range.
In reality, we managed to come close to the figure on a 200km country and suburban loop with the trip computer reading 4.8L/100km. A 50km suburban commute was better returning 3.4L/100km.
The MG3's hybrid system can be a little fickle, though.
For the first 10 minutes of driving the petrol engine has to rev at 1500-2000rpm to charge the battery. We saw consumption climb to 10L/100km when the car was cold.
It also proved more sensitive to driving style than Toyota's hybrids which seem to be extremely efficient no matter how heavy your right foot is.
I last drove a Tank 300 in late 2023 and it was the hybrid variant. While the hybrid has some positives, its driving characteristics were not high on that list.
It had an erratic throttle response, hesitation on take-off and it felt underdone.
In contrast, this new diesel variant just feels like the right fit for this SUV.
There is slight lag accelerating from a standing start, but the powertrain is torquey and there’s plenty on tap when overtaking or just increasing speed when already on the go. GWM has not provided a 0-100km/h time.
It is clear you’re in a diesel as soon as you turn on the ignition - it has that typical diesel rattle, but it is not as unsophisticated as some oil-burners I have driven.
The cabin could do with some extra insulation with wind and tyre noise detected, but it’s hardly a deal breaker.
Given the vehicle’s size, heft (nearly 2.3-tonne kerb weight) and the fact it’s shaped like a brick, the 300 holds its nerve on winding stretches of road with only a little body roll. In saying that, best not to treat it like a Mini Cooper on your favourite twisty road.
Ride quality is a bit mixed. We only drove the Ultra on 18-inch wheels and while it manages to soak up bumps, the ride is jittery, and that’s even more evident on uneven road surfaces.
Steering is heavily weighted and a little vague, but fine for a big off-roader, and the brakes need to be pushed hard.
One quirk is the indicator - it appears to be a one-touch setup for indicating to change lanes, but then the indicator stays on. I tried several times to test this, even flicking it to the opposite side to turn it off and it was very stubborn.
The good news is it appears GWM has toned down the awful indicator sound of its earlier models and is now much more subtle.
So on-road the Tank 300 is more than competent, and a much nicer vehicle to drive in an urban setting than a Jeep Wrangler, for example.
We also drove it briefly on an off-road trail, and in low range the Tank 300 proved that it can do what it says on the box.
I’m no off-roading expert and there are much more challenging trails out there, but I had confidence that the Tank 300 would not let me down traversing the many chunky rocks, massive holes and fallen tree limbs.
The MG3 continues the theme on the road. An impressive effort at first glance – certainly enough to impress on a test drive – yet spend an extended period behind the wheel and some cracks begin to show.
The steering is light and easy in town with two and a half turns lock-to-lock and a tight turning circle. There is good visibility out and driver aids are mostly unobtrusive.
Borrowing from its EV stablemates, the MG3 has three levels of regenerative braking. It defaults to '2', the mid setting, which we found a bit too bitey – '3' is way too much. The lowest level is relatively natural, though no setting is a one-pedal mode.
Its ride is really good for the class being more compliant than a Kia Picanto. The front end is especially absorbent though the rear can be a little abrupt on sharp bumps – this is common on small cars with front struts and rear torsion beams.
The MG3's hybrid powertrain is smooth and slick around in the city with a reassuring brake pedal.
And while the torque figure doesn't always ring true when the battery is discharged, with it juiced up the MG3 is rapid between 35-60km/h. The fairly light 1298kg kerb weight keeps it feeling quite peppy.
Not all is perfect, though, and the MG3 isn't so talented on the open road.
This little car is very noisy on coarse chip road surfaces at above 70km/h and there are pronounced steps in the power delivery at higher speeds, making it hard to trust the MG3 when merging into gaps.
Be wary of the speedometer as well – it is more accurate than most cars with almost no error. Our GPS lined up exactly at 100km/h.
The MG3's steering has poor on-centre feel at pace. There is a lot of body lean to the chassis and it reacts nervously to small corrective inputs in crosswinds and cambers.
Wrapped around its 16-inch alloys are 195/55 R16 sized Kumho Solus HS63 tyres which are reasonable but nothing special.
A brief test drive could convince you the MG3 has moved ahead of the Suzuki Swift, Mazda2 and even Volkswagen Polo. A longer drive confirms that, though the MG3 has come a long way, the more expensive nameplates in the class are more polished all-rounders.
ANCAP awarded the Tank 300 a five-star crash safety rating from testing done in 2022, scoring highly across all four of the major test categories.
GWM says it is waiting to hear from ANCAP but expects the diesel to be covered by the same rating.
As well as seven airbags including a front centre bag, the Tank 300 has a long list of safety gear covering both the Lux and Ultra.
There’s a suite of collision mitigation systems that includes auto emergency braking (AEB), lane departure warning, lane-keep assist, emergency lane keep, lane centring, front and rear collision warning, front and rear cross-traffic alert and lane change assist.
It also has driver fatigue monitoring, a rear seat child monitor, door opening warning, adaptive cruise, traffic sign recognition and hill-descent control.
I noted this in my recent GWM Haval H6 GT PHEV review, but GWM has made consistent tweaks to improve its advanced driver-assist systems (ADAS) and as a result they are less intrusive than they were when the Tank 300 launched in 2023.
There is still the occasional tugging of the wheel but it’s much less of a tug-of-war than it once was.
For the first 45 minutes of our test drive there was an annoying beep every 10 seconds that my co-driver and I could not identify. There was no icon on the driver display to indicate that it was a lane departure warning or speed limit alert, but eventually it just stopped. We still have no idea what it was but it was, thankfully, not present in the vehicle we drove in the second half of the launch drive.
The MG3 has yet to be rated by independent safety testing bodies, including ANCAP.
The MG3 follows the MG5 sedan which was awarded a zero-star rating by ANCAP. Not only did it lack safety features, it scored zero in various adult occupant protection criteria including frontal offset, full width, far-side and whiplash protection.
Unlike the 5 the MG3 is a key vehicle in Europe and the United Kingdom so a high rating in crash testing is important.
All MG3s are fitted with adaptive cruise control, autonomous emergency braking, speed sign detection, lane-keep assist and lane-departure warning. The Essence gets blind-spot detection and rear cross-traffic alert on top.
The systems aren't intrusive in town but the lane-trace assist and adaptive cruise control are not great. The lane-assist bounces the MG3 between lane markings and the adaptive cruise slows down too early and quickly when approaching another vehicle.
The MG3 features six airbags: front driver and passenger, curtain and side though there is no centre airbag.
GWM covers the Tank 300 with its seven-year/unlimited-kilometre new-vehicle warranty, which is an impressive offer.
You are covered for seven years of roadside assist and the Tank is offered with a seven-year capped-price servicing program.
GWM is yet to confirm the Tank 300 diesel’s servicing offer (including pricing), but expect a service schedule similar to the Cannon ute with the same powertrain.
That means the first service might be required at 5000km or six months and beyond that it will need a service every 12 months or 10,000km, whichever occurs first.
MG's seven-year/unlimited kilometre warranty is equal best-in-class with the Kia Picanto.
The brand has yet to detail service pricing and scheduling for the new light car.
