Jaecoo J7 vs GWM Tank 300

What's the difference?

The Jaecoo J7 SHS Track enters the medium SUV segment with a sharp drive-away price and generous equipment list. The ongoing ownership benefits add strong value but the on-road driving experience needs some finessing and the cabin doesn't quite hit every mark for practicality. Although it's ‘on track’ to make waves in this corner of the market, it hasn't yet carved out an iron-clad niche for itself. It's worth a look but it's not class-leading.

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.

The J7 is, in essence, a scaled-up version of its smaller sibling, the J5 - a car my family affectionately dubbed the “Temu Range Rover” during our week with it. The resemblance remains.

The squared-off proportions, upright grille and slim lighting signatures lean heavily into that premium off-roader aesthetic, and there’s no doubt the look will appeal to buyers chasing presence without the associated price tag.

Compared to the J5, the J7 carries a touch more personality. 

There’s a small racing-flag accent panel along the flanks, flush-fitting door handles and a set of 19-inch aerodynamic alloy wheels that add some visual flair.

Inside, the cabin is cleanly executed with its pared-back styling and the 13.2-inch central display dominates the dashboard. This makes it the visual anchor of the interior as physical buttons are minimal and most functions are accessed via the media screen. That screen-led design will divide opinion, but it does create a modern aesthetic.

The synthetic leather upholstery feels convincingly premium, and the materials do enough to lift the ambience beyond what you might expect at this price point.

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.

Up front, the J7 Track delivers where it matters. The electric front seats offer heating and ventilation functions and feel supportive over longer drives. There’s enough width and shoulder room to avoid feeling hemmed in.

Access is good with wide door apertures and an easy step-in, step-out height from both rows. In the rear, the available space is generous, and the thick seat padding and supportive backrests will make longer journeys quite comfortable. The flat floor also means the middle seat isn’t automatically the punishment position for an adult.

Storage has been thoughtfully considered. Up front, the large centre console shelves make it easy to keep clutter contained, while the dual-opening middle console is deep enough to swallow a small handbag. There’s also a small side pocket beside the driver that’s ideal for keys or a garage remote.

Rear passengers will enjoy four device pockets, as well as a couple of map pockets. There are two cupholders and drink bottle holders in each row, as well as good-sized bins in each door.

With all rows in use, the boot has up to 500L of capacity, and the flat loading floor makes it easy to slide larger items in and out. Overall, it’s a usable and practical space for gear storage but you'll notice the lack of a powered tailgate as there isn't a dedicated handhold on the outside of the lid to easily open the boot.

There's also no charging ports or power outlets in the boot, which feels unusual for a plug-in hybrid. You have to make do with a tyre repair kit rather than a spare wheel but that's not unusual in this corner of the market.

The individual charging options are functional with a single USB-A and C port offered in each row and a 12-volt socket up front but you miss out on a wireless charging pad in this grade. The multimedia touchscreen is responsive and the layout is fairly intuitive to use. However, the lack of physical controls for simple adjustments like side mirror positioning or climate control can become frustrating. Some functions are just better served by buttons.

The wireless Apple CarPlay and Android Auto operate smoothly and the CarPlay has maintained a steady connection this week. The built-in sat nav is also easy enough to use.

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.

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.

Both plug-in hybrid grades of the J7 share the same powertrain, pairing a 1.5-litre four-cylinder turbo-petrol engine with a single electric motor. Combined outputs sit at a healthy 255kW and 525Nm which is the same as its Chery cousin and makes it more powerful than its MG rival but the GWM Haval H6 GT has bigger outputs.

However, once the EV battery is depleted and the system leans more heavily on the petrol engine, the outputs drop significantly to 105kW and 215Nm. This shifts the J7 from feeling spritely to serviceable on the open road.

Power is sent exclusively to the front wheels, and towing capacity is rated at 750kg unbraked. That’s enough for a small box trailer but it won’t be hauling any serious weekend toys.

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 J7 Track has a Type 2 CCS charging port and accepts up to 6.6kW on AC power and up to 40kW on fast DC power. On that type of DC charger you can go from 30 - 80 per cent in as little as 20 minutes which is great for when you’re on the go. You can shop and charge without much fuss.

The 18.3kWh lithium-iron phosphate battery supports an electric-only driving range of up 90km (WLTP). That sits below its Haval and MG rivals with their respective WLTP ranges of 153km and 120km. Overall though, the J7 has a theoretical driving range over around 1200km, which is great. Of course, you will only see that type of range if you regularly charge it.

Jaecoo claims a combined fuel cycle usage (urban/extra-urban) of 1.0L/100km but my real-world usage has come out at 5.0L/100km even after regularly charging it. However, it's worth noting that I do a lot of longer, highway driving which is where plug-in hybrids are typically less efficient.

Jaecoo recommends a minimum 91 RON unleaded petrol to be used for the J7.

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.

This is where the J7 Track feels less resolved. It's not fundamentally flawed by any means but it's not as polished as it could be.

With a charged battery, acceleration is strong and immediate, and there’s enough punch for hills and confident overtaking. Even when the battery is running low, the drop in output doesn’t feel as dramatic in real-world conditions as the standalone engine figures might suggest. You won't win any drag races but it remains competent. It just loses some of the initial punch when accelerating.

Steering is light, which makes urban manoeuvring easy, and the suspension leans toward the softer side. Around town, that translates to a comfortable and compliant ride. Push it harder through bends, though, and the body control starts to feel a little loose.

Highway refinement is another area where there’s room for improvement. Road noise becomes noticeably more present at open-road speeds, although it remains quiet around town.

Visibility out the front and sides is good, and the driving position gives you a fairly commanding view of the road. I don’t feel like there are any large blind spots from my driving position.

There are three levels of regenerative braking, and running it in the strongest setting does a good job of harvesting energy. However, even on the lowest setting, the braking response feels abrupt. At low speeds when the system tends to remain in EV mode, the transition can feel lurchy.

The 360-degree camera system is clear and outside of the heavy-handed regen braking, the J7 is straightforward to park. Just be prepared for passengers, especially opinionated children, to comment on the body movement.

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.

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 Chinese lucky number '8' is heavily featured in the ownership as the J7 is offered with an eight-year/unlimited km warranty, eight years of battery cover and roadside assistance, plus eight years of capped-price servicing where services average just $422 per visit. That's an impressive suite of terms for the class.

Servicing is well-spaced at every 12 months or 15,000 kilometres and for now the service network is still fairly small, with around 50 centres nationwide.

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.
