Kia Sorento vs GWM Tank 300

What's the difference?

The Kia Sorento GT-Line PHEV is a sumptuously equipped seven-seater that delivers comfort, tech and an easy-going drive. It presents well on the surface, and for the right buyer (one who can make the most of its plug-in capabilities ) it could be a smart, low-emissions option for family life.

But for all its polish, it doesn’t quite do enough to justify itself as the best Sorento in the range. The electric-only driving range isn’t especially generous, and the higher price tag , combined with its lower towing capacity, may leave some families wondering whether the diesel variant is the more practical choice.

It’s not a bad car by any means, but the flagship GT-Line PHEV feels more like a stepping stone than a standout.

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 Sorento looks exactly how a modern SUV should - confident, capable, and well-proportioned without feeling bulky. It wears its size well, delivering that commanding presence families often want in a seven-seater, without coming across as too aggressive.

I especially like the 19-inch alloy wheels as they suit the vehicle’s stance perfectly. I also like the striking LED lighting signatures front and rear, which really come to life after dark.

Step inside and the cabin strikes a neat balance between tech-forward and user-friendly. You’re greeted by dual 12.3-inch widescreen displays that make a strong first impression, but thankfully Kia hasn’t gone all-digital! You still get physical buttons and dials where they matter, making everything feel intuitive and easy to navigate.

Material quality is a highlight. There’s quilted Nappa leather upholstery, soft-touch surfaces throughout, and even a luxe suede headliner. These premium touches, coupled with the panoramic sunroof, lift the ambience and it's a cabin that feels genuinely upmarket, but not at the cost of family friendly functionality.

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.

Space up front is generous, with excellent seat comfort thanks to wide seat bases, extendable under-thigh support and heating and ventilation. Getting in and out is easy, too, helped by wide door openings and a manageable 176mm ground clearance.

Storage throughout the cabin is thoughtful and abundant. Up front, there’s a large glovebox, a spacious centre console with a removable shelf, two cupholders, door bins with bottle holders, and a handy phone cubby beneath the dash.

The second row adds its own bottle holders and storage bins in each door, map pockets, four cupholders (including one cleverly placed on each door) and a removable floor shelf in front of the centre seat.

Even the third row isn’t forgotten, with a snack cubby and cupholder built into each wheel arch.

Tech-wise, the dual 12.3-inch displays look sharp, and the media system is intuitive and quick to respond. The instrument cluster isn’t particularly customisable, and I’m not a huge fan of the layout, but it displays the essentials clearly. You also get a head-up display, satellite navigation with over-the-air updates, and both wireless and wired Apple CarPlay and Android Auto.

Charging options are solid across all three rows, with multiple USB-C ports, a 12-volt socket in the second row and boot, and a wireless charging pad up front.

The second row offers ample legroom, though headroom is slightly reduced due to the panoramic sunroof. The lack of a transmission tunnel is a win for middle seat comfort, and the bench is wide enough to accommodate three child seats side-by-side. There are three top-tether points and ISOFIX anchors on the outboard seats.

Comfort and convenience features in the second row include heated outboard seats, device pockets, directional air vents, and the same handy storage and charging options mentioned earlier. My son especially loves the retractable sunblinds and the cupholders built into the door handles as they’re easy to reach and super practical. I am, however, disappointed that there’s no separate climate control zone for this row.

As for the third row, it’s best treated as a sometimes seat for adults. Access is more child-sized, and amenities are limited, but you do get directional air vents and a fan control, which are definitely appreciated.

Boot space is tight with all three rows in use, at just 175L, but that was still enough for the odd errand during the week. Fold the third row down and you get a much more usable 604L. Both rows fold completely flat, making it easy to slide in larger items, and the GT-Line includes a powered tailgate and a rare full-size spare wheel for extra convenience.

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.

Powering this GT-Line variant is a plug-in hybrid system that pairs a 1.6-litre turbocharged four-cylinder petrol engine with a small electric motor and battery. Combined, the system delivers up to 195kW of power and 350Nm of torque, which is plenty to get this sizeable SUV moving with confidence.

It’s a part-time all-wheel-drive set-up with a lock mode for extra traction when needed, and it’s paired with a smooth-shifting six-speed automatic transmission.

Around town and on the highway, the power delivery feels seamless and refined, with the electric motor doing a nice job of smoothing out stop-start driving.

One key trade-off, however, is towing capacity. While the diesel Sorento can tow up to 2000kg braked, the PHEV’s figure drops to just 1010kg. That’s a significant reduction and could be a deal-breaker for families who regularly tow a camper, trailer or boat.

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 Sorento GT-Line PHEV offers a WLTP-rated electric-only driving range of up to 57km - not huge, but enough to cover most daily commutes or school runs without dipping into the petrol tank.

When driven as intended and regularly charged, it’s capable of a combined fuel consumption figure as low as 1.6L/100km and this is paired with a 67-litre fuel tank. That means you could go a seriously long time between fill-ups if you’re topping up the battery daily.

In my week of testing, which included a mix of highway stints and urban errands, the trip computer reported an average of 7.2L/100km.

That’s well above the official figure, but still pretty reasonable considering the type of driving I was doing.

Charging is simple enough. The Sorento uses a Type 2 charging port, and on a standard 3.3kW AC charger, the 14kWh battery can be charged from 15 to 95 per cent in about three hours and 26 minutes.

Kia includes a portable AC charger with this grade, which is a handy bonus for charging at home or on the go.

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 Sorento PHEV hits most of the right notes when it comes to power delivery and gear shifts. Occasionally, there's a slight hesitation between whether the engine or electric motor should take the lead - like a dance partner who’s just a touch out of step. It’s noticeable, but not disruptive.

Most of the time, the transition between power sources is smooth, and there’s more than enough grunt for overtaking or merging confidently.

The suspension has a springy, soft edge to it and you’ll feel some movement over bumps but it’s never harsh or uncomfortable. It corners surprisingly well for a large SUV, with responsive, albeit lighter, steering. Body roll is present if you push into tight bends, but that's par for the course in a seven-seater.

Regenerative braking is subtle, almost too subtle. There’s not much feedback, and it can feel a bit heavy underfoot in stop-start traffic. It’s not a deal-breaker, but worth noting if you’re expecting the more pronounced regen feel you get in some other hybrids or EVs.

The cabin remains quiet at both urban and highway speeds, making it easy to hold a conversation across all three rows. Visibility is generally good, though the thicker pillars take a little getting used to. The digital rearview mirror is a great touch when the back seats are loaded with people or gear.

Parking is refreshingly simple thanks to a crisp 360-degree camera and front and rear sensors. One of my favourite features is the remote smart parking, which lets you move the car forwards or backwards via the keyfob, a lifesaver in tight parking spots. Just don’t teach your eight-year-old how to use it ...

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 Sorento is backed by Kia’s seven-year/unlimited-kilometre warranty, which keeps the Sorento competitive in a market that is slowly starting to offer seven/year plus terms as standard.

You’ll also benefit from capped-price servicing for up to seven years or 70,000km, with an average cost of $764 per visit. That’s on the pricier side, especially when compared to some rivals.

Service intervals are every 12 months or 10,000km, whichever comes first, so if you’re someone who racks up the kilometres quickly, that could mean more frequent trips to the service centre than you’d like.

It’s also worth noting that the GT-Line PHEV requires a minimum of 95 RON premium unleaded petrol, which is something to factor into your ongoing running costs, particularly if you're already trying to offset fuel usage with regular charging.

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.
