Kia Sorento vs Mercedes-Benz Eqe53

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.

In the wild new world of fully electric cars there isn’t really an ‘average’ of what to expect. If there was, I’m sure the EQE 53 would exceed it. Its electrification brings the ambiance of a luxury car, while its performance reminds you of what AMG is capable of.

There’s a bit of the mechanical engagement of AMG missing, a relatively small boot, and some won’t be sold on the function-over-form looks, but the EQE 53 is a pleasantly surprising look at the future of fast Mercedes.

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 EQE is certainly a departure from the classic lines of the current E-Class sedan. Mercedes-Benz has chosen to take a completely new approach for the electric era, embracing the need for ultra-low drag designs, and a corresponding newfound love for curvaceous surfaces.

It’s fairly imposing too with enormous wheels and an abundance of panels. Needless to say some will find this new design direction challenging. It proved quite controversial in the CarsGuide office, at any rate.

I can say it looks a bit more approachable when witnessed in the metal, and the AMG branded 53s I sampled for this review added a few more much-needed points of interest to this single curve of a design.

This is particularly notable around the rear of the EQE 53 which adds a little tail spoiler and glossy rear diffuser, which help accentuate the width and terraced design of the rear window.

Around the front is a little more featureless, with the blanked-out grille losing the intricate three-dimensional appeal of this car’s combustion equivalents. There’s just something a bit plain about the EQE’s face, although Mercedes has tried to spice it up with interesting headlight clusters.

The inside is spectacular, with a smorgasbord of screens and lights to match an abundance of glossy touch-based surfaces. Some may not be sold on the over-the-top approach, but it feels as futuristic as an EV should be.

The material choices are nice, too, with soft-touch materials atop the dash, doors, and running down the centre console. The ambient lighting is particularly flashy, and works in with the consistent single-piece sort of design which makes up the whole dash.

While the LEDs might be a little too much for some, there are some more subtle detailing points, like the way the centre air vents are delicately worked into the flow of the dash, and the rotor designs of each vent at the edges are intricate pieces.

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.

The EQE is plenty practical up front, with an odd SUV-like seating position providing a commanding view of the road. This seat positioning isn’t an accident or a necessity of facilitating batteries under the floor, but a deliberate design decision by the brand to try to emulate some design choices which have made SUVs so popular.

The result is surprisingly effective, but doesn’t help the view out of the rear of the car, which is a restricted letterbox aspect courtesy of a slinky roofline and tall boot lid.

Still, peering down on the road lets you position and park this large EV more easily. Adjustability isn’t bad for the front passenger, and space is healthy both in terms of width and height. One dimension which can’t be altered is the particularly tall dash height, and while this is largely overcome by the taller-than-average seat, it could be an issue for shorter drivers.

Storage is great, with a big bottle holder and bin in the doors, a huge cutaway below the floating centre console for storage, with an elastic strap for tying down objects. There are a further two bottle holders in the centre console and a bay with a wireless charger, too, and the split-opening armrest box is deep.

One of the more divisive points of this car’s practicality offering is the screen-based functions. Everything has been moved into the massive centre screen. There are no tactile buttons or dials for this car’s functions, with it all controlled through context menus.

To be fair, with the amount of real estate on offer, the touch elements can afford to be massive, and there is a permanent set of climate controls at the base of the screen, but adjusting these functions on the fly is never as easy without physical feedback.

The same goes for the touch-centric wheel controls. Benz says the idea with the four-zoned touch panels on the wheel is to offer unrivalled ability to control the car’s functions even when the wheel is at an angle, but it is also easy to accidentally hit various touch functions, and they can require some delicate action to use properly.

The back seat is impressive. It maintains the tall seating position of the front, letting you look down on the road as though you’re in an SUV, and the comfortable seating and surfaces continue. Legroom is particularly impressive, with leagues of space behind my own driving position. Headroom is even okay considering the descending roofline. It’s quite dark in the EQE 53 we tested thanks to its black-on-black trim, giving the illusion of a space which is smaller than it actually is.

Storage is good, too, with a big bottle holder in the door cards, quad-zone climate control, complete with a separate touch panel for rear passengers, adjustable air vents, and solid clamshell pockets on the backs of the front seats.

The EQE has a boot capacity of 430 litres which doesn’t seem enormous given the footprint of this car, and no doubt has a lot to do with its slinky aerodynamic design around the rear. There’s no ‘frunk’ either so this is a car perhaps more focused on driving and being driven in than its ability to carry things.

We don’t yet know which EQE variants will be offered in Australia. The car we drove for this review, the EQE 53 AMG is the top of the range, and will be the launch variant in Australia, but the brand is yet to settle on how it will fill the line-up underneath.

Representatives said to expect at least two more Mercedes-Benz (as opposed to AMG) branded variants, with the option of a rear-wheel drive entry model and an all-wheel drive mid-grade. Whether they adopt the same spec level as the European-market EQE 350 remains to be seen.

As for the EQE 53, CarsGuide understands a price north of $200,000 is likely when it arrives before the end of 2022.

Its rivals will include other high-end four-door models like the Porsche Taycan, Audi e-tron GT, and the updated Tesla Model S. In the coming years this segment will continue to heat up with the yet-to-launch Hyundai Ioniq 6 and Polestar 5.

The EQE is fairly large, offering dimensions comparable to that of the CLS which came before it, and is quite unconventional in a host of areas.

The standard suite of equipment we sampled is impressive, too, with performance enhancements on the 53 including four-wheel steer, adaptive dampers, a performance brake package, and torque-vectoring all-wheel drive.

Massive 21-inch alloy wheels featured on our car, and there is also the option overseas for even higher performance carbon ceramic brakes.

Outside also features LED headlights, DRLs, and tail-lights, while inside impresses with the massive dash-spanning ‘Hyperscreen’ with panels for the digital dash, centre multimedia screen, and a third panel for the front passenger.

This set-up is optional on the EQE range in Europe, but we’ll have to wait and see what becomes standard for the Australian market. The car we sampled had wireless phone mirroring tech, wireless charging pads, built-in navigation with augmented reality directions, a head-up display with configurable panels, and full USB-C connectivity throughout.

Quad-zone climate also features, as does the brand’s latest steering wheel, in our case clad in Alcantara and leather trim.

The seats, even on the EQE 53 ship standard with the ‘Artico’ synthetic leather trim, although they can also optionally be upgraded to full Nappa leather. Electrical adjustment is standard for the front seats.

It’s a flashy cabin which feels primo, and little touches like unique materials for the EQ range across the dash and ambient lighting configurable to any colour you can dream up are neat, too.

Check in closer to the EQE’s local arrival time before the end of 2022 for more accurate pricing and spec, as well as the list of option packs.

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 EQE 53 punches out huge power, with the standard car producing 460kW/950Nm from its dual electric motor set-up, or with the 'AMG Dynamic Plus Pack', producing even higher figures of 505kW/1000Nm.

Clearly, AMG’s electric vehicles will safely outrun their dramatic combustion predecessors. In fact, with the Plus Pack, the EQE 53 is capable of moving its bulk from 0-100km/h in just 3.2 seconds. Extreme for something carrying a whopping 90.6kWh of batteries under the floor.

Enhancements include torque-vectoring all-wheel drive, all-wheel steer, adaptive dampers, and the choice of standard performance brakes or a carbon ceramic package.

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.

Electric vehicles appear to have the same issues as their combustion counterparts, in that they still drop in efficiency the more powerful you make them. In the case of the EQE 53, this means an average WLTP-rated consumption number between 20.3kWh/100km and 23.2kWh/100km.

'Thirsty' for an EV, although it is on par with the Porsche Taycan and still below Audi’s e-tron S.

When it comes to charging the EQE 53 can charge at a rate of 11kW on the AC standard, or a whopping 170kW on DC - allowing 180km of range to be added every 15 minutes. It also has the convenient option of a 22kW AC charger, a welcome inclusion if you intend to charge your car often at public outlets.

Total range for the 90.6kWh battery is 513km on the WLTP cycle.

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 ...

The way the EQE 53 drives was deeply unexpected. Just looking at this massive sedan, I would have expected it to feel burdened by its batteries, and with its length and shape, cumbersome in the corners. That wasn’t the case at all.

The EQE 53 feels remarkably coherent from behind the wheel. The seating position works well to give a nice view of the road, the steering feels a tad artificial but still direct with some AMG magic having worked its way in.

What surprised me most is how agile it feels. Once you gather some speed and attack some corners, this car shrinks. Control is excellent thanks to the massive tyres, all-wheel drive system, and all-wheel steering. It sounds like a lot of complexity, but you don’t notice any of it. Each system does its part to allow you to simply point the car where you want it to go at pretty much any speed. It is very impressive.

The ride feels supple, too, thanks to adaptive dampers, but offers plenty of control. The speed is Tesla-style violent. Put your foot to the floor in Sport or Sport+ mode and you’re thrown to the back of your seat as the car enters a state of warp. AMG says there won’t be a 63 version of this car, and I can’t imagine why you could possibly need anything faster or more capable than this 53 version. 1000Nm of torque!

This overwhelming number perhaps makes it more impressive that it’s hard to extract a squeak from the tyres. Sure there’s torque-vectoring magic at play, but even at full acceleration they hold on for dear life.

It also makes a noise. AMG is very specific about what went into making the soundscape for the EQE because in the electric era its performance can be achieved silently, and the brand knows full well its badge usually comes hand-in-hand with aural drama.

I stuck it in the stock mode and varied my driving from 'Comfort' to 'Sport+.' The sound builds as the car gains speed, but it also interacts with your accelerator and brake inputs, as well as being one of few EVs with a specific noise for regenerative braking. It sounds… odd.

There’s certainly a kind of drama to it, and to me, it’s better to have it as a way of gaining some feedback from the car. But, its artificial nature and loudness became a little too much for sustained driving in Sport + mode. I found the best balance in the more regular ‘Sport’ mode, or even toned down to ‘Balanced’ which puts it in the background.

This leaves quite a void, though. While the sound is welcome, and the throttle alarming, there’s just something missing from the usually brash AMG badge promise.

As an EV, the EQE 53 has three regen modes quite distinct from one another. Mercedes says the choice to have just three modes is deliberate, as it didn’t want to dilute the personality of the car with an overwhelming choice of regen. The three modes include: basically no regen, moderate regen, and the full regen, essentially a single-pedal driving mode. I preferred the strongest setting for efficiency's sake (plus it brakes for you as you let off!).

The EQE 53 is surprising in so many areas, and much more engaging to drive than its exterior visage might suggest. I’m impressed.

We don’t yet know what standard safety equipment will arrive on Australian-delivered EQE variants, but you can expect a high-end suite of gear including auto emergency braking to freeway speeds, lane and blind spot assistance, driver and road monitoring tech, as well as the brand’s rather good autonomous cruise suite.

The EQE pairs the expected set of airbags with an additional driver’s knee airbag and centre airbag for some markets, as well as a second set of side impact airbags for rear passengers. There are dual ISOFIX mounts on the rear outboard seats, and expect there to be the usual three top-tether mounts in Australia, too.

Stay tuned closer to the EQE’s arrival toward the end of 2022 for more accurate specification.

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.

Mercedes-Benz in Australia currently offers a range-wide five-year and unlimited kilometre warranty, a standard which is spreading to other premium brands.

We don’t know what the service schedule or running costs will look like for the EQE range yet, but expect it to be most affordable when chosen with a multi-year prepaid service plan at the time of purchase. Check back closer to its launch time to see the full details.
