Mercedes-Benz Eqe53 vs BYD Sealion 6

What's the difference?

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.

So, should Toyota, Tesla, Hyundai and others be worried about the arrival of the Sealion 6 and BYD’s new DMi powertrains? Yes, but not because it represents any major breakthrough in technology or dynamic prowess. 

Instead, the strength of the Sealion 6 is how average it is. It may not be the obvious class-leader in any particular area, but it does a good job in almost every measurable aspect and doesn’t possess any major flaws.

Yes, there are still questions about the long-term dependability of BYDs but that’s a risk any new owner will need to accept. But the very sharp pricing should tempt plenty of buyers to take that chance and continue BYD’s steady upwards trajectory in the Australian market.

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.

This is one area where BYD has a mixed record. Not to be unkind or create an international incident, but the Chinese car industry has a history of not being totally original with all of its automotive designs.

However, things are improving and the Sealion 6 is a good example of the Chinese industry learning to develop its own style. While there are some subtle hints from European models, overall it’s a smart-looking mid-size SUV with some character to it - rather than being a bland imitation of something else.

One area where the Sealion is a cut above its competition is its size, being longer than and wider than the RAV4, Mitsubishi Outlander and Nissan X-Trail.

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.

That external size translates to a roomy cabin, which also has some flair to the design but thankfully a bit more restrained than the smaller Atto 3 - which is a bit over-the-top in this reviewer’s opinion. 

The element that sticks out immediately is the large central touchscreen which, like other models in the range, can rotate either vertical or horizontal, depending on your preference.

I don’t understand the point of this, because when rotated vertically it impacts your forward vision and can interfere with the air conditioning vents; and I can’t even see it with my polarised sunglasses.

It simply makes more sense horizontally, but I guess all carmakers are looking for catchy gimmicks these days. But while it may seem like a cool party trick it remains somewhat confusing to me, like one more thing to go wrong. But maybe I’m just getting old and grumpy.

What I do like and think is a great idea is double smartphone charging pads in the centre console. And overall the design of the cabin feels well thought out and has plenty of useful storage areas.

The seats are fine, a little flat and the fixed headrests are irritating, but overall they’re soft and supportive enough.

The key in the second row seating is the amount of space, with the extra length of the Sealion 6 compared to its rivals showing up with more knee room in the back for families with growing teenagers or those who need to carry their adult friends.

There’s also a pair of USB ports in the back too, so everyone can keep their electronics charged.

The boot is a good size, measuring 425 litres on paper, and has a nice long and wide floor. But some of that space is thanks to the lack of a spare - so that counts against it in my book.

Price is key to BYD’s success in Australia. Quite simply, the Chinese brand has undercut its rivals and consumers have responded to that, unsurprisingly in these tough economic times. The Sealion 6 follows the same path blazed by the Atto 3, Dolphin and Seal, offering plenty of vehicle for your money.

BYD Australia has kept it really simple, offering just two models - Dynamic and Premium - with very similar specification and separated primarily by powertrains.

The Dynamic is a less powerful, two-wheel drive option, while the Premium gets more grunt and all-wheel drive; but we’ll detail that later.

Both the Dynamic and Premium come with 19-inch alloy wheels, power-operated tailgate, a panoramic sunroof, powered front seats that are heated and cooled, a 15.6-inch touchscreen, Infinity premium audio, two wireless phone chargers and wireless Apple CarPlay and Android Auto.

The only non-powertrain difference between Dynamic and Premium is a head-up display on the latter model.

One noticeable absence from the Sealion though is a spare tyre. There’s not even a space-saver, just a tyre repair kit, which is disappointing and out of touch with the unique demands of the Australian market.

The Dynamic is priced from $48,990 (all prices exclude on-road costs), while the Premium starts at $51,990.

To put that into context with its competition, the Toyota RAV4 Hybrid range begins at $42,250 for the GX and stretches to $51,410 for the range-topping $51,410.

While, if you’re looking at an electric alternative, the Tesla Model Y currently starts at $55,900. The most direct rival, however, is the Mitsubishi Outlander PHEV which is only available with all-wheel drive and stretches from $57,290 to $73,790 across five variants.

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.

While BYD has made its name in Australia as an all-electric brand it has always referred to itself as a 'new energy' company, and the Sealion 6 (and upcoming Shark ute) are why.

That’s because these feature BYD’s new 'Dual-Mode Intelligence' (DMi) powetrain - a hybrid system to you and me.

As mentioned above, the biggest difference between the Dynamic and Premium models is the powertrain, with two reasonably different systems.

The Dynamic is powered by a 78kW/135Nm 1.5-litre four-cylinder petrol engine, paired with a 145kW/300Nm electric motor - making for a combined system output of 160kW/300Nm. Notably, this powertrain only drives the front wheels.

In contrast, the Premium has an all-wheel drive set-up, combining a turbocharged version of the petrol engine (good for 96kW/220Nm) with a pair of electric motors, one on the front axle and one on the rear to produce a combined output of 238kW and 550Nm.

Both models get the same 18.3kWh ‘Blade’ battery, which is BYD’s proprietary technology underpinning all of its models and is attracting attention from other brands.

For reference, the Outlander PHEV has a 20kWh battery, Nissan’s X-Trail e-Power has a 2.1kWh battery, while the more conventional RAV4 Hybrid has just a 6.5Ah battery.

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.

There are multiple modes to drive it in, including electric only, with the Dynamic able to go up to 92km on a single charge, while the Premium manages a claimed 81km.

However, it's important to note these are the NEDC standards and not the more real-world like WLTP,  so you may not achieve those in practice.

The claimed fuel consumption is an impressive 1.1L/100km for the Dynamic and 1.4L/100km for the Premium although again achieving those in the real world will take some effort.

With a 60-litre fuel tank BYD claims the Dynamic has a driving range of just over 1000km, while the Premium can manage around 960km.

It's also worth noting the Sealion 6 comes equipped with vehicle-to-load charging which means you can draw power from the batteries to run small electronic devices if you need to.

It’s a bonus feature that may or may not be of use, but is one of those things that may come in handy one day to get you through a camping trip or a BBQ at the park.

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 drove the Sealion 6 Dynamic and despite having the less powerful powertrain it feels good on the road. The DMi system offers good performance, with quiet acceleration off the mark and a good integration between the petrol engine and electric motors. We haven’t driven the Premium yet, so we can’t make any comment on how different it feels.

It’s hard to make a definitive call on the Sealion PHEV powertrain because, like every plug-in hybrid, its greatest strength relies on how the owner operates it.

If you don’t charge the battery every day or so, you’ll just end up lugging around a battery and electric motor for little benefit. However, if you do keep the battery topped up, you can do most of your urban commuting without needing to turn the petrol engine on, which should result in some very low fuel consumption figures.

The company clearly knows this, which is why BYD Australia is offering a complimentary home charger to the first 3000 customers who order a Sealion 6.

Not only will that encourage sales but it will also help owners become evangelists for PHEVs in the future, because they’ll have the best possible experience.

So, a large part of its strength or weakness rests on the owner’s behaviour and that’s something we can’t assess.

As for the rest of the driving experience, the ride comfort is fine. It can’t match the class-leaders for compliance or dynamics, but the Sealion feels pleasant to drive around the urban environment and on the freeway at speed.

Biggest criticism is the steering is very, very light. While that makes parking easier, it feels so light you get very little feedback from the front wheels so it can feel vague at times.

Overall the driving experience is best described as fine. It doesn’t have any major vices but neither does it set any new benchmarks. 

Both Sealion 6 variants come equipped with autonomous emergency braking, front and rear cross-traffic alert/braking, 'Forward Collision Warning', 'Rear Collision Warning', lane departure warning/prevention, blind-spot detection, traffic-sign recognition, door-opening warning, trailer stability control, auto high beam, a 360-degree monitor, adaptive cruise control as well as front and rear parking sensors. Plus, it can even detect if you’ve left a child or pet inside the car.

ANCAP had not crash-tested the Sealion 6 at the time of publication, but with its comprehensive list of safety items it should tick most of the boxes when it comes to protecting its occupants and pedestrians.

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.

BYD is a small company but has partnered with mycar service centres to make maintaining your Sealion 6 easier. The Sealion is covered by BYD's six-year/150,000km warranty as well as its 10-year capped price servicing plan.

Service intervals are every 12 months/20,000km and prices range from $265 up to $1184 for the major eight year/160,000km tune up. Over the first five years, in keeping with most of its rivals, you’ll be paying $1648.

As I’ve written in previous BYD reviews, the biggest question mark hanging over the brand is arguably its long-term prospects. Quite simply, the brand is still too new to know how well it will perform on the used car market.

We also can’t tell you how it will hold up from a reliability point-of-view. We’re not suggesting there’s any doubt over its quality, but each car brand must prove itself reliable and dependable over time, and BYD hasn’t had that time yet.
