BYD Sealion 6 vs Zeekr 7X

What's the difference?

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.

Not the most comprehensive of tests, I'm afraid. But early signs are good for the Zeekr 7X, which ticks plenty of on-paper boxes, looks sleek and fresh and feels sorted from behind the wheel.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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.

It’s a sleek-looking SUV, the 7X, and is nowhere near as boundary-pushing as its stablemate sibling, the Polestar 4, which rides on the same platform. For one, the Zeekr has a rear windscreen.

Zeekr calls it 'hidden energy' design language, which I take to mean, at least partly, that you can’t immediately tell what’s powering it. It could pass as an internal-combustion car, a hybrid, PHEV or EV; at least until you look closely.

There are light bars front and back, but sadly we miss out on what the brand calls its 'Light Curtain' - a pixel-filled bar of light that spans the entire front end. Apparently it fell victim to the ANCAP crash-test requirements and has been replaced by a black cover.

Even without it, I dig the 7X’s athletic stance. It looks good in the metal, especially finished in deep green paint.

Inside, it’s a pretty plush-feeling cabin, without being revolutionary, and the big central screen and digital dash are bright and clear. The addition of a camera to monitor back seat passengers without having to turn around is a clever touch, too.

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.

The 7X stretches 4787mm in length, 1930mm in width, 1650mm in height and rides on a 2900mm wheelbase.

As is pretty typical of electric SUVs, interior space is great, especially for backseat riders. I'm 175cm and have heaps of knee and headroom behind the driver's seat set to my position.

Storage space is good, too, with a deep bin between the front seats, a pull-down divider in the back row and pull-out draws beneath the back seat which mean you can hide laptops or valuables when you lock the car.

One key quirk, though, is the location of the USB charge ports in the back, which are accessed through the pulldown seat divider. It means that, should there be three passengers in the back, you won't be charging any devices.

The boot is 539 litres of flat, wide space – though that number grows when you drop the 60/40 split-folding back row. Rear-drive models also get a 62-litre 'frunk'.

There are three ways into the 7X, with two rear-drive models and one AWD Performance completing the trilogy.

That story begins with the 7X Rear-Drive, which gets the smallest battery and lists at $57,900, before on-road costs. Next is the Long-Range at $63,900, which is also a rear-drive model but nabs a bigger battery and a longer driving range.

Finally, the Performance is $72,900, and is the only twin-motor model. It scores the same 100kWh battery as the Long Range, but significantly ups the performance, which in turn dramatically lowers the zero to 100km/h time.

Standard kit is pretty impressive across the board, with the entry-level model scoring 19-inch alloys, LED lighting all around, a powered tailgate, a glass roof (with powered shade) and ambient interior lighting.

Tech is handled buy a 16-inch central touchscreen with Apple CarPlay and Android Auto and there are two 50W wireless charge pads. You also get a digital dash, tri-zone climate and a 10-speaker stereo.

The Long Range model adds a better 21-speaker stereo and a head-up display, while the flagship Performance gets trick auto-opening and closing doors (you just push a button in the pillar to open and step on the brake to close), as well as genuine Nappa leather trim, 21-inch alloys and very good adaptive air suspension.

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.

The two rear-drive ZX models share the same rear motor producing 310kW and 440Nm. Not stratospheric numbers but the powertrain delivers plenty of useable, real-world grunt, with both variants reporting a zero to 100km/h time of 6.0 seconds.

The AWD Performance model really ups the grunt, though, adding a second electric motor at the front axle lifting total outputs to 475kW and 710Nm and dropping the 0-100km/h run to a crazy-brisk 3.8 seconds. It’s also the only model to ride on the very good adaptive air suspension as standard.

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 cheapest 7X variant scores a 75kWh LFP battery, while the Long Range and Performance nab a 100kWh NCM unit. All have an 800V electronic architecture, allowing for mega charging speeds of up to 450kW DC charging (actually 420kW on the 100kW battery).

Now, I don’t think we have chargers capable of pushing that much juice in Australia, but even using our 350kW chargers Zeekr promises you’ll go from 10 to 80 percent charged in 16 minutes or less. AC charging is up to 22kW, too.

In terms of driving range, you can expect 480km in the rear-drive, 615km in the Long Range and 543km in the Performance, all on the WLTP cycle.

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. 

The 7X is very much the vehicle Zeekr has been waiting for in Australia, so expectation weighs heavy on its metallic shoulders. Happily, and not to spoil the ending, it largely lives up to those expectations with our taste test revealing an electric SUV that shines in most areas.

Our drive experience took place at one of Australia’s longest and fastest race circuits, The Bend outside Adelaide. And not in the AWD Performance version, but in the less-powerful Long Range model. Not exactly the natural environment of a circa 2.5-tonne electric SUV, then.

And while the rear-drive Zeekr is no out-and-out performance car, the 310kW and 440Nm served up from that rear-axle motor is plenty to get the 7X up and moving, with the power arriving in a steady and unbroken stream that saw us pretty easily push to 200km/h on one of the track’s lengthier straights.

I’d argue that’s more than enough grunt to satisfy most, if not all, Zeekr owners without them having to dig deep for the Performance model. But there’s no escaping the fact this is a heavy vehicle, and one inspired by efficiency, not the red mist of racing.

So, things start to drop away a bit when the lesser 7X is really pushed, with an off-putting kind of buffeting movement at speed and sometimes spongey-feeling dynamics a reminder that this is a vehicle more at home on public roads.

The AWD Performance, however, sharpens things up considerably, helped by its adaptive air suspension and all-paw grip. It feels far tighter, grippier and more composed through corners. Sadly, by the time I jumped in, my lead-footed colleagues had drained the battery to the point where I could only accelerate at 50 per cent capacity, which made the AWD slower on the straights than then RWD model, but it made up plenty of lost ground in the way it corners.

All of this is, of course, is likely to be of little relevance to any 7X customers, who are more likely to find themselves on the moon than they are the main straight of a race track, and so my opinion hasn’t changed — the AWD is faster and more technically advanced, but when you boil it down to the actual life a mid-size electric SUV will live, I think the smart money is on the Long Range AWD model.

Side note: We also did some pretty serious off-roading (again, something no owner is likely to do) in the AWD model, and I can report that the softest suspension, steering and accelerator settings add a cosseting comfort to the drive experience on rough roads, and that there is some genuine of-road capability on board.

How it drives on actual roads? For that, you’ll have to wait just a little longer. But early signs are good for Zeekr’s most important model.

The 7X wears a maximum five-star Euro NCAP assessment and I want to point out a pretty wild feature. Standard across all trims is a high-def camera in the B-pillar aimed at the rear seats. You can cover it, if you’d like, but the idea is that anyone up front can hit a button near the central screen that will pull up a high-def feed of what’s happening in the back seat. So, no more having to turn around to see what the kids are up to in the back seat.

Happily, all 7X models get the same safety suite, which includes a 360-degree camera, autonomous parking and 15 ADAS functions.

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.

The Zeekr 7X is covered by a five-year, unlimited-kilometre warranty, while the battery is covered for eight years or 160,000km. There’s five years' roadside assistance thrown in, too.

Servicing is recommended every two years or 40,000km, with what the brand describes as optional health checks in years one, three and five (the first one's on the house).

Go for all the services, including the optional ones, and you’re looking at $2415 over the first five years. Skip the optional ones, and it’s more like $1755.
