BYD Sealion 6 vs Deepal S07

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.

The Deepal S07 has the makings of a great family friendly EV, but with some quirks that really need to be ironed out.

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.

If you’re left a little underwhelmed from the bland same-sameness of so many new SUVs, I reckon you’d like the Deepal S07 in the metal. Because boring it ain’t.

It’s sharp and purposeful and full of lovely creases and angles, and it stands out on the road — especially in this 'Sunset Orange' colour.

Deepal says it was designed in Turin, Italy, but I'm not sure that matters much. I mean, being in Italy doesn’t guarantee design success – just look to the modern Lancia range for proof – but I guess it’s something for a newish Chinese brand to hang its hat on.

Inside, the design is lovely, too. I like the materials used, the extended dash and the size of the central screen (though it tilting towards you or the passenger is probably overkill). And the flat-bottom wheel is a nice touch.

I'd like to know where the air con was designed, though. It feels massively underwhelming on a piping hot Sydney day. The main outlet is at the bottom of the dash, which is perfectly positioned to chill absolutely nothing, and you can’t really change the direction of the vents, either. Or, at least, I couldn't figure out how to.

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.

At just over 4.7m long and 1.9m wide, with a 2.9m wheelbase, the Deepal is a sizeable proposition, which means good passenger room and decent luggage space.

Starting at the boot, you’ll find 445 litres with the rear seats in place, but with the seats folded flat that number grows to 1385 litres. There’s a frunk up front, too, that holds another 125 litres.

In the back, the room is ample for full-size adults. When sitting behind my own 175cm driving position, I had more than enough knee and headroom to sit comfortably. 

There’s also a heavy pulldown divider that’s home to twin cupholders, and there are two more up front, and USB connection points galore. Bonus points for the back seat riders being able to adjust their own air temps, too.

It’s easy picking in the Deepal range, given there’s one model with just the one trim level, simply called the S07.

It’s currently $58,521 drive-away in NSW, or $53,900 before on-road costs. And that’s probably about right. You can get an entry-level Kia EV5 for $56,770, though with less range and kit, or the XPeng G6 Standard Range for $54,800, though that’s before on-road costs. The new Model Y is a bit of a jump, at $63,400 on the road.

For that you get 19-inch alloys, a fixed sunroof with a sun shade, LED lighting all around and a powered boot. 

Inside, there’s a giant 15.6-inch touchscreen that can swivel towards the driver or the passenger, wireless Apple CarPlay and Android Auto, a 14-speaker Sony stereo and wireless device charging.

There’s dual-zone air con, the seats (heated and ventilated up front) are trimmed in synthetic leather and there’s an interior camera with gesture control, so you can use a kind of sign language to take a photo, control the stereo or answer or hang up the phone. It's weird and makes you look like a turkey, which is why I used it once and once only, but you might like it.

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 S07 is powered by a single 160kW/320Nm rear-mounted electric motor and it's rear-wheel drive. That’s enough output, says Deepal, to push the S07 to 100km/h in 7.9 seconds — not bad for a two-tonne-plus SUV.

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 79.97kWh ternary lithium battery delivers a claimed driving range of 475km. It is, however, set up for just 92kW DC fast charging, which means going from 30 to 80 per cent will take just over half an hour. That’s at an appropriate DC fast charger, of course. Your 7.0kW AC home wallbox will take 11 hours, or eight hours if you can draw 11kW.

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. 

Binging, bonging safety systems aside, the Deepal S07's drive experience is relatively peaceful.

It can feel heavy, and isn't dynamically perfect through tighter bends, and even in the city the suspension - which does a good job ironing out most road imperfections - can clang over sharper, bigger stuff, especially if you're too enthusiastic with a speed bump.

But provided you're not asking too much of it on some twisting pass, and you're gentle enough over really big bumps, the S07 behaves much as you'd expect a big, wafty electric SUV might.

That is, with a smooth flow of power, steering that isn't overly direct, but not overly sharp either and with comfort the order of the day.

There are some annoying quirks, though, that would seem easy enough to iron out. The safety systems are often intrusive – and other Chinese brands can get them to be far less annoying – but I also found the tech and user interface annoying and fiddly, which again would be easy enough to fix.

Handing out a low score for a five-star ANCAP car seems harsh, but bear with me.

All the major bases are covered, the standard spec including auto emergency braking (AEB) with car-to-car and 'vulnerable road user' (pedestrian, backover, cyclist, motorcycle) detection, blind-spot monitoring, lane-departure warning, lane keeping assist and more. And there are front, front side (chest), side curtain and front centre airbags.

But the single biggest drawback of the Deepal experience has to be the most annoying, infuriating active (crash-avoidance) safety systems I’ve ever come across. Honestly, it has to be experienced to be believed.

For one, whenever I wear sunglasses it gives me an “occlusion” warning, which I genuinely had to Google, but that’s nothing compared to the driver attention monitor, which seems rigged to go off if you so much as blink, sending chimes binging and bonging throughout the cabin, increasing in number like a bomb about to go off.

And if you have to turn them off every time you get in, you have to wonder if they have any business being there at all.

So yes, it wears a maximum five-star ANCAP rating from assessment in January this year, but it’s a tree falling in the forest, kind of vibe, like if a car has every active safety system known to man, and you want to switch them off every time you get in, is it any safer than a car that doesn’t have any systems at all?

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 S07 is covered for seven years or 160,000km, while the battery is covered for eight years or 240,000km.

Servicing is required every 12 months or 10,000km, and the brand’s capped-price servicing program covers the first seven services (or eight, if you include the initial 5000km check-in, which is free), for a total $2981.43 (or an average of $426 per paid workshop visit).
