BYD Sealion 5 vs Deepal S07

What's the difference?

While the BYD Sealion 5 lacks the polish of some more established plug-in hybrids, it has a seriously compelling price advantage over some competitors. It makes a base-model Mitsubishi Eclipse Cross PHEV feel positively outdated and it’s $13,800 cheaper.

BYD's lack of ANCAP rating for the Sealion 5 and the uncertainty around it still being a new brand are downsides, even if BYD is quickly moving past the latter. But being the most affordable PHEV available while having this much showroom appeal is bound to work in the Sealion 5’s favour, just don’t expect a dynamic masterpiece once you’re out on the road.

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

The BYD Sealion 5, from the outside, is inoffensive but also uninspiring. That’s likely not such a bad thing for a mid-size SUV – it’s rare you’re hearing someone talk about how beautiful the Mazda CX-5 or Toyota RAV4 is. 

Its quartet of colour palette options comes in on the safe side, too. Aurora White is standard, Atlantis Grey, Harbour Grey and Cosmos Black are cost-options.

Our test car is Atlantis Grey, which is interestingly quite blue. 

The relatively upright shape is a slight departure from the more ‘aquatic’ silhouettes of BYD’s line-up, but the front grille and light layout are decidedly in step with the brand’s oceanic design language. There’s a bit going on, you could say.

The slimline tail-lights are the rear, especially from a three-quarter angle to the side, look attractive and help break up the rear without looking messy.

The Sealion 5’s design is overall net-good, but it’s inside where the mid-sizer feels like you’re getting plenty for your dollar.

The seats, despite the leather fakery, feel like decent material, and the layout uses buttons and physical controls cleverly without feeling outdated.

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.

To actually interact with the interior is, at times, another story. BYD’s tech interface is generally easy to manage, but could be simpler when it comes to navigating menus for the sake of driver distraction.

While larger text and buttons would be welcome, the multimedia system is easy to use when parked, and the functionality is impressive for the price point.

Winning more points for the Sealion 5, though, are the physical controls – buttons and the traditional gear selector – which make the cockpit much more intuitive while on the move.

Ergonomically, though, the adjustment between the steering wheel and driver’s seat could do with some work, as I found it difficult to find a truly comfortable driving position. This is coming from someone 178cm tall, a very normal height in Australia.

Better adjustability on the steering column would be helpful, as it’s something I’m not sure I’d ever get totally used to.

Visibility and physical space inside the Sealion 5 is impressive, though. The car is 4738mm long, 1869mm wide and 1710mm tall, and the roof and window lines don’t swoop too aggressively towards the rear.

There are low window shoulders even into the rear, so light isn’t at a premium, though under-leg support could be better on the pew.

It’s otherwise un-cramped. The 2712mm wheelbase means decent legroom for second-row folk, plus behind the 60/40 split-fold seats there’s 463 litres of space for luggage. That becomes 1410L with the seats folded.

There’s unfortunately no spare tyre, just a tyre repair kit.

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.

The Sealion 5’s front wheels are driven by a combined maximum of 156kW thanks to a 1.5-litre four-cylinder petrol engine (145kW/300Nm) and a permanent magnet synchronous motor (72kW/122Nm).

BYD claims a 0-100km/h sprint of 7.7 seconds for the Sealion 5 Essential, four tenths faster than the Premium despite only a 61kg difference in kerb weight.

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.

With a charged 12.9kWh lithium iron phosphate (LFP) battery and a full 52-litre (95 RON minimum) fuel tank, BYD reckons the Sealion 5 Essential can cover 1001km under NEDC testing, which is optimistic. It claims 71km can be done on EV power alone.

Not only due to the lenient nature of NEDC testing (WLTP is more common and usually results in lower ranges), but the reality is that once the battery is flat, the engine is doing a lot more work.

Charging is slow, limited to 3.3kW (AC only), which should take between 4 and 5 hours to charge from the lower end of the gauge for the battery size. Given most PHEV owners will do this overnight at home, that’s certainly not the end of the world.

Claimed consumption figures are 1.2L/100km with more than 25 per cent battery charge, or 4.5L/100km when it dips below that.

Realistically you could do sub-50km trips and use no fuel, or never plug your Sealion 5 in and see fuel consumption soar. In any case, anything close to 1001km in a single run is extremely unlikely.

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.

You might expect a car at this price, regardless of its drivetrain, to be underwhelming from behind the wheel.

That, then, makes it even more pleasantly surprising that the BYD Sealion 5 is actually rather competent. Not massively exciting or dynamic, but certainly not a disappointment.

The Sealion 5 is, save for a couple of arguably minor annoyances, quite easy to get used to and drive.

Firstly, when making proper use of its electric power, the drivetrain provides enough shove for its intended use. It’s not overly powerful, but you won’t have trouble overtaking. It’s the same with most of the inputs, the steering is light but not completely numb – again about right for how the Sealion 5 will be driven.

Perhaps its biggest departure from expectations based on other cars from China is its suspension is on the stiffer side of things, but again it’s not unruly or too rugged. In fact, it does provide a better sense of control than many of its compatriots.

Again, the biggest issue with the Sealion 5 day-to-day is its driving position, the steering column adjustment isn’t up to scratch and there’s not really a perfectly comfortable seating position (I’m a very standard 178cm).

On long trips, you might also find the engine gets quite noisy once the battery power is gone as it works hard to pull the mid-size SUV along under acceleration.

Its driver-assist systems are, you might be pleased to hear, on the calmer side of things – BYD is getting better at calibrating its safety features and I didn’t find myself rushing to switch it all off as quickly as usual.

It can still be a bit too persistent in its lane-keeping, but it’s a big improvement on the way things were.

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 has a six-year/150,000km warranty, which is probably more than you’d need in terms of distance but is behind many competitor brands’ timelines – seven to 10 years is becoming the norm, even if it’s conditional.

An eight-year/160,000km warranty covers the battery, which is about par for the industry.

Servicing for the first five proper services ranges from between $285 and $930, plus there's a free check-up six months into ownership and a total cost over the span of $2355 – an average of $471 per service.

BYD has just over 100 dealerships in Australia, so finding one for servicing shouldn’t be too challenging.

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).
