BYD Sealion 8 vs Smart 1

What's the difference?

There’s quite a bit to like here. There’s plenty of equipment, and lots of choice in price, trim level and mechanical complexity.

The driving dynamics are fine if you’re not looking for anything sporty although the performance offered by the dual-motor variants must be considered excessive, even if it’s pretty exciting the first time.

Perhaps what’s missing from the Sealion 8 experience is anything that stamps the car as something special within its hotly-contested market segment. Which is another way of saying it offers up the same limitations, most notably in the third row accommodation and access.

You only need to drive a one-box people mover and utilise the rearmost seat, to understand that the two-box SUV, while a pretty marketable thing, is compromised once the passenger count exceeds five. Nothing new there, but nothing new in the BYD, either, to change that narrative.

At which point, the front-wheel drive variant emerges as the most pragmatic choice and probably the one that meets all the important family tasks headed its way for the smallest outlay.

It’s easy to get lost in marketing hype, but — based on first impressions — the Smart #1 does what it says on the tin. This is a Chinese-built SUV that feels more premium than most, and one which is priced to tempt you from one of the German big three. The warranty isn’t good enough, though, and the multimedia screen can be infuriating, but it drives very nicely, especially on suburban roads.

BYD has done its best to give the Sealion 8 its own character and vibe. In fact, it’s a pretty smart looking thing - although still very much a two-box wagon concept - and that’s no given when you consider how much some big SUVs can start to look like large blobs of nothing when you look closely.

There’s the usual Darth Vader stuff at the front, but in profile, the diagonal vent across the front door makes a bit of a statement. The 'plaited' motif of the tail-lights might be stretching things a bit, though.

Inside, the modern board-room feel is invoked by the angular lines and high-tech look and feel of the large info-screens. The panoramic sunroof of the Premium grade also helps brighten up an otherwise pretty dark space.

There is an impossibility pretty model in Smart’s new line-up, but the #1 ain’t it. While the #3 — which has also just launched — is a sleek-looking, coupe-style SUV, the #1 is a top-heavy small SUV that doesn’t shine from every angle.

Front-on, or from a front three-quarter angle, the #1 definitely works, with the brand setting out to remove unnecessary fussiness from the design, leaving smooth and rounded bodywork in its place.

There are no body creases or weird angles here, instead it’s a smooth, fluid-like design that flows from the front LED lights bar to the smooth shoulder lines to the matching light treatment at the rear. 

But it’s at the rear where, for mine, the design begins to fall over. From that angle, the #1 looks skinny and top-heavy, especially when wearing the red hat of the Brabus model.

Still, eye of the beholder and all that.

Inside, though, the #1 kicks all sorts of goals, presenting as a properly premium-feeling EV space that’s swimming with technology and lovely cabin materials.

I particularly love the letterbox-style screen that replaces the traditional dashboard. It’s not distracting or overbearing like some twin-screen set-ups, but clearly shows you the key driving stuff you need when you’re on the road.

Side note, though, the massive central screen is super clear and lightning fast, but as usual you need to spend some (a lot) of time with it to figure out where all the functions are hiding, with most of the car’s key controls hidden within its labyrinth.

And side note two, the background graphics look like they were designed by a cordial-addled child, it is busy, cartoonish and out of keeping with the calm, grown-up nature of the #1’s cabin.

BYD has made sure all three rows of the Sealion 8 are fit for purpose while attempting to make the rearmost row (traditionally the trickiest to get right) less of a downmarket place to be. With that in mind, both rear rows get air vents and climate-control adjustment for that part of the car. There's also a pair of USB-C charge ports in the second row and a single USB-C and USB-A port in the third row. The third row also has cupholders bult into the wheel arch on each side.

With the third row in place, there’s a decent amount of luggage space (270 litres) largely thanks to the Sealion’s five-metre overall length. There’s no spare tyre, but a puncture repair kit lives under the floor (as does the removable cargo blind) and the rearmost luggage space also incorporates a 12-volt socket and luggage hooks.

A pair of pull-tabs drop the headrests and then the entire split third row in a single movement, at which point you suddenly have a five-seater with a huge, 960 litres of luggage space. And if you need to cart gear over people, the second row also folds flat to open up 1960 litres of space.

Up front, the feeling of spaciousness is amplified due to the low scuttle height and what the aviation industry calls the glass cockpit (no analogue dials or gauges at all). The 15.6-inch central info-screen runs the usual apps and control displays but, thankfully, the climate control touch-controls are tethered to the bottom of the screen, so they’re always visible regardless of what else is going on.

The 10.2-inch driver’s display adds a head-up function in Premium trim and displays the usual array of information required to operate the vehicle. But even better is the steering wheel which features a thick, well-padded rim that looks and feels pretty luxe. It also houses the usual buttons for stereo, phone and cruise-control functions.

A really nice touch is the addition of an extra set of tilt controls on the inside of the passenger’s front seat, allowing the driver to control that seat to allow people in or out without leaving their own seat. Nice one.

It is, of course, the centre row of seats that will make or break a car like this for many families. Even though many clans will not use the rearmost seat much of the time, the central row will get a huge workout. So it’s nice to see that leg, foot and headroom are all sufficient for even growing teenagers. Again, the car’s overall length appears to be the key, but it’s also worth noting the centre row seat is comfy and supportive. The outboard positions in the second row also feature heating and ventilation functions.

The third row, however, follows SUV tradition by being strictly for smaller kids. Access past those huge wheel arches is tight, and once you’re in, there’s a combination of dark trim and tiny windows to limit joy.

While it won’t matter to many buyers, the front-drive Sealion 8 is rated to tow 1800kg with a braked trailer, and up to two tonnes in the all-wheel drive version. But there’s no spare tyre fitted, and roadside flats need to be addressed by the included tyre repair kit.

The Smart #1 measures just under 4.3m long, just over 1.8m in width and around 1.6m in height, and it rides on a 2.75m wheelbase. And the perk of the Smart’s EV powertrain, the brand says, is Mercedes-Benz E-Class levels of space in the back seat, despite the #1’s diminutive footprint.

It’s a big claim, and while I didn’t break out the tape measure I can say the backseat feels plenty generous, and because the rear pew slides forwards or backwards by 15cm, you can choose whether you want more legroom or more luggage space.

Speaking of which, pop the auto-opening boot (by hitting the ‘a’ in the ‘Smart’ lettering, which I couldn’t figure out without help) and you’ll find 323 litres of space with the back seat as far back as it goes, growing to 411 litres with it pushed all the way forward. There’s also a 15-litre frunk.

Smart says the #1 weighs 1800kg, adding it will tow 1600kg — but I’m sure you can imagine the impact a heavy load will have on your driving range.

The #1 is available in three trim levels — the Pro+, Premium and Brabus — and pricing (before on-road costs) climbs from $54,900 to $58,900 and $67,900. 

Brabus, by the way, was a lesser-known Mercedes-Benz tuning arm, a little like AMG, which should give you some idea of what to expect from the performance-badged models.

Anyway, that pricing is good enough to undercut key rivals, including the Volvo EX30 (from $59,990) and BMW iX1 ($78,900), and it’s drastically less than Mercedes-Benz's EQA 250 ($84,900), all before on-road costs.

Also firmly in the Smart’s favour is that there isn’t a cheap-feeling model among them, with even the Pro+ feeling properly well-equipped and premium.

Entry-level cars score 19-inch alloys, a panoramic roof, LED lighting, a powered tailgate and a 12.8-inch central screen with wireless Apple CarPlay and Android Auto, and a 9.2-inch digital dashboard. There’s wireless device charging and a decent stereo, too.

The Premium then adds matrix LED headlights, leather trim, a huge head-up display and a better Beats stereo, while the Brabus scores a unique interior and exterior treatment, better suspension and a launch control function.

BYD has managed to keep a lid on the price of the entry-level version of the Sealion 8, by specifying it with front-wheel drive rather than the all-wheel drive of the other two variants. It still gets the same driveline beyond the lack of a driven rear axle, although battery capacity is the other difference.

As such, you’re looking at a 1.5-litre petrol engine (kind of the default powerplant for Chinese SUVs right now) with a turbocharger. With the 19kWh battery chiming in to power the electric motor, the driveline can achieve outputs of 205kW and 315Nm.

In the case of the AWD variants, the larger 35.6kWh battery and extra electric motor ups the potential outputs to 359kW and 675Nm which is a huge jump any way you look at it and gives the Sealion 8 a huge bandwidth when it comes to matching buyer performance aspirations.

All the variants have the potential for a claimed electric-only range of greater than 100km if owners use the plug-in facility to charge either at home or at work. For the AWD variants, the larger battery stretches the EV range to a claimed 152km. On longer journeys or whenever the battery has reached about 25 per cent capacity, the Sealion 8 acts just as any other hybrid with regenerative braking and electric assistance to aid performance.

In suspension terms, the BYD is pretty conventional but if you do pay the extra for the Premium variant, you’ll gain adaptive dampers.

There are two drivetrains on offer here - one shared across the Pro+ and Premium, and another delivering the prodigious power of the #1 Brabus.

The first shared option is a single rear motor that delivers 200kW and 343Nm, which is enough to knock off the sprint to 100km/h in 6.7 seconds. Top speed for all models is listed as 180km/h.

The Brabus, though, adds a motor at the front axle, giving it AWD, which ups the outputs to a punchy 315kW and 543Nm, dropping the sprint to 100km/h to a very fast-feeling 3.9 seconds.

It’s a single-speed EV transmission in each, which means smooth, constant power delivery with no traditional ‘steps’, and all get 'Eco', 'Normal' and 'Sport' drive modes, though the only thing they impact is the accelerator response.

You can add weight to the steering, but that’s a separate item accessed elsewhere in the screen’s sub-menus.

BYD claims a range of more than 1000km for both variants of the Sealion 8, provided you start with a fully charged battery and a full 60-litre fuel tank.

The BYD can also make use of commercial fast-chargers and, when using the maximum 40kW on the FWD version and the 74kW possible for the AWD variant, the charging times from 30 to 80 per cent are both under 20 minutes. The Sealion 8 can also charge at 11kW on an AC socket and the vehicle also offers V2L (Vehicle to Load) capability, meaning it can power on-site work tools, camping gear or even your house at night.

Provided the EV battery is kept at 25 per cent capacity or above, BYD claims a 1.0-litre per 100km fuel consumption figure for the car based on the laboratory test. In the real world, the results will vary enormously depending on where you drive and how the car is used. Deplete the battery and continue to drive at highway speeds, and your actual fuel consumption might easily increase to many times that 1.0-litre claimed figure.

All Smart #1 models share the same 66kWh battery, but how far you can travel between charges comes down to the trim you choose, with the WLTP driving range either 400km, 420km or 440km. The Brabus, of course, covers the least ground between charges, owing to its dual-motor set-up and amped up power outputs. 

When it comes time to plug in, all models are equipped with 150kW DC fast-charging capability, and when plugged into said charger, you can expect to go from zero to 80 per cent charged in less than 30 minutes. 

There’s also 22kW AC charging on board in the Premium and Brabus models, which means you can use three-phase power, but plugged into a regular 7.4kWh home wallbox should see you go from zero to 80 per cent charged in 7.5 hours, which means overnight charging should work a treat.

The first thing you’re going to do in a Sealion 8 is wonder where the gearshift is. It’s a column-shift, but it's not only located where a traditional indicator stalk would be, it looks very much like one, too.

This promises two things. One, you’ll spend a few seconds finding it and two, you’ll try to turn the indicators on with it at least once every drive. (The real indicators are on the other side of the steering column.)

Another note to those test driving a Sealion 8. Sample the front-drive version first. (I’ll get to why in a minute.) When you do, you’ll soon figure out this is a driveline that prioritises electric running. That is, the petrol motor barely ever actually drives the wheels (only at full throttle and higher speeds). Any other time, if the petrol engine is running, it’s to charge the battery that keeps the electric motor purring away. This is how efficiency is defined by BYD.

You’ll also find that the Sealion’s acceleration is purposeful in that electric-motor way, but hardly startling. And when you do smash the throttle and force the petrol engine to drive the axle, you’ll notice that this takes a fair time to play out, and that when everything is grunting as hard as possible, the petrol engine is quite noisy and even a little harsh sounding. Use the driveline sensibly, though, and it’s all smooth and quiet, even if that then means you can hear a little suspension noise creeping into the cabin.

That done, you’re now free to drive the AWD variant. Why wait? Because this thing is seriously off the leash. Bear in mind that 359kW of power is getting on for the thick end of 500 horsepower in the old money, so even though the Sealion 8 is a hefty critter at about 2.5 tonnes, all that power and torque will get it from rest in under five seconds, or thereabouts. The relevance of this to family-car technology is hugely debatable, but it’s one heck of a party trick the first time you try it.

The huge torque also magnifies the Sealion 8’s natural tendency to lift its inside front wheel when accelerating out of a turn. A small tyre squeak can sometimes be heard before the traction control gathers it all together, but even the single-motor variant displays the same trait.

In steering and suspension terms, it’s probably fair to say the Sealion 8 doesn’t unlock any new depths of talent. The ride is pretty comfy but at the expense of body control and the steering points the wheels but doesn’t convey much else to the driver.

That said, the fact everything seems to be tuned to the same frequency means it all works okay. You don’t have too-fast steering fighting the tyres or too firm suspension upsetting the interior calm. Use it as a family would, and it’s 100 per cent fit for purpose.

The #1 and its sister car, the #3, might share powertrains and batteries, but they are designed to drive very differently. The #3 is the sporty one (always code for a firmer ride), while the #1 is supposed to be softer, more comfortable and more city-friendly.

That’s the theory, at least. In practice, I have no idea. My time behind the wheel of the #1 was limited to its most fire-breathing model — the Brabus, which also scores its own suspension components — and soft is not a word that comes to mind once you’re strapped in behind its bright red seatbelt.

It begins with those bonkers power outputs, 315kW and 543Nm, which deliver genuine push-you-back-in-your-seat acceleration every time you stand on the go pedal.

Better still (well, I think so, at least), is that activating its sportiest 'Brabus' mode also unlocks a deep Abarth-style burbling soundtrack that rises and falls with your inputs.

But like most performance EVs, you can also dial the drive experience right back. In its softer drive modes the #1 Brabus feels calm and comfortable and not overly reactive, which makes sense, given the only thing the Brabus mode changes is accelerator sensitivity.

The result, though, is a car that you can tootle around in silently when you want to but hides a nuclear weapon under your right foot when you want to unleash that part of its personality. 

Downsides? It’s got plenty of point-and-shoot power, but in the few corners we managed to find in it, it didn’t quite live up to the all-out-performance badge. There’s a bit too much movement in the body — a symptom of its near-2.0-tonne weight — and it doesn’t feel entirely engaging.

A couple of important caveats, though. We didn’t get long behind the wheel of the #1, and the dull-as-dishwater prescribed drive program revealed little about its true performance potential. So, we’ll have to wait until the model is properly through the CarsGuide garage to give you a deeper dive on this one.

Full credit to Smart on this one, because the #1 comes with a pretty stacked active (crash avoidance) safety tech list, and though our test drive was far from exhaustive, only the speed limit warning (which you can switch off) felt overly intrusive, with the rest just sort of humming away in the background.

The full package includes things like adaptive cruise control, lane keeping assist, traffic-sign recognition and the aforementioned speed limit warning. There’s also AEB, along with seven airbags, all of which has earned the #1 a five-star Euro NCAP safety rating.

Servicing any hybrid can be a bit more expensive thanks to the presence of two propulsion forms.

In any case, the Sealion 8 requires routine servicing every 12 months or 20,000km.

Warranty is BYD’s normal six-year/150,000km cover, although there’s also eight years and 160,000km of cover for the EV battery.

BYD also claims its 'Blade' battery technology is among the safest in the business, and says the design resists damage (and, therefore, the risk of fire) better than the competition.

Warranty is a definite soft spot, with LSH Auto offering five years or 150,000km, whichever comes first. For reference, other Chinese newcomers include Chery (seven years) BYD (six years) and GWM (seven years), while MG has just shifted to a 10-year warranty.

Still, service intervals are 12 months/20,000km, and you should be able to take your Smart to any LSH Auto Mercedes dealership (in Melbourne, Brisbane and Sydney) or either of the Smart dealerships in Sydney or Brisbane.

Service cost for the first four years averages $611 per workshop visit for the Pro+ and Premium (worth noting the fourth service is a big one) and $780 for the Brabus. Not particularly small numbers.
