BYD Sealion 8 vs Xpeng G6

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.

You never know quite what to expect when you jump into the first model from a brand-new brand, but the XPeng G6 was a pleasant surprise. And at this price, with these features, it should really give Tesla Model Y shoppers something to think about.

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’s more than a little Tesla Model Y in the XPeng’s exterior design, with the two sharing the same kind of soft-edged, swept-back SUV styling. 

It helps make the XPeng look familiar and inoffensive, and while I wouldn’t go so far as to call it ground-breaking, I think it has enough exterior flourishes to break up the body work, and I don’t mind the way it looks, and the way it sits on those big alloys.

Inside, it’s a spacious and pretty stylish space. This giant screen is super responsive, and is easy enough to navigate, with the key functions (like climate) glued to the bottom of the screen so you don't have to paw through menus to access them. The idea begins to fail when you have Apple CarPlay or Android Auto active, though, as you have to revert back to the car's home screen to access anything.

The XPeng uses its steering wheel controls to access air-con fan and temp controls as a kind of shortcut, but confusingly they change to distance adjustment when you’ve got the cruise control on. An easier, and much better solution would be to bring back buttons.

I also don't love the stalk-style gear selector, which doubles as a cruise control activator, and, with a double pull, as your autonomous helper. It just feels super old-school in a vehicle this modern.

What is a massive win though is the driver screen. Tesla fans can scream minimalist aesthetics all they want, but the drive experience is simply better when you can see your speed and other key info right in front of you.

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.

At 4753mm in length, 1920mm in width and 1650mm in height, the XPeng fits into the fast-growing mid-size electric SUV space. 

And it ticks a lot of practicality boxes, like with its 571-litre boot, swelling to 1374 litres with the seats folded. But its real party trick is in the back seat, where the space is properly massive. 

I have another mid-size SUV, powered by a petrol engine, at the moment and our baby seat presses against the back of the passenger seat. In this it feels like I could fly a kite in the space between them.

It’s the same for passengers, too. Honestly, the real estate on offer is massive, and that includes for the middle-seat rear passenger, where the lack of a bulky tunnel eating into legroom means adults can sit there comfortably.

There's a pull-down divider separating the back seat that's also home to two cupholders, and there are twin USB connections, as well as air vents (though no temp controls).

There's no spare tyre, though, which means fiddling with the repair kit should you get puncture, or waiting for roadside assist.

Okay, first things first – what the hell is XPeng? It's been around for about 10 years in China, but only made its way to Australia last year. It was founded by some former car company execs and tech tycoons — one of whom is telecommunications billionaire He Xiaopeng, which is where that name comes from.

Anyway, this one is the XPeng G6, which launched in Australia with two trims – the Standard Range, which is $54,800, before on-road costs, and the one we’ve tested, the Long Range, which is $59,800. The difference is in the battery size, of course, but we’ll get to that in a minute. 

As of now, the new Model Y can be ordered for $63,400 for the Standard Range or $73,400 for the Long Range, which makes the XPeng a whole heap cheaper.

Outside, you get LED lighting all around (including the DRLs), a massive glass roof, auto door handles, an auto-opening boot, a V2L connection, which allows you to use your XPeng’s battery to power whatever you plug in and big 20-inch wheels wrapped in Michelin rubber.

You also get some cool high-tech features, accessed through the XPeng app, like the ability to drive your car out of tight parking spots remotely.

Inside, there are synthetic-leather seats that are heated, a heated steering wheel, dual-zone climate, a massive 18-speaker sound system (with speakers in the headrest), wireless charging and two very handy screens — a responsive 15-inch central screen with Android Auto and Apple CarPlay, and a 10.2-inch digital dashboard.

There’s also more safety stuff than you can shake a crash test at, but we’ll come back to that in a second.

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.

This G6 is a rear-wheel drive affair, with a single electric motor housed at the rear axle. It produces 190kW and 440Nm in Standard Range form or 210kW/440Nm in Long Range guise, which don’t sound like massive numbers — especially given the 2.0-tonne-plus weight of this XPeng – but it gets up and moving just fine.

The 100km/h sprint is a claimed 6.2 seconds, while the top speed is 200km/h.

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.

The Long Range version of the G6 nabs a 87.5kWh battery (compared to 66kWh in the Standard Range), unlocking a claimed driving range of 570km. 

The official power use figure is 17.5kWh/100km, but I did a fair bit of driving on all sorts of roads and my number was more like 14kWh.

When it does come time to charge, the G6 is set up for 280kW DC fast charging which means, should you find the right fast charger, a 10-80 per cent charge should arrive in just 20 minutes. Home charging will take a lot longer, of course – we’re talking overnight plugged into a regular wallbox.

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.

How much you love your time behind the wheel of the XPeng G6 comes down to what you're looking for from your mid-size electric SUV.

Speed and sportiness? There's not much of either. But it does serve up tons of space and technology, surprising refinement and a calm and cosseting ride.

And I think you can mount a pretty solid argument that all of that is pretty important in a mid-size SUV, more so than the ability to carve corners.

I did some solid driving in the G6, including a round trip from Sydney to the start of the NSW South Coast, taking in every road type and surface imaginable, and XPeng proved super comfy, pretty quiet and very, very easy the entire time.

Sure, it's not one of those EVs that makes the scenery blur when you put your foot down. Its outputs and acceleration are a bit more user-friendly than that. But it also doesn't ever feel underpowered, with the plenty of poke away from the lights and even some in reserve for freeway overtakes at 110km/h.

The steering, even in its 'Dynamic' mode, is fairly soft, and you can never magic away the weight of the XPeng in corners, where that compliant suspension does allow for some roll, but it also doesn't feel entirely disconnected from the road below in that disconcerting way some vehicles can.

So, if comfort is mission critical in your SUV space, the XPeng delivers.

Oh, and I know that big screens aren't that uncommon these days, but the multimedia unit in the XPeng is a treat. It's super fast, even when scrolling across maps, and it's relatively user friendly, too.

The XPeng G6 wears a maximum five-star ANCAP safety rating from assessment in 2024, owing mostly to a flood of active safety features that arrive as standard, including AEB (with pedestrian, backover, cyclist, motorcycle and crossing detection), lane departure warning, lane keep assist, speed sign recognition, driver monitoring and more.

But it could also lay claim to a unique record – the first Chinese EV in which the safety systems don't make you want to make you pull your hair out with their incessant chiming and bonging.

Only on the freeway, where an intermittent chiming incorrectly warned me I was leaving my lane, were the safety systems at all overzealous. Otherwise, they were entirely liveable.

If a crash is unavoidable, the airbag count runs to seven (dual front, front side, side curtain and front centre) and multi-collision brake is standard, to minimise the chances of a secondary crash following an initial impact.

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.

I'm scoring the regular warranty offering here, which is five years or 120,000km, with the battery covered for eight years or 160,000km. Keep an eye out for deals, though. At the time of writing XPeng was offering a 10-year warranty on both, for example.

Service intervals are 12 months or 20,000km. The cheapest individual service is $238, but over five years the total cost is $2064, averaging out to more like $410 per year.
