BYD Sealion 8 vs Gac Aion V

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.

Candidly, I questioned the logic behind GAC entering the Australian market, especially now given the seemingly non-stop influx of other brands. How could it really hope to stand a chance against so many similarly priced and similarly equipped rivals?

Well, the answer is by providing a better product. The Aion V is simply a better package than many of its rivals, Chinese and otherwise, at least based on our initial impressions.

It combines value and practicality but also adds a level of driving comfort and manners its Chinese rivals can’t match.

Is that enough to guarantee success? Not at all, but it’s a strong foundation to start with and at least gives GAC a fighting chance to not get lost in the crowd.

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.

One of the most notable elements of the Aion V design is the absence of a ‘GAC’ badge on the front. That’s because, while all GAC models in Australia will be sold under the one name, in its native China there are several different sub-brands. GAC Aion is the ‘new energy vehicles’ brand, focused on electric vehicles (EVs), while the smaller Emzoom SUV is part of the more mainstream Trumpchi brand that offers internal combustion engine models.

It means the three cars sold initially, and even as the brand moves forward with its expansion plans, there will likely be stark visual differences between models because they are effectively different brands. In the same way Holden ended up with a mixture of Opel, Chevrolet and GMC products in its final years.

Having said all that, the Aion V itself is an inoffensive design. It’s not as generic as some of its rivals, with some design character around the headlights and silhouette, so overall it cuts a likeable figure without being particularly memorable.

Like so many modern cars, the Aion V has a very simplistic layout inside, with more screens and less physical buttons and switches to reduce cost and complexity. There’s an 8.8-inch digital instrument display and a 14.6-inch multimedia touchscreen in the centre on the dashboard.

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.

In terms of practicality there’s a handy space for a wireless smartphone charging pad, and that previously mentioned heated or cooled centre console box. Oddly, though, there is no traditional glove box. Instead there are just a pair of bag hooks ahead of the front seat passenger.

Space is good for a mid-size SUV, with a roomy front and respectable space in the second row. It would comfortably accommodate four adults, so would be a good option for families with older children.

As for the boot, it’s a generous 427 litres and has multiple adjustable floor heights available. Disappointingly, even though it has space for a spare, potentially even a full-size one, it only has a tyre repair kit. That might be fine in some markets around the world, but in the vastness of Australia, that is not the best option. Even a space-saver spare would be a better bet.

Starting with the basics, the Aion V is a five-seat electric SUV priced from just $42,590, before on-road costs, for the entry-level model.

Now, not too long ago an all-electric SUV for under $45K would be a revelation and would have made an impact on this market. But there are plenty of alternatives to choose from these days at similar money, including the Geely, Leapmotor and the BYD Atto 3.

Even so, at $42,590 for the entry-level Premium and $44,590 BOC for the more-premium-than-Premium Luxury variant, that’s still very competitive pricing.

For that money you get a well-appointed mid-size SUV, with even the base model equipped with LED headlights and tail-lights, 19-inch alloy wheels, a panoramic sunroof, heated and ventilated front seats, dual-zone climate control and a nine-speaker stereo.

Stepping up to the Luxury adds partial genuine leather seats, massaging front seats and a box in the centre console that can act as a fridge and a warmer, depending on your needs.

While neither the cheapest EV nor the best-appointed, the Aion V does a nice job of offering a compelling value proposition in its competitive set.

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.

Both the Aion V Premium and Luxury are powered by a 150kW/210Nm electric motor, which drives the front wheels. 

Aion doesn’t claim a 0-100km/h time, but it wouldn’t be quick, at least not in EV terms. If you’re looking for a ludicrously powerful electric car - this ain’t it. It’s a perfectly fine powertrain for the job at hand, but it won’t blow your socks off with its performance and will take more than eight seconds to run 0-100km/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 battery is 75.2kWh lithium-phosphate type, which provides a claimed range of 510km. Importantly, that figure is on the WLTP cycle, not the more lenient Chinese (CLTC) test protocol, so you could reasonably expect close to that target in the real world.

GAC claims it can accept up to 180kW charging speeds, which will get the battery from 10-80 per cent in just 24 minutes. 

It also has vehicle-to-load functionality, so you can draw power from the battery for tools or appliances if you need it.

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.

This is perhaps the area where the Aion V surprised the most. One of the most consistent qualities of these new Chinese-developed models is their incompatibility with Australia’s unique road conditions. They have a tendency to lack comfortable, controlled suspension and well-weighted and consistent steering.

That’s not the case with the Aion V, with GAC clearly taking the benefits from the partnerships it has with Toyota and Honda to learn what international markets prefer. Is this a clear standout, class-leading SUV dynamically? No. But it is above-average in the way it rides and handles.

The suspension is well resolved and feels comfortable to live with, while the steering is nice and direct, which will make navigating the cities, suburbs and open roads more easy and enjoyable. 

There is still some fine-tuning that could make it better, but overall the Aion V leaves a positive first impression. 

GAC is offering the same safety equipment across both models, which is a nice touch to avoid any need to compromise.

This includes full airbag protection for all occupants, front and rear parking sensors and a 360-degree camera system. 

There’s also a lengthy list of driver assistance features, including adaptive cruise control, autonomous emergency braking, forward collision warning, traffic sign recognition, emergency lane keeping assist, rear cross-traffic alert and door opening warning.

These systems could benefit from some real-world testing and calibration, because while better than some, they were still intrusive and annoying at times - most notably the driver attention monitoring.

ANCAP has not yet tested the Aion V, but it has received a maximum five-star rating from Euro NCAP, which typically carries over to the local body.

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.

The Aion V is covered by an eight-year, unlimited kilometre warranty which is well ahead of the mainstream pack, typically sitting at five years, unlimited km. The drive battery is also covered for eight years, 200,000km and roadside assist is included for five years. Recommended service interval and costs are still to be confirmed.

But one of the biggest challenges for all these new car brands is finding space in the Australian market - literally. If you want to sell a lot of new cars you need a lot of new car showrooms and if you want to keep customers happy, you’ll need enough service centres to keep cars on the road as much as possible.

GAC has plans to have as many as 100 dealerships in the next five years, but right now it has reportedly less than a dozen. That will make servicing problematic if you do not live in close proximity to a service centre. This isn’t the work of a moment either, with so many new brands fighting for dealership real estate and staff there are only so many places GAC can set up shop.
