Audi Q7 vs BYD Sealion 8

What's the difference?

Overall, changes to the Q7 aren’t quite revolutionary, but that’s okay because it was already a fantastic large SUV.

The fact Audi has kept the price around the same mark and introduced a cheaper entry-grade should be welcome news for prospective buyers.

But even the existing variants are capable and impressive family haulers… and now they’re just that little bit better.

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.

The phrase ‘evolution not revolution’ is applicable here, cliche as it is, with the Q7 having been given a Botox-style lift at the front end.

The standard matrix LED headlights have a higher lighting signature than before, with the lighting elements leading into the lines down the shoulder of the SUV.

The grille now features a hexagonal honeycomb insert, the vertical line styling is now a thing of the past and the functional side vents are a little more aggro.

Overall, it’s a sharper look that brings the Q7 up to date with Audi’s current design language, down to the more angular wheel choices.

At the rear, the new tail-lights are ‘joined’ via a chrome strip spanning the rear, and the lower bumper (with real exhaust exits) has had a refresh.

Audi’s new CI badging (or ‘corporate identity’, pretty sexy stuff) is also present, which includes a new typeface for the ‘Q7’ badge at the rear, which is no longer italicised and is separate from the red ‘S line’ rhombus.

The four rings badge is also flatter and is white with black outlines, rather than a three-dimensional chrome badge.

Inside, the changes are more than skin-deep. In fact, the skin is the same, you’d be hard pressed to notice anything different about the Q7’s interior between pre- and post-facelift without diving into the electronics.

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.

Audi has changed the layout and added new apps in the main 10.1-inch multimedia touchscreen, though fortunately it still has shortcuts to all the Big Dogs in terms of functions: media, navigation, phone, etc.

On top of that, everything is still in big, easy-to-see (and press) blocky buttons on the main screen.

The 8.6-inch screen below also still has climate controls readily available, and there are still physical buttons for a bunch of functions including drive modes.

The wide 12.3-inch driver display also remains familiar, though now has a higher resolution and more functionality in terms of on-road help and safety - which we’ll come to later in this review.

Aside from the tech, ‘spacious’ is an understatement when it comes to the big Audi’s cabin. In the front seats especially, the Q7’s central tunnel and dashboard are easy to reach without feeling like an enclosure as they wrap around the front passengers.

However, if I had to level one criticism at the usefulness of the Q7’s front row, it would be that despite there being physically plenty of room, storage is at a premium. 

For something this big, there aren’t many places to put items that aren’t your phone or a drink. 

There are door card holders for bigger bottles, some space for small items, and the cupholders of course, but the space under the central armrest including the phone charger is stingy.

Fortunately, the second row is not lacking space and is modular in its adjustability. Occupants can move seats, adjust their angle, and even sort out the middle seat separately. 

Depending on how high up the variant chain you go, separate climate controls for the middle row and the panoramic sunroof help create a comfortable and roomy feeling.

The second row can also be tucked up behind the front row for easier access to the third row, which (if the second row is slid forward a tad) is just spacious enough for an average adult to be relatively comfortable for a short trip. 

The third row seats are able to be folded or raised with switches that are accessible from the side doors or the (electric) tailgate, where there’s also a switch to lower or raise the rear suspension by 55mm to aid loading.

On that, the Q7 has a claimed luggage capacity of roughly 295L with all seats up, 780L with the third row folded down and 1908L with the second row lowered.

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.

BYD will offer the Sealion 8 in three trim levels, starting with the front-drive Dynamic at $56,990, before on-road costs, then moving to a pair of all-wheel-drive variants, the first with the same Dynamic trim level at $63,990 and the range-topping Premium AWD at $70,990.

The Dynamic trim level on both the front-wheel drive and the all-wheel drive variant gets you three-zone climate-control, air vents in both rear rows, full connectivity including wireless Apple CarPlay and Android Auto. There’s also wireless phone charging. The Dynamic specification also takes on 20-inch alloy wheels and there’s full LED lighting as standard.

Pony up for the Premium trim and you make the switch to 21-inch alloys, a 21-speaker sound system and even a massage function for the first two rows of seats. The Premium also includes a head-up display for the driver.

Not as easy to quantify is the level of plush inside the cabin. There are lots of soft-touch surfaces and the whole interior design looks pretty fresh and modern and well put together. But more than that, there’s a bit of design flair that makes the BYD feel perhaps a bit more expensive than it really is. That’s not an easy thing to pull off. But it seems to work here, even in the entry-level Dynamic trim.

Against the competition, the Sealion 8 can't match the similarly specified Chery Tiggo 8 on price, even though on performance and EV range, the Tiggo 8 and the entry-level Sealion 8 are quite similar. The more expensive Sealion 8 Premium, meanwhile, lines up pretty neatly on price with the Kia Sorento S PHEV. But that vehicle can't get close to the epic straight-line performance of the BYD.

The four drivetrain options for the Q7 line-up are split between the two ‘grades’, with the 45 TFSI and TDI powering the 'entry-level' cars and the 50 TDI and 55 TFSI as the feature-packed variants.

The most affordable option is the 45 TFSI, which runs a 2.0-litre, four-cylinder, turbo-petrol engine making 185kW and 370Nm.

Like all variants in the Q7 range, the 45 TFSI engine powers all four wheels via an eight-speed automatic transmission. Audi claims the 45 TFSI will hit 100km/h in 7.3 seconds, if that’s your thing when it comes to three-row SUVs.

The rest of the line-up is powered by different versions of the brand’s 3.0-litre V6, all turbocharged, and all with 48-volt ‘mild hybrid’ (MHEV) tech aiming to increase efficiency.

The 45 TDI is, of course, a turbo-diesel 3.0-litre V6 that makes 170kW and 500Nm, also sending power and torque to all four wheels via the same style transmission. Audi says this one knocks over 100km/h in 7.1 seconds.

Similarly, but with more power and torque, the 50 TDI is also powered by a turbo-diesel unit as the name suggests. This one puts out 210kW and 600Nm, making it likely the best choice for towing and such even though all V6 variants boast a 3500kg braked towing capacity. The 50 TDI’s figure to hit 100km/h is a claimed 5.9 seconds.

Finally, the 55 TFSI makes 250kW and 500Nm, and boasts a 5.9-second claimed 0-100km/h time.

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.

As you might expect, diesel versions of the Audi Q7 are claimed to use less fuel than their petrol counterparts, so let’s start with those. 

The 45 TDI boasts a claimed 7.0L/100km consumption figure, while the 50 TDI is a little higher at 7.1 litres. Both have 75-litre fuel tanks, and should therefore theoretically get more than 1000km out of a fill.

On to the petrol models, the four-cylinder TFSI 45 has a claimed 9.3L/100km efficiency figure and the V6 TFSI 55's number is 9.0L/100km.

Given the nature of the driving and groups sharing cars during the launch event, we’ll wait until we’re next in a Q7 for a longer time before doing our own efficiency test.

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.

Aside from the mild-hybrid now standard on the Q7’s V6 models, there’s not a whole lot to report on in terms of new tricks or surprises from behind the wheel.

But that’s okay, because it means the Q7 remains a supremely comfortable and capable large SUV.

Our test route consisted of plenty of rural driving, with a combination of surfaces that would in some family haulers see the suspension and maybe even steering show cracks in their ability - but the Q7 remains composed.

Given its weight and size, it can feel a little hefty around sharper corners, but the Q7 in these variants (i.e, not its performance-focused SQ7 sibling) isn’t built to be hustled like that.

It feels like the kind of air-suspended loungeroom-on-wheels that would be at home barreling down the autobahn at 180km/h and being completely undramatic about it.

Still, this model shares some moving parts underneath with the likes of the extremely capable Porsche Cayenne, and while the Q7 isn’t quite a giant hot hatch, the sound foundations shine through dynamically.

Of course, when it comes to powertrains, there isn’t really a wrong answer, each engine fits a purpose.

If you’ll ever need to tow (and you can at up to 3500kg braked), the low-down steady urge of the 50 TDI is probably your best bet, but even the 45 TDI is a solid choice for long-range motoring.

The petrol models will better suit those in city situations, and while they never feel truly urgent, the 55 TFSI isn’t without some impressive push for something of this size.

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.

Any family car needs to be safe, so BYD has thrown the kitchen sink at the Sealion 8 in terms of its active and passive safety gear. That starts with nine air-bags including full-length curtain side bags and a centre-front airbag to help prevent head clashes.

There’s also a 360-degree camera on all grades, front and rear parking sensors, and the full line-up of current driver-assistance functions including autonomous emergency braking, lane-keeping assistant, rear-cross-traffic alert and assistance, blind-spot monitoring, driver attention monitoring and a tyre-pressure monitoring system.

To that lot, you can add adaptive cruise-control, traffic-sign recognition, adaptive headlights, front and rear collision warning, anti roll-over systems and hill-hold functions. It’s also worth mentioning that the overhead camera system is very, very good with a clear, crisp display and no processing delay.

The driver-attention monitoring seems to behave itself better than some of the over-active systems other makers specify, but the lane-keeping assistance function is still far form perfect. To be fair, it is less aggressive than some such systems and the intervention is more subtle, but the recued aggression seems to be packaged with lower sensitivity. As in, the cameras seem to sometimes miss a critical white line, particularly if its faded or less than freshly painted.

There are also ISOFIX child restraint tether points in both the second and third rows, as well as seat-belt warnings for every position and an electronic child-safety switch for the doors.

The Sealion 8 is yet to be crash tested locally, so no ANCAP star rating is available.

Audi’s five-year/unlimited kilometre warranty is pretty standard for a premium brand, but five years of free roadside assist and the ability to add a package to extend the warranty both add a little extra to the deal.

For the Q7, a five-year servicing plan is $3820, while the $4370 'Audi Advantage' plan adds two years to the warranty, two more services, and two more years' roadside assist.

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.
