Audi RS3 vs BYD Sealion 8

What's the difference?

The Audi RS3 is a special hot hatch and sedan I’m so glad I experienced before its five-cylinder engine is inevitably retired due to emissions regulations. Full of character and charisma, this car is far from a rational purchase, pitched at boy racers who don’t want to grow up just yet.

From a value perspective, too, while the asking price has crossed the six-figure threshold and the option prices add thousands, it’s still much cheaper than the Mercedes-AMG A45 S. Make of that what you will.

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.

Audi has made some subtle tweaks to the RS3 that has somehow made this snarling hot hatch look even angrier.

Up front there’s a new fascia featuring more open sections, which in turn improves air flow. A black styling package is now standard so it almost looks like the entire front is open and ready to eat you alive.

The matrix LED headlights now have a darkened finish which adds to the menacing look. There are new signatures, including a special chequered flag one for the RS3 which looks top notch.

Around the side it surprises me just how much wider the front is compared to the rear. Both have big, muscular haunches, but it shows this hot hatch is a bit of a bulldog. I’m a big fan.

These haunches stand out even more when you opt for the new Daytona Grey Matte exterior paint. While the extra $11,400 for the privilege makes me wince, it looks sexy on this car.

The standard 19-inch ‘Y-spoke’ alloy wheel design remains unchanged from the pre-update car, though there’s a new, optional ‘cross-spoke’ design that looks delicious (and tricky to clean).

At the back there’s still the classic RS dual exhaust tip motif which looks mean and it’s surrounded by a new black rear diffuser with a motorsport-inspired vertical red reflector in the centre.

The new LED tail-light signature with the vertical slats is so clean and neat. It looks particularly great in low-light situations or at night.

Inside, the biggest change is the new RS steering wheel with the flat top and bottom. As standard it’s wrapped in perforated leather, but with the optional RS Design package it’s wrapped in 'Dinamica' synthetic suede. I much prefer the standard leather-wrapped unit as the Dinamica likely won’t last in the long run, especially if you’ve got clammy hands.

Other changes include more interior ambient lighting on the door cards through small slits, as well as a new shift-by-wire gear selector. The digital instrument cluster and touchscreen multimedia system set-up remains unchanged which is no bad thing because they look fantastic.

It’s disappointing Audi has stuck with an extensive use of piano black on the centre console because this gets dusty and grimy very quickly, and then can get scratched easily when wiped clean. It now also features on the steering wheel buttons, which are frequent touchpoints.

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.

The RS3’s standard sport front seats are deliciously comfortable and offer plenty of electric adjustment. This means people of any size and stature should be able to find their desired seating position.

Thanks to the electric lumbar there’s also a massage function for the front seats. This is pretty cool to flick on and relax into, but I wish the massage was a little stronger.

While the new steering wheel looks cool interacting with the buttons on it can be a bit of a hassle. They’re touch-sensitive but do have a satisfying click if pressed harder.

There were moments where I accidentally clicked on the buttons during intensive track driving as my hands were at the nine and three o’clock positions. Not the best thing when you’re meant to be focussing.

The digital instrument cluster offers so much configuration you won’t know what to do with yourself. There’s even a new rev counter design especially for the RS3 which looks very cool.

Moving across, the touchscreen multimedia system is classic Audi. It’s easy to navigate around and hard to get lost in the sub-menus. There’s also wireless Apple CarPlay and Android Auto connectivity which is virtually a given now.

While you need to use the touchscreen for a number of features, I appreciate how Audi has retained so much physical switchgear up front. It’s particularly handy to have physical toggle switches and a small digital display that’s separate from the touchscreen for the climate control.

Another piece of physical switchgear I like up front is the rotary dial for the media controls on centre console. It’s much like an iPod, allowing you to change the volume if you rotate your finger on it like a click-wheel. Major throwback vibes.

In terms of storage up front, it’s decent but not outstanding. There are two cupholders, a wireless phone charger, a centre console box as well as a lockable glove box.

Moving to the second row, it’s clear it’s more for the sake of it, rather than having a space you’d want to use all the time. At a leggy 182cm tall, I have minimal legroom behind my own driving position.

With headroom, it’s adequate in the hatchback and not great in the lower-slung sedan. I need to kink my neck in the latter to fit, which isn’t comfortable.

The second-row bench seat is comfortable, offering enough support for short-to-medium trips. I wouldn’t want to get stuck back there for too long, however.

In terms of amenities, there are air vents mounted on the back of the centre console with a dedicated third zone of climate control, two USB-C ports, nets on the seat backs as well as a fold-down centre armrest with cupholders.

At the back there’s a power tailgate for the hatchback, however the sedan only has a power-opening boot lid. This means you need to manually shut it, which isn’t uncommon for sedans.

Boot space in the RS3 is a weak spot due to all the componentry for the all-wheel drive system and the tricky rear clutch set-up. There’s only 282L for the hatch and 321L for the sedan, which isn’t much.

In reality, however, the boot space is still usable. It’s fairly square and there’s barely any boot lip, meaning you can slide things in and out with ease.

Boot-related amenities include a netting system to keep things from sliding around, a light, some hooks and a 12V socket. There’s also a parcel cover for the hatchback.

Unfortunately there’s no spare wheel of any kind under the boot floor in the RS3 as this is where the 12V battery lives. Instead there’s a tyre repair kit. This isn’t uncommon in performance cars, though it’s disappointing if you frequently travel in the country, away from tyre repair shops.

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 Audi RS3 is still powered by a 2.5-litre turbocharged five-cylinder petrol engine which produces an unchanged 294kW of power and 500Nm of torque.

This is mated to a seven-speed dual-clutch automatic transmission with drive sent through an all-wheel drive system.

Audi claims both versions of the RS3 can do the 0-100km/h sprint in just 3.8 seconds, which is technically 0.1 seconds faster than a Mercedes-AMG A45 S. Top speed is electronically limited to 250km/h.

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.

The Audi RS3 sedan is claimed to consume 8.2L/100km, whereas the RS3 hatch is claimed to consume 8.3L/100km, both on the combined (urban/extra-urban) cycle (ADR 81/02).

Both body types come with a 55L fuel tank and require a minimum of 98 RON premium unleaded petrol.

During my testing I saw an average of 9.6L/100km according to the trip computer. We did around 200km of higher speed driving heading east out of Melbourne, including some spirited sections.

Our on-test figure translates to a range of 570km on a full tank of petrol.

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.

Spoiler alert, it’s a cracker.

Starting up the RS3, you’re instantly aware you’re behind the wheel of something special. Audi has made the start-up more “emotional” with this update and also “optimised” the exhaust flap control for more five-cylinder growl across a wider rev range.

When you’re on the boil, this five-cylinder sounds so fantastic. It’s the clear centrepiece of this car and I’m so happy Audi has continued to offer it.

However, thanks to the addition of a petrol particulate filter (PPF) with this latest-generation model it sounds a little muted in everyday driving. Call me a boy racer, but I want more noise.

Staying on the engine, it’s full of character and gets this small hatch and sedan moving along with ease. Even though the outputs are unchanged with this update, it’s still more than enough; 0-100km/h in 3.8 seconds shows it's more than enough.

The seven-speed dual-clutch automatic transmission in this car keeps the acceleration feeling relentless with snappy gear changes at a moment’s notice. It’s particularly fun taking control of moving between the ratios with the paddle shifters.

In slow-moving traffic, however, the dual-clutch can get a little lost and stuttery, which is a classic characteristic of this kind of transmission.

As standard the all-wheel drive system remains neutral, keeping the front and rear balanced and in check. However, if you flick to the ‘Dynamic’ drive mode you get more rear-biased action which is fun when you exit a corner with some extra heat.

There’s also still a ‘RS torque rear’ drive mode which is essentially a drift mode. Unfortunately we didn’t get to sample this during the launch program.

Additionally, there’s an ‘Individual’ mode that allows you to choose your own destiny. You could spend hours here fine-tuning your desired drive mode which is both great to see but complete nerd-core.

Like the pre-update car, there’s an electronically controlled multi-disc clutch on the rear axle which actively splits the torque between the rear wheels. However, it’s been "optimised" to allow for quicker cornering.

While this is hard to gauge without testing the pre-update and current car back-to-back, the RS3 is so dynamic it feels like you only scratch the surface on public roads. Thankfully we got to see how far we could push it on Haunted Hills, which is a fantastically complicated hill climb circuit in eastern Victoria.

In terms of the steering, there’s a progressive rack as standard which ramps up the steering intensity the more you turn the wheel. In practice, this means the lock-to-lock ratio is very short, making it easy to link up tight corners.

It also makes it easy to navigate tighter driving scenarios, like parking, though it disguises how wide the turning circle is. Expect to do three-point turns fairly often.

For the suspension, the RS3 has adaptive dampers set-up that generally errs on the sportier and firm side. There is a ‘Comfort’ mode which irons out some bumps, but larger road imperfections still transmit harshly into the cabin.

It’s also worth noting at higher speeds there’s a considerable amount of road and tyre noise that comes into the cabin. Thankfully the Sonos sound system does a great job at drowning this out.

Lastly, the safety systems in this car are generally user-friendly, though the lane-keep assist can be a little too hands-on, especially on narrow roads with poor lane markings. Thankfully you can switch this off by pressing and holding a button on the end of the indicator stalk.

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.

Like all Audis, the RS3 is covered by a five-year, unlimited-kilometre warranty. There’s also five years of roadside assistance.

Logbook servicing is required every 12 months or 15,000km, whichever comes first.

You’re able to purchase a five-year pre-paid service package for $4010. That averages out to $802 per service, which seems like a lot until you see how much Mercedes-AMG charges to service an A45 S.

RS3 owners can also purchase two-year packages to extend the warranty, roadside assistance and servicing coverage. This allows new RS3 owners to have warranty coverage for up to nine years and it’s transferable to future owners.

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.
