Renault Arkana vs BYD Sealion 8

What's the difference?

The Arkana is a stylish alternative in a sea of same-same compact SUVs. It's relatively well equipped and has some hidden gems in its ownership and running costs that elevate it above some of the competition.

It’s not a bad thing to steer, either, but the lurchy dual-clutch could be a deal breaker for some.

The sweet spot is the Techno, which misses out on the Esprit Alpine’s special touches but represents the most bang for your buck.

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.

This update isn’t a massive overhaul of the Arkana, rather its “refreshing and enhancing” what was already there according to Renault Australia.

And this remains true with the car’s styling. Not much has changed on the outside except for a few minor garnishes and flourishes, especially on the Esprit Alpine variant.

The coupe styling isn’t for everyone. It’s more popular in Europe than Australia but if you want to stand out from the crowd it’s a good place to start.

The Arkana has curves in all the right places and its little grille made up of little Renault badge diamonds is a welcome addition in a world of wide mouth front ends. The C-shaped LED headlights and a large Renault badge add a bit of pop to its look.

The pinched rear end has LED lighting that runs from the tail-lights to the centre badge and Arkana is spelled out in big, bold letters.

The Esprit Alpine stands out with gunmetal highlights on the front bumper and the front and rear skid plates in the same colour. It also adds a Esprit Alpine badge below the side mirror and front door sill plates.

The Esprit Alpine has 'Tricolour' stitching in red, white and blue on the door trim and steering wheel, which is complemented by blue contrast stitching on the gear shifter, seats and centre console.

Cabin quality is variable. There are some nice feeling materials used on the dash and on the door trims but below eye level there are lots of hard wearing plastics. A big slab of faux wood running along the dashboard doesn’t feel as high-quality as you would like. The quality drops a bit in the back row, which is where carmakers often try to cut costs.

Solid white is the only no cost paint colour, but it is not available on the Esprit Alpine. Metallic white, blue, black, grey and red cost $750.

Buyers can also option a black roof for a two-tone look for $600.

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 Arkana isn’t a family SUV, but rather is pitched at younger couples and empty nesters. 

Up front there is great forward vision with a higher seating position than hatchbacks and sedans. Electronically adjustable seats and a manually moveable steering wheel means there’s a good seating position for pretty much everyone.

The seats are comfy and the multimedia screen and climate controls are easy to reach. The centre console has a wireless device charger, two USB-A charging ports and a 12-volt socket to keep various devices juiced up. 

Two cupholders take up most of the space with minimal storage space leftover. There are decent sized storage bins in the doors and a little net in the passenger seats footwell to stop small items rolling around. 

Back seat passengers have their own air con vents and USB charging ports, which is a welcome addition.

In the rear pew is where the Arkana’s stylish coupe-like design dents its practicality. The sloping roof shrinks the windows and reduces headroom, which makes it feel a bit gloomy compared to more boxy-shaped SUVs that makes it no-no for smaller kids.

The boot is a decent size, but it’s longer and lower than other SUVs, which is the price you pay for looking good. 

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 Arkana keeps the 1.3-litre four-cylinder turbocharged petrol engine from before. It makes 115kW and 262Nm and is paired with a seven-speed dual-clutch auto that drives the front wheels. 

That’s plenty of grunt for a car this size, but it’s let down by a glitchy transmission that hesitates a lot at lower speeds and doesn’t do its best work when asked to hustle, either.

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.

Efficiency is the name of the game with the Arkana’s little turbo engine. The French brand claims it drinks 5.9L/100km on the combined (urban/extra-urban) cycle but we averaged 7.5L/100km on our circa two-hour country road drive according to the trip computer.

The higher speed twisting and turning country roads we drove on aren’t conducive to low fuel use, though.

It has a 50-litre fuel tank and only requires cheaper 91 RON petrol, which is rare for little turbo engines that usually have premium tastes.

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 Arkana is a bit of a mixed bag on the road. Its engine is a nice little unit but the dual-clutch auto deflates the drive experience.

At lower speeds it hesitates and then gives too much oomph all at once, which can result in some wheel spin. It means you need to be mindful at T-intersections and when turning across traffic and feather the pedals. 

This is a symptom of most dual-clutch autos but the Arkana’s is less sophisticated than say ones fitted to Volkswagens, and the Arkana doesn’t have the meaty power and torque bands of performance cars. A conventional torque converter auto would suit it better.

The Arkana does some of its best work at higher speeds, where the dual-clutch is more decisive and it's an admirable highway cruiser. 

It isn’t a bad operator through the bends where it exerts excellent body control to minimise rolling. This is complemented by nice steering that is well weighted and accurate. Pedal feel is excellent with no woody or doughy feel to them.

The suspension is on the firmer side and you’ll feel some harsh bumps, especially over consistent smaller ones that it will crash over.

Its rear torsion beam suspension set-up is less sophisticated than the multilink arrangements found in an increasing number of competitors in the segment.

Road noise is noticeable at higher speeds. There's a fair bit of wind noise, too, but it was an especially windy day on our test drive.

The Arkana isn’t a sports car but is a stylish SUV for punting around town and facilitating weekend getaways, but there are other compact players that answer this brief better.

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.

There is one part of Renault’s ownership credentials that others can’t match.

Its service intervals are every 12 months and a whopping 30,000km, which is double the industry norm of 15,000km. 

If you need to do big kays such as a sales rep or rideshare driver might this will be extremely important.

Five years or 150,000km of capped price servicing visits costs $2385, which is one the expensive side compared to Honda, Hyundai and Toyota but is in the ballpark of similar-sized Kias and Volkswagens.

Renault covers the Arkana with a five year/unlimited km warranty - par for the course in the mainstream market - and five years of roadside assistance.

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.
