Renault Scenic E-Tech vs BYD Sealion 8

What's the difference?

The Renault Scenic E-Tech is lining up against some heavy-hitting competitors, but Renault Australia admits it has one top of mind - the Kia EV5. The Kia’s a quality package and if you’re in the market for a mid-size electric SUV, you’ll no doubt have it on your shopping list. And you should have a look at this slightly smaller car, as well. It has the refinement, practicality and safety to stand up confidently in a rapidly expanding segment.

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.

There are some design tips of the hat to Scenics past in this latest electric version, including blacked-out door pillars and a recognisably angular C-pillar treatment.

But despite the fact it debuted at the Munich IAA Motor Show in late 2023, from its slimline headlights and jagged grille to its sculpted flanks and saw tooth rear end, this fifth-generation Scenic looks contemporary from every angle.

A highlight is the large Renault diamond logo sitting at the centre of a faux upper grille, surrounded by a multitude of the same elongated hexagon shape as a cool recurring graphic, the pattern merging neatly into the headlights.

Speaking of which, the LED beams can be set to produce an elaborate welcome sequence as you approach the car.

The interior feels slick and screen-rich but not at the expense of user-friendly physical controls for audio, ventilation and other commonly used functions.

Recycled fabric on the dashboard and headliner looks and feels good while doing its bit to suppress cabin noise.

Speaking of which, the Scenic is Renault’s poster child for the use of recycled materials in its construction and end of life recyclability.

Everything from ferrous components consisting of 37 per cent recycled materials to a bonnet and doors made of up to 80 per cent recycled aluminium.

The dashboard cowling is made from kenaf, a plant fibre similar to jute; the steering wheel cover is 51 per cent bio-sourced; the cockpit uses 26 per cent recycled plastic; the storage bins in the door panels are 45 per cent recycled fibre, the floor mats are 54 per cent recycled plastic bottles and the seat upholstery is 100 per cent recycled fabric. The list goes on and on, but you get the idea.

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.

In terms of how it all works in practice, at just under 4.5m long, close to 1.9m wide and less than 1.6m tall with a 2785mm wheelbase, the Scenic is more compact than the larger BYD Sealion 7 or Zeekr 7X, for example.

But there’s plenty of breathing room up front, with the centre screen angled towards the driver enhancing the cockpit feel for the one doing the steering.

There are large carpeted bins in the doors with room for bottles and a lidded storage box between the seats doubles as a centre armrest. That lid slides forward by 70mm to cover a small storage cubby under the front of it, which is a handy trick.

Locating the gear selector on the right-hand side of the steering column liberates extra space for a centre cupholder and large console storage bin. There’s a generous glove box and a wireless smartphone charger under the centre screen includes a rubberised base and two lugs to stop devices sliding around. Power and connectivity runs to two USB-C ports and a 12-volt socket.

Moving to the second row, sitting behind my 183cm driving position, while toe room is a little tight (with the driver’s seat set low down), there’s heaps of leg and headroom as well as enough shoulder room (and foot room thanks to a flat floor) for three adults on short to mid-length trips. A pair of adjustable centre air vents is also a welcome inclusion.  

Storage includes door bins (again with room for bottles), large and device-sized pockets on the front seat backs and the pièce de résistance is the evocatively named ‘Ingenious armrest’, which includes a storage area and two cupholders at the base of articulated horizontal arms that allow passengers to mount a phone or tablet at various angles in rubberised slots for joint or solo viewing.

It is, indeed, ingenious and four USB-C plugs (two in the armrest, two near the air vents) mean back-seaters won’t be short of power options.

Boot volume with the rear seats upright is useful at close to 545 litres (VDA), expanding to around 1670L with the 40/20/40 split-fold second row lowered. A power tailgate is standard across the range.

There are bag hooks, tie-down anchors, lighting and a 12-volt socket back there, although for V2L (vehicle to load) functionality you’ll need an accessory adapter to plug into the charge port.

Maximum braked trailer towing capacity is a handy 1100kg, but there’s no spare tyre, only a repair/inflator kit, which isn’t good enough.

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.

Like its Megane E-Tech sibling, the Scenic E-Tech uses an excited synchronous motor which Renault says is more efficient than the more commonly used permanent magnet type, with the bonus that it uses no rare earth materials.

The entry-level Scenic E-Tech Techno's fitted with a 60kWh NMC battery. Its electric motor transfers 125kW and 280Nm to the front wheels and Renault claims a 0-100km/h time of 8.6 seconds.

The Techno Long Range and top-spec Esprit Alpine pack an 87kWh battery and a more powerful motor, raising outputs to 160kW/300Nm and lowering the 0-100kmh sprint time to 7.9 seconds.

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.

Official energy consumption numbers for the combined (urban/extra-urban) cycle are close between the two powertrains at 16.3kWh/100km for the Techno and 16.8kWh/100km for the Techno Long Range and Esprit Alpine, which are bang on average for the class.

Range for the standard Techno is 430km, which is at the lower end of expectations for a medium electric SUV but adding the bigger battery pushes that number out to 625km, which is much healthier and useful day-to-day.

On the launch drive program, which took in some urban but mostly rural B-road running, we saw an average consumption figure of 17.1kWh/100km in the Esprit Alpine, which is pretty good in those conditions.

The car’s 400V electrical architecture allows for DC charging at up to 130kW for the entry model and 150kW for the bigger-battery variants.

At that speed, claimed 15-80 per cent charge times are 32 and 37 minutes, respectively. Not the best, not the worst. AC charge capability is 11kW on all models and a Mode 3 charging cable is included.

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.

Renault says the entry-grade Scenic Techno will accelerate from 0-100km/h in 8.6 seconds with the more powerful Techno Long Range and Esprit Alpine lowering that number to 7.9sec. So, it’s quick without being scary fast.

It’s certainly nippy in traffic and at the risk of stating the bleeding obvious, quiet. Even in the context of premium EVs the Scenic is quiet and refined.

Suspension is strut front, multi-link rear and the car feels super planted. The launch drive took in some reasonably rapid twisting corners and there’s no hint of lateral movement in the car. Body roll is minimal, too.

Tyres are energy-efficient Michelin e.Primacy (Techno - 205/55x19 / Esprit Alpine - 235/45x20) and the steering is quick with a relatively low number of turns lock-to-lock. It’s never jerky or too sharp. Rather, it means the car starts to turn into a corner the instant you apply steering lock.

That said, the feel between your hands on the wheel and the front tyres on the road is less than intimate.

There are four drive modes - ‘Comfort, ‘Eco’, ‘Sport’ and ‘Custom’. None of them adjust the suspension tune, it’s more about accelerator response and we found Comfort delivers the best blend of right-foot urgency and overall composure.

Most of the braking you’re going to do will be courtesy of the regenerative system and there are five levels, adjustable via steering wheel paddles, including the most aggressive single-pedal mode.

The one-pedal setting pulls the car up nice and progressively and if you do need to use the physical brakes, they’re ventilated discs all around. Some bite on initial application, but even on downhill corner sections, leaning on them quite hard, they perform well without drama.

Under the heading of miscellaneous observations, you can sense the ADAS (Advanced Driver Assistance Systems) including functions like lane-keeping assist doing their thing occasionally, but it’s all quite subtle, which is a good thing.

The Esprit Alpine’s sports front seats remained grippy and comfortable after a couple of hours behind the wheel. And it’s worth noting the Scenic’s relatively compact 10.9-metre turning circle helps in slow-speed manoeuvring.

Speaking of which, some of the modes in the audio system and external warning sounds for pedestrian safety have been designed by French composer and performer Jean-Michel Jarre, noted for his electronic, ambient-style music. Hats off to Renault for commissioning him.

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.

Warranty is five years/100,000km, which is well off the market pace with many competitors at seven, eight and up to 10 years conditional. The battery warranty at eight-year/160,000km matches the market.

Roadside assistance is included for five years, service is recommended every 12 months/30,000km and fixed price servicing is available at a reasonably sharp average of $325 per workshop visit for the first five years.

Renault has 52 dealers across the country covering major cities and key rural areas.

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.
