Renault Megane vs BYD Sealion 8

What's the difference?

If the Renault Megane RS Trophy is your dream car let me say this: there’s no overarching reason that I’d say you shouldn’t go ahead and buy it. 

But with so much amazing competition in this part of the market, it’s hard to put it ahead of its rivals. And it’s going to be even harder for it to stay high on the contenders list as more new metal arrives in the coming years.

There’s no denying the value the BYD Sealion 8 Premium offers as it packs a lot in for the price. Its efficiency and inoffensive looks add up to a good package and reflect what it does well. That said, the underwhelming driving experience and clunky media system are noticeable. Whether they're deal breakers is up to you.

The Megane RS Trophy’s dimensions don’t really communicate just how chunky it really is. At 4364mm long on a 2670mm wheelbase, 1875mm wide and 1435mm tall, it is pretty conventional in terms of size for the segment.

But it packs a lot of style into that size. I for one love those broad hipped wheel-arches, the signature LED headlights and chequered flag lighting signature at the bottom of the bumper, and the bright, eye-catching colours available really just ram the message home that this isn’t your average Megane.

I could happily leave behind the red flecks on the wheels, which look a bit too blingy and not quite ‘lightweight racing-spec’ to me. But they obviously appeal to a certain buyer - maybe someone who wants a bit more drive-by flair, as opposed to track-day talking points.

The Trophy model builds upon the Cup variant, using the same chassis and hardware under the skin, and therefore running the brand’s 4Control four-wheel steering and a mechanical Torsen limited slip diff. More on that in the driving section below.

Exterior design and styling are one thing - but you probably spend more time sitting inside your car than just admiring it from a distance. How does the interior of the RS Trophy stack up? Check out the interior images to make up your own mind.

The Sealion 8 is a big unit, and its design leans more towards soft and rounded than sharp. There’s a sense of restraint with its pillowy panels, smooth curves and flush door handles all contributing to a clean, almost clinical look.

The 21-inch wheels add a bit of presence, as does the full-width LED light bar with its braided design. But overall, it doesn’t try too hard to stand out. It’s inoffensive - clean and easy on the eye, but it stops short of having any sense of identity.

Inside, the cabin carries that same restrained approach. There’s black leather upholstery, some interesting geometric detailing through the panels and speaker grilles and a generous use of soft-touch materials throughout.

The large displays and panoramic sunroof help lift the space, giving it a premium feel, but more importantly, it’s just a comfortable, easy place to spend time. Which, for a family SUV, arguably matters more than anything else.

The Megane RS Trophy’s cabin carries over some of the design cues from the exterior. It looks and feels like a hot hatch should.

There’s a lovely part-Nappa leather, part-Alcantara steering wheel with paddle shifters and a ‘centre line’ marker - but some may lament the lack of a flat-bottom to the wheel, which is a current trend in the “trust me I’m actually very sporty” breed of cars.

The manually adjustable seats are very supportive though they are a bit firm, so those wishing for ultimate comfort over long distance trips might be left wanting. But there is good adjustment to the seats, and they’re heated, too.

There are some nice elements to the cabin including soft plastics on the dashboard, but the lower plastics - below the eye-line - are quite hard and not very pleasant. However, the inclusion of ambient lighting does distract from that, and add a bit of flair to the cabin.

The portrait-style media screen is fine most of the time, though it does take some learning. The menus aren’t as intuitive as you might hope, with a mix of on-screen buttons and off-screen touchpad-style controls that can be difficult to hit when you’re driving. We also had a couple of instances of glitching while using Apple CarPlay and Android Auto smartphone mirroring.

Storage is okay. There are shallow cupholders between the seats, a covered centre console bin, as well as a storage section in front of the gear selector that’s big enough for a wallet and phone, and bottle holders in the doors. 

In the rear seat there’s enough space for someone my size (182cm) to sit behind their own driving position, albeit with limited knee room and toe room. Headroom is good, and there are dual ISOFIX child-seat anchor points and three top-tethers for baby seats.

You’ll find a pair of small door pockets, two map pockets, and rear-seat directional air vents, which is nice. There’s a flip-down arm-rest with cupholders, too, and unlike some other high-price hatches with ambient lighting up front, the Megane gets LED light strips on its rear doors, too. 

The boot space is good in the Megane RS Trophy, with luggage capacity claimed at a healthy 434 litres. On test, the car fit all three CarsGuide suitcases (124L, 95L and 36L) with room to spare. Speaking of spare (ahem), there isn’t one: it comes with a repair kit and tyre pressure monitoring, but no spare wheel of any kind. 

Up front, storage and general usability are well thought out. There’s a handy shelf tucked underneath the centre console with two USB-C ports, while a tray above houses the fast wireless charging pad. You also get a sunglasses holder, two cupholders and decent-sized bottle holders in the doors, so it’s easy to keep things organised.

Seat comfort is a highlight, and the overall layout is clean and easy to live with, but the same can’t be said for the multimedia system. While the graphics are sharp and the touchscreen is responsive, functionality isn’t always its strong suit. Wireless Apple CarPlay and Android Auto are included, but CarPlay required reconnecting on every drive during testing and the digital radio and phone calls experienced noticeable signal dropouts. It’s the kind of friction that chips away at the day-to-day experience and starts to feel out of step with how polished the rest of the cabin is.

There’s also a heavy reliance on the screen for core functions. Climate control is integrated, which is fairly standard, but so too are things like headlight controls. It might suit those who are used to navigating everything through a screen, but needing to dig through menus to adjust something like auto high beam on the move feels like a step too far. Bring back buttons.

The second row is where the Sealion 8 really leans into its family-friendly brief. Space is generous, with enough width to comfortably accommodate three adults and the flat floor helps here too. There are three top tether points and two ISOFIX mounts, while charging is covered by a USB-A and USB-C port.

Amenities are a standout. The outboard seats mirror the front with heating, ventilation and massage functions, which quickly become a favourite, alongside dedicated climate controls, roof-mounted air vents and multiple cupholders. A set of sunshades would round things out nicely, but it’s otherwise a very accommodating space.

Access to the third row is less impressive. The manual slide and tilt mechanism feels a little heavy and fiddly to operate and the space itself is best reserved for kids. In practice, that means younger passengers will likely take the path of least resistance, as mine did and simply climb over the second row instead.

Amenities are fairly basic, with directional air vents and cupholders, but there’s no charging provision back there. You do, however, get two top tether points and ISOFIX mounts, which will be a plus for larger families.

Around the back, the boot is a practical, usable space with a wide opening and flat loading floor. With all three rows in place, there’s 270L on offer, which is enough for a few school bags or a grocery run, expanding to 960L with the third row folded. There’s no spare tyre, just a repair kit, which may be a consideration for regional drivers. A 12-volt socket and powered tailgate round things out in this grade.

The BYD Sealion 8 range is relatively straightforward, with two grades on offer and the base variant available with a choice of two drivetrains. For this review, we’re in the flagship Premium AWD, which is priced from $70,990 before on-road costs.

It lines up against the Chery Tiggo 9 Super Hybrid at $65,430 driveaway, the Kia Sorento GT-Line PHEV from $71,130 before on-roads, and the Mazda CX-80 P50e Azami, which stretches up to $87,950 before on-road costs.

On paper, the Sealion 8 Premium doesn’t quite undercut the Chery on price or match its claimed 170km (NEDC) electric-only range, but it’s not far off, with a still-impressive 152km (NEDC). And when you look at the broader package, it starts to make a fairly strong value argument, particularly against its other key rivals.

The 'Premium' badge isn’t just for show, either. Equipment is generous, with highlights including a fixed panoramic sunroof with an electric sunshade, leather-appointed upholstery, a heated steering wheel, and heated, ventilated and massaging seats not just in the front, but for the outboard seats in the second row as well - a feature that hasn’t gone unnoticed by my nine-year old.

Technology is a clear focus. There’s a 10.25-inch digital instrument cluster, a large 15.6-inch touchscreen multimedia system and a 26-inch augmented reality head-up display, alongside wireless Apple CarPlay and Android Auto, a 50W wireless charging pad and a 21-speaker DiSound audio system. BYD also includes 2GB of data per month for the first two years to support its 4G connectivity and over-the-air updates.

Practical touches round things out, with keyless entry and start, NFC card access and a digital key via the BYD app, a powered tailgate, vehicle-to-load (V2L) capability, rain-sensing wipers, sound insulation for the front doors and windscreen and three-zone climate control.

Engine specs matter if you’re talking about performance hatchbacks, and the Megane RS Trophy is no exception.

It has a 1.8-litre four-cylinder turbo-petrol engine that punches hard for its size, with 221kW of power (at 6000rpm) and 420Nm of torque (at 3200rpm). That’s for the six-speed dual-clutch automatic transmission, as was fitted to our test car. If you buy the six-speed manual, you miss out on a bit of grunt - it has 400Nm (at 3200rpm) and the same peak power.

In auto spec the RS Trophy “300” offers higher figure vs the Sport and Cup “280” models (205kW/390Nm), and more engine performance per litre of capacity than the Focus ST (2.3-litre: 206kW/420Nm), Golf GTI (2.0-litre: 180kW/370Nm; TCR 2.0-litre: 213kW/400Nm), and even the Golf R (2.0-litre: 213kW/380Nm). 

All Megane RS models are front-wheel drive (FWD/2WD) and no Megane RS is all-wheel drive (AWD). The Trophy and Cup models both get 4Control four-wheel steering, which is an interesting aspect of the drive experience. More on that below. 

There are multiple drive modes to choose from, including Comfort, Neutral, Sport, Race and the configurable Perso mode. These can alter engine, transmission, throttle, traction control, exhaust noise, fake engine sound and steering sharpness - but not suspension, because the dampers aren’t adaptive units. 

The BYD Sealion 8 Premium is all-wheel drive and pairs a 1.5-litre, four-cylinder, turbo-petrol engine with two electric motors, one on each axle. Combined outputs sit at a hefty 359kW and 675Nm, which comfortably out-muscles its key rivals.

Those figures do drop back to a more modest 110kW and 220Nm when running on the petrol engine alone.

Performance is strong for a large family SUV, with a claimed 0-100km/h sprint time of 4.9 seconds. You can toggle between pure EV and hybrid modes depending on the drive, which adds a layer of flexibility that suits short daily trips and longer highway runs.

The claimed official combined fuel consumption for the Megane RS Trophy is 8.0 litres per 100 kilometres. That’s for the EDC auto model as tested. The manual is said to use 8.3L/100km.

You might achieve that if you drive gently, though over my testing - which incorporated hundreds of kilometres of highway and country road driving, as well as a few spirited stints and some urban snarls - I saw a return of 10.8L/100km at the pump.

The Megane RS requires 98RON premium unleaded, and the fuel tank capacity is 50 litres. 

Charging is handled via a Type 2 CCS port, with support for up to 11kW on AC and up to 74kW on a DC fast charger. BYD claims a 30 to 80 per cent recharge can be done in as little as 20 minutes under ideal conditions.

The 35.6kWh lithium iron phosphate (LFP) battery is a standout, delivering a claimed electric-only driving range of 152km on the NEDC cycle. That figure is on the optimistic side compared to WLTP testing, but even with that in mind, it remains an impressive number for a plug-in hybrid of this size.

With a full battery, the combined fuel consumption is rated at just 1.0L/100km, translating to a theoretical driving range of over 1000km. Real-world results will vary depending on how often you’re able to charge and the type of driving you’re doing, but after a week that included a fair stretch of highway driving, my trip computer was showing 6.3L/100km. Overall, it’s a solid result, particularly for something with this level of performance.

The Megane RS Trophy has the ingredients to be an all-time legendary hot hatch, but they don’t work together well enough for it to be a truly great car to drive.

That is, they don’t work together on public roads. I didn’t get a chance to sample the RS Trophy at the track, and I’m sure that may well alter some of my opinions. But this was a review focused around everyday driving first and foremost, because - unless you’ve got quite a fleet of cars - you’ll be spending a lot of time in mundane motoring in your Megane RS, too.

Other hot hatches in the segment manage to combine big power and torque with immense traction and steering prowess. The Megane RS used to, as well.

But this new version seemingly has some issues harnessing the grunt, and the 4Control four-wheel steering system simply isn’t as rewarding as it should be.

I had several instances where the traction on slippery surfaces was lacking, while even in the dry I noticed distinct torque steer and the Bridgestone tyres struggled to cope under hard acceleration. That’s despite the fact the Trophy gets a mechanical LSD.  

Further, that four-wheel steering actually makes it pretty hard to judge the behaviour of the car at times, with an artificial feel to it that just doesn’t do it justice. There will be some who say that the four-wheel steering - which can angle in the rear tyres to help you pivot in corners more adeptly - is excellent. But I’m not one of them. I really found it hard to predict this car’s behaviour. I never really gelled with it.

At the very least there’s a non-interventional lane keeping assist system, which emits a pulsing sound through the speakers rather than actively vibrating or adjusting the steering. 

The ride is unapologetic in its firmness – although, if you’re across the history of RS Megane models, that is to be expected for a Trophy chassis. It can be tiring on longer road trips especially if the surface isn’t great.

While it is extremely fast in a straight line - 0-100km/h is claimed at just 5.7 seconds - it wasn’t as quick through corners as I was expecting it might be, and that comes down to its four-wheel steering mostly, along with a lack of usable traction at times. It simply isn’t as connected to the road as the previous RSs have been. 

It was also a bit laggy then lurchy at lower speeds when taking off from a standstill, such is the nature of the dual-clutch in stop-start situations. 

To put it bluntly, I didn’t enjoy this car anywhere near as much as I thought I might. It just isn’t as pure a driving machine as I’ve come to expect from the RS brand. Perhaps I should aim to try it on a track!

On-road performance is where things become a bit of a mixed bag. There’s no denying the Sealion 8 Premium is quick and it leans more heavily into its EV character than many large plug-in hybrids. It’s quiet in hybrid mode and responsive off the mark, which makes it easy to keep pace in traffic and overtake when needed. For something of its size, it also does a good job of masking its weight on the move.

Regenerative braking is offered in two levels, but even the stronger setting feels fairly mild. The upside is smoother low-speed driving, with none of the abruptness you sometimes get in hybrids, and it does still recover a decent amount of energy, particularly on longer descents.

Where it falls short is in its overall dynamics. The steering and suspension are tuned for comfort, which results in a soft, slightly floaty feel on the road. It’s not unpleasant and around town it actually suits the car’s brief, but there’s a noticeable lack of feedback and control if you’re expecting something more composed.

Visibility and driver positioning also take some getting used to. The forward view is decent, but the pillars are quite thick and it can be difficult to find a driving position that doesn’t feel a little enclosed.

Judging the edges of the car isn’t always intuitive, and while the 360-degree camera is clear, its perspective can feel slightly off. Objects tend to appear much farther away than they are, which isn’t the most reassuring combination when you’re trying to manoeuvre in tighter spaces.

The BYD Sealion 8 is yet to be tested by ANCAP and therefore remains unrated at this stage. That said, it comes equipped with a comprehensive suite of safety features, along with nine airbags including side chest airbags for the front and second rows.

Standard equipment includes seatbelt reminders for all seating positions, front and rear parking sensors, driver attention monitoring and alert, tyre pressure monitoring, traffic sign recognition and autonomous emergency braking. It also features front and rear collision warning, blind-spot monitoring, rear and front cross-traffic alert and side exit assist.

On the road, however, some of the active safety systems are less polished in execution. The adaptive cruise control can feel abrupt when slowing down and slow to regain speed, while the steering assist can be overly reactive through corners. Lane keeping also lacks consistency, with the system not always engaging as expected.

For families, child seat provision is strong, with four ISOFIX anchor points and five top tether mounts across the cabin, along with child presence detection.

The Renault Megane RS range is covered by a five-year/unlimited kilometre warranty, which adds some peace of mind for owners.

Further, the service intervals are generous, at 12 months/20,000km - though the brand states the Megane RS is actually “subject to adaptive servicing requirements” as the oil condition sensor may trigger a service check requirement prior to the standard intervals.

Unlike other Renault models with a five-year capped price servicing plan, the Megane RS is only covered for three years/60,000km. The service costs for the EDC dual-clutch auto models are higher than the manual versions, due to replacement transmission oil being needed (adding $400 to the first service). 

The costs for the first three services are: $799 (12 months/20,000km); $299 (24 months/40,000km); $399 (36 months/60,000km). Consumables beyond those service intervals include: every 24 months or 20,000km - air filter replacement ($49) and pollen filter replacement ($63); every 48 months or 60,000km - accessory belt replacement ($306). Spark plugs are included at no cost, due every 36 months/60,000km.

The car is backed for up to four years of roadside assistance when serviced within the Renault dealership/service network.

BYD offers the Sealion 8 with a six-year/150,000km warranty and an eight-year or up to 160,000km battery warranty. Both terms are competitive for its class.

Service is recommended every 12 months/20,000km with each workshop visit averaging a solid $596 for the first five years (year four is $1360). Accessing a BYD service centre is fairly easy as there are around 70 centres nationwide now.

BYD recommends premium unleaded petrol (95RON) to be used for the Sealion 8.
