Peugeot 408 vs BYD Sealion 8

What's the difference?

The Peugeot 408 GT plug-in hybrid features tech that could be improved upon and like all plug-ins, you get the best economy if you regularly charge it and that’s not always realistic. It is a little expensive compared to its rivals but sports a killer design that looks fresh and the cabin is roomy with nice features.

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.

There’s quite a lot happening with the design because of the mash-up of body styles. The long sleek body has sedan vibes but it sits high enough to tag itself as an SUV and the rear has that classic coupe pinching.

It won’t be everyone’s cup of tea but I like it. It's bold and different, which feels like a bit of fresh air in this SUV-heavy market.

The lights also set this apart from its Peugeot stablemates and look more refined, too. You can still see the remnants of the original ‘claw’ design in the tail-lights if you look closely but it's the long vertical DRLs at the front that give the design real edge. They resemble the fangs of a snarling cat (just too cool).

The sophisticated sleekness is extended to the interior where you find a cabin that is flush with high-end materials and soft touch points.

The curved dashboard, high-end tech screens and the mix of Nappa leather upholstery and synthetic leather trims definitely cement its grade position. While not a fan of the green contrast stitching myself, it does create an interesting focal point.

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.

Both rows have ample leg- and headroom for my 168cm height. Even my father, who is 183cm tall, felt comfortable in both rows.

The seats are comfortable and offer enough padding to be enjoyable on a long trip. The heat and massage functions on the front seats make the cabin experience feel refined but the massage function sometimes stops when the heat function is also on.

Individual storage is good for the class with the front getting some centre console storage spots, including a phone shelf, as well as a dual-opening middle console, glovebox and two cupholders. There are also a small storage bin and drink bottle holder in each door.

In the rear, there are directional air vents, two USB-C ports, map pockets and a drink bottle holder in each door but you miss out on cup holders, an armrest and other items you might expect for this grade level, like heated outboard seats or climate control.

The other charging options are solid with the front row getting two USB-C ports, a wireless charging pad and a 12-volt socket. There is another 12-volt socket in the boot.

The 10-inch touchscreen multimedia system looks great and you can customise your ‘buttons panel’ to the features you use most often, which is very clever. However, the system isn’t always responsive which gets very annoying - the seat functions in particular can be laggy.

The system does feature built-in satellite navigation and wireless Apple CarPlay and Android Auto but the multimedia system is too glitchy to truly charm.

The boot features a tyre puncture repair kit, relatively level loading space and 471L of boot capacity, which has been fine for all of my errands this week. You also get a hands-free powered tailgate, which is always handy.

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.

The 408 GT is a front-wheel drive that has an eight-speed auto transmission and is powered by a 1.6-litre turbo-petrol engine and an 81kW electric motor, which produce combined outputs of 165kW/360Nm. It can do a 0-100km/h sprint in 7.8 seconds. 

The switch between the electric and petrol components isn’t always seamless and you can feel some shudders as it flips between them at lower speeds but the power feels adequate for everyday driving.

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 official combined cycle fuel consumption figure is 1.5L/100km but that’s if you were recharging the car every time the electric range dropped out.

My real-world consumption sat at 5.5L after a mix of open-road and urban driving. I only charge it every other day as that’s realistic for my family life but like all plug-ins - you will get the best efficiency if you charge it regularly.

The 408 GT has a Type 2 charging port and a small 12.4kWh lithium-ion battery that can accept up to 3.7kW of power. You get up to 60km of pure electric driving range (but I only saw a top of 38km available) and on a domestic socket, you can go from zero to 100 per cent in around six hours.

On a 7kW or 11kW AC power charger, that drops to three and a half hours. So, it’s a tad slow to charge but worth it if you can leave your car on charge overnight.

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 408 GT has more than enough power to be a comfortable open-roader. You can keep your speed consistent on hills and it has enough gumption to cross traffic quickly in an urban environment.

Steering is responsive and the car is easy to manoeuvre in close quarters but the lane-keeping aid does severe corrections, so have your wits about you when you’re on the go because it can be a fright when the wheel starts fighting you.

With the ride comfort, there can be vibrations through the seats and steering wheel depending on the road surface and you’ll know about it when you hit a bump. It’s okay enough to not be classed as rough but it’s not as refined as you'd hope.

Despite the narrow rear window, the visibility is actually very good and it’s easy enough to park but the 180-degree camera system needs work.

You'll end up using the straight reversing camera because you need to ‘drive’ over the space for an image to pop up for the '180-degree' view and by the time it does, you’ve parked anyway!

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 408 comes with a usual warranty term of five-years/unlimited km and the battery is covered by an eight-year or up to 160,000km warranty.

You can pre-purchase three, four, or five-years worth of services, which all work out to be cheaper than the pay-as-you-go option. It costs $1200 (three-years), $1700 (four-years), and $2000 for the five-year plan.

On the five-year plan, services average $400, which is reasonable for the class. Servicing intervals are also good at every 12 months/15,000km, whichever occurs first.

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.
