BYD Sealion 7 vs Peugeot 408

What's the difference?

The BYD Sealion 7 Performance is well-priced and well-equipped. It more than holds its own against its mid-size electric SUV rivals. It has great motor outputs and it handles comfortably on the road. There's a lot to like here but some of the technology needs to be tweaked.

The Peugeot 408 GT Hybrid delivers heaps of standard equipment and safety tech for what is now a much more competitive price. It’s also super fuel-efficient, which is right for these turbulent times, offers thoughtful practicality and the wagon-fastback-crossover-SUV look is striking. The price paid for miserly economy is a peaky small-engine powertrain and the ownership promise isn’t exactly class-leading. That said, it deserves consideration in its new, even more competitive under $60K mid-size SUV segment.

It may be named after a sea lion but it doesn’t resemble the blubbery cuteness of the creature itself. However, its sleek dynamic styling and performance outputs do call forth some of the creature's water prowess. 

This prowess is hinted at by the 20-inch alloys which are fitted with Michelin tyres and red brake calipers. There’s some Porsche-like design notes in the wide swoopy nose and LED headlights. The rear is also quite handsome with its long LED band strip and narrow window giving it a sporty silhouette.

Head inside and the Performance showcases the best BYD cabin I've sampled. There are no strange accents or panelling like there are in the Atto 3. This proves that BYD can do premium well.

The quilted leather upholstery feels supple underhand and the sports seats with integrated headrests reminds you what it can achieve in a sprint.

The swoopy design is carried over inside with the door panels. The dashboard is simply styled but headlined by an enormous 15.6-inch display that can rotate between landscape or portrait mode. Some may liken it to an iPad but it works.

The panoramic sunroof keeps things bright and cheerful but there are some simplistic elements that are hard to ignore. Like the lack of buttons, minimalist mirror cover design on the sunvisors and a rather plain-looking centre console.

Everything else flows and my favourite feature inside is surprisingly the lever door handles! They're functional but cute.

Peugeot Design Director Matthias Hossann has been guiding the brand’s look and feel since 2020 and the result is a recognisable approach across the range with enough flexibility to give each model its own personality.

Recurring themes include the dramatic, fan-like grille with body-colour elements, narrow angled LED daytime running lights (DRLs) slicing through the outer edges of the nose and sinister tapered headlights set into the front corners.

The rear end maintains the visual drama with a stacked, angular treatment sectioning off the ‘Claw Effect’ LED tail-lights (the Peugeot brand mark is a Lion), chamfered mid-section and chunky bumper.

And among what increasingly feels like a mass of same-same newcomers the 408’s sloping turret and high, wide haunches give the car a distinctively sporty fastback look.

The interior is classy and clean although the almost uniformly grey colour palette is unrelenting.

The two-tier dash adds visual interest and a combination of sweeping curves and clean, straight lines around the cabin lift the tone. Nappa leather trim with the ribbed seat centre panels using perforated hide also looks classy.

But then we come to the ‘iCockpit’ instrument display and steering wheel combination. It’s based on the idea that reducing the size of the steering wheel and lowering its position while flattening its top and raising the location of the instrument binnacle is a better solution than the traditional look-through-the-steering wheel approach.

It doesn’t work for everyone and it doesn’t work for me. As noted in previous Peugeot reviews, after more than a decade in existence various members of the CarsGuide editorial staff continue to struggle with the arrangement, while others love it. 

For me, the wheel feels too low, yet the top of it obscures the lower part of the instrument panel. While it may work well for others I see it as the answer to a question no one was asking.

The cabin has space, space and then more space. Passenger comfort is all but guaranteed with the available leg- and headroom in each row.

The functions for the electric front seats means it's easy to find a comfortable position. Door apertures are wide for each row and despite a relatively low 140mm ground clearance, it's still an easy SUV to slide in and out of.

Technology looks great and the large 15.6-inch multimedia display is what catches your eye first. Graphics are sharply rendered and the touchscreen responsive. There's a lot of information and menus embedded into the display which means it's a system that will take you a beat to get used to.

It's not unique but the in-built voice assistant rarely works as it should and needs some work. Also, because of the lack of buttons and dials, all functions are accessed via the screen. I don't like this because it tends to draw your eyes from the road far more often than it should and some functions - like the heat and ventilation for the front seats - are buried in a few menus.

There is wireless Apple CarPlay and Android Auto but there are some gremlins that need to be ironed out. The connectivity is easy enough but the steering wheel mounted phone control didn't access Apple CarPlay. So, I couldn't hang up my phone call properly, it would instead access the Bluetooth phone menu and dial my last call. I had a few 'butt' dials this week because of it.

Storage is on par with the Performance rivals and up front the burden falls across the large glovebox and middle console but there is also a shelf underneath the centre console for bigger items, like a handbag. There are two phone cradles, although only one offers wireless charging, and two height-adjustable cupholders two drink bottle holders and small storage bins.

In the rear, you get two device pockets and a map pocket on the back of each front seat. There is a fold-down armrest with retractable cupholders and a small storage pocket (think Kindle-size) and there are storage bins in each door.

The boot capacity is a decent 500L and the floor can be adjusted to two heights, one offering a level loading space. There is also a frunk storage of 58L for any cables or random bits you don't use often. Under the boot floor there is also enough room for cables and the tyre repair kit. The powered tailgate can be access via your keyfob as well.

For a flagship grade, I would have expected a few extra amenities in the rear, like climate control and sunshades but it does have directional air vents, reading lights and a USB-A and C port.

At close to 4.7m long, around 1.9m wide and a bit less than 1.5m tall with a 2790mm wheelbase, the 408 sits in the middle of the typical mid-size five-seater footprint.

Ample room in the front, although the lower section of the two-tier dash protrudes a fair way towards the driver and front passenger and the centre console is broad so it feels snug rather than airy.

Storage includes generous door bins with room for larger bottles, a lidded (and illuminated) bin between the seats that doubles as a centre armrest, two cupholders in the console with an oddments tray ahead of them and a decent glove box with an extra pocket built into the lid.

Switching to the rear, sitting behind the driver’s seat set for my 183cm position, there’s loads of leg- and headroom and enough width for three adults when required and more than enough for a trio of up to mid-teenage kids. Centre rear is less of a short-straw position, too, thanks to a relatively low and flat central tunnel.

The lack of a fold-down rear centre armrest is a miss mainly because it means there are no cupholders in the rear. But there are decent door bins with a space for smaller bottles, netted map pockets on the front seatbacks and a storage cubby at the back of the front centre console.

Speaking of which, individual air vents in the back of that console are a welcome addition.

 The boot is large for the class at 508 litres (VDA) with the rear seat upright and 1583 litres with the 60/40 split-folding backrest folded down. The power tailgate (with foot sensor and pedestrian detection) also makes life easier.

Other thoughtful touches include four load tie-down anchors, a netted pocket on the right-hand side, elasticised straps on the left-hand side, specific lighting and a pair of bag hooks.

Power and connectivity options include two USB-C sockets, a 12-volt outlet and a wireless phone charging pad in the front, another two USB-Cs in the back and a second 12V plug in the boot. So no problems with charging capacity for phones and other devices.

Maximum braked trailer towing capacity is a useful 1300kg (750kg unbraked) but we have to put a big black mark against provision of a repair/inflator kit rather than a physical spare. Not good enough for the Aussie market. 

The previous plug-in version of the current 408 Hybrid was a 1.6-litre, turbo-petrol, four-cylinder paired with a relatively large electric motor and cost-of-entry sat at $67,990, before on-road costs.

A shift to this car’s mild-hybrid powertrain, built around a 1.2-litre, turbo-petrol, three-cylinder engine matched up with an appreciably smaller battery and electric motor coincided with a 15 per cent ($10,000) price reduction to $57,990, BOC.

Convenience or consequence? Either way, it’s opened up a new competitive set with the focus shifting from the likes of the Lexus NX, Mazda CX-60 PHEV and Volvo XC60 to a fresh batch of sub-$60K rivals.

Think Honda CR-V e:HEV RS ($59,900, drive-away), Hyundai Tucson AWD 1.6 Hybrid Premium ($58,350, BOC), Kia Sportage GT-Line HEV FWD ($57,370, BOC), Nissan X-Trail Ti e-Power 5 seat AWD ($58,215, BOC), Subaru Forester AWD Hybrid Touring ($55,990, BOC) and the Toyota RAV4 XSE Hybrid AWD ($59,015, BOC).

Suddenly the Peugeot’s included features list sits in a new context and aside from the performance and safety tech we’ll get to shortly, standard equipment highlights include dual-zone climate control air, full-grain Nappa leather seat trim, a leather-trimmed (heated) steering wheel, Alcantara door trim, 3D satellite navigation and 10-speaker 690-watt Focal audio (with digital radio) as well as wireless Android Auto and Apple CarPlay.

Then there’s power-adjustable driver (eight-way) and front passenger (six-way) seats that are also heated with a ‘multi-point’ massage function, keyless entry and start, a 10-inch digital 3D instrument panel, a 10-inch multimedia touchscreen, auto LED matrix headlights, eight-colour ambient lighting, chrome trimmed pedals, a power tailgate, heated power-folding exterior mirrors, a panoramic glass sunroof, 19-inch alloy wheels, auto rain-sensing wipers and more. 

Then you can add over-the-air updates, access to remote services via the ‘MyPeugeot’ app and ‘Ok Peugeot’ voice recognition.

That’s an impressive basket of fruit for an under-$60,000 car. 

The Performance is all-wheel drive and is fully electric with dual motors, a squirrel cage induction motor located at the front and a permanent magnet synchronous motor at the rear. Together they produce up to 390kW of power and 690Nm of torque.

This gives the flagship grade a 0-100km/h sprint time of just 4.5 seconds. There’s obviously ample power to be had here which will delight EV fans who like that tummy-falling sensation when accelerating.

The Peugeot 408 Hybrid is powered by a 1.2-litre, turbo-petrol, three-cylinder engine producing 100kW at 5500rpm and 230Nm at 1750rpm.

This compact, all-alloy, direct-injection unit works in concert with a single 15.6kW/51Nm 48-volt electric motor integrated into the six-speed dual-clutch auto transmission and energised by a 0.9kWh lithium-ion battery.

Drive goes to the front wheels only and Peugeot claims a 0-100kmh sprint time of 9.4 seconds.

The Sealion 7 Performance has a blade battery with a large 82.56kWh capacity which supports a 456km WLTP driving range. This isn’t terrible for city drivers but a regional driver will likely want a longer range. BYD includes a portable charging cable with the model.

Charging is sorted via a Type 2 CCS charging port which accepts up to 11kW on an AC charger and up to 150kW on a DC charger. On a 150kW DC charger, you can go from 10 to 80 per cent in as little as 32 minutes and that increases to more than eight hours on an 11kW AC charger. All of the figures are quite good and help with the general day-to-day convenience.

The official energy consumption figure is 20.4 kWh per 100km but after doing a healthy mix of open-road driving and city stuff, my average has popped out at 19.1kWh. I reckon it's a solid result for a ‘performance’ grade but I didn’t find the regenerative braking to be particularly strong on this model.

The 408 Hybrid’s official fuel consumption figure for the combined (urban/extra-urban) cycle is 4.5L/100km, the 1.2L turbo triple emitting 102g/km of CO2 in the process.

And it’s important to point out those official (ADR 81/02) numbers for the 408’s consumption and emissions are better than any of the direct competitors we’ve called out in the ‘Price & Features’ section above. 

Over a week of mainly city and suburban running with some freeway sections thrown in, we recorded an on-test average of 6.0L/100km. Impressive for a mid-size crossover weighing in at a bit over 1.4 tonnes.

Brim the 52-litre tank with minimum 95 RON premium fuel (ethanol blends not recommended) and using our real-world figure you can expect a handy driving range in excess of 860km.

The Performance grade offers plenty of power that is delivered wickedly quick without feeling overwhelming when you have to accelerate. You still feel in control, which is very important when you have outputs like this does.

The steering is responsive and light enough for quick lane changes. The general on-road handling is quite refined but there is more roll in corners than you’d expect and this is the only time the power can make the handling feel a tad wobbly.

Surprisingly, there isn't a one-pedal function and the regen braking isn’t particularly strong. It’s difficult to ‘creep’ forward in this in stop/start traffic where it can feel a bit jerky at times, so it handles best on the open road.

Visibility is mostly good but the rear window is narrow and a digital rear-view mirror would have been welcomed in this model. Suspension is sports-firm but forgiving over bigger bumps. 

The 360-degree view camera and surrounding sensors makes this super easy to park and honestly, you shouldn’t have any trouble manoeuvring the Sealion 7.

Even with the assistance of an electric motor in the transmission and a turbo on the engine, a 1.2-litre, petrol three-cylinder powering a more than 1.4-tonne five-seat car is always going to be an interesting equation.

And in practice, although the small triple’s peak torque (230Nm) is available from just 1750rpm it lacks the smoothness of larger capacity mild- and full-hybrid combinations. Especially at slower speeds, the powertrain feels relatively edgy and agitated.

Outright acceleration is fine (claimed 0-100km/h acceleration is 9.4sec) with decent mid-range pulling power for confident overtaking or decisive lane changing (a 15.6kW/51Nm boost from the motor playing its part) and the dual-clutch auto is a more polished example of what can be a fractious device. 

But engineering and tuning for maximum fuel-efficiency has an impact on driveability. For example, we noticed the air-conditioning system’s output softened at standstill, which led to some mild window fogging in stop-start traffic on a particularly humid morning. Haven’t seen that for a while. 

The strut front, torsion beam rear suspension delivers a compliant ride and responsive handling in classic Peugeot fashion. The steering in particular points accurately and provides good road feel. 

We’ve covered the intricacies of the i-Cockpit instrument and steering wheel configuration in the Design section as its shortcomings (for me, anyway) are more ergonomic than dynamic.  

The car is relatively quiet, thanks in part to sound-dampening acoustic glass and the Michelin e.Primacy tyres (205/55) which also grip persistently if you decide to slice through your favourite set of corners. Push the engine harder and it’s revvy note and exhaust rasp will start to make their presence felt. 

Regenerative braking is helpful and the physical brakes (ventilated discs and the front and solid rotors at the rear) are nice and progressive.

The front seats are firmer than the Peugeot norm but remain comfy enough and they provide enough side support to keep you well located. 

Despite the swoopy fastback design, all-around vision is surprisingly good and an overall length under 4.7m, an acceptable 11.2m turning circle, a clear reversing camera and a 360-degree camera view make parking straightforward. 

The 408 has a maximum five-star ANCAP rating from assessment in 2022 with active crash avoidance tech including Auto emergency braking (AEB) with pedestrian and cyclist detection, junction assist and backover detection, adaptive cruise (with stop & go), lane departure warning and lane keep assist, blind spot monitoring, traffic sign recognition, a 360-degree camera view, rear cross-traffic alert, forward collision warning, driver fatigue monitoring and tyre pressure monitoring as well as front and rear parking sensors.

If a crash is unavoidable there are six airbags onboard (front, front side and side curtain) but a front centre bag is notable for its absence. 

On the upside, an active bonnet helps protect impacted pedestrians from striking hard engine parts under the bonnet and multi-collision brake minimises the chances of subsequent impact after an initial crash. 

For child seats there are three top tether points across the second row with ISOFIX anchors in the outer positions.

The Sealion 7 is covered by a six-year/150,000km warranty which is good for the class. The battery is covered by an eight-year/160,000km warranty which is a normal term.

The Sealion 7 gets a 10-year capped price servicing but it’s expensive compared to some of its peers at $4157.

Servicing intervals are spaced at every 12 months or 20,000km, whichever occurs first.

Peugeot covers the 408 with a five-year/unlimited kilometre warranty, which is perilously close to sub-par in 2026 with an increasing number of brands at seven, eight and up to 10 years conditional. The battery warranty at eight years/160,000km matches the market.

Roadside assistance is included for five years, service is recommended every 12 months/15,000km and pre-paid servicing is offered across three-, four- or five-year plans, with the latter at $2070.

That’s a not insubstantial average of $414 per workshop visit, which Peugeot says will save you $893 compared to pay-as-you-go over the five years.

For reference, a Toyota RAV Hybrid service for any of the first five years is $260, although pricing steps up after that period.

Peugeot has a well established network of 31 dealers mainly covering major cities and key rural areas, primarily on the east coast. Currently, no presence in Tassie or the Northern Territory, while Perth and Adelaide are the only representation in WA and SA.
