Mitsubishi ASX vs BYD Sealion 8

What's the difference?

There is no question the new ASX is a much better car to drive than the model it replaces. This one is actually fun behind the wheel. The tech represents a massive upgrade, so too does the interior design and practicality. The fact is, it’s a much more expensive car than the old ASX. It is a European built and designed small SUV with loads more tech and features so when you consider that, the pricing makes more sense.

Regardless of the previous model, this new ASX impresses. It’s not perfect - the LS is missing too many items, no hybrid, slightly firm ride - but it’s now a genuine rival for higher quality rivals in the small SUV segment. If the ASX is in your price bracket, it might be time to add it to the consideration list.

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 look of the new ASX is not a huge surprise given it’s based on the second-generation Renault Captur that launched in 2021. Actually the ASX we get is the mid-life facelift for the ASX/Captur twins in Europe, so the design has been refreshed.

At 4238mm long, 1797mm wide, 1585mm tall and with a 2639mm wheelbase, the new ASX is 127mm shorter, 13mm narrower, and 55mm lower than the original, but the wheelbase is only 31mm shorter.

It has a round almost bubble like quality to the exterior design, and not in a bad way. The redesigned front end has Mitsubishi flavour thanks to the ‘Dynamic Shield’ front-end signature, while the sleek headlights and black and chrome grille give off an almost menacing look.

C-shaped tail-lights at the rear flank a massive ‘Mitsubishi’ badge and the lower cladding ensure there’s no doubt this is an SUV.

It’s a handsome car and should get some attention on the road.

Inside, it’s not the last word on interior design, but it’s well laid out and functional. It’s definitely another massive leap over the old model.

At the launch there were no LS grades to drive, but the Aspire comes with cool grey cloth trim and roofliner that adds a nice contrast to the darker plastics and finishes. It’s more vibrant than the top-spec Exceed which has an all-black interior with leather-appointed seats.

The top two grades feature a floating console where the gear shifter is housed (a standard shifter in LS, and notch-like ‘eShifter’ in Aspire and Exceed), while the big multimedia screen dominates the dash.

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.

This is an area the ASX excels in.

Up front there are loads of storage options. Multiple nooks for mobile phones, keys and other items, and the Aspire and Exceed get a wireless charging pad and extra storage under the shifter.

The central bin isn’t massive but doesn’t need to be with all the other cubbies, and there is ample room for large and tall bottles in the door bins.

A pair of USB-C ports and a 12V port up front handle electronics.

Thankfully there are physical controls for climate control at the base of the multimedia screen. The other functions housed in the screen like vehicle information and connectivity options are logically laid out and the system is not overly complicated.

Opting for the Aspire or Exceed means you get the brilliant Google Built-in, which is exactly what it sounds like. It’s essentially the Google operating system but for your multimedia screen so you have in-built Google Maps, Play and Assistant. Log in to your Google account and all your favourite places show up on Maps, and you can also log into Spotify and the like. It's a great set-up.

The seats are supportive and well bolstered. Much nicer than the old ASX’s overly cushioned seats.

The second row has more space than you’d expect looking at the car. It’s not cavernous by any stretch, but clever touches like scalloped out front seatbacks and roofliner ensure decent leg, toe and headroom, even with the sunroof in the Exceed. However, three adults in the rear isn’t super comfortable - we tried. Kids should be fine.

Amenities include more USB-C ports, rear air vents (very rare in this category), storage for small bottles in the door, phone holders in the door arm rests, dual map pockets, but no central armrest, which is no great loss.

That rear pew is comfy and more supportive than the old ASX. And it has a neat party trick. You can slide the entire row (via the base) forwards by up to 16cm, making for more cargo space in the boot. It also folds 60/40 split and when the boot floor is in its highest setting the seats fold flat, aiding loading.

Yet another clever feature is the split level boot. It features under-floor storage that adds a handy 183 litres to the cargo capacity.

With all seats in place Mitsubishi says the cargo space is 484 litres, which is 23 per cent more than the old model. If you slide the rear seat forward as far as it goes that increases that figure to 616L. And if the second row is folded flat the capacity is 1596L.

Interestingly, despite having space for one under the bottom boot floor, a spare wheel (even a temporary one) is not a standard feature. Instead the ASX comes with a tyre repair kit and offers a temporary spare wheel as part of its accessories offering for $750. If you’ve got the space for a spare wheel, why not make it standard? Especially when Mitsubishi is a popular brand in regional and rural areas.

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.

For now, all grades of the new ASX use the same 1.3-litre four-cylinder turbocharged petrol engine offering up 113kW of power and 270Nm of torque. That’s up on the old 2.0-litre naturally aspirated unit’s 110kW/197Nm.

This is paired with a seven-speed dual-clutch transmission driving the front wheels only, so there’s no all-wheel-drive version.

Mitsubishi is looking into the mild hybrid and full hybrid versions that are offered in Europe but not confirmation on those as yet.

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 new ASX consumes 6.4 litres of fuel per 100 kilometres on the combined cycle and emits 142 grams per kilometre of CO2.

That’s a decent figure for sure, but not quite as frugal as the 1.3-litre Nissan Qashqai, which manages 5.8-6.1L/100km.

The ASX drinks 91 RON fuel and has a 48-litre tank which makes for a theoretical driving range of about 750km.

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.

Look, it’s fair to say the original ASX was not a driver’s car. Reliable? Yes. Spacious? Absolutely. Great value? You bet. But fun to drive? Not so much.

So it’s good news then that the new-gen ASX is much more engaging to drive. I quite enjoyed the current-gen Renault Captur the last time I drove it, and the underpinnings of the ASX are the facelifted version of that Captur.

The 1.3-litre turbo-petrol unit might not be ultra quick off the mark, but it is sprightly and really comes alive when you’re at speed. It also has a decent engine note.

I've recently driven another Renault model with basically the same powertrain but it suffered from dreadful lag - a combination of a turbocharger and a dual-clutch transmission.

I had expected the same of the ASX, but there’s little lag to speak of. And the transmission is much smoother in this application. It doesn’t hold gears or do anything DCTs are known for, which is a lovely surprise.

Steering is sharp enough and the feel can be adjusted in the settings. Aspire and Exceed grades come with Comfort, Sport and Perso mode, which is for personalisation.

Ride quality is fine on smooth roads but big pot holes and other bumps are felt in the cabin. It is a European car, so no surprise that it’s been tuned for a more European experience. It’s not so firm it’ll dampen the drive experience, but it could be a touch more supple.

On that, the ASX has not undergone a local ride and handling tuning program like the one its larger Outlander stablemate has benefited from.

That doesn’t mean you can’t have fun in the ASX - you can. It handles high-speed bends on country roads surprisingly well, with more grip than you’d expect. There’s a little body roll but nothing dramatic.

More time behind the wheel is needed, but the tight chassis means the ASX likes a corner.

The cabin has better insulation than the outgoing model but it’s still not the most hushed small SUV money can buy. But it’s another element that’s far from a dealbreaker.

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.

Mitsubishi's standard warranty is five years or 100,000km, but if you service your car exclusively at a Mitsubishi dealer, it extends to an impressive 10 years or 200,000km.

You’ll also get 10 years of roadside assistance and capped-price servicing. The servicing schedule is every 12 months or 15,000km.

Service pricing starts from $349, but bigger services every four years or 60,000km will cost circa-$1000. The average price of a service across the 10 years is $568, or the total overall is $5686.

Mitsubishi has an extensive network of 185 dealers across Australia and many in regional areas. So service coverage is among the best in the country.

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.
