BYD Sealion 8 vs Mazda CX-9

What's the difference?

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 CX-9 is still a great option for families looking for a large SUV, even if it is starting to show its age as new rivals continue to launch with newer technologies.

That said, the availability of a luxury-focused six-seat configuration (Azami LE AWD) for the first time might be enough to convince some buyers to give it further consideration.

But for others who need the versatility of seven seats, this is still the CX-9 we’ve all come to know and love – but just a little bit better – particularly in its best-selling Azami AWD form.

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.

Given its latest update is relatively minor, the CX-9’s exterior largely looks the same as before, which, depending on your point of view, is a very good thing. As far as we’re concerned, it certainly is.

That said, train-spotters will notice some differences, with the GT SP (new), Azami and Azami LE (new) grades getting a refreshed grille that’s slotted and available in two grade-specific finishes unlike the insert their carryover Sport, Touring and GT siblings still have. 

And aside from the GT SP, Azami and Azami LE’s new sets of 20-inch alloy wheels (again in grade-specific finishes), the only other exterior change is the Azami and Azami LE’s larger-diameter chrome exhaust tailpipe extensions. Sporty!

Inside, the CX-9 has more changes in store, headlined by the new ‘floating’ 10.25-inch central display all but the Sport and Touring get (they stick with 7.0- and 9.0-inch units respectively).

The new set-up is powered by Mazda’s latest multimedia system, which is certainly an improvement over its predecessor, and a much needed one at that.

Worth noting, touch is not an input method, with the rotary controller on the centre console the only option, which is actually great for safety, so we’re all for it.

The Azami and Azami LE also get new quilted Nappa leather upholstery, which looks and feels great, and adds to the overall high-quality theme.

Otherwise, it’s pretty much business as usual, which is great because the CX-9 has always had a well-designed interior. Yep, if it ain’t broke, don’t fix it.

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.

Being an SUV that’s 5075mm long, 1969mm wide and 1747mm tall, practicality is arguably the most important thing for the CX-9, and with the option of six seats for the first time with the new Azami LE, it’s even more versatile.

All seven-seat grades have a 60/40 split-fold second row that manually slides and reclines the same as before, with only the Sport missing out on one-touch tumble operation, which makes accessing the 50/50 split-fold third row even easier, even if it’s still not graceful.

But the six-seat Azami LE is configured differently, given its second row has two captain’s chairs instead of a bench. That said, it operates in a very similar manner, just with power adjustment.

I still had around eight centimetres of legroom and four of legroom behind my 184cm (6'0") driving position, while the large transmission tunnel that’s a foot-space issue in seven-seat versions... isn’t.

One key difference with the very roomy and comfortable Azami LE is it only has four top-tether child-seat anchorage points, while all other grades have five thanks to their extra seat. Either way, four ISOFIX child-set anchorage points are split across the second and third rows.

Alternatively, the third row can be used by adults on shorter journeys, although they won’t have a lot of space to enjoy. Again, I'm 184cm tall and it’s tight back there, with no headroom or legroom on offer, but children will, of course, fare much better.

The CX-9’s boot is still pretty usable with all three rows in action, with 230L of cargo capacity available, but you can stow the two rear seats to get 810L in total.

And if you want maximum cargo capacity, the middle seats can also be folded, but not in the Azami LE, annoyingly.

Either way, the CX-9 doesn’t have a load lip but does have a flat floor, so loading bulkier items is a cinch, while two bag hooks and four tie-down points are on hand for securing loose items if they can’t fit in the double map pockets on the front seat backrests.

There are two cupholders in the third row, another two in the second row’s fold-down armrest (seven-seater versions) or large centre console (Azami LE), and another two in the first row’s larger centre console, while the front and rear door bins can also take bottles – and other knick-knacks.

All grades get USB ports in the first row, while the Touring and above also have them in the second row, and the GT and above also feature them in the third row. It’d be nice if there was no differentiation, though.

The CX-9 has become more expensive, with some grades up a little, while others are up a lot. The range now starts from $45,990, plus on-road costs, and reaches $73,875 (see pricing table below), but there is more standard equipment now.

Either way, two new grades have joined the now-comprehensive CX-9 line-up, bringing the total to six, with the new GT SP slotting in above the mid-range GT but below the previously flagship Azami, which is now bettered by the new Azami LE.

The entry-level Sport and Touring round out the line-up, with each grade coming with front-wheel drive as standard, although all-wheel drive is an expensive $4000 option for all but the Azami that instead asks for a $4435 premium, and the Azami LE which gets it as standard.

Features-wise, the Sport gets dusk-sensing LED headlights, rain-sensing wipers, 18-inch alloy wheels, push-button start, a 7.0-inch central display, satellite navigation, Apple CarPlay and Android Auto support, digital radio, a six-speaker sound system, a head-up display, three-zone climate control and black cloth upholstery.

While the Touring has the same 18-inch alloy wheels, it steps up with keyless entry, a 9.0-inch central display, paddle-shifters (new), power-adjustable front seats with heating, and black leather upholstery.

The GT goes even further with 20-inch alloy wheels, a hands-free power-operated tailgate, a sunroof, the aforementioned 10.25-inch central display (new), a 12-speaker Bose sound system, a wireless smartphone charger (new) and heated outboard middle seats.

As its name suggests, the new GT SP is the sportier version of the GT, adding a unique black finish to its 20-inch alloy wheels and side-mirror caps as well as burgundy leather upholstery and red stitching for just $500 more.

Meanwhile, the Azami has 20-inch alloy wheels with a bright finish (new) as well as adaptive LED headlights, LED daytime running lights, a 7.0-inch multifunction display, a heated steering wheel and 'Pure White' or 'Walnut Brown' quilted Nappa leather upholstery (new).

And finally, the new Azami LE mimics the Azami but replaces its middle bench with two power-adjustable captain’s chairs with heating and cooling plus a dedicated centre console, so six seats in total instead of the usual seven.

Also of note, the CX-9 has a new metallic paintwork option: 'Polymetal Grey', which helps it stand out from the crowd.

For reference, the CX-9’s rivals include the soon-to-be-replaced Toyota Kluger ($44,850 to $68,574) and the recently launched facelifted Hyundai Santa Fe ($43,990 to $61,660) and new-generation Kia Sorento ($45,850 to $63,070).

2021 Mazda CX-9 pricing before on-road costs

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.

All CX-9 grades are powered by a carryover 2.5-litre turbo-petrol four-cylinder engine, which produces 170kW of power at 5000rpm and 420Nm of torque at 2000rpm.

A six-speed torque-converter automatic transmission is standard, and again, you get the option of front- or all-wheel drive for all grades but one, the AWD-only Azami LE.

If you’re after a diesel-powered seven-seater, Mazda also has the similarly sized CX-8 in its line-up, but it still doesn’t offer a hybrid option in any of its SUVs, even though many rivals are moving in that direction, including the aforementioned Kluger, Santa Fe and Sorento.

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.

According to the official combined fuel consumption figures (ADR 81/02), FWD variants of the CX-9 sip 8.4 litres per 100km, which isn’t too bad for a petrol-powered large SUV that weighs just shy of 1900kg. Claimed carbon dioxide (CO2) emissions are 197 grams per km.

And given they weigh a whisker more than two tonnes, AWD versions of the CX-9s drink a slightly higher 9.0L/100km and emit 211g/km.

We covered 188km in the Azami AWD and Azami LE AWD at the CX-9’s launch and recorded 11.5L/100km after primarily driving on country roads and highways.

While that figure is nearly 30 per cent higher than Mazda's claim, it’s not outlandish considering the type of vehicle the CX-9 is. Either way, results will vary.

For reference, AWD variants have a slightly large fuel tank (74L) than their FWD counterparts (72L), but they all take more affordable 91RON petrol at minimum.

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.

As far as large SUVs go, the CX-9 is one of the better ones to drive. It’s certainly not confused; it knows what it needs to do and does it well.

The engine is properly punchy down low, serving up plenty of initial torque, so much so that you rarely need to chase its top-end power. In that way, it’s very diesel-like, despite being petrol. Needless to say, acceleration is surprisingly brisk. Not bad, then!

And the transmission it’s matched to also does its job well. Gear changes are pleasingly smooth, if not quick, while it's receptive to heavy applications of the accelerator, kicking down a ratio or two with little hesitation. Yep, don’t bother with its Sport mode.

The CX-9 also rides pretty well thanks to its independent suspension set-up, which consists of MacPherson-strut front and multi-link rear axles with passive dampers. Indeed, the kids aren’t going to be upset when they’re onboard.

Again, we mainly drove on country roads and highways, but it proved to be comfortable, particularly at high speed. And even during those rare, in-town, low-speed moments, it still impressed, on lower-quality roads or not.

And while the CX-9’s electric power steering is well-weighted, some buyers might be left wishing it was a tad lighter, especially when parking, but that’s more about personal preference than anything else.

What is more universal, though, is the system’s lack of feel. Obviously, we’re not dealing with a sports car here, but a little communication through the wheel wouldn’t go astray, particularly on a twisty road.

Speaking of which, the CX-9 handles its mass pretty confidently around a corner. That said, while it is relatively tied down, it still regularly exhibits a fair degree of body roll to remind you that you’re dealing with a large SUV.

ANCAP awarded the CX-9 its maximum five-star safety rating in 2016, and despite the test occurring nearly five years ago, its results still stand.

Needless to say, the game has moved on, with the Santa Fe and Sorento recently resetting the standard, while the Kluger is soon to follow suit.

The CX-9 does, however, get front and side airbags as well as curtain airbags that cover all three rows, whereas the Santa Fe and Sorento only cover the first and second rows.

All grades of the CX-9 also get front and rear autonomous emergency braking, lane-keep assist, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control with stop and go functionality, traffic sign recognition, high-beam assist and driver attention alert.

A reversing camera and rear parking sensors are also standard in all grades, but the Touring and above add front parking sensors, while the Azami and Azami LE also get surround-view cameras.

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.

As with all Mazda models, the CX-9 comes with a five-year/unlimited-kilometre warranty with five years of roadside assistance, both of which are average when compared to Kia’s market-leading seven-year terms with ‘no strings attached’.

Service intervals are 12 months or 10,000km, with the distance on the shorter side, although capped-price servicing is available for the first five visits, costing $2022 in total at the time of the writing, which is very reasonable.
