BYD Sealion 7 vs Mazda CX-9

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 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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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.

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.

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.
