Mazda CX-5 vs BYD Sealion 5

What's the difference?

The Mazda CX-5 Akera G35 offers small families a great host of premium features, as well as solid power and handling – all in an attractive package. But the emphasis here is on ‘small’ families because it’s on the compact side for a mid-sized SUV and its rivals offer more back seat space.

Its ongoing costs are reasonable and I enjoy driving it, so it gets a 7.6/10 from me.

My son calls out the back seat as a bit squishy but he otherwise likes it. He gives it a 7.0/10

While the BYD Sealion 5 lacks the polish of some more established plug-in hybrids, it has a seriously compelling price advantage over some competitors. It makes a base-model Mitsubishi Eclipse Cross PHEV feel positively outdated and it’s $13,800 cheaper.

BYD's lack of ANCAP rating for the Sealion 5 and the uncertainty around it still being a new brand are downsides, even if BYD is quickly moving past the latter. But being the most affordable PHEV available while having this much showroom appeal is bound to work in the Sealion 5’s favour, just don’t expect a dynamic masterpiece once you’re out on the road.

The Mazda CX-5 hasn’t seen much change to the exterior other than a more horizontally-styled grille. It’s a medium SUV with a handsome kerb-side presence thanks to its full-suite of LED lights and 19-inch alloy wheels. It’s an inoffensive design that should appeal to a wide audience.

The interior looks premium with the brown Nappa leather upholstery and black leather trims. The plethora of soft-touchpoints throughout reinforces that the Akera is the top model.

There's one thing I really like about Mazda and that's how it manages to balance the traditional with the new. The cabin is a seamless blend of the two elements.

The instrument panel features a 7.0-inch digital display but still has analogue dials. There's a 10.25-inch multimedia system on the dash but still a bunch of control buttons and dials to press. The gear shifter is coupled with an electric brake, the sunroof is coupled with a manual blind. You get it.

This duology between high-end tech and traditional elements makes the interior feel up to date but very accessible.

The BYD Sealion 5, from the outside, is inoffensive but also uninspiring. That’s likely not such a bad thing for a mid-size SUV – it’s rare you’re hearing someone talk about how beautiful the Mazda CX-5 or Toyota RAV4 is. 

Its quartet of colour palette options comes in on the safe side, too. Aurora White is standard, Atlantis Grey, Harbour Grey and Cosmos Black are cost-options.

Our test car is Atlantis Grey, which is interestingly quite blue. 

The relatively upright shape is a slight departure from the more ‘aquatic’ silhouettes of BYD’s line-up, but the front grille and light layout are decidedly in step with the brand’s oceanic design language. There’s a bit going on, you could say.

The slimline tail-lights are the rear, especially from a three-quarter angle to the side, look attractive and help break up the rear without looking messy.

The Sealion 5’s design is overall net-good, but it’s inside where the mid-sizer feels like you’re getting plenty for your dollar.

The seats, despite the leather fakery, feel like decent material, and the layout uses buttons and physical controls cleverly without feeling outdated.

Despite sitting in the medium-SUV segment, the CX-5 is on the compact side for cabin space and front passengers benefit the most in terms of leg- and headroom.

Back rowers get a decent amount of headroom but legroom is squishy and my legs press into the back of the drivers seat when its in my driving position, and I'm only 168cm tall!

My seven-year old complained about his space and asked Dad to slide forward for more room, which is something to consider if you have gangly teenagers.

The seat comfort sits on the firmer side for both rows and the electric front seats are narrower and shorter than I like for long journeys but for the A to B trips, they’re comfy enough.

Only the driver’s seat gets powered lumbar support but they both have heat and ventilation functions.

Individual storage is average for this class with a smallish glove box and middle console that has a removable shelf. A deep utility tray, which houses the wireless charging pad and a 12-volt port, sits in front of the gearshift and there are two cupholders in the centre console.

Each door has a shallow storage bin and the front doors also get a skinny drink bottle holder.

For individual storage in the rear, you get map pockets on the rear of the front seats and two cupholders in a fold-down armrest.

The armrest also houses two USB-A ports and the heat function buttons for the outboard seats and it's because of this positioning and the narrower width of the seat, that the back row feels more suited to two, rather than three passengers.

The technology on the whole is easy enough to use but the rotary dial operation of the multimedia system is a bit annoying to access while on the go.

The wireless Apple CarPlay and Android Auto is a great feature and means one less cable to worry about but the built-in satellite navigation with 10-year map updates is a highlight. The head-up display pulls through the nav directions, too, which is always handy.

You also get two USB-C ports and another 12-volt outlet up front, so everyone should be sorted for charging.

The boot features a powered tailgate which is a handy family feature and a temporary spare tyre is located underneath the level floor.

You get 438L of storage capacity with the second row seat upright, which is plenty for my errands and grocery shop. That jumps up to 1340L (VDA) when the rear seats are folded. 

The cargo cover attaches to the lid, meaning it stays out of the way when you're loading stuff into the boot.

To actually interact with the interior is, at times, another story. BYD’s tech interface is generally easy to manage, but could be simpler when it comes to navigating menus for the sake of driver distraction.

While larger text and buttons would be welcome, the multimedia system is easy to use when parked, and the functionality is impressive for the price point.

Winning more points for the Sealion 5, though, are the physical controls – buttons and the traditional gear selector – which make the cockpit much more intuitive while on the move.

Ergonomically, though, the adjustment between the steering wheel and driver’s seat could do with some work, as I found it difficult to find a truly comfortable driving position. This is coming from someone 178cm tall, a very normal height in Australia.

Better adjustability on the steering column would be helpful, as it’s something I’m not sure I’d ever get totally used to.

Visibility and physical space inside the Sealion 5 is impressive, though. The car is 4738mm long, 1869mm wide and 1710mm tall, and the roof and window lines don’t swoop too aggressively towards the rear.

There are low window shoulders even into the rear, so light isn’t at a premium, though under-leg support could be better on the pew.

It’s otherwise un-cramped. The 2712mm wheelbase means decent legroom for second-row folk, plus behind the 60/40 split-fold seats there’s 463 litres of space for luggage. That becomes 1410L with the seats folded.

There’s unfortunately no spare tyre, just a tyre repair kit.

The BYD Sealion 5 Essential kicks off from $33,990 before on-road costs, four big ones less than the Premium ($37,990). We’re focusing on the Essential today, but don’t think that means a shallow list of features.

As you’d expect from BYD if you’ve been paying attention to the Chinese brand in its emergent years, the Sealion 5 comes with more than $34K would normally get you – a 10.1-inch central multimedia touchscreen, an 8.8-inch driver display, synthetic leather upholstery, dual-zone climate, a six-speaker sound system, wireless Android Auto and Apple CarPlay, USB-A and -C ports front and rear, digital radio and keyless entry.

On the outside, LED headlights and tail-lights are the same for both variants.

Both also have 18-inch wheels, not unwelcome for the benefits of on-road comfort.

Consider that the most popular SUV in the country, the Toyota RAV4, costs at least $45,990 without the benefit of a plug-in drivetrain (yet) and comes with, on paper, a more sparse list of features.

The closest PHEV competitors are still more pricey, including the Geely Starray ($37,490) and Chery Tiggo 7 ($39,990), and arguably lack the brand power BYD has come to enjoy.

The Akera is an all-wheel drive with a six-speed auto transmission and our test model has the 2.5-litre four-cylinder turbo-petrol engine that produces a maximum power output of 170kW and 420Nm of torque. The turbo ensures it never feels sluggish, even when you’re hitting hills.

The Sealion 5’s front wheels are driven by a combined maximum of 156kW thanks to a 1.5-litre four-cylinder petrol engine (145kW/300Nm) and a permanent magnet synchronous motor (72kW/122Nm).

BYD claims a 0-100km/h sprint of 7.7 seconds for the Sealion 5 Essential, four tenths faster than the Premium despite only a 61kg difference in kerb weight.

The compromise for getting extra power from the turbo is fuel efficiency takes a hit.

The official combined fuel cycle figure is 8.2L/100km but my real-world usage came out at 10L/100km. That’s after mostly open-road driving this week, too, so it’s a bit thirstier than I was expecting.

Based on the combined cycle number and the 58L fuel tank, expect a driving range of around 784km – which is still great for the odd road trip.

With a charged 12.9kWh lithium iron phosphate (LFP) battery and a full 52-litre (95 RON minimum) fuel tank, BYD reckons the Sealion 5 Essential can cover 1001km under NEDC testing, which is optimistic. It claims 71km can be done on EV power alone.

Not only due to the lenient nature of NEDC testing (WLTP is more common and usually results in lower ranges), but the reality is that once the battery is flat, the engine is doing a lot more work.

Charging is slow, limited to 3.3kW (AC only), which should take between 4 and 5 hours to charge from the lower end of the gauge for the battery size. Given most PHEV owners will do this overnight at home, that’s certainly not the end of the world.

Claimed consumption figures are 1.2L/100km with more than 25 per cent battery charge, or 4.5L/100km when it dips below that.

Realistically you could do sub-50km trips and use no fuel, or never plug your Sealion 5 in and see fuel consumption soar. In any case, anything close to 1001km in a single run is extremely unlikely.

The Akera turbo-petrol delivers a decent well of power to dip into and it feels peppy in most situations. Even when you’re overtaking or getting up to speed you don’t feel like you’re nearing the bottom of the power barrel.  

Steering is responsive and the car is agile when you tackle narrow car parks or streets. However, you still get some roll in corners which my passengers felt more than I did.

The cabin is quiet, even at higher speeds and the suspension is firm enough that you feel the bumps but you’re not jostled about. The ride comfort is still good.

I’ve said it before but I love parking medium SUVs because their size is so forgiving in a car park! The Akera is no different and it’s especially easy thanks to the ultra-clear 360-degree view camera system. You also get front and rear parking sensors to help out when needed. 

You might expect a car at this price, regardless of its drivetrain, to be underwhelming from behind the wheel.

That, then, makes it even more pleasantly surprising that the BYD Sealion 5 is actually rather competent. Not massively exciting or dynamic, but certainly not a disappointment.

The Sealion 5 is, save for a couple of arguably minor annoyances, quite easy to get used to and drive.

Firstly, when making proper use of its electric power, the drivetrain provides enough shove for its intended use. It’s not overly powerful, but you won’t have trouble overtaking. It’s the same with most of the inputs, the steering is light but not completely numb – again about right for how the Sealion 5 will be driven.

Perhaps its biggest departure from expectations based on other cars from China is its suspension is on the stiffer side of things, but again it’s not unruly or too rugged. In fact, it does provide a better sense of control than many of its compatriots.

Again, the biggest issue with the Sealion 5 day-to-day is its driving position, the steering column adjustment isn’t up to scratch and there’s not really a perfectly comfortable seating position (I’m a very standard 178cm).

On long trips, you might also find the engine gets quite noisy once the battery power is gone as it works hard to pull the mid-size SUV along under acceleration.

Its driver-assist systems are, you might be pleased to hear, on the calmer side of things – BYD is getting better at calibrating its safety features and I didn’t find myself rushing to switch it all off as quickly as usual.

It can still be a bit too persistent in its lane-keeping, but it’s a big improvement on the way things were.

There’s no ANCAP rating for the Sealion 5, but the list of safety kit isn’t lacking on paper.

BYD lists seven airbags ,including full-length side-curtain bags and an important centre airbag, plus there’s a whole suite of tech that’s, as noted, better behaved than past driver-assist systems from BYD.

The Essential only misses out on a surround-view parking camera and front parking sensors, both arguably important safety features for parents, but the rest of the list is the same as the Premium including adaptive cruise control, lane-keep and lane departure assist, traffic sign recognition, blind-spot monitoring, rear cross-traffic alert with rear AEB (as well as front AEB, of course) and tyre pressure monitoring.

The CX-5 comes with a five-year/unlimited km warranty, which is average cover for the class but some of its rivals offer longer terms.

There is a five-year, or up to 75,000km capped-price servicing program and services average $423 per workshop visit, which is competitive.

Servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.

BYD has a six-year/150,000km warranty, which is probably more than you’d need in terms of distance but is behind many competitor brands’ timelines – seven to 10 years is becoming the norm, even if it’s conditional.

An eight-year/160,000km warranty covers the battery, which is about par for the industry.

Servicing for the first five proper services ranges from between $285 and $930, plus there's a free check-up six months into ownership and a total cost over the span of $2355 – an average of $471 per service.

BYD has just over 100 dealerships in Australia, so finding one for servicing shouldn’t be too challenging.
