BYD Sealion 6 vs Mazda 2

What's the difference?

So, should Toyota, Tesla, Hyundai and others be worried about the arrival of the Sealion 6 and BYD’s new DMi powertrains? Yes, but not because it represents any major breakthrough in technology or dynamic prowess. 

Instead, the strength of the Sealion 6 is how average it is. It may not be the obvious class-leader in any particular area, but it does a good job in almost every measurable aspect and doesn’t possess any major flaws.

Yes, there are still questions about the long-term dependability of BYDs but that’s a risk any new owner will need to accept. But the very sharp pricing should tempt plenty of buyers to take that chance and continue BYD’s steady upwards trajectory in the Australian market.

While Mazda's insistence that the Mazda2 is a 'first-car' could be very limited by the incomes of most teenagers or early-20s city-dwellers, the starting price being close enough to $20,000 for a dynamically enjoyable and convenient small car isn't to be scoffed at.

The new styling of the Mazda2 is well executed, and as an alternative to small SUVs (which continue to become more popular) it's a sensible option, especially considering its efficiency and ease of use.

The lower specifications in the range are probably the best in terms of value, as even the features on the higher grades aren't groundbreaking, and the Pure SP definitely exudes the most style cred.

This is one area where BYD has a mixed record. Not to be unkind or create an international incident, but the Chinese car industry has a history of not being totally original with all of its automotive designs.

However, things are improving and the Sealion 6 is a good example of the Chinese industry learning to develop its own style. While there are some subtle hints from European models, overall it’s a smart-looking mid-size SUV with some character to it - rather than being a bland imitation of something else.

One area where the Sealion is a cut above its competition is its size, being longer than and wider than the RAV4, Mitsubishi Outlander and Nissan X-Trail.

Aside from the Pure SP, the Mazda2's styling changes are subtle. Mazda's design team aimed to move the model's looks slightly away from the previous ‘premium' chrome-adorned look to a sportier and more ‘aggressive' style.

A redesigned front bumper and mesh grille, with the rear's nip and tuck being more subtle, don't need to do much to keep the hatchback looking fresh. Despite being almost a decade old, the Mazda2 looks, to some extent, like it could be a new generation.

The Pure SP in particular is a highlight, with the blocked grille evoking some ‘electrification' vibes, while the coloured-accent treatment at the front and rear of most variants is a welcome addition for something different.

The range of differing wheels is also a plus point for the Mazda2 range, with each model having its own distinct characteristics.

Inside, the Pure SP also gets a stand-out panel across the dash in a lighter colour like mint, while others get different seat trims and colour accents in places like the vent surrounds.

New colours for the range are 'Aero Grey Metallic' and 'Air Stream Blue Metallic'.

That external size translates to a roomy cabin, which also has some flair to the design but thankfully a bit more restrained than the smaller Atto 3 - which is a bit over-the-top in this reviewer’s opinion. 

The element that sticks out immediately is the large central touchscreen which, like other models in the range, can rotate either vertical or horizontal, depending on your preference.

I don’t understand the point of this, because when rotated vertically it impacts your forward vision and can interfere with the air conditioning vents; and I can’t even see it with my polarised sunglasses.

It simply makes more sense horizontally, but I guess all carmakers are looking for catchy gimmicks these days. But while it may seem like a cool party trick it remains somewhat confusing to me, like one more thing to go wrong. But maybe I’m just getting old and grumpy.

What I do like and think is a great idea is double smartphone charging pads in the centre console. And overall the design of the cabin feels well thought out and has plenty of useful storage areas.

The seats are fine, a little flat and the fixed headrests are irritating, but overall they’re soft and supportive enough.

The key in the second row seating is the amount of space, with the extra length of the Sealion 6 compared to its rivals showing up with more knee room in the back for families with growing teenagers or those who need to carry their adult friends.

There’s also a pair of USB ports in the back too, so everyone can keep their electronics charged.

The boot is a good size, measuring 425 litres on paper, and has a nice long and wide floor. But some of that space is thanks to the lack of a spare - so that counts against it in my book.

The Mazda2's interior is mostly unchanged through the facelift, with the car's overall dimensions unchanged and not affecting space for its occupants.

Up front, the two seats are comfortable for adults and arm, shoulder, and head room is ample.

Storage space for drinks, phones, or small bags and wallets is sufficient, though not quite road-trip-worthy.

In the rear seats, adults will find enough space to be comfortable for short trips but might get a little restless after a while.

Headroom when sitting upright is tight for anyone around 182cm (six-feet) tall, and a lack of armrest and little storage save for the doors means loose items will be joining occupants on the seat or sitting on the floor.

The Mazda2 has a claimed 250 litres of luggage space in the boot, which is fine for a small hatchback, but short of rivals like the Toyota Yaris' 270L.

Mazda has managed to keep pricing for its entry model relatively low for the segment. In fact, the base Pure in manual form starts from $22,410, before on-roads, and the auto is only $2000 more.

That means at a time when the Toyota Yaris is starting to look more expensive than its historic ‘cheap and cheerful' image allows, Mazda is pushing the Mazda2 to be slightly more premium while keeping its price competitive.

Standard features for the range, which start in the Pure variant, include a 7.0-inch touchscreen with Apple CarPlay and Android Auto capability, plus auto headlights and windscreen wipers.

The Pure SP, which starts at $25,210, gains a different styling kit that adds a body-coloured front panel to the grille, plus a carbon-look roof in vinyl. It also gains the ‘shark-fin' roof aerial.

The Evolve, which starts from $25,910, gains LED DRLs, with the mesh grille replacing the SP's block colour panel.

Its upholstery gets red stitching, plus it's also got a couple more tech additions with Mazda's active head-up driver display, traffic sign recognition and satellite navigation.

Finally, there's the top-spec GT, from $27,610, which gains unique aero-inspired 16-inch alloy wheels, and a set of black leather-upholstered seats with synthetic suede and red trim.

A sedan is available in Pure or GT specification at the same prices and with the same features as the hatch, though you can't get a Pure sedan in manual - that's available in the hatch only.

While BYD has made its name in Australia as an all-electric brand it has always referred to itself as a 'new energy' company, and the Sealion 6 (and upcoming Shark ute) are why.

That’s because these feature BYD’s new 'Dual-Mode Intelligence' (DMi) powetrain - a hybrid system to you and me.

As mentioned above, the biggest difference between the Dynamic and Premium models is the powertrain, with two reasonably different systems.

The Dynamic is powered by a 78kW/135Nm 1.5-litre four-cylinder petrol engine, paired with a 145kW/300Nm electric motor - making for a combined system output of 160kW/300Nm. Notably, this powertrain only drives the front wheels.

In contrast, the Premium has an all-wheel drive set-up, combining a turbocharged version of the petrol engine (good for 96kW/220Nm) with a pair of electric motors, one on the front axle and one on the rear to produce a combined output of 238kW and 550Nm.

Both models get the same 18.3kWh ‘Blade’ battery, which is BYD’s proprietary technology underpinning all of its models and is attracting attention from other brands.

For reference, the Outlander PHEV has a 20kWh battery, Nissan’s X-Trail e-Power has a 2.1kWh battery, while the more conventional RAV4 Hybrid has just a 6.5Ah battery.

Mazda's ‘SkyActiv-G' 1.5 litre four-cylinder petrol engine is the unit used for six-speed manual and automatic models, but outputs vary slightly.

Manual cars produce 82kW and 144Nm, while autos deliver a slightly lower 81kW and 142Nm, both driving the front wheels only.

It's pretty much the same engine you used to find in an entry-grade MX-5, just with less power.

There are multiple modes to drive it in, including electric only, with the Dynamic able to go up to 92km on a single charge, while the Premium manages a claimed 81km.

However, it's important to note these are the NEDC standards and not the more real-world like WLTP,  so you may not achieve those in practice.

The claimed fuel consumption is an impressive 1.1L/100km for the Dynamic and 1.4L/100km for the Premium although again achieving those in the real world will take some effort.

With a 60-litre fuel tank BYD claims the Dynamic has a driving range of just over 1000km, while the Premium can manage around 960km.

It's also worth noting the Sealion 6 comes equipped with vehicle-to-load charging which means you can draw power from the batteries to run small electronic devices if you need to.

It’s a bonus feature that may or may not be of use, but is one of those things that may come in handy one day to get you through a camping trip or a BBQ at the park.

Improved fuel efficiency and lower CO2 emissions come thanks to the automatic's slight drop in power and torque.

Mazda claims a 5.0L/100 km rating for the automatic Mazda2, which is down by 0.3L/100km over the previous version, but the manual's unchanged engine tune burns through the petrol at 5.4L/100km.

Filling the 44-litre tank with at least 91RON or even E10 is fine, and with its auto variant's efficiency rating means the Mazda2 technically has a theoretical range of 880km.

Comparatively the Mazda2 scores well here, the more expensive Toyota Yaris comes with a 4.8L/100km consumption claim with its CVT auto. A Suzuki Swift, with a smaller 1.2-litre engine, also has a 4.8L/100km rating.

We drove the Sealion 6 Dynamic and despite having the less powerful powertrain it feels good on the road. The DMi system offers good performance, with quiet acceleration off the mark and a good integration between the petrol engine and electric motors. We haven’t driven the Premium yet, so we can’t make any comment on how different it feels.

It’s hard to make a definitive call on the Sealion PHEV powertrain because, like every plug-in hybrid, its greatest strength relies on how the owner operates it.

If you don’t charge the battery every day or so, you’ll just end up lugging around a battery and electric motor for little benefit. However, if you do keep the battery topped up, you can do most of your urban commuting without needing to turn the petrol engine on, which should result in some very low fuel consumption figures.

The company clearly knows this, which is why BYD Australia is offering a complimentary home charger to the first 3000 customers who order a Sealion 6.

Not only will that encourage sales but it will also help owners become evangelists for PHEVs in the future, because they’ll have the best possible experience.

So, a large part of its strength or weakness rests on the owner’s behaviour and that’s something we can’t assess.

As for the rest of the driving experience, the ride comfort is fine. It can’t match the class-leaders for compliance or dynamics, but the Sealion feels pleasant to drive around the urban environment and on the freeway at speed.

Biggest criticism is the steering is very, very light. While that makes parking easier, it feels so light you get very little feedback from the front wheels so it can feel vague at times.

Overall the driving experience is best described as fine. It doesn’t have any major vices but neither does it set any new benchmarks. 

Our drive loop for the Mazda2's launch included a mix of urban, highway, and rural driving, with varying road quality and conditions.

Fortunately for the little hatchback, it handled everything well or at least at a passing mark, with only a couple of small shortcomings that are common in the segment.

The Mazda2 is a joy to drive in most circumstances, with a lively but confidence-inspiring chassis and controls that give a connected feel to the road.

At low speeds, the Mazda2's relatively low power isn't noticeable, with the gearbox getting things moving at a reasonable pace and the engine is responsive enough with the traditional gearbox helping it along.

It's worth noting that for ultimate control over the drivetrain, Mazda still offers a six-speed manual transmission in the entry-grade Pure, and it's a gem.

Smooth, sporty shifts and well thought out gear ratios mean the manual is easy to handle even in traffic, and the clutch has a forgiving bite point. The 'i-Stop' stop/start system works with the three-pedal car, too, as does cruise control.

In terms of handling and comfort, the Mazda2 is a little shaken by large bumps, though some of the rough surfaces on our test loop were particularly brutal.

Similarly, when pushed hard to conquer steep hills the 1.5-litre engine becomes a little harsh.

On twisty sections the Mazda2 (especially in manual form) provides ample fun while remaining predictable in its steering and chassis feedback, rather than feeling loose.

The updated Mazda2 is equipped with the brand's suite of 'i-Activsense' safety tech, which includes 'Smart City Brake Support' for operating forward and reverse, blind-spot monitoring and rear cross-traffic alert.

The Evolve and GT model grades are fitted with traffic sign recognition.

The GT model grade comes fitted with front parking sensors and a set of surround-view parking cameras.

The Mazda2 also features six SRS airbags to cover the driver and front passenger, side airbags, and curtain airbags front and rear. It also has ISOFIX anchor points and top tethers for child seats in the rear.

Mazda isn't going to put the Mazda2 up for a new crash test rating by ANCAP, with the brand telling us the new safety additions bring the car's safety up to date, though its original rating from 2015 was a maximum five stars.

BYD is a small company but has partnered with mycar service centres to make maintaining your Sealion 6 easier. The Sealion is covered by BYD's six-year/150,000km warranty as well as its 10-year capped price servicing plan.

Service intervals are every 12 months/20,000km and prices range from $265 up to $1184 for the major eight year/160,000km tune up. Over the first five years, in keeping with most of its rivals, you’ll be paying $1648.

As I’ve written in previous BYD reviews, the biggest question mark hanging over the brand is arguably its long-term prospects. Quite simply, the brand is still too new to know how well it will perform on the used car market.

We also can’t tell you how it will hold up from a reliability point-of-view. We’re not suggesting there’s any doubt over its quality, but each car brand must prove itself reliable and dependable over time, and BYD hasn’t had that time yet.

Mazda offers a five-year/unlimited-kilometre warranty across the range, under which the Mazda2 will be covered. That's on par for the market, although some rivals, like the MG3, come with a seven-year term.

Scheduled servicing costs for the first seven workshop visits range from $334 to $587, and are undertaken every 12 months or 15,000km (whichever comes first).
