BYD Sealion 6 vs Mazda BT-50

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.

Key to the success of the BT-50 XS will be acceptance by fleet buyers. The vehicle, however, seems to be pretty well considered as far as that goes, although as with any stripped-down model, there are features that will be missed. Things like the manual air-conditioning probably won’t make much difference, but the lack of a tyre pressure monitoring system is a bigger issue for a working vehicle. Performance from the smaller engine is still well within acceptable parameters, but we reckon any buyer considering using much of the 3500kg touring capacity would be better off with the 3.0-litre engine offered in the rest of the BT-50 range.

The Mazda is not the best riding of its ilk, and there are competitors with bigger cabins, although, notably, at this point on the pricing ladder, these are often from China rather than Thailand where the Mazda is built. Ultimately it will come down to whether the smaller engine and reduced performance is an issue and also whether the money saved over the bigger-engined BT-50 is enough to justify that and the loss of some creature comforts. But since fleet managers are notoriously hard-nosed about this stuff, there’s a good chance to BT-50 XS will find a market.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

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.

Targeting tradies and fleet customers has meant Mazda has embraced the concept of factory accessories. Right now, there are options for tougher front bumpers, bull-bars, snorkels, drop-side trays, an awning, wheel-arch flares (for bigger, aftermarket wheel and tyre packages) driving lights, roof racks, canopies, tub-drawer systems and even a dual battery set-up. All these factory options carry the full Mazda warranty.

But Mazda has gone even further with accessory packs aimed directly at different fleet markets. For instance, there’s the Mine-Spec Pack which incorporates a park-brake alarm, high-mounted brake lights, a reversing buzzer, work-lights, LED rear lighting and pre-wired switches for auxiliary and beacon lighting.

Externally, Mazda's design brief for the BT-50 has clearly been to not frighten the horses. But it's better than that, because it has actually emerged as one of the better looking utes out there. In XS trim, even the steel wheels add a no-nonsense flavour to the overall effect. And where some of the competition appear to be trying very hard to ape the full-sized US-made pick-ups, the Mazda is its own thing.

Inside, the smaller info screens and simple layout in basic black tell the budget story. At the same time, there's a lot to like in terms of the clear, simple analogue gauges and the no-fuss controls including the conventional T-bar, park-brake and ignition key. There's a look and feel that also suggests this is a ute that should be able to take a few knocks in the course of earning a living.

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.

With a choice of cab-chassis of pick-up tub, not to mention the option of a single or dual-cab body in cab-chassis form, the XS allows for a fair bit of creativity in how it’s configured. The cab-chassis, for instance, will accept a conventional drop-side alloy tray or any number of service body configurations right up to camper bodies.

The stock tub on the pick-up version gets a drop-in liner but there’s no power outlet or light that some of the competition offer. The tie-down points are also a bit disappointing with two lower points in the rear of the tub and a pair of higher points in the front. Experience tells us that high-mounted tie-down points are vastly less practical than anchor points mounted close to the cargo floor.

The move to the larger engine has, however, increased the Mazda’s towing ability. From the previous version’s 3000kg towing limit, the new 2.2 can now legally tow 3500kg (with a braked trailer and approved tow-hitch). Payloads vary according to specification, but range from about 1000kg right up to 1379kg for the XS singe-cab-chassis.

The factory-option drop-side tray carries it’s load up high, but offers a flat floor with no wheel-arch intrusions. The standard tub is not as large in any direction, but does have a damped tailgate for safety (you can’t drop it) and convenience (the gas struts help raise it).

In the cabin, you get USB charging ports (two in the front, one in the rear seat) and there are central air-vents for the rear seat of dual-cab models. The dual-cab also has an under-seat storage area, two gloveboxes and a 60/40 split fold rear bench. The doors feature bottle holders and there’s a flip-down glasses compartment in the roof lining.

While the front seats are comfy enough for bigger drivers, the rear seat also goes against dual-cab tradition a little by having plenty of room in every direction, as well as a rational seat-back angle.

While the XS remains the entry-level BT-50 variant, you once again have the choice of two or four-wheel drive, with price-tags to match. So, starting at the start, the 4x2 XS single-cab cab-chassis now kicks off at $37,900 before on-road costs with the dual-cab pick-up (styleside) 4x2 variant at $46,710.

Move up to all-wheel drive and there’s no single-cab option. Instead, things start with the dual-cab cab-chassis 4x4 at $53,120 and the dual-cab pick-up at $54,720.

Aside from the bigger engine and stronger performance, you now get an eight-speed transmission and there’s fuel-saving stop-start tech that was once only available on higher-spec BT-50s.

Other additions for the XS include LED headlights, adaptive cruise control, wireless connectivity for both Apple Car Play and Android Auto, a reversing camera and an 8.0-inch touchscreen. There’s also digital radio and hill-descent control.

But the XS’ place at the bottom of the BT-50 ladder is confirmed with the cloth-trimmed interior, vinyl flooring and plain steel wheels for all but the dual-cab pick-up 4X4 variant which gets alloy wheels.

Which is all fine and gives the Mazda something of a pointy stick with which to poke at the incoming competitors (mainly) from China, but where does that place the XS relative to the 3.0-litre BT-50? Well, if you take the XT variant with the 3.0L engine and the same body and driveline layout, the XS comes in at just $2500 less. That’s not a huge saving either as an outright number or in terms of the monthly lease repayments.

Part of that is because Mazda has also hiked prices across the BT-50 range in tandem with announcing the new XS. Which means that spec-for-spec 1.9 versus 2.2-litre XS is now $1500 more than it was. But even if Mazda had held prices on the XS variants, would $4000 be enough of a difference? For reference, the original XS sliced $3000 off the 3.0L price when it was launched back in late 2021.

There are areas where you can see where Mazda has pulled a few dollars out of the vehicle, starting inside with the small centre touchscreen, the truly tiny central dash-cluster screen, and the cloth trim. There’s also a bit of hard plastic in evidence and the air-conditioning lacks the set-and-forget function of climate control systems. The keyless entry and start has gone and the XS is started with an old fashioned ignition key. The XS specification also loses the front and rear parking sensors and the tyre-pressure monitoring system.

You might also imagine the drum rear brakes are another giveaway but, in fact, they’re standard across the whole BT-50 line-up.

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.

The new engine capacity of 2.2 litres is up from the 1.9 of the previous XS version but still well short of the 3.0 litres of the more expensive BT-50 versions. And the specifications are pretty much exactly what you’d expect with the new 2.2 just about splitting the difference between the old 1.9 and the 3.0.

In this case, that equates to 120kW of power and 400Nm of torque, while the 1.9 was good for 110kW and 350Nm, and the 3.0 sports 140kW and 450Nm. So, yep, somewhere right about the middle. And that makes sense given the new 2.2 uses the basic mechanical architecture of the 1.9.

But the switch up to the new engine brings one very important change and that’s the adoption of an eight-speed automatic to replace the six-speed unit fitted to the previous XS and the other BT-50s. That has an obvious potential benefit for drivability, but also for fuel economy.

Mazda has also added stop-start tech to the XS in the name of efficiency. But, as we’ve found many times before, the fuel economy benefits seem restricted to the official test results rather than the real world where this technology serves to annoy many drivers more than anything else.

If you opt or the four-wheel-drive variants, you’ll get a rear diff lock but you miss out on an on-road 4x4 setting. Considering the 2.2-litre’s newfound towing capacity (the full 3500kg of the competition), that lack of a 4x4 Auto setting is a shame, but not an unexpected one at this price-point.

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.

While one of the expected benefits of the 2.2-litre engine compared with the three-litre unit is a reduction in fuel consumption, the new 2.2 engine goes one big step further by actually being more frugal than the 1.9-litre engine it replaces. Well, in terms of the official government test, anyway.

The single cab-chassis model in new 2.2-litre, two-wheel-drive form posted a combined (urban-highway) fuel number of a creditable 6.9 litres per 100km. Compared with the mechanically similar 1.9 single cab-chassis, that’s a saving of 0.1 litres per kilometre, and a corresponding drop in tailpipe carbon emissions of 1 gram per kilometre.

To be honest, this small improvement is probably largely due to the stop-start system now fitted, which many drivers will turn off at the first opportunity. Even so, the new eight-speed transmission must also be playing a part, so let’s call the old and new engines line-ball in the real world.

The rest of the XS line-up scored official figures of 6.3 litres per 100km for the double-cab pick-up 4x2, 7.1 litres for the double cab-chassis 4x4 and 6.6 litres per 100km for the dual-cab pick-up 4x4.

With the BT-50’s standard 76-litre fuel tank, the theoretical range is more than 1000km. In reality, that’s going to be closer to 800km.

The BT-50 engines do not require AdBlue additive to reduce exhaust emissions.

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. 

Striking the right balance between ride comfort and load-lugging capacity has always been the big trick with utes in general. The fact is, there’s probably no ideal setting, especially considering the range of payloads a ute can be expected to carry on any particular day. In the BT-50’s case, Mazda has opted to go for a stiffer suspension tune. That means it can technically tow and haul with the best of them, but it also dictates that ride quality is far from what you’d call plush, even in this market segment.

The ute handles bumps best when the undulations don’t come too hot and fast. But strike a patch of high-frequency lumps and bumps and the suspension, particularly at the rear, starts to pogo about with a corresponding decline in ride control. The steering, too, seems to lack a little feel and is relatively slow-geared (although that has its benefits off-road).

The engine certainly does the job in isolation, but it’s likely to struggle a little with the full three-and-a-half tonnes on the hitch. It’s pretty noisy, too, and definitely sounds like a diesel, unlike some modern diesel designs that are more refined. There’s also a sense that Mazda has ditched some of the sound deadening of other BT-50 models, as the engine is certainly heard and felt. The optional snorkel moves the induction noise right into the driver’s window when it’s open, too.

But the new eight-speed automatic transmission is a beauty. Upshifts are crisp and smooth and even the downshifts as you approach a full stop are measured and calibrated to never intrude. And it’s nice to see a conventional T-bar shifter with no separate park button or non-intuitive movements required.

We didn’t get a chance to try the BT-50’s off-road chops, but past experience tells us that the Mazda will be pretty good. As with many four-wheel-drive utes, the limiting factor will be the standard tyres fitted at the factory.

While alloy wheels and carpets on the floor might be negotiable on a vehicle like this, a basic level of safety gear is not. So, the XS gets front, knee and side-curtain airbags, as well as givens such as anti-lock brakes and stability control.

But it doesn’t stop there with the BT-50 XS also fitted with the bulk of the current driver aids. Those include blind-spot monitoring, lane keeping assistance, lane-departure warning, rear cross-traffic alert and the reverse camera system. There’s also autonomous emergency braking which can also identify pedestrians and cyclists.

You also get Mazda’s own take on the controversial driver-attention monitor which many ute makers simply haven’t managed to get right in terms of the system’s calibration and how aggressively it acts. The BT-50’s is one of the less intrusive ones.

What’s missing? On a vehicle designed to tow big loads, a tyre pressure monitoring system is a great addition, but not one you’ll get on a BT-50 at this price. We’d also like to see an on-road 4WD setting which would allow the use of all-wheel drive when, say, towing on a bitumen road. More expensive competitors have this, but the Mazda is hardly alone in not offering this tech at this entry-level price.

The XS variant picks up the five-star ANCAP safety rating already awarded to the rest of the BT-50 line-up.

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’s standard five-year/unlimited-kilometre warranty applies to the BT-50 range, and includes the first five years of roadside assistance, too.

Service intervals are every 12 months or 15,000km, whichever comes first. Capped-price servicing is available with the first five years of servicing costing $2188 on 4x2 versions and $2302 for 4x4 variants.

It’s worth mentioning that the BT-50’s new engine is Euro 5 compliant but doesn’t require AdBlue, reducing running costs.
