BYD Sealion 6 vs Toyota Corolla

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.

The final score for this review makes it look as though the Corolla is a middling effort. The scores for each individual section of the review are well considered and fair. The Corolla does lack the practicality of some of its rivals. A lack of an ANCAP rating isn’t great and the powertrain is just okay. But it remains one of the most fun-to-drive hatchbacks on the market today, even seven years into its life, and I would wholeheartedly recommend the Corolla to anyone looking for a small car. If you can forgive some of the quirks, it is a reliable, adorable, fun and efficient small car favourite. 

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.

It’s been around for a good seven years, but the current-gen Corolla hatch is still a smart design. It has a squat stance and looks as though it has sporty intentions (it doesn’t), and the head and tail-light treatment doesn’t look like anything else in the segment.

The Corolla has adorable proportions and a pert little behind in a sea of increasingly boring small SUVs.

However, in SX trim and in the ‘Sunstone Orange’ body colour of my test car, the Corolla gives off rental car vibes. Which is hardly surprising given lower grade Corollas are a favourite of rental companies.

Inside that vibe continues. This is where the Corolla is really showing its age.

There are various shades of grey throughout the cabin, with a mix of hard and soft plastics. The cloth seat trim is drab, which is a shame because some other brands have managed to make cloth cool again. Not Toyota.

The touchscreen sticks up out the top of the dash like an old iPad and the dash design is old but functional. 

There is nothing inspiring about this interior design. In saying that, of those aforementioned rivals, only the Mazda3 and the new Kia K4 have modern cabins.

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 Corolla is a small car and that is evident inside. You might bump elbows with your front passenger, but I have no problem with the front leg or headroom.

Those cloth seats might be drab but boy they are comfy, and the fronts have loads of side bolstering. 

The steering wheel has typically clear controls and looks and feels nice. 

As a more, shall we say seasoned model in the segment, the Corolla still has buttons on the dash for things like air con, but not too many. That bulbous centre stack and the centre console, however, could be better designed for the space.

As it is, the wireless charging pad is hidden under it at the far end of the console. It’s a bit fiddly to get your phone in and out. This is also where one of the USB-C ports lives.

The other one is in the central storage bin which is quite small, but also houses a 12-volt outlet. There are no other places to store things because of the rounded shape of the console, which also features a couple of narrow cupholders.

OurCarsGuide bottle had to be squeezed into the door storage cavity - only narrow, short vessels will fit properly.

That 8.0-inch multimedia screen is very easy to navigate, with logical menus and icons. However, it’s almost too basic, which is not helped by the all-white background. It could be a more engaging set-up but it’s also very hard to fault the functionality. Our Apple CarPlay maintained its connection the whole time with the car, too.

Space is quite tight in the rear, although I have enough headroom for my 184cm frame. Legroom is just okay behind my driving position. There’s more space in the back of a Hyundai i30. It’s also dark because of smallish rear windows and thick C-pillars. 

The rear seat backrest is quite upright, but, like the front seats, well cushioned.

Amenities are just average back there - there’s a weird cupholder high on the door, only a passenger side map pocket, no rear air vents and no USB ports, although you could easily use the one housed in the front central bin. There’s a rear fold-down armrest with two cupholders.

The rear seats split and fold 60/40 and they fold flat making for a better loading space.

The good news is the SX (and the base Ascent Sport) come standard with a temporary spare wheel, which is great news for a hybrid model. The bad news is, that reduces boot space to a paltry 217 litres. 

That’s off the pace of all of its key hatchback rivals, including the Mazda3 which has its own cargo concerns at 295L, and the Hyundai i30 with 395L.

The Corolla ZR hatch has more space at 333L but you only get a tyre repair kit instead of a temporary spare. 

If you’re dead set on a Corolla but need more cargo space, consider the smart looking sedan that has 470 litres.

Toyota dropped all exclusively internal combustion engine versions of passenger car models and car-based SUVs last year so the Corolla is now hybrid-only.

The grade we tested is the SX five-door hatchback which is priced from $35,260, before on-road costs. Interestingly, the sedan version, which has a much bigger boot, is $340 cheaper.

The SX sits in the middle of the Corolla range with the Ascent Sport the most affordable (from $32,110) and the ZR the priciest before you get to the fire-breathing GR Corolla hot hatch.

Direct rivals at this approximate price point include the Hyundai i30 N Line ($36,000 BOC), Mazda3 G20 Touring ($37,110), Subaru Impreza 2.0R ($35,490) and the Kia K4 Sport ($35,190), although that is sedan only for now.

You get 16-inch alloy wheels, cloth bucket seats, a synthetic leather steering wheel, auto-dimming rear view mirror, rain-sensing wipers, rear privacy glass, keyless entry and start, dual-zone climate control, USB-C ports, a wireless device charging pad, six-speaker audio, an 8.0-inch colour multimedia display with sat-nav, digital radio, Bluetooth, voice assistant and wireless Apple CarPlay and Android Auto. 

The standard features list could be described as adequate without being overly generous for the price. A head-up display (standard in the ZR) would be nice.

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.

Since Toyota dropped the petrol engine from the Corolla range, it’s a hybrid-only affair.

The powerplant is a 1.8-litre naturally aspirated petrol engine paired with Toyota’s fifth-generation hybrid system that incorporates a lithium-ion battery, which is lighter yet more powerful since the 2022 update.

The Corolla drives the front wheels exclusively via a continuously variable transmission (CVT).

It’s not the punchiest engine and could do with more poke, but Toyota does do hybrids well. 

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.

According to Toyota the official fuel-use figure for the Corolla hybrid hatch is 4.0-litres per 100 kilometres and CO2 emissions sit at 90g/km.

While the trip computer said 4.8L/100km at the end of our week, my own fuel consumption calculation came to 5.8L.

You will only need 91 RON 'standard' petrol to fill up the Corolla.

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. 

Most generations of Corollas have been solid, dependable and occasionally, even fun to drive. 

My first car was a Holden Nova GS hatchback, which was a rebadged version of the seventh-generation Corolla. I loved that car. It was zippy, fun and super economical.

The same principles generally apply to the current-gen Corolla. Thankfully, Toyota’s former CEO, Akio Toyoda, insisted all models from the Camry to the Kluger needed to be injected with more fun. And he succeeded with the Corolla. So much so that they've spun off a wild GR performance hot hatch version.

The Corolla sits low to the ground and it just feels much more connected to the road than a small SUV can. Even in mid-range SX guise, the Corolla can hug a corner and there is ample grip to ensure a fun drive on your favourite winding road.

Sure, the hybrid powertrain might not set your heart racing, but it is quick enough from a standing start and it lacks the lag of some of its turbocharged contemporaries. There’s also plenty of poke on tap for a small car when overtaking.

Even though it has a sporting edge to how it handles, the Corolla SX has been tuned for comfort first and foremost and this is another area it excels. The damper set-up ensures the Corolla soaks up speed bumps, nasty potholes and whatever else our shoddy roads can throw at it. At no point in my seven days with the Corolla did I complain about a harsh bump or thud.

Steering has a mechanical feel but it is still sharp, adding to the ‘chuckable’ vibe of this hatchback.

The powertrain can be noisy when pushed and combined with a CVT auto it’s the nicest sounding engine out there. Also, the transition from electric to petrol power isn’t particularly smooth. Other carmaker’s hybrid offerings - like Honda for example - are close to seamless. 

Some road noise gets into the cabin but it’s no deal breaker.

The Corolla is currently unrated by crash safety watchdog ANCAP. It did achieve a maximum five-star rating back in 2018 but that expired at the end of last year.

Safety features are largely standard across all grades and the SX comes with auto emergency braking (AEB) with pedestrian and daytime cyclist detection, lane departure alert with steering assist, speed sign recognition, 'Lane Trace Assist', adaptive cruise control, a blind spot monitor with safe exit assist, a rear cross-traffic alert, reversing camera and front and rear parking sensors and a rear occupant alert.

It doesn’t have a driver attention alert, and it’s all the better for it.

The lane keeping aid is well calibrated and subtle in its interventions, but the adaptive cruise let the speed creep several kilometres over the set speed on several occasions. 

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.

The Corolla is covered by Toyota’s five-year/unlimited kilometre warranty, which, given Kia, MG, GWM, Jaecoo and more have longer terms (not to mention Nissan and Mitsubishi’s conditional 10-year terms) is now officially trailing its competitors.

However, the capped-price servicing plan of up to five years costs just $250 for each service, which is incredibly competitive. The service schedule is every 12 months or 15,000km, whichever occurs first.
