BYD Sealion 8 vs Toyota Corolla

What's the difference?

There’s quite a bit to like here. There’s plenty of equipment, and lots of choice in price, trim level and mechanical complexity.

The driving dynamics are fine if you’re not looking for anything sporty although the performance offered by the dual-motor variants must be considered excessive, even if it’s pretty exciting the first time.

Perhaps what’s missing from the Sealion 8 experience is anything that stamps the car as something special within its hotly-contested market segment. Which is another way of saying it offers up the same limitations, most notably in the third row accommodation and access.

You only need to drive a one-box people mover and utilise the rearmost seat, to understand that the two-box SUV, while a pretty marketable thing, is compromised once the passenger count exceeds five. Nothing new there, but nothing new in the BYD, either, to change that narrative.

At which point, the front-wheel drive variant emerges as the most pragmatic choice and probably the one that meets all the important family tasks headed its way for the smallest outlay.

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

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. 

BYD has done its best to give the Sealion 8 its own character and vibe. In fact, it’s a pretty smart looking thing - although still very much a two-box wagon concept - and that’s no given when you consider how much some big SUVs can start to look like large blobs of nothing when you look closely.

There’s the usual Darth Vader stuff at the front, but in profile, the diagonal vent across the front door makes a bit of a statement. The 'plaited' motif of the tail-lights might be stretching things a bit, though.

Inside, the modern board-room feel is invoked by the angular lines and high-tech look and feel of the large info-screens. The panoramic sunroof of the Premium grade also helps brighten up an otherwise pretty dark space.

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.

BYD has made sure all three rows of the Sealion 8 are fit for purpose while attempting to make the rearmost row (traditionally the trickiest to get right) less of a downmarket place to be. With that in mind, both rear rows get air vents and climate-control adjustment for that part of the car. There's also a pair of USB-C charge ports in the second row and a single USB-C and USB-A port in the third row. The third row also has cupholders bult into the wheel arch on each side.

With the third row in place, there’s a decent amount of luggage space (270 litres) largely thanks to the Sealion’s five-metre overall length. There’s no spare tyre, but a puncture repair kit lives under the floor (as does the removable cargo blind) and the rearmost luggage space also incorporates a 12-volt socket and luggage hooks.

A pair of pull-tabs drop the headrests and then the entire split third row in a single movement, at which point you suddenly have a five-seater with a huge, 960 litres of luggage space. And if you need to cart gear over people, the second row also folds flat to open up 1960 litres of space.

Up front, the feeling of spaciousness is amplified due to the low scuttle height and what the aviation industry calls the glass cockpit (no analogue dials or gauges at all). The 15.6-inch central info-screen runs the usual apps and control displays but, thankfully, the climate control touch-controls are tethered to the bottom of the screen, so they’re always visible regardless of what else is going on.

The 10.2-inch driver’s display adds a head-up function in Premium trim and displays the usual array of information required to operate the vehicle. But even better is the steering wheel which features a thick, well-padded rim that looks and feels pretty luxe. It also houses the usual buttons for stereo, phone and cruise-control functions.

A really nice touch is the addition of an extra set of tilt controls on the inside of the passenger’s front seat, allowing the driver to control that seat to allow people in or out without leaving their own seat. Nice one.

It is, of course, the centre row of seats that will make or break a car like this for many families. Even though many clans will not use the rearmost seat much of the time, the central row will get a huge workout. So it’s nice to see that leg, foot and headroom are all sufficient for even growing teenagers. Again, the car’s overall length appears to be the key, but it’s also worth noting the centre row seat is comfy and supportive. The outboard positions in the second row also feature heating and ventilation functions.

The third row, however, follows SUV tradition by being strictly for smaller kids. Access past those huge wheel arches is tight, and once you’re in, there’s a combination of dark trim and tiny windows to limit joy.

While it won’t matter to many buyers, the front-drive Sealion 8 is rated to tow 1800kg with a braked trailer, and up to two tonnes in the all-wheel drive version. But there’s no spare tyre fitted, and roadside flats need to be addressed by the included tyre repair kit.

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.

BYD has managed to keep a lid on the price of the entry-level version of the Sealion 8, by specifying it with front-wheel drive rather than the all-wheel drive of the other two variants. It still gets the same driveline beyond the lack of a driven rear axle, although battery capacity is the other difference.

As such, you’re looking at a 1.5-litre petrol engine (kind of the default powerplant for Chinese SUVs right now) with a turbocharger. With the 19kWh battery chiming in to power the electric motor, the driveline can achieve outputs of 205kW and 315Nm.

In the case of the AWD variants, the larger 35.6kWh battery and extra electric motor ups the potential outputs to 359kW and 675Nm which is a huge jump any way you look at it and gives the Sealion 8 a huge bandwidth when it comes to matching buyer performance aspirations.

All the variants have the potential for a claimed electric-only range of greater than 100km if owners use the plug-in facility to charge either at home or at work. For the AWD variants, the larger battery stretches the EV range to a claimed 152km. On longer journeys or whenever the battery has reached about 25 per cent capacity, the Sealion 8 acts just as any other hybrid with regenerative braking and electric assistance to aid performance.

In suspension terms, the BYD is pretty conventional but if you do pay the extra for the Premium variant, you’ll gain adaptive dampers.

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. 

BYD claims a range of more than 1000km for both variants of the Sealion 8, provided you start with a fully charged battery and a full 60-litre fuel tank.

The BYD can also make use of commercial fast-chargers and, when using the maximum 40kW on the FWD version and the 74kW possible for the AWD variant, the charging times from 30 to 80 per cent are both under 20 minutes. The Sealion 8 can also charge at 11kW on an AC socket and the vehicle also offers V2L (Vehicle to Load) capability, meaning it can power on-site work tools, camping gear or even your house at night.

Provided the EV battery is kept at 25 per cent capacity or above, BYD claims a 1.0-litre per 100km fuel consumption figure for the car based on the laboratory test. In the real world, the results will vary enormously depending on where you drive and how the car is used. Deplete the battery and continue to drive at highway speeds, and your actual fuel consumption might easily increase to many times that 1.0-litre claimed figure.

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.

The first thing you’re going to do in a Sealion 8 is wonder where the gearshift is. It’s a column-shift, but it's not only located where a traditional indicator stalk would be, it looks very much like one, too.

This promises two things. One, you’ll spend a few seconds finding it and two, you’ll try to turn the indicators on with it at least once every drive. (The real indicators are on the other side of the steering column.)

Another note to those test driving a Sealion 8. Sample the front-drive version first. (I’ll get to why in a minute.) When you do, you’ll soon figure out this is a driveline that prioritises electric running. That is, the petrol motor barely ever actually drives the wheels (only at full throttle and higher speeds). Any other time, if the petrol engine is running, it’s to charge the battery that keeps the electric motor purring away. This is how efficiency is defined by BYD.

You’ll also find that the Sealion’s acceleration is purposeful in that electric-motor way, but hardly startling. And when you do smash the throttle and force the petrol engine to drive the axle, you’ll notice that this takes a fair time to play out, and that when everything is grunting as hard as possible, the petrol engine is quite noisy and even a little harsh sounding. Use the driveline sensibly, though, and it’s all smooth and quiet, even if that then means you can hear a little suspension noise creeping into the cabin.

That done, you’re now free to drive the AWD variant. Why wait? Because this thing is seriously off the leash. Bear in mind that 359kW of power is getting on for the thick end of 500 horsepower in the old money, so even though the Sealion 8 is a hefty critter at about 2.5 tonnes, all that power and torque will get it from rest in under five seconds, or thereabouts. The relevance of this to family-car technology is hugely debatable, but it’s one heck of a party trick the first time you try it.

The huge torque also magnifies the Sealion 8’s natural tendency to lift its inside front wheel when accelerating out of a turn. A small tyre squeak can sometimes be heard before the traction control gathers it all together, but even the single-motor variant displays the same trait.

In steering and suspension terms, it’s probably fair to say the Sealion 8 doesn’t unlock any new depths of talent. The ride is pretty comfy but at the expense of body control and the steering points the wheels but doesn’t convey much else to the driver.

That said, the fact everything seems to be tuned to the same frequency means it all works okay. You don’t have too-fast steering fighting the tyres or too firm suspension upsetting the interior calm. Use it as a family would, and it’s 100 per cent fit for purpose.

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. 

Servicing any hybrid can be a bit more expensive thanks to the presence of two propulsion forms.

In any case, the Sealion 8 requires routine servicing every 12 months or 20,000km.

Warranty is BYD’s normal six-year/150,000km cover, although there’s also eight years and 160,000km of cover for the EV battery.

BYD also claims its 'Blade' battery technology is among the safest in the business, and says the design resists damage (and, therefore, the risk of fire) better than the competition.

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.
