BYD Sealion 6 vs Volvo XC90

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 XC90 Recharge makes a lot of sense for a family with a couple of kids, who live and spend most of their time in the city and surrounding suburbs.

You’ll need access to a power point for charging and you’ll have to do it regularly to get the best out of this SUV, but in return you’ll get effortless and efficient driving, along with the practicality and prestige which comes with any XC90. 

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.

Cars are like dogs in that a year for them ages them more than one for us. So, this current-generation XC90 which came out in 2015 is getting on in age. Still, the XC90 is a design lesson in how to defy the aging process because the styling even now it appears modern and beautiful. It’s also big, tough, and prestigious looking which is how the flagship SUV in a premium brand should be.

The Thunder Grey paint my test car wore (see the images) is an optional hue, and it suited the battleship size and personality of the XC90. The enormous 22-inch five -spoke Black Diamond Cut alloy wheels were standard and filled up those giant arches nicely.

Maybe it’s the minimalist styling which has kept the XC90 looking cutting edge, because even the interior looks like the inside of a very expensive psychiatrist’s office with those leather seats and the brushed aluminium trim.

The vertical display is still impressive even in 2021, and while fully digital instrument clusters are in everything these days the XC90’s has a prestigious look and matches the rest of the cabin in its colours and fonts.

As for the XC90’s dimensions, it’s 4953mm long, 2008mm wide with the mirrors folded and 1776mm tall to the top of its shark fin antenna.

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.

Clever interior packaging means the XC90 Recharge is more practical than many large SUVs. There are flashes of utilitarian brilliance everywhere from the children’s booster seat which pops out of the centre of the second row (see the images) to the way the XC90 can crouch down like an elephant to make it easier to load stuff into the boot.

The XC90 Recharge is a seven-seater, and like all SUVs with third rows those seats in the very back only offer enough room for kids. The second row is spacious even for me at 191cm tall with plenty of leg- and headroom. Up front as you’d expect has good head-, elbow- and shoulder room.

Cabin storage is good with two cup holders in each row (the third also has containers under the armrests) and there are large door pockets, a decent sized centre console box and a net pocket in the front passenger footwell.

The cargo capacity with all seats being used is 291 litres and with the third row folded flat you’ll have 651 litres of boot space.

Storage for the charging cable could be better. The cable comes in a stylish canvas bag that sits in the boot, but other plug-in hybrids I’ve driven do a better job of providing a storage box for the cable that’s out of the way of your regular cargo.  

The gesture control tailgate works with a foot swish under the rear of the car and the proximity key means you can lock and unlock the vehicle by touching the door handle.

The cargo area is filled with hooks for bags and a lift-up divider to hold items in place.

Four-zone climate control, four USB ports (two in the front and two in the second row) dark tinted rear windows and sun blinds top off what is a very practical, family SUV.

My family is small – there’s just three of us – and so the XC90 was more than what we needed. That said, we found a way to fill it with holiday gear, shopping, even a mini trampoline.

The XC90 Recharge lists for $114,990 making it the most expensive grade in the XC90 range.

Still, the value is excellent considering the number of features which come standard.

The 12.3-inch digital instrument cluster standard, so is the nine-inch vertical centre display for media and climate control, there’s also sat nav, a Bowers and Wilkins 19-speaker stereo, wireless phone-charging, four-zone climate control, power-adjustable front seats, proximity key with auto tailgate and LED headlights.

My test car was fitted with options such as the Nappa Leather perforated and ventilated seats in Charcoal ($2950), the Climate pack which adds heated rear seats and a heated steering wheel ($600), power folding headrests in the rear ($275) and Thunder Grey metallic paint ($1900).

Even at a grand total (before on-road costs) of $120,715 I think this is still good value.

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 XC90 Recharge (Volvo calls it this, so for simplicity let's do it, too) is an all-wheel drive SUV with a 2.0-litre four-cylinder supercharged and turbo-charged engine, producing 246kW and 440Nm, plus an electric motor which adds 65kW and 240Nm.

Shifting gears is an eight-speed automatic and acceleration is rapid at 5.5 seconds for the 0-100km/h sprint.

All XC90s have a 2400kg braked towing capacity.

The 11.6kWh lithium ion battery is located under the floor in a tunnel which runs down the centre of the car covered by the centre console and hump in the footwell of the second row.

If you didn’t realise, this is the type of hybrid you need to plug into a power source to charge the batteries. A power point is fine but a wall unit is faster.  If you don’t plug in, the battery will only get tiny whiff of charge from the regenerative braking and that won’t be enough to put a tiny dent in your fuel consumption.

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.

Volvo says that after a combination of urban and open roads the XC 90 Recharge should use 2.1L/100km. That’s incredible - we’re talking about a five-metre long, 2.2-tonne, seven-seat SUV here.

In my testing the fuel economy varied greatly depending on how and where I drove the XC90.

There was a week where I only drove up to 15km a day doing the day care drop-offs, the shopping, popping into work in the CBD, but all within 10km of my home. With 35km of electric range I found that I only had to charge the XC90 every second day to keep it topped up to full and, according to the trip computer, after 55km of travel I was using 1.9L/100km.

I recharged using the outdoor power point in my driveway and using this method would take just less than five hours to fully charge the battery from empty. A wall unit or fast charger will top the battery up much quicker.

The charging cable is long at more than 3m, and the flap on the XC90 is located on the front left wheel guard.

If you don’t have a way of charging the XC90 regularly then fuel consumption will go up, obviously.

This happened when our family took a break down the coast and the holiday house we stayed at didn’t have a power point within reach. So, while we had been charging the car regularly in the week beforehand with a few long trips thrown in on motorways, for the four days we were away I didn’t plug it in at all.

After 598.4km I filled it back to full at the petrol pump with 46.13 litres of premium unleaded. That comes to 7.7L/100km, which is still great fuel economy given that the last 200km would have been without charging.

The lesson is the XC90 Recharge is most fuel efficient on short suburban and city trips with daily or every second-day charging.  

A larger capacity battery would add more range and make this plug-in hybrid SUV better suited to people who live further out of the city and do more motorway miles.

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. 

We put more than 700km on the clock of the XC90 Recharge during the three weeks it stayed with my family, covering a lot of motorway miles, country roads and a stack of urban usage, too.

Now without sounding like one of the haters who hated on me the last time I test-drove a Volvo hybrid, you will need to charge the XC90 Recharge all the time if you want to get not only the best fuel economy, but also the best performance from the SUV, too.

There’s the extra oomph from the motor, when you have enough charge in the ‘tank’ but also the serene and smooth pleasure of driving in electric mode on city and urban trips.

That tranquil electric driving experience feels kind of at odds with a large SUV at first, but having now tested a few big family plug-in hybrids and EVs I can tell you it’s a more enjoyable one.

Movement is not only smooth, but the electric grunt provides a feeling of control with an instant response which I found reassuring in traffic and at intersections.

The transition from electric motor to petrol engine is almost seamless. Volvo and Toyota are only a couple of the few brands which seemed to have achieved this.

The XC90 is large and that presented a challenge when trying to pilot it into my narrow driveaway and in car parks, but light, accurate steering and excellent visibility with large windows and cameras galore helped there.

The auto parking feature works well even on the higgledy-piggledy streets in my neighbourhood.

Topping off an effortless driving experience is air suspension which provides a cushioned and composed ride, with great body control all while wearing those 22-inch wheels and low-profile rubber.

Volvo has for decades been a pioneer of safety systems to such an extreme that people used to make fun of the brand for being overly cautious. Well, take it from this helicopter parent: there’s no such thing as being overly cautious! Besides, these days all car brands are striving to offer advanced safety systems which the XC90 has had for years. Yep, safety is cool now. Which makes Volvo the Kanye of car brands.

Coming standard on the XC90 Recharge is AEB which works at city speeds to brake for pedestrians, cyclists, vehicles and even large animals.

There’s also lane keeping assistance, blind spot warning, cross traffic alert with braking (front and rear).

Steering support provides assistance during at evasive manoeuvre at speeds between 50 and 100km/h.

Curtain airbags cover all three rows and for child seats there are two ISOFIX mounts and three top tether anchor points in the second row. Note, there are no mounts or points for child seats in the third row.

A space-saver spare is under the boot floor.

The XC90 was given the maximum five-star ANCAP rating when it tested in 2015.  

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 XC90 is covered by a five-year, unlimited kilometre warranty. Two service plans are offered: three years for $1500 and five years for $2500.
