Volkswagen Id.4 vs BYD Sealion 6

What's the difference?

It’s been a long wait for the Volkswagen ID.4 Pro, but it’s one that’s paid off. It's an electric SUV that delivers on the essentials - comfort, smart features, and an effortless driving experience. But it also keeps charging times, range, and running costs firmly in the 'very liveable' camp. The ID.4 Pro manages to feel polished and personable, which is a great combination.

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 ID.4 Pro leans toward the pillowy end when it comes to exterior shape but it’s as cute as a button. Soft curves aren’t uncommon in this segment, and the overall effect is friendly yet grown-up.

A chrome accent strip running from the roof to the C-pillars adds interest, as do the matrix headlights, which look a bit like Transformer eyes. They’re adaptive too, so they put on a little light show when you start the car - a fun party trick.

Around the back, customisable rear light profiles will earn nods from the cooler kids.

Step inside and the cabin shines. Space is generous, and any 'cute' impressions fade fast as it’s clear this cabin means business.

Visually, it’s slick and considered, with premium materials like leather, suede, and synthetic trims setting the tone. There’s still a touch of Volkswagen fun, though. Look out for the Pause and Play icons on the brake and accelerator pedals.

It feels airy and open, especially with the panoramic sunroof option, and both displays are impressively sharp. You might expect a larger digital cluster, but the 5.3-inch instrument screen does a surprisingly good job, keeping things tidy and focused on the drive.

I'm also quite fond of the adjustable front armrests, which can be folded up and out of the way when not needed. A small touch, but it adds to the car’s flexible, family-friendly feel.

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.

The front row offers plenty of room for two co-pilots to settle in without bumping elbows. The seat padding is softer than you’d usually expect from Volkswagen, and with the extendable under-thigh supports and added seat functions, the ID.4 Pro proves itself a seriously comfortable road-tripper.

In the back, space is generous, and my eight-year old appreciated the wide door openings and cushy seating. It’s best thought of as a very comfy space for two adults, with room for a third in a pinch.

That flat floor makes a noticeable difference for the middle passenger, giving them more legroom than usual. The 'two is best' idea also applies to child seats and while there are three top-tether anchor points, realistically, using more than two at once would be a squeeze. I had no trouble installing my booster this week, though it did block visibility out the back window.

Storage up front is a strong point, with a glove box, cupholders, bottle holders, and a generous centre console. The console houses the wireless charging pad, two USB-C ports, and a large cubby that swallowed gloves, snacks, and two pairs of glasses with cases which is perfect for keeping the cabin clutter-free.

Rear passengers are well looked after, too, with climate control, directional air vents, two USB-C ports, a fold-down armrest with cupholders, bottle holders in each door and map pockets. It’s all very family-friendly.

The 543L boot handled everything we threw at it this week. I like the adjustable floor height; set it higher to create a handy space for your charging cables, or lower it to maximise room. There’s also a hidden pocket under the floor for the tyre repair kit (no spare of any description).

You miss out on a frunk, but the powered tailgate and stretchy luggage net help keep things secure and easy to manage.

Tech-wise, it’s mostly intuitive. While my husband isn’t a fan of the touchpad climate and steering wheel controls, I find them pretty straightforward to use.

What does bug me, though, is the lack of built-in sat nav and wireless Apple CarPlay. I don’t like leaving my phone charging all the time, and even when you reconnect the cable, you have to manually restart CarPlay every time you get in. Hopefully that’s something Volkswagen irons out in a future update.

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.

Price is key to BYD’s success in Australia. Quite simply, the Chinese brand has undercut its rivals and consumers have responded to that, unsurprisingly in these tough economic times. The Sealion 6 follows the same path blazed by the Atto 3, Dolphin and Seal, offering plenty of vehicle for your money.

BYD Australia has kept it really simple, offering just two models - Dynamic and Premium - with very similar specification and separated primarily by powertrains.

The Dynamic is a less powerful, two-wheel drive option, while the Premium gets more grunt and all-wheel drive; but we’ll detail that later.

Both the Dynamic and Premium come with 19-inch alloy wheels, power-operated tailgate, a panoramic sunroof, powered front seats that are heated and cooled, a 15.6-inch touchscreen, Infinity premium audio, two wireless phone chargers and wireless Apple CarPlay and Android Auto.

The only non-powertrain difference between Dynamic and Premium is a head-up display on the latter model.

One noticeable absence from the Sealion though is a spare tyre. There’s not even a space-saver, just a tyre repair kit, which is disappointing and out of touch with the unique demands of the Australian market.

The Dynamic is priced from $48,990 (all prices exclude on-road costs), while the Premium starts at $51,990.

To put that into context with its competition, the Toyota RAV4 Hybrid range begins at $42,250 for the GX and stretches to $51,410 for the range-topping $51,410.

While, if you’re looking at an electric alternative, the Tesla Model Y currently starts at $55,900. The most direct rival, however, is the Mitsubishi Outlander PHEV which is only available with all-wheel drive and stretches from $57,290 to $73,790 across five variants.

The ID.4 Pro is fully electric and rear-wheel drive with a single motor on the rear axle producing 210kW and 545Nm. That supports a claimed 0-100km/h sprint of 6.7 seconds, which feels satisfyingly swift for a mid-size SUV.

There’s instant torque for easy overtakes and the RWD keeps things balanced and composed. You also get a choice of drive modes to suit your style, and regenerative braking helps recover energy smoothly. It’s subtle, but effective enough to make city driving feel more efficient.

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 ID.4 Pro is fitted with an 82kWh lithium-ion battery and offers a WLTP driving range of up to 544km, which is impressive for the segment.

Official combined cycle (urban/extra-urban) energy consumption is rated at 16.7kWh/100km, and around town, where regenerative braking works harder, you’re unlikely to feel any range anxiety.

If, like me, you do a lot of regional driving or longer trips, you might find yourself keeping a closer eye on the gauge. My real-world consumption sat closer to 20kWh/100km, which still leaves you with solid usable range, but it’s something to factor in.

Charging is straightforward, with a Type 2 CCS port that accepts up to 175kW on a DC fast charger and 11kW on AC.

Both figures are useful and on a fast charger you can expect a 10-80 per cent top-up in around 30 minutes which is quick enough to squeeze in a coffee break or snack stop, even with a kid in tow.

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.

The ID.4 Pro is simple to operate, and aside from the instant power delivery and lack of a traditional start/stop button, it behaves much like a combustion-powered car.

That makes it a great entry-point for anyone new to EVs because it's familiar, but has just enough electric quirk to keep things interesting.

I miss a true one-pedal driving experience in city traffic, but the set-up still works well. Regenerative braking isn’t particularly strong, but you can toggle between 'Drive' and 'B' mode, with the latter offering a bit more resistance. I’ve kept it in B mode most of the week as the extra feedback just feels nicer underfoot.

This week’s testing included winding mountain roads, regional backroads, as well as freeway stretches and the ID.4 handled it all with confidence. There’s enough precision in the corners to keep things fun, and it always feels well planted.

The suspension strikes a middle ground - not ultra-soft, but still comfortable. You’ll feel some of the sharper bumps, but most surfaces are smoothed out well, and the cabin stays quiet even at higher speeds. Ride comfort has clearly been a priority and it pays off.

From the driver’s seat, visibility could be better. The rear window is narrow, and the thick pillars don’t help, so I found myself relying quite a bit on the camera system when parking or manoeuvring.

That said, the ID.4’s size and clear 360-degree camera system make it incredibly user-friendly in tight spaces. Whether parallel parking or squeezing into small car parks, it isn't stressful to park.

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. 

Both Sealion 6 variants come equipped with autonomous emergency braking, front and rear cross-traffic alert/braking, 'Forward Collision Warning', 'Rear Collision Warning', lane departure warning/prevention, blind-spot detection, traffic-sign recognition, door-opening warning, trailer stability control, auto high beam, a 360-degree monitor, adaptive cruise control as well as front and rear parking sensors. Plus, it can even detect if you’ve left a child or pet inside the car.

ANCAP had not crash-tested the Sealion 6 at the time of publication, but with its comprehensive list of safety items it should tick most of the boxes when it comes to protecting its occupants and pedestrians.

The ID.4 Pro comes with a five-year/unlimited kilometre warranty, which is standard across the Volkswagen range, while the battery is covered for eight years or 160,000km, giving buyers a little extra peace of mind when it comes to long-term EV ownership.

Volkswagen also offers a 10-year capped-price servicing program, which is excellent for the segment.

The total cost comes to $2890 over the full term, and the service intervals are spaced every two years or 30,000km, whichever comes first.

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.
