Volkswagen Id.4 vs BYD Sealion 5

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.

While the BYD Sealion 5 lacks the polish of some more established plug-in hybrids, it has a seriously compelling price advantage over some competitors. It makes a base-model Mitsubishi Eclipse Cross PHEV feel positively outdated and it’s $13,800 cheaper.

BYD's lack of ANCAP rating for the Sealion 5 and the uncertainty around it still being a new brand are downsides, even if BYD is quickly moving past the latter. But being the most affordable PHEV available while having this much showroom appeal is bound to work in the Sealion 5’s favour, just don’t expect a dynamic masterpiece once you’re out on the road.

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.

The BYD Sealion 5, from the outside, is inoffensive but also uninspiring. That’s likely not such a bad thing for a mid-size SUV – it’s rare you’re hearing someone talk about how beautiful the Mazda CX-5 or Toyota RAV4 is. 

Its quartet of colour palette options comes in on the safe side, too. Aurora White is standard, Atlantis Grey, Harbour Grey and Cosmos Black are cost-options.

Our test car is Atlantis Grey, which is interestingly quite blue. 

The relatively upright shape is a slight departure from the more ‘aquatic’ silhouettes of BYD’s line-up, but the front grille and light layout are decidedly in step with the brand’s oceanic design language. There’s a bit going on, you could say.

The slimline tail-lights are the rear, especially from a three-quarter angle to the side, look attractive and help break up the rear without looking messy.

The Sealion 5’s design is overall net-good, but it’s inside where the mid-sizer feels like you’re getting plenty for your dollar.

The seats, despite the leather fakery, feel like decent material, and the layout uses buttons and physical controls cleverly without feeling outdated.

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.

To actually interact with the interior is, at times, another story. BYD’s tech interface is generally easy to manage, but could be simpler when it comes to navigating menus for the sake of driver distraction.

While larger text and buttons would be welcome, the multimedia system is easy to use when parked, and the functionality is impressive for the price point.

Winning more points for the Sealion 5, though, are the physical controls – buttons and the traditional gear selector – which make the cockpit much more intuitive while on the move.

Ergonomically, though, the adjustment between the steering wheel and driver’s seat could do with some work, as I found it difficult to find a truly comfortable driving position. This is coming from someone 178cm tall, a very normal height in Australia.

Better adjustability on the steering column would be helpful, as it’s something I’m not sure I’d ever get totally used to.

Visibility and physical space inside the Sealion 5 is impressive, though. The car is 4738mm long, 1869mm wide and 1710mm tall, and the roof and window lines don’t swoop too aggressively towards the rear.

There are low window shoulders even into the rear, so light isn’t at a premium, though under-leg support could be better on the pew.

It’s otherwise un-cramped. The 2712mm wheelbase means decent legroom for second-row folk, plus behind the 60/40 split-fold seats there’s 463 litres of space for luggage. That becomes 1410L with the seats folded.

There’s unfortunately no spare tyre, just a tyre repair kit.

The BYD Sealion 5 Essential kicks off from $33,990 before on-road costs, four big ones less than the Premium ($37,990). We’re focusing on the Essential today, but don’t think that means a shallow list of features.

As you’d expect from BYD if you’ve been paying attention to the Chinese brand in its emergent years, the Sealion 5 comes with more than $34K would normally get you – a 10.1-inch central multimedia touchscreen, an 8.8-inch driver display, synthetic leather upholstery, dual-zone climate, a six-speaker sound system, wireless Android Auto and Apple CarPlay, USB-A and -C ports front and rear, digital radio and keyless entry.

On the outside, LED headlights and tail-lights are the same for both variants.

Both also have 18-inch wheels, not unwelcome for the benefits of on-road comfort.

Consider that the most popular SUV in the country, the Toyota RAV4, costs at least $45,990 without the benefit of a plug-in drivetrain (yet) and comes with, on paper, a more sparse list of features.

The closest PHEV competitors are still more pricey, including the Geely Starray ($37,490) and Chery Tiggo 7 ($39,990), and arguably lack the brand power BYD has come to enjoy.

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.

The Sealion 5’s front wheels are driven by a combined maximum of 156kW thanks to a 1.5-litre four-cylinder petrol engine (145kW/300Nm) and a permanent magnet synchronous motor (72kW/122Nm).

BYD claims a 0-100km/h sprint of 7.7 seconds for the Sealion 5 Essential, four tenths faster than the Premium despite only a 61kg difference in kerb weight.

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.

With a charged 12.9kWh lithium iron phosphate (LFP) battery and a full 52-litre (95 RON minimum) fuel tank, BYD reckons the Sealion 5 Essential can cover 1001km under NEDC testing, which is optimistic. It claims 71km can be done on EV power alone.

Not only due to the lenient nature of NEDC testing (WLTP is more common and usually results in lower ranges), but the reality is that once the battery is flat, the engine is doing a lot more work.

Charging is slow, limited to 3.3kW (AC only), which should take between 4 and 5 hours to charge from the lower end of the gauge for the battery size. Given most PHEV owners will do this overnight at home, that’s certainly not the end of the world.

Claimed consumption figures are 1.2L/100km with more than 25 per cent battery charge, or 4.5L/100km when it dips below that.

Realistically you could do sub-50km trips and use no fuel, or never plug your Sealion 5 in and see fuel consumption soar. In any case, anything close to 1001km in a single run is extremely unlikely.

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.

You might expect a car at this price, regardless of its drivetrain, to be underwhelming from behind the wheel.

That, then, makes it even more pleasantly surprising that the BYD Sealion 5 is actually rather competent. Not massively exciting or dynamic, but certainly not a disappointment.

The Sealion 5 is, save for a couple of arguably minor annoyances, quite easy to get used to and drive.

Firstly, when making proper use of its electric power, the drivetrain provides enough shove for its intended use. It’s not overly powerful, but you won’t have trouble overtaking. It’s the same with most of the inputs, the steering is light but not completely numb – again about right for how the Sealion 5 will be driven.

Perhaps its biggest departure from expectations based on other cars from China is its suspension is on the stiffer side of things, but again it’s not unruly or too rugged. In fact, it does provide a better sense of control than many of its compatriots.

Again, the biggest issue with the Sealion 5 day-to-day is its driving position, the steering column adjustment isn’t up to scratch and there’s not really a perfectly comfortable seating position (I’m a very standard 178cm).

On long trips, you might also find the engine gets quite noisy once the battery power is gone as it works hard to pull the mid-size SUV along under acceleration.

Its driver-assist systems are, you might be pleased to hear, on the calmer side of things – BYD is getting better at calibrating its safety features and I didn’t find myself rushing to switch it all off as quickly as usual.

It can still be a bit too persistent in its lane-keeping, but it’s a big improvement on the way things were.

There’s no ANCAP rating for the Sealion 5, but the list of safety kit isn’t lacking on paper.

BYD lists seven airbags ,including full-length side-curtain bags and an important centre airbag, plus there’s a whole suite of tech that’s, as noted, better behaved than past driver-assist systems from BYD.

The Essential only misses out on a surround-view parking camera and front parking sensors, both arguably important safety features for parents, but the rest of the list is the same as the Premium including adaptive cruise control, lane-keep and lane departure assist, traffic sign recognition, blind-spot monitoring, rear cross-traffic alert with rear AEB (as well as front AEB, of course) and tyre pressure monitoring.

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 has a six-year/150,000km warranty, which is probably more than you’d need in terms of distance but is behind many competitor brands’ timelines – seven to 10 years is becoming the norm, even if it’s conditional.

An eight-year/160,000km warranty covers the battery, which is about par for the industry.

Servicing for the first five proper services ranges from between $285 and $930, plus there's a free check-up six months into ownership and a total cost over the span of $2355 – an average of $471 per service.

BYD has just over 100 dealerships in Australia, so finding one for servicing shouldn’t be too challenging.
