Hyundai I30 vs BYD Sealion 5

What's the difference?

The updated Hyundai i30 N Line doesn’t look like or perform like a base model.

You really do get bang for your buck here with its features. It’s a good-looking hatch that’s fun to drive in the city or open road and while the multimedia system is basic and occupants will be squished in the rear row, everything else is a big plus.

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 It makes a base-model Mitsubishi Eclipse Cross PHEV feel positively outdated and it’s $13,800 cheaper.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 design memo seems to be to make the i30 N Line look sportier and more purposeful.

They've nailed the design. The i30 is a good-looking hatch that looks like it has European styling.

The reshaped grille features new air intake vents, and stylish V-shaped daytime running lights. The rest of the body looks sharply dressed with new side skirts, reshaped bumper, black side mirrors, dual exhausts and 18-inch alloy wheels.

The cabin has been refreshed with a black headliner, upgraded leather and suede upholstery with contrasting red stitching and an N Line steering wheel and leather gear shifter.

The dashboard features new materials and additional soft touchpoints that make the interior feel like it's not a base model at all.

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.

Like most hatches, the front row of the i30 benefits the most when it comes to leg- and headroom. Taller passengers will be most comfortable up front as the rear row doesn't offer all that much legroom. It's squishy behind my driving position and I'm only 168cm tall!

Access however is decent for both rows because of the wide door apertures, but it's a low car to get in and out of because of the 140mm ground clearance. Expect a couple of grunts after a gym session.

The seats in both rows are fairly well-padded and offer the most comfort on shorter journeys. Even with the new powered lumbar support on the drivers seat, fatigue can set in quickly on a longer trip.

Individual storage is excellent throughout the car with a large glovebox that can hold a thick manual, middle console, phone tray, four cupholders, a drink bottle holder in each door, two net map pockets and even a sunglasses holder!

Other than the Kia Cerato, the i30 has one of the largest boots compared to its rivals, at 395L, and it’s enough for road trips and a decent grocery haul. The taller boot lip means you can stack items too but you don’t get a spare wheel in this model, just a tyre mobility kit. The base model also doesn’t get a powered tailgate, but the lid is not heavy at all to operate.

The new digital instrument cluster looks great but the multimedia system is basic and there’s no satellite navigation, so you're reliant on the phone mirroring apps but these maintain a strong connection. The radio is a hit or miss but that’s typical for the grade level.

Charging options are great for a base model with a single USB-A port, three USB-C ports and 12-volt sockets, and a wireless charging pad to choose from.

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 updated i30 N Line has a new mild-hybrid powertrain that features a 1.5-litre 7 four-cylinder turbo-petrol engine and combines to produce 117kW and 253Nm of torque. This new combo means it has higher outputs than its nearest rivals and you get three drive modes, including Sport which makes those outputs feel even more prevalent.

Like its rivals, the i30 N Line is a front-wheel-drive, but it has a seven-speed dual-clutch transmission which can sometimes feel like it's confused in stop/start traffic.

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 new engine coasts in neutral when you’re not accelerating to improve efficiency and it works for that purpose as my real-world usage of 6.3L/100km isn't too far off the official combined fuel cycle figure of 5.6L.

Based on the official combined fuel cycle and 50L fuel tank, you should see a theoretical driving range of up to 893km, which is downright respectable.

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 new powertrain is impressively punchy and you almost feel like you’re driving a hot hatch when you hit the open road because it’s effortless to keep up and overtake when necessary. 

The steering is firmer than what you’d expect and that makes the car feel heavier than what it is. Cornering is great – barely any roll – but the suspension is not finely tuned, especially for regional roads. But the overall feel is sporty, so it’s forgivable. 

At lower speeds, the cabin is delightfully quiet and although the exhausts are thrumming with noise, you don’t really hear it! It’s only once you get on the open road that the road noise creeps up but you can hold a convo without raising your voice, so that’s still good.

The i30 is pretty low to the ground and that makes it easy to scrape the bottom of it, especially when you have a full car load, so take ramps and bumps at a slight angle.

Hatches are always the best for parking because you can park ‘em anywhere! The i30 N Line has front and rear parking sensors and a decent reversing camera, so it’s extra easy.

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.

Hyundai offers the i30 with a five-year/unlimited km warranty, which is a normal term for the class and you can pre-purchase three-, four- or five-years worth for servicing and the five-year option cost $1795, which is competitive. 

Servicing intervals are okay at every 12 months or 10,000km, whichever occurs 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.
