Hyundai I30 vs BYD Seal 6

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.

The 2026 BYD Seal 6 proves a compelling offering at a time when cost and efficiency should be nearer the top of your new car consideration list. Not just for its long range, but its clever use of electrons and fuel to keep costs down even after the initial humble outlay.

It helps that the Touring Premium remains sub-$40,000, before on-roads, and offers plenty of features, a spacious interior and the right kind of drivetrain for everyday use in Australia.

While rivals like the Toyota Camry or Skoda Octavia are more polished and can almost compete on price, the BYD’s features and efficient PHEV powertrain will outweigh the brand names and more refined on-road behaviour of established rivals for, we would guess, a significant number of buyers.

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 Seal 6 Touring might be BYD’s best-looking car. It boasts a handsome wagon shape and its features don’t overdo the brand’s aquatic design language.

It’s not fussy with too many elements, but it’s not anonymous like some designs from China can seem on Australian roads. It’s definitely a BYD, but it’s not shouty about it. This means it should, visually at least, appeal to buyers who just want a sensible-looking sedan or wagon. Watch out again, Toyota.

The tail-lights and lower trim at the rear don’t leave too much blank space and the whole shape of the rear is sleek enough without cutting too far into the boot space.

Inside, the Seal 6 looks ‘classic BYD’, which isn’t a bad thing, but it’s not enormously interesting. It’s got enough points of difference from the layout Tesla has popularised and many Chinese brands now default to, but some daring style elements wouldn’t go astray.

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.

When it comes to practicality, a long trip will reveal plenty of things you might not notice day-to-day. Things like whether the seats really are comfortable, or how useful the cupholders are for different vessels.

Fortunately, the BYD Seal 6 holds up rather well in a few key areas.

Its seating adjustability and the seat itself are comfortable and easy to find the right driving position for an average-heighted man (me), though the bolstering on the seat won’t hold you in place tightly during spirited cornering.

The wheel is nice to hold and it’s easy to feel your changing position while steering, and the controls on it are clear, though more physical controls in the rest of the cabin would be an improvement.

The Seal 6 suffers from a reliance on the touchscreen that a number of car brands’ head designers and engineers are moving away from. The software’s menu system is not quite up to the task of being the only point of contact for functionality, as it requires scrolling through and can be distracting on the road. That will set off the driver monitoring, by the way.

Wireless Android Auto or Apple CarPlay and a wireless phone charger (which is out of the way) provide a good workaround and ensure your phone doesn’t die on a long journey.

There’s storage under the centre console where the cupholders are, a nice spot to keep things out of the way, plus there are USB-A and USB-C ports down there.

Behind the front seats, the second row isn’t lavishly spacious but allows a 178cm adult to sit behind their own seating position with kneeroom, headroom and shoulder room to spare. The sunroof makes it quite nice and light back there, too.

The second row seats fold down 60/40 to turn what was a 670-litre boot into a 1535L boot, though that seems to be measured to the roof rather than the tops of the seat-backs.

There is, disappointingly, no spare tyre under the boot floor, just a repair kit. I’d want a space-saver at least if I was travelling interstate (without a launch event support car).

The price tag attached to the Seal 6 adds to the growing pile of reasons why BYD has become the best-selling Chinese car brand in Australia.

Starting from $34,990, before on-road costs, the Seal 6 Sedan in Essential grade undercuts the Toyota Camry by $6000.

It features a decent list of standard equipment like wireless phone mirroring, synthetic leather upholstery, power-adjustable front seats and a 12.8-inch multimedia touchscreen.

But on launch, the Seal 6 Touring Premium was the focus and the only car available to drive.

Not only is it more powerful with a larger battery, but it starts at the same price as an entry-grade Toyota Camry - $39,990, before on-roads.

It comes with a big panoramic sunroof, heated and vented front seats and more improvements in the drivetrain department.

Given even traditional hybrid sedans like the Camry or Euro petrol sedans like the Skoda Octavia are effectively thousands more expensive, the plug-in hybrid Seal 6 already has an advantageous position in the market.

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 BYD Seal 6 has a 1.5-litre, four-cylinder petrol engine that helps a front-mounted electric motor drive those two wheels.

While the engine’s outputs are 70kW and 120Nm, the electric motor does the bulk of the work, with its 160kW and 260Nm outputs.

As such, the Touring we’re driving on this trip has total outputs of 163kW and 260Nm, with a claimed 0-100km/h time of 8.1 seconds feeling about right despite a peppy enough take-off from standstill.

The Seal 6 Sedan by comparison has the same engine but a less powerful electric motor, resulting in total outputs of 130kW and 210Nm.

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.

While the efficiency of a new car is sometimes difficult to test on a launch driving program due to car-swapping and unusual driving conditions like filming or dynamic testing, the car we drove for the full two-days was the same one, and only used for the journey.

That means its full trip of 996.3km (frustratingly not officially the 1000km promised) is a faithful example of what an interstate trip might mean for one or a couple of travellers.

Officially BYD claims a 0.8L/100km figure under NEDC testing for the Touring, but tests like those are misleading for plug-in hybrids as the battery does a lot of lifting.

So BYD tested before this event the claim it could drive a Seal 6 from Sydney to Melbourne, then double-checked it.

But Sydney to Melbourne on a single tank and a single charge turned out to be accurate, even after running down a significant chunk of the Touring’s claimed 100km of electric range as tested under WLTP conditions.

Unfortunately we couldn’t verify the total fuel used over the 996.3km traveled in car number four without first checking the tank was properly full and then refilling it again at the end.

Given the car estimated 68km left in the tank at the end of the trip, you could assume a fuel consumption reasonably below 6.5L/100km given the 65-litre tank still had some juice after near-1000km.

The trip computer’s claim of 4.5L/100km as an apparent cumulative total (including the several hundred kilometres of running-in before the launch) seems fair with a few extra battery charges under its belt prior to the drive.

Charging maxes out at 27kW on DC, or 6.6kW on AC by the way. DC charging should take less than an hour for the Touring’s 19kWh battery.

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.

If I had to buy a BYD today, the Seal 6 Touring makes a very strong case for itself in many ways. But unlike some of its stablemates, the way it drives is one of those ways.

The first day (of two) on the local launch saw a drive from Sydney to Albury on the Hume Highway, not known for being particularly dynamic. But the Seal 6’s relatively compliant suspension and lack of roaring road noise was welcome, at least for sections you couldn’t otherwise blame on the road’s surface.

The second day through some of Victoria’s high country and past Lake Eildon allowed the Seal 6 to prove it’s not a slouch, though calling it a sports car would be a stretch. Instead, the Touring's powertrain tune and apparently well-adjusted suspension and chassis meant spirited driving around twisting mountain roads and through winding backroads was easy, if not always exciting.

Big bumps would sometimes unsettle the Seal 6, but its predictability in most cases makes it feel safe and planted. The steering feel isn’t sportscar-like, but doesn’t leave you guessing and the same goes for pedal inputs.

I do wish the Seal 6 was a little more eager, but it’s not disappointing off the line and certainly has enough pep for daily duties.

There are drive modes, Eco, Normal and Sport plus a Snow mode, though the difference between the three doesn’t seem to be enormous. Eco definitely does what it says on the tin, though. The two regenerative braking levels also don’t seem to be incredibly different.

Also a let-down is the eagerness of the driver monitoring to direct your attention back to the road. When the ADAS (Advanced Driver Assistance Systems) settings were all active I started to tune the monitoring chime out because it would sound with every look at the multimedia screen.

The BYD Seal 6 boasts a maximum five-star ANCAP rating, with a fairly comprehensive safety suite including adaptive cruise control with forward collision warning and automatic braking intervention if a potential collision is detected. There’s also child detection to alert the owner or driver if a child is left in the car.

Seven airbags form the last line of defence in the Seal 6, including an important front-centre airbag.

Critically, these features are all standard across both variants.

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’s six-year/150,000km warranty is probably more than you’d need in terms of distance but is behind competitors who offer seven or eight years with unlimited kilometres, even 10 years conditional. An eight-year/160,000km warranty covers the battery, which is about par.

Finally, BYD has set servicing for every 20,000km or 12 months, with  the first five services totalling $2775, an average of $555 a visit. The fourth service is a hefty $1225, for reference.

BYD has more than 100 dealerships in Australia, with the brand still growing quickly.
