The BYD Seal is rated 570 km on the WLTP cycle, the Hyundai IONIQ 6 614. A 10–80% stop takes 37 minutes in the BYD Seal and 18 in the Hyundai IONIQ 6. Every figure below names the badge it belongs to, and the three tools further down turn the same numbers into a charging race, a road trip and a yearly bill.

The short answer

The Hyundai IONIQ 6 is the quicker car to charge.

1

The Hyundai IONIQ 6 is rated 614 km against 570 — 44 km, 8% further. It uses 14.6 kWh to cover 100 km where the Hyundai IONIQ 6 needs 13.7.

2

A 10–80% stop takes 18 minutes in the Hyundai IONIQ 6 and 37 in the BYD Seal. On a 50 kW post it is 70 and 65 minutes, so most of the advantage disappears at a slow site.

3

The BYD Seal is the cheaper to buy, listed from A$49,888 against A$72,000 for the Hyundai IONIQ 6 — A$22,112 at the starting point, before on-road costs.

Charging, raced

Two cars, one post, same clock

Charging speed is a station number and a car number, and the smaller one wins. Set the post and both cars fill against the same clock — the interesting part is not who wins, it is how much of the gap a slow post takes away.

Each car is modelled on its own published 10–80% time, which gives an average power over that window: 94 kW for the BYD Seal, 181 kW for the Hyundai IONIQ 6. A post above that average changes nothing; a post below it sets the pace.

Hyundai IONIQ 6CCS222min
BYD SealCCS237min

At 150 kW, going from 10% to 80% takes 37 min in the BYD Seal and 22 min in the Hyundai IONIQ 6 — a gap of 15 minutes. The station is capping the quicker car here, so the gap is narrower than the peak figures suggest — at a faster post it widens again.

Every figure

The numbers, with the badge attached

A tick marks a figure that is simply more useful — more range, less energy per 100 km, a faster stop. Rows without a tick are different, not better: a bigger battery, a taller body and a heavier car are all trades, and this page does not pretend otherwise.

How to read the mixed rows. Range, efficiency, battery and charging come from one badge — the longest-range version of each car's current model year, not the longest range it has ever been rated at. The catalogue stores one record per badge, so where two figures come from different badges the row names the one it used.

What WLTP is not. It is a laboratory cycle at a fixed temperature, with the air conditioning off and a gentle acceleration profile. It exists so two cars can be compared on the same test, not so a driver can predict a highway run. Expect less on a 110 km/h trip, and less again in winter.

What this page does not claim. No ANCAP crash rating: the catalogue carries none, and a column of dashes would read like a failure rather than a gap. Prices are manufacturer list before on-road costs; the drive-away band appears only where the feed publishes one.

Your numbers

What this pair costs you, on your drive

Two questions decide most purchases: how often you stop, and what the year costs. Both are arithmetic on the figures above, so change the inputs and the answer changes with you.

The drive

Starts full, arrives at 10%, charges back to 80% at each stop, and assumes a highway range of 85% of the WLTP figure.

The year

Energy at the wheels from the WLTP label, priced at the tariff you pay. Home charging is usually cheaper than the directory's median.

The trip model ignores charger detours, queueing and the last 10% of the pack, which is slow on both cars. The yearly cost is energy only: no session fees, no idle fees, no home-charger installation, and no petrol car to compare against.

Your priorities

A verdict you can argue with

There is no single winner, only a winner for a set of priorities. Move the sliders and the weighting changes — nothing here is a magazine score, and the page never hides the numbers it is built from.

Weighted result

Hyundai IONIQ 6

wins 4 of 6 measures on these weights

BYD Seal24%
Hyundai IONIQ 676%

Each measure is scaled between the two cars, so a weight of 5 means “this is the thing I care about” and 0 means “I do not care at all”. The scores are relative, not a rating out of ten.

Questions

Short answers, then the reasoning

Every figure here comes from the same data as the rest of the page. Where the data cannot answer, the page says so instead of guessing.

Still unsure about a term? The connector guide covers the plugs, and the vehicle guide the rest.

Which has more range, the BYD Seal or the Hyundai IONIQ 6?

The Hyundai IONIQ 6. The BYD Seal is rated 570 km and the Hyundai IONIQ 6 614, each on the longest-range badge of its current model year — MY25–MY26 Premium and MY25 Long Range RWD respectively. WLTP is a laboratory cycle run at a fixed temperature with the air conditioning off, so treat the figure as a way to compare one car with another rather than a prediction for a highway run in summer.

Which charges faster?

The Hyundai IONIQ 6. Going from 10% to 80% takes 37 minutes in the BYD Seal (150 kW peak) and 18 in the Hyundai IONIQ 6 (350 kW peak). At a slow post the station becomes the limit and the gap narrows, because the slower car is short of power rather than short of time.

Do they use the same plug?

Yes. Both list CCS2 for DC fast charging, so either car can use the same sites without an adapter. An adapter still cannot raise the power a car will accept.

Which is cheaper to run?

The Hyundai IONIQ 6, by about A$67.50 a year at 15,000 km and A$0.50 per kWh. It uses 13.7 kWh per 100 km against 14.6. That is energy only, at the wheels: session fees, idle fees and home-charger installation are not in it.

Which has more space?

The Hyundai IONIQ 6: 400 L of luggage space against 401 L. Makers measure boot volume by different conventions — some to the window line, some under the parcel shelf — so read the direction as reliable and the size of the gap as indicative.

Which is cheaper to buy?

The BYD Seal is the cheaper of the two, listed from A$49,888 against A$72,000 for the Hyundai IONIQ 6 — A$22,112 between the two starting prices. Both are manufacturer list prices before on-road costs, options and any incentive, so a dealer's drive-away number will differ.
