The Ioniq 9 is Hyundai's seven seat electric SUV, and it is one of very few cars in its class where the manufacturer publishes the number a seven seat buyer most needs: how much boot you have left with all seven seats in use. The answer is 338 litres, and you will struggle to find it anywhere else.
Everything below comes from Hyundai's own UK Tech and Spec Guide and model pages, gov.uk's eligible list and Euro NCAP's own assessment. Where Hyundai's two documents disagree we say which one we are using and why.
Hyundai Ioniq 9
Seven seats as standard on every trim
The entry Premium
The one most people price first
The Calligraphy 427PS
The only one offering six seats
The Boot, In All Three States, Which Almost Nobody Publishes
If you are buying a seven seat car, the figure that decides whether it works is how much space is left behind a raised third row. Most manufacturers do not publish it and most reviews quote the wrong number. Hyundai does publish it.
| Hyundai's own row label | Capacity |
|---|---|
| Luggage capacity VDA, seats up, behind 3rd row | 338 litres |
| Luggage capacity VDA, seats up, behind 2nd row, 3rd row folded flat | 908 litres |
| Luggage capacity VDA, seats down | 2,419 litres |
| Front boot, Premium | 88 litres |
| Front boot, Ultimate and Calligraphy | 52 litres |
908 litres is Hyundai's figure for the space behind the second row with the third row folded flat, which is the car in five seat mode. With all seven seats in use you have 338 litres. Both are real and they answer different questions. If you are buying this car because it has seven seats, 338 is your number. All three figures are VDA measurements, which is worth noting because some rivals publish on a different standard and the figures are not directly comparable across standards.
Hyundai publishes 88 litres of front boot on the Premium and 52 on both the Ultimate and the Calligraphy. So the cheapest Ioniq 9 has the largest frunk, presumably because the dearer cars put equipment in the space. It is a small thing and nobody mentions it, and if you were planning on using the front boot for charging cables it is the sort of detail worth knowing before you order.
One inconsistency in Hyundai's own paperwork, for completeness. The seats down figure in the Tech and Spec Guide is 2,419 litres for the seven seat cars. Hyundai's website gives 2,494 litres for the six seat Calligraphy, a figure that appears nowhere in the spec guide. So the six seat car has 75 litres more with everything folded, and that only exists on one of Hyundai's two documents.
Towing, Where The Cheapest One Is 900kg Behind Everything Else
| Hyundai's own row label | 160kW rear drive | 226kW all wheel drive | 314kW all wheel drive |
|---|---|---|---|
| Max tow weight, braked | 1,600kg | 2,500kg | 2,500kg |
| Max tow weight, unbraked | 750kg | 750kg | 750kg |
| Gross train weight | 4,780kg | 5,800kg | 5,820kg |
Hyundai publishes 1,600kg braked for the 160kW rear wheel drive Premium and 2,500kg for both all wheel drive cars. That is a 900kg difference and it lands on the cheapest version, which is the one most people price first. If you tow anything substantial, a caravan in particular, the Premium may not be enough car and the step up to an all wheel drive version is not a small one in price. Unbraked is 750kg across the whole range, which is the usual figure. Tell us the trailer and we will confirm it against the exact derivative before anything is signed.
Worth pairing that with the range figures, because they pull in opposite directions. The Premium is the longest range Ioniq 9 at 385 miles and the weakest tow at 1,600kg. The all wheel drive cars tow 2,500kg and do 372 to 376 miles. There is no version of this car that gives you both the best range and the best towing.
Trims, Prices And The Headline Range Figure Hyundai Credits To The Wrong Car
| Trim | Seats | Power | WLTP range | Price |
|---|---|---|---|---|
| Premium 218PS rear drive | 7 | 160kW | 385 miles | £64,995 |
| Ultimate 307PS all wheel drive | 7 | 226kW | 376 miles | £73,920 |
| Calligraphy 307PS all wheel drive | 7 | 226kW | 372 miles | £76,435 |
| Calligraphy 427PS all wheel drive | 7 | 314kW | 372 miles | £78,235 |
| Calligraphy 427PS 6 Seat | 6 | 314kW | 372 miles | £79,235 |
| Calligraphy 7 Seat Black Ink | 7 | 314kW | 372 miles | £79,835 |
| Calligraphy 6 Seat Black Ink | 6 | 314kW | 372 miles | £80,835 |
Hyundai's website says up to 385 miles belongs to the Ultimate 218PS version with rear wheel drive and 19 inch wheels. Its own Tech and Spec Guide lists no 218PS Ultimate at all: the Ultimate there is 307PS all wheel drive at 376 miles, and 385 miles belongs to the Premium 218PS rear wheel drive. We have used the spec guide, because it is the document with the prices and the trim names in it, and flagged the website as inconsistent. The practical upshot is a good one for buyers: the longest range Ioniq 9 is the cheapest one.
Hyundai's website says seven seats are standard and six seats are optional on Calligraphy trim. The price table is more specific: six seats appear only against the 427PS Calligraphy variants, not the 307PS Calligraphy, and they cost £1,000. So you need the top trim and the most powerful powertrain to get the six seat layout, which puts it at £79,235 or £80,835 in Black Ink. If a six seat layout with second row captain's chairs is what you are after, that is a long way up the range from the entry car.
One scheduling detail worth knowing before you order. The Ultimate is a model year 2026 car while every other version in Hyundai's table is model year 2027. It is sitting in the middle of the price ladder as a run out listing, so availability on that one specifically is worth checking before you set your heart on it.
Charging, And The Home Charge Figure That Depends On Your Electricity Supply
| Hyundai's own row label | Time |
|---|---|
| Estimated public 350kW CCS, 10 to 80 per cent | 24 minutes, at 233kW maximum |
| Estimated public 50kW CCS, 10 to 80 per cent | 1 hour 43 minutes |
| Estimated wallbox 10.5kW three phase, 10 to 100 per cent | 10 hours |
| Estimated wallbox 7.4kW single phase, 10 to 100 per cent | 14 hours 42 minutes |
| Emergency three pin connector, 10 to 100 per cent | 44 hours 42 minutes |
Hyundai's row reads estimated public 350kW CCS at 233kW maximum, and its model page says the 800 volt system supports charging at up to 233kW using a 350kW ultra rapid charger. So 350kW is the charger you need to plug into and 233kW is what the car will actually draw. You will see this car described as a 350kW charging car and that is the charger's number rather than the car's. 233kW is still quick: 24 minutes from 10 to 80 per cent on a 110.3kWh battery is genuinely fast charging.
Most manufacturers publish one AC charging time and leave you to work out whether your house can deliver it. Hyundai publishes both: 10 hours on a 10.5kW three phase supply, and 14 hours 42 minutes on a 7.4kW single phase one. Nearly every UK home is single phase, so 14 hours 42 is the figure that applies to most people, and the 10 hour headline needs a supply you probably do not have. Credit where it is due, Hyundai is one of very few manufacturers giving you enough information to work that out for yourself.
Also published, and useful: the 50kW public charging time of 1 hour 43 minutes, which is the figure that matters on an older rapid charger, and vehicle to load output up to 3.6kW. Charging is CCS Combo and Type 2 across every trim.
Safety, And The Shared Testing Euro NCAP Declares Itself
| Euro NCAP, assessment published 10 September 2025 | Score |
|---|---|
| Stars | 5 |
| Adult occupant | 84 per cent |
| Child occupant | 87 per cent |
| Vulnerable road users | 77 per cent |
| Safety assist | 83 per cent |
| Variant tested | Ioniq 9 4x4 GLS, left hand drive, 70kW plus 160kW |
Euro NCAP's own release states that the Ioniq 9 shares a platform with the Kia EV9, that where performance is identical some tests on the Kia are used in this assessment, and the video on its page is described as showing the 2025 Kia EV9 tests. That is a legitimate and long standing Euro NCAP practice for cars built on shared platforms, and it is worth knowing when you read the scores, because they are not all derived from crashing an Ioniq 9. We would rather tell you that than present the numbers without it.
Euro NCAP lists three covered variants: an electric 160kW 4x2, an electric 70kW plus 160kW 4x4 and an electric 160kW plus 160kW 4x4. The first maps to the Premium and the second to the 226kW all wheel drive, so those two are covered beyond argument. The third is described by Euro NCAP as 160kW plus 160kW while Hyundai describes the 427PS car as 157kW front and rear. That is almost certainly the same car with the figures rounded differently, and because the two documents do not use the same numbers we are not going to state that the 427PS is covered as though Euro NCAP had said so in those words. The rating runs to the end of 2031 on the usual six year convention.
Worth noting what Hyundai does not publish: there is no battery capacity retention threshold anywhere in its documents, so the eight year battery warranty comes with a term but no percentage that would trigger a claim. Volkswagen publishes 70 per cent for comparison. On a lease that matters less than it would on a purchase, because you are handing the car back.
Warranty, And The Grant You Cannot Have
| Hyundai's own wording | Term |
|---|---|
| Vehicle warranty | Five year unlimited mileage warranty |
| Battery | Eight year 100,000 high voltage battery warranty |
| Anti perforation | 12 years |
| Vehicle health checks | Five year annual vehicle health checks |
| Electric Car Grant | Not eligible, and cannot be |
Unlimited mileage for five years is unusual. Most long warranties cap the mileage, often at 60,000 or 100,000, which is where they stop being useful to a high mileage driver. Hyundai does not. On a seven seat family car doing school runs and motorway miles, that is worth more than a longer headline figure with a cap attached to it.
The Ioniq 9 does not appear in either band of the government's eligible list, which we read in full on 11 November 2026. Hyundai is on the list, as the Ioniq 3, the Ioniq 6 Facelift and the Kona Electric, all Band 1. The reason the Ioniq 9 is absent is price: the scheme requires a final purchase price under £42,000 and the cheapest Ioniq 9 is £64,995. So there is no route to a grant on this car at any trim, and if you are weighing it against cheaper seven seat electric options, some of those will have £3,750 taken off and this one will not.
On company car tax, a fully electric car sits in the lowest benefit in kind band available, which is the main reason a car at this price works as a company vehicle at all. We are not going to print a percentage, because rates change each tax year and have been rising on a published schedule, so any figure here would be out of date within months. The thing to know is that benefit in kind is calculated from the list price, so the £15,840 between a Premium and a Calligraphy Black Ink follows the driver through every month of the agreement. Tell us the trim and we will get the current position confirmed in writing.
Is It The Right Seven Seater For You
The case for it is straightforward. Seven seats on every trim, a usable 338 litres behind the third row, 385 miles on the entry car, genuinely fast charging at 233kW and five years of unlimited mileage warranty. That is a strong set of numbers and most of them are published properly, which is more than can be said for a lot of this class.
The case against is price and towing. At £64,995 to £80,835 it gets no grant help at all, and the cheapest version tows 1,600kg where its own all wheel drive siblings manage 2,500kg. If you tow, the entry car is probably not enough and the step up is expensive.
Full current rates and the specification detail are on our Hyundai Ioniq 9 lease deals page. If you are weighing it against seven seaters that are not electric, our Sorento vs Santa Fe vs Kodiaq comparison covers the three large seven seat SUVs people ask about most, including which of them will not give you seven seats and a plug at the same time. Our electric car leasing page covers how electric leasing works more generally.
The rest of the Hyundai range, including the Ioniq 6 and the Kona Electric that do qualify for the grant, is at Hyundai lease deals.

Talk to LetsLeaseFrequently Asked Questions
338 litres, which Hyundai labels luggage capacity VDA, seats up, behind third row. That is the figure a seven seat buyer actually needs and very few manufacturers publish it. The number most reviews quote as the boot is 908 litres, and that is the space behind the second row with the third row folded flat, so the car in five seat mode. Seats down it is 2,419 litres. All three are VDA measurements, so be careful comparing them against a rival quoting a different standard.
It depends which one, and the gap is large. Hyundai publishes 1,600kg braked for the 160kW rear wheel drive Premium and 2,500kg for both all wheel drive versions. Unbraked is 750kg across the range. So the cheapest Ioniq 9 tows 900kg less than every other one, which catches people out because the Premium is the version most people price first. If you tow a caravan, the entry car may not be enough. Tell us the trailer and we will confirm the figure against the exact derivative.
The cheapest one. The Premium 218PS rear wheel drive is rated at 385 miles, against 376 for the Ultimate and 372 for every Calligraphy. Worth knowing that Hyundai's own website credits the 385 mile figure to an Ultimate 218PS with rear wheel drive and 19 inch wheels, and no such version appears in Hyundai's price and specification table, where the Ultimate is 307PS all wheel drive. We have gone with the specification guide, which is the document carrying the prices and trim names.
No, and it cannot. It does not appear in either band of the government's eligible list, and the reason is price: the scheme requires a final purchase price under £42,000 and the cheapest Ioniq 9 is £64,995. Hyundai is on the list with the Ioniq 3, the Ioniq 6 Facelift and the Kona Electric, all in Band 1. If you are comparing the Ioniq 9 against cheaper seven seat electric cars, some of those will have up to £3,750 taken off and this one will not.
24 minutes from 10 to 80 per cent on a 350kW public charger, with the car drawing up to 233kW. That distinction matters: 350kW is the charger you need and 233kW is what the car actually takes, and you will see it described as a 350kW car, which is the charger's figure. On an older 50kW rapid charger Hyundai publishes 1 hour 43 minutes for the same 10 to 80 per cent window.
14 hours 42 minutes on a normal UK home supply, which is a 7.4kW single phase wallbox. Hyundai also publishes 10 hours on a 10.5kW three phase supply, and three phase power is something nearly no UK home has. Credit to Hyundai for publishing both, because most manufacturers give you one figure and leave you to work out whether your house can deliver it. On a 110.3kWh battery an overnight charge from very low will not quite finish, so it is worth thinking about how you will actually use it.
Yes, but only at the top of the range. Seven seats are standard on every trim. Six seats appear only against the 427PS Calligraphy versions, not the 307PS Calligraphy, and they are a £1,000 option, which puts a six seat car at £79,235 or £80,835 in Black Ink. Hyundai's website says six seats are optional on Calligraphy trim without mentioning that you also need the more powerful powertrain.
Yes, published on 10 September 2025, scoring 84 per cent adult occupant, 87 per cent child occupant, 77 per cent vulnerable road users and 83 per cent safety assist. One thing worth knowing, which Euro NCAP states itself: the Ioniq 9 shares a platform with the Kia EV9 and where performance is identical some of the Kia's test results were used in this assessment. That is normal practice for shared platforms and it means not every score comes from crashing an Ioniq 9. The rating runs to the end of 2031 on the usual six year convention.
Hyundai's wording is a five year unlimited mileage warranty, plus an eight year 100,000 mile high voltage battery warranty, 12 years anti perforation cover and five years of annual vehicle health checks. Five years with no mileage cap is unusual and genuinely valuable on a high mileage family car, because most long warranties cap the mileage at the point they stop being useful. Hyundai publishes no battery capacity threshold, so the eight year battery cover has a term but no stated percentage that would trigger a claim.
Seven as standard, on every single trim, which is unusual in this class where the third row is often an option. Six seats are available too, with captain's chairs in the second row, but only on the 427PS Calligraphy versions and not the 307PS Calligraphy, and they cost 1,000 pounds. Hyundai's website says six seats are optional on Calligraphy trim without mentioning that you also need the top powertrain, so a six seat Ioniq 9 starts at 79,235 pounds rather than anywhere near the entry price.
They are different cars built on the same underpinnings, and Euro NCAP says so plainly in its own assessment: the Ioniq 9 shares a platform with the Kia EV9, and where performance is identical some of the Kia's crash test results were used in the Ioniq 9's assessment. That is normal and long standing practice for platform siblings. The two cars differ in styling, interior, equipment and how they are specified and priced in the UK, so they are worth pricing separately. Tell us which you are weighing up and we will quote both across our funders.
From 64,995 pounds for the Premium 218PS rear wheel drive, rising through 73,920 for the Ultimate and 76,435 for the Calligraphy 307PS, to 78,235 for the Calligraphy 427PS and 80,835 for a six seat Calligraphy in Black Ink. Those are Hyundai's own on the road prices from its Tech and Spec Guide. None of them attracts the Electric Car Grant, because the scheme requires a final price under 42,000 pounds. One scheduling note worth knowing: the Ultimate is a model year 2026 car sitting in the middle of an otherwise model year 2027 price list, so availability on that one specifically is worth checking before you commit to it.
LetsLease is a credit broker rather than the lender. We arrange the agreement and place it with a funder such as Lex Autolease, Novuna, Ayvens or Santander, and that funder owns the vehicle and holds the agreement with you. Because we work across several funders rather than one, we can compare how each prices the same car.
