Kia EV9 vs. Hyundai Ioniq 9: Same Platform, Bigger Battery, and a Price Gap That Flips
Hyundai Motor Group's three-row EV twins share a platform but not a battery. Trim for trim, the Ioniq 9 often gives you more range for little or no extra money.
The Kia EV9 and Hyundai Ioniq 9 share Hyundai Motor Group's E-GMP electric architecture, both come out of Georgia, and both seat six or seven. The Ioniq 9 carries a bigger battery and a longer body; the EV9 keeps a cheaper entry point. Our full rundown of 2027 EV9 pricing covers the Kia's changes.
The surprise is the money. Trim for trim, the price gap is smaller than the EV9's $54,990 starting price suggests, and in the middle of the lineup it runs the other way: the Hyundai is the cheaper car.
Same platform, different cars
The shared hardware is real. The Insurance Institute for Highway Safety applies the EV9's small overlap and side crash tests to the Ioniq 9, and both run 800-volt charging with the same 24-minute 10-to-80-percent claim on a 350-kW charger.
The Ioniq 9 is 199.2 inches long on a 123.2-inch wheelbase. The EV9 measures 197.2 inches on a 122.0-inch wheelbase. Every Ioniq 9 gets the 110.3-kWh pack; the EV9 uses 76.1 kWh in the base Light and 99.8 kWh everywhere else. They don't even share a factory. The EV9 comes from Kia's West Point plant, and the Ioniq 9 from the Hyundai Motor Group Metaplant America near Savannah.
The numbers side by side
Prices below exclude destination: $1,645 on the 2027 EV9 and $1,650 on the 2026 Ioniq 9, per Hyundai's July 29 price sheet. EV9 range figures are Kia's targets, not EPA ratings; the Ioniq 9's are EPA estimates.

Three matchups that matter
Entry: EV9 Light Long Range ($57,990) vs. Ioniq 9 S ($58,955). Both are rear-drive, with 258 lb-ft. For $965 more, the Hyundai brings a 335-mile EPA rating against the Kia's 305-mile target, 14 more horsepower, and a 3,500-pound tow rating where the EV9 stops at 2,000. Below both sits the EV9 Light at $54,990, with a 230-mile target.
Middle: EV9 Wind ($64,090) vs. Ioniq 9 SE ($62,765) or SEL ($66,320). Here the price order flips. The all-wheel-drive Ioniq 9 SE costs $1,325 less than the Wind and is rated for 320 miles, versus the Wind's 283-mile target. It also tows 5,000 pounds to the Wind's 3,500. The Wind answers with 379 hp to the SE's 303. If you'd add the SEL's heated second row and surround-view camera, the Hyundai runs $2,230 more than the Wind.
Top: EV9 GT-Line ($71,990) vs. Ioniq 9 Performance Calligraphy ($74,990). The Hyundai's $3,000 premium buys 422 hp to the Kia's 379, the same 516 lb-ft, and 311 miles against a 280-mile target. One step down, the 2027 EV9 Land now includes the Nightfall package and its 516 lb-ft as standard for $69,990, which is $1,260 under the Ioniq 9 Performance Limited.
What the extra Hyundai money buys
Mostly battery. Every Ioniq 9 gets 10.5 kWh more than the EV9 Long Range, and it shows in range at every trim and in towing on the cheaper versions. The Hyundai also has the bigger cargo area at all three seat positions, by 1.7 to 5.2 cubic feet, plus 1.2 inches more third-row legroom than the EV9 with its bench seat.
The trade-off is mass. Depending on the trim pairing, the Ioniq 9 weighs roughly 30 to 200 pounds more than the comparable EV9, so its efficiency edge is smaller than its battery edge.
What the Kia gets right
Price of entry: the EV9 Light is the only version of either car under $55,000, and the 2027 Land is the better-equipped upper trim for the money.
Charging is close to a tie. Both have a native NACS port: Hyundai fitted one from launch, and Electrek reports every 2027 EV9 has one built in. We covered how Kia's Supercharger access works in our Lexus RZ vs. Kia EV6 comparison.
Five years of home charging
We used 15,000 miles a year and the U.S. Energy Information Administration's 18.2-cent forecast for residential electricity, the same inputs as our used EV vs. gas car cost math. Ioniq 9 figures are converted from Hyundai's EPA MPGe ratings; Kia hasn't published 2026 or 2027 EV9 efficiency, so we used the 2025 EV9's EPA ratings.
- Ioniq 9 S (92 MPGe, about 36.6 kWh/100 mi): about $5,000 over 75,000 miles
- EV9 Long Range RWD (38 kWh/100 mi, 2025 EPA): about $5,190
- Ioniq 9 Performance (85 MPGe, about 39.7 kWh/100 mi): about $5,410
- EV9 GT-Line (42 kWh/100 mi, 2025 EPA): about $5,730
The Hyundai comes out $190 to $320 ahead over five years. Discounts will matter far more.
Deals: check the dates
Electrek reported up to $10,000 in customer cash on the 2026 EV9 in October, or 0% APR with $5,000 in bonus cash, and a $399 lease on the Light Long Range with $4,999 due. It reported up to $7,000 off the 2026 Ioniq 9, 1.9% APR for 60 months, and a $419 lease on the S with $4,999 due. We could not confirm either on the brands' offer pages. Electrek says Kia's EV offers run through November 2, and new programs from both brands are expected that week, so check before you sign.
Should you wait for the 2027 Ioniq 9?
Probably not for the hardware. Hyundai's July spec sheet for the 2027 Ioniq 9 lists the same 110.3-kWh battery, the same power ratings, and the same 335/320/311-mile estimates as the 2026. The headline addition is the Calligraphy Black Ink trim revealed in April. Hyundai hasn't published 2027 Ioniq 9 pricing, so a 2026 with October money on the hood is likely the better deal. Shoppers looking at Limited and Calligraphy trims should also know about the Ioniq 9 second-row seat recall, which is fixed with a software update.
What we don't know yet
- EPA ratings for the 2027 EV9; Kia's numbers are still targets.
- 2027 Ioniq 9 pricing and whether the freight charge changes again.
- November incentives for either SUV.
- Current-model-year NHTSA ratings for either car, which we could not confirm.
Which one should you buy?
For most families, the Ioniq 9. At the entry level and in the middle of the lineup, it gives you more range, more towing, and more cargo room for less money than, or close to, the comparable EV9. The SE versus Wind matchup is the strongest case: less money, 37 more miles of rated range, and 1,500 more pounds of towing.
The EV9 makes more sense in three cases: you want the lowest price of entry and can live with 230 miles; you're shopping the top end and prefer to save $3,000 with the GT-Line; or a dealer is still moving 2026 EV9s at a $10,000 discount, which erases the Hyundai's hardware edge. If you don't need to go electric, our ranking of three-row hybrid SUVs covers the gas-electric alternatives from both brands.
