These two are separated by five kilometres of observed range — 455 against 450 — and by nine minutes at a rapid charger. If most of your driving fits inside one charge, the Model Y is the more efficient car and the cheaper one to run. If you regularly drive further than the battery goes, the Ioniq 5’s eighteen-minute charge is worth more than any range figure on this page.

Range: closer than the brochures suggest
On paper the Model Y claims 586 km WLTP against the Ioniq 5’s 570 km, and 327 miles EPA against 318. Observed, in mixed real-world conditions, they land at 455 km and 450 km. That is a five-kilometre difference between two cars whose batteries differ by five kilowatt-hours in the other direction — the Ioniq 5 carries 80 kWh usable, the Model Y only 75.
The Model Y gets the same distance from less battery because it uses 165 Wh/km against the Ioniq 5’s 178. That is a 7 percent efficiency advantage, and it is the whole reason the smaller pack keeps up. It also means the Model Y costs about 7 percent less to charge for every kilometre you drive, forever.
Charging: the Ioniq 5 wins this decisively
Eighteen minutes from 10 to 80 percent, against 27. The Ioniq 5 runs an 800-volt architecture and peaks at 263 kW; the Model Y is a 400-volt car peaking at 250 kW. The peak numbers look close. The time does not, because voltage changes how long high power can be held rather than how high it goes.
Nine minutes per stop is trivial once and material often. Two stops on a long drive is eighteen minutes; a family that does that trip monthly loses about three and a half hours a year to the difference.
Against that, the Model Y has the Supercharger network and routing that pre-conditions the battery on approach so it arrives ready to take full power. A slower car on a reliable network can beat a faster car on a queue. That is not a specification, and it is real.
What the Ioniq 5 has that the Model Y does not
3.6 kW of vehicle-to-load: household AC sockets fed from the traction battery, inside the car and at the charge port. It runs a fridge and lighting through a power cut, or tools on a site with no supply. The Model Y offers nothing equivalent.
Safety and recall record
Both hold five stars from NHTSA and five from Euro NCAP. On the recall record the raw counts are ten battery, electrical or powertrain campaigns for the Ioniq 5 against seven for the Model Y across the last four model years. Those numbers are not directly comparable — a manufacturer that recalls promptly and often looks worse than one that does not — so read the campaigns rather than the count. Both are linked on the individual car pages.
Which one should you buy
Buy the Model Y if most journeys finish inside one charge, if you want the lowest energy cost per kilometre, and if the Supercharger network covers where you drive. It is the more efficient car and efficiency is the gift that keeps giving.
Buy the Ioniq 5 if you regularly drive beyond one charge, if you want the flat floor and the more usable rear seat, or if vehicle-to-load solves a real problem for you. In the UK it is also around £8,500 cheaper at list.
Frequently asked questions
Which has more real-world range, the Model Y or the Ioniq 5?
The Model Y, by about five kilometres — 455 km observed against 450 km. That is close enough to be inside the noise of any single test, so treat them as equal on range and decide on something else.
How much faster does the Ioniq 5 charge?
Eighteen minutes from 10 to 80 percent against 27 for the Model Y, so nine minutes per rapid-charge stop. The Ioniq 5’s 800-volt pack holds high power across a wider state-of-charge window rather than simply peaking higher.
Which is cheaper to run?
The Model Y. At 165 Wh/km against 178 it uses about 7 percent less electricity per kilometre, which at 15,000 km a year is roughly 200 kWh. Put your own tariff into the running cost calculator for a figure in your currency.
Does either offer vehicle-to-load?
The Ioniq 5 does, at 3.6 kW. The Model Y does not.
Where these numbers come from
Every figure in the table above is credited to its source on the individual car pages: Tesla Model Y Long Range AWD and Hyundai Ioniq 5 84 kWh RWD. Range comes from EV Database and the US EPA, safety ratings and recall counts from NHTSA and Euro NCAP. How we handle estimates is set out on the methodology page.
