We Tested the Hyundai Ioniq 5’s New Battery, Which Charges Faster and Delivers More Real-World RangeCar and DriverJack FitzgeraldFri, September 18, 2026 at 6:30 PM UTCAdd us on GoogleIs the Ioniq 5's Bigger Battery Better? We Tested ItHyundaiThe 2025-and-newer Hyundai Ioniq 5 comes with bigger batteries that charge faster and provide more range—and we've tested the real-world results.The EV SUV's standard pack grew from 58 to 63 kWh, while the larger one went from 77 to 84 kWh.In our testing, the new long-range pack added 50 miles of range, enabled a higher peak charge rate, and reduced overall charging times versus the older version.Welcome to Car and Driver's Testing Hub, where we zoom in on the test numbers. We've been pushing vehicles to their limits since 1956 to provide objective data to bolster our subjective impressions (you can see how we test here).Every Hyundai Ioniq 5 from the 2025 model year onward has a larger battery than the 2022–24 models. To see how the new hardware affects the electric SUV's range and charging times, we ran it through our comprehensive testing regimen. The real-world results were noteworthy. For instance, the bigger battery can now charge from 10 to 90 percent in less time than the old pack, this despite needing more juice to fill its extra capacity.Michael Simari - Car and DriverWhen we first got our hands on the Ioniq 5, we tested a 2022 all-wheel-drive Limited model equipped with the long-range battery. That model managed 210 miles of range on our 75-mph highway route. While the range number wasn't particularly impressive, the Ioniq's charging numbers were superb for the time. When hooked up to a DC fast-charger, the '22 Ioniq took just 33 minutes to go from 10 to 90 percent—an addition of 64.5 kilowatts. Charging peaked at 231 kilowatts and averaged 117 kilowatts, with 150 miles of range added in 23 minutes.AdvertisementAdvertisementWhile those charging figures were mighty impressive a handful of years ago, they're more commonplace in 2026. Fortunately, Hyundai improved the Ioniq's performance by a commensurate amount. We got our hands on a 2026 all-wheel-drive Limited—a direct replacement for our initial tester—and achieved 260 miles of range on the same 75-mph highway-range route.Things improved on the charging front too. For starters, every Ioniq equipped with the newer packs also adopts a NACS port, so finding a charger is more convenient than before thanks to Tesla's vast Supercharger network. Even though the new battery is over 8 percent larger, our 2026 test car cut down the 10-to-90 percent charge test by two minutes. During the test, the Ioniq achieved a peak charge rate of 260 kilowatts, averaged 140 kilowatts, and added 72.5 kilowatts to the battery in that span. Adding 150 miles worth of range is quicker now too, with the new model managing that feat in just 16 minutes.2022 Hyundai Ioniq 5Marc Urbano - Car and DriverBoth the 2022 car and the new model wore a set of 255/45R-20 Michelin Primacy Tour all-season tires, so that wasn't a factor that could've affected the range test. We also account for differences in weather, though with both tests occurring on similarly temperate summer days (within one degree of ambient temperature of each other), weather shouldn't have skewed the results either.The improvements to the Ioniq 5's range and charging are sizable enough that if you're in the market for a used model, it could be worth confirming which battery is installed. They're also evidence of the rapidly evolving EV market and a sign of how quickly automakers are improving their hardware. The Ioniq 5's improved range and charging times only make an already-impressive EV even more desirable.➡️ Skip the lot.
