The Hyundai Ioniq 5 N is one of the most unique electric vehicles available today, and it may just be most fun EV on sale. However, it’s driving range isn’t its strongest selling point, with an EPA combined range rating of only 221 miles.
We recently charged one up to 100 percent and headed out onto the highway to find out how far it would go at a constant 70 miles per hour in the InsideEVs 70 mph highway range test.

The Ioniq 5 N is a wonderfully engineered high-performance EV. Hyundai did an amazing job incorporating artificial gears and exhaust noise into the vehicle, and it works much better than I expected it would. I’m not usually one for fake engine sounds, as I really appreciate the quiet hum of the electric motors and usually turn off the fake sounds that some EVs have. But the 5 N was different, it all really worked for me. It felt real.
However, I couldn’t really enjoy any of that while I was doing the 70 mph range test, which is perhaps the least fun you could have with the 5 N. But that was the task at hand, so like all of the range tests we do, I charged the vehicle up to 100% on a DC fast charger to heat up the battery as much as possible, made sure the tire pressure was set to the manufacturer’s recommendation, put the vehicle in its most efficient driving mode and set the climate control to 69°F with the lowest fan setting.
The 2025 Hyundai Ioniq 5 N has a combined EPA range rating of 221 miles. That’s 39 miles less than the AWD Ioniq 5 Long Range (260 miles) and 82 miles less than the RWD Long Range version (303 miles).
However, since this is a highway range test, I looked up the EPA documents and found that the Ioniq 5 N’s highway rating is 202 miles, so I was personally expecting to finish up somewhere between that and its combined EPA range rating. The EPA test isn’t a constant-speed test, and it’s done at lower speeds than 70 mph,. It’s not a perfect comparison, but it’s all we have to compare our range test results to.

Hyundai Ioniq 5 EPA range ratings
In exchange for the range left on the table, the Ioniq 5 N has a combined power output of 641 hp and 568 lb-ft of torque with its “N Grin Boost” feature activated, which provides a temporary 10-second power boost. Without the N Grin boost, the combined power is around 601 hp. The massive 275/35 ZR21 Pirelli P-Zero tires also account for some of the range loss.
On our test day, the weather was very accommodating. The temperature was unusually warm; over 80°F and with very little wind. I squeezed every bit of energy out of the Ioniq 5 N’s 84 kWh battery pack and ended up driving it about 7 miles after the state of charge and the estimated remaining miles read zero.
However, much of that was due to my mistake of allowing the navigation system to lead me to the wrong Walmart. I had intended to go to a different Walmart about 6 miles away because that one has an Electrify America charging station in the parking lot, but I selected the wrong one in the navigation system.

That meant I had to limp at low speeds to the other Walmart in reduced power mode for the final 6 miles. I finished up the test having driven 230 miles, 9 miles more than the combined EPA range rating for the 5 N, and 28 miles farther than its highway range rating. But the final 6 miles were driven at low speeds, so we can’t really count them in the 70 mph range test.
I think I was at about 224 miles when I slowed down under 70 mph. The vehicle did have enough left in the patch to go another 6 miles at low speeds, so it probably could have done at least 2 or 3 more at 70 mph. We could safely say the vehicle would have done 226 or 227 miles before it would have shut down if we continued driving at 70 mph until the end.
| Test Segment | Miles Driven | Total Miles | Consumption |
| 100% to 75% | 60 | 60 | 2.7 mi/kWh |
| 75% to 50% | 57 | 117 | 2.7 mi/kWh |
| 50% to 25% | 58 | 175 | 2.8 mi/kWh |
| 25% to 0% | 55 | 230 | 2.8 mi/kWh |
About our 70 mph highway range tests:
We always like to mention that these range tests aren’t perfect. There are variables out of our control, like wind, traffic, topography, and weather. However, we do our best to control what we can and set all the vehicles we test up to the same standards so we can compare them as fairly as possible.
We conduct these 70-mph range tests to provide another data point for potential customers who are looking for as much information on the driving range of a particular EV as possible.
