Tested: The 2025 Hyundai Ioniq 5 N 70 MPH Highway Range Test

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.
