The 2026 GMC Sierra EV 20-mod battery, 19kW 15-mode charger is rated at 620 km (385 mi) on the EPA test cycle. That's a laboratory figure — in mixed real-world driving expect roughly 589 km, less in winter or at sustained highway speed. On a road-network range map that's rarely a neat circle — terrain, highways and coastlines shape where one charge can actually take you. For a trip out and back home without charging, plan around an effective radius of about 310 km.
