GMC Sierra EV 20-mod battery

Estimates of actual range. The values given here are BEVDB estimates calculated from EPA data and usable battery capacity, based on the BEVDB model. The BEVDB real-range card uses four fixed reference scenarios: City (Mild), Highway (Mild), City (Cold), and Highway (Cold). Mild means +20°C (70°F) without intensive climate-control use; cold means -10°C (14°F) with cabin heating. City speed is 50 km/h (30 mph), and highway speed is 110 km/h (70 mph). These figures are not official test results. Actual range will vary depending on speed, temperature, road conditions, road profile, load, tires, and driving style.

BEVDB model

BEVDB estimates use EPA-rated (or derived) consumption and usable battery capacity to model city/highway ranges; the combined value is a weighted mix of city/highway and mild/cold scenarios. See the methodology and data sources for inputs, official source boundaries, fallback rules, and versioning.
