GMC Sierra EV 20-mod battery 2026 is a different kind of EV: an AWD electric pickup truck with utility-first packaging and a bigger charging-planning burden. The official EPA range is a useful headline, but the BEVDB mixed estimate of about 360 mi and the 262 mi cold-highway scenario are better planning figures.
In daily use, home charging takes about 9 h 10 min from 0-100%; on trips, the 10-80% DC estimate is about 27 min (est.), which should make highway stops manageable. The practical side is documented with 5 seats, 57.3 cu ft cargo and 8 years / 100,000 miles battery warranty. The main caveat is that cold highway range is much lower than the mixed-weather estimate. Range confidence is high, while specs completeness is mostly complete.

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.
Fast-charging times may use BEVDB estimates when measured 10–80% data is unavailable. Lower-power charger scenarios are estimated from the vehicle's 10–80% charging profile.
Estimated charging times are based on usable battery capacity, charging power and vehicle charging limits. Peak DC power is usually reached only briefly; average 10–80% power is more useful for estimating real charging time. Actual charging speed can vary by charger output, battery temperature, state of charge, weather, software and battery condition.
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.
Reminder: Range and energy consumption figures are estimates. Actual results may vary depending on weather, driving style, terrain, and other conditions.
