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 model

Combined real range (estimate)	310 miles
Combined Energy Use (estimate)	54.5 kWh/100 mi

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.
