Real range estimates The values shown here are estimates calculated by BEV-Database using EPA range/efficiency data (where available) and the usable battery capacity of the car. “Mild weather" represents driving in roughly 68-77 °F without heavy use of climate control, while "Cold weather" reflects winter conditions with the cabin heater on (around 14 °F). "Highway" figures assume steady cruising at about 65 mph-70 mph. These figures are not official test results or guarantees. Real-world range will vary depending on speed, temperature, traffic, road profile, payload, tires and driving style.
Reminder: Range and energy consumption figures are estimates. Actual results may vary depending on weather, driving style, terrain, and other conditions.
