Monthly estimated driving range
Select vehicle and weather location
Min and max are the lowest and highest modeled daily ranges observed within each calendar month across 2021–2025—not statistical confidence intervals.
Monthly breakdown
Daily simulated ranges from hourly temperatures, humidity and sunlight (2021–2025); monthly min, mean and max.

Method & assumptions
Speed sensitivity is a first-order aerodynamic proxy, not a vehicle-specific drag model; traffic and wind are excluded.
Show the climate-to-range equation
E₀ = battery_kWh / EPA_range_km; eₜᵣₐ꜀ₜᵢₒₙ = E₀ × driving-mode multiplier. Cooling power (kW) = max(0, 0.18 + 0.115 × (ambient °C − cabin °C) + 0.012 × max(0, RH % − 40)) for ambient above cabin + 2°C; heating power = 0.22 + 0.085 × (17°C − ambient °C) for ambient below 17°C; additional battery thermal management = max(0, ambient − 35°C) × 0.035 kW (or max(0, 10 − ambient) × 0.045 kW in cold conditions). Auxiliary values and thresholds are assumed, illustrative calibration parameters. Range = usable SOC × battery kWh / [eₜᵣₐ꜀ₜᵢₒₙ + (auxiliary kW / average speed)]. A nominal 0.2 kW common auxiliary contribution is included. Calibration against measured Saudi driving telemetry is required before operational use.
