EV Range Calculator
Physics-grounded calculator built on Gulf real-world road tests: WLTP assumes 23 °C and modest speeds — this tool gives you actual range at 50 °C, your real cruising speed, your pack chemistry, and the SoC window real owners use.

How does the calculator work? Full physics breakdown
Real range = (WLTP range) × (1 − aero loss) × (1 − thermal loss) × (1 − A/C loss) × (1 − chemistry loss) × (1 − SoC window loss) × (1 + regen gain) × (1 − accessory loss).
- Aero drag: Drag scales with speed². WLTP assumes ~46 km/h avg; at 120 km/h drag loss reaches 22–28%.
- Battery thermal: Cell efficiency drops below 0°C and above 35°C. At 50°C losses are 8–14% depending on the cooling system.
- A/C draw: Draws 1.5–4 kW depending on cabin-vs-target ΔT. Heat soak adds ~3% extra for initial cooling.
- Chemistry: LFP is more thermally resilient but loses ~5% more capacity at high temperatures than NMC.
- SoC window: Most owners cycle 90→15% in practice, which is only 75% of nameplate capacity.
- Regen: City stop-go driving recovers 12–22% of kinetic energy — a positive gain factor.

EV range FAQ for the Gulf
Why doesn't WLTP reflect Saudi reality?
WLTP tests at 46 km/h avg speed and 23°C — mild conditions. Gulf summer hits 50°C and our actual highway speeds are 120-140 km/h. Both massively increase EV energy use.
Which EV is best suited to Gulf summer?
EVs with active battery cooling and heat pumps — Tesla Model Y, Hyundai Ioniq 5, Kia EV6, Mercedes EQS, BMW iX. They lose only 12-18% at 50°C, while passively cooled EVs lose 25-35%.
LFP or NMC for Gulf use?
LFP lasts longer and has lower fire risk, but loses ~5% more efficiency at 50°C than NMC. For daily Gulf driving NMC gives better real range; LFP gives more years of service.
How much does monthly EV charging cost?
At 1,500 km/month and 22 kWh/100km (with Gulf A/C), you need 330 kWh. Saudi home electricity ~0.18 SAR/kWh = ~60 SAR/month. Public DC fast charging (0.85 SAR/kWh) is closer to 280 SAR.
Can I drive Riyadh → Jeddah on an EV?
Yes — 950 km, with TAQAT and EVIQ networks along the route. Plan 2-3 stops (45-60 min each) if your real range is 350-400 km. Use charging apps to plan ahead.
When does battery degradation get critical?
Above 45°C with frequent DC fast-charging accelerates degradation 15-20% over 3 years. EVs with active cooling resist this better. Charge slowly (home AC) whenever possible in summer.
