Reference data

EV efficiency, temperature, and speed — the numbers behind every estimate.

Most efficient EVs by real-world consumption

The 25 most efficient electric vehicles in our catalog, ranked by real-world Wh/km. Real-world figures are calibrated from manufacturer WLTP via the EV-Database community correction factor (~1.18× WLTP on average).

Temperature impact on EV energy consumption

Battery efficiency drops in cold weather and HVAC load rises in heat. EVStrada interpolates between the points below; the rightmost column shows how many extra kWh a typical 16 kWh/100km EV uses on a 100 km drive relative to a 20 °C baseline.

Ambient temperatureMultiplier vs 20 °CRange changeExtra kWh / 100 km
-20 °C×1.40−29%+6.4 kWh
-10 °C×1.32−24%+5.1 kWh
0 °C×1.22−18%+3.5 kWh
10 °C×1.10−9%+1.6 kWh
20 °C×1.00baseline
30 °C×1.06−6%+1.0 kWh
40 °C×1.12−11%+1.9 kWh

Speed impact on EV energy consumption

Aerodynamic drag rises with the square of speed. EVStrada multiplies the per-segment baseline consumption by the factor below — the gap between 100 and 130 km/h is the single biggest variable on a long motorway trip.

Average speedMultiplier vs 90 km/hExtra kWh / 100 km
50 km/h×0.82-2.9 kWh
80 km/h×0.95-0.8 kWh
100 km/h×1.08+1.3 kWh
120 km/h×1.25+4.0 kWh
130 km/h×1.35+5.6 kWh
