Speed is the biggest impact factor on battery range.  When highway driving at 130 km/h, at constant speed, the range of a 100% electric vehicle is almost halved compared to that of the WLTP cycle. Meanwhile, at constant urban driving speeds, the range can be extended beyond the WLTP cycle.

Eco-driving is key to maximizing the autonomy of electric vehicles. Smooth acceleration and gentle use of braking reduces energy consumption, whilst the one-pedal drive function maximizes the regenerative braking effect. Combined, these can help optimize autonomy by 15% - 20%.

Exterior temperatures, plus the heating or air conditioning can affect the potential range by up to 40%, depending on the season and cabin thermal comfort required. Preheating the car when it is still plugged in is very effective to improve autonomy.
