EV Highway Range Calculator
The official range assumes slow city driving. On the highway, aerodynamics dominate. See the real range of your EV at 100, 110, 120 and 130 km/h.

Highway efficiency tips
- Keep it at 100-110 km/h. The biggest range win available on a trip.
- Use adaptive cruise control. Steady speed beats constant micro-adjustments.
- Check tire pressure. Under-inflated tires cost 3-5% range.
- Precondition while plugged in. Heats the cabin before you drive, not on battery.

Frequently asked questions
Why does EV range drop on the highway?
Aerodynamic drag grows with the square of speed. At 120 km/h an EV uses roughly 30-40% more energy than at 80 km/h, so highway range is typically 20-30% below the WLTP mixed figure.
What is the best highway speed for an EV?
For the best balance of range and practicality, 100-110 km/h is the sweet spot. Dropping from 130 to 110 km/h can recover 15-20% of range while only adding ~10 minutes per 200 km.
How much range do I lose at 130 km/h?
At a constant 130 km/h, expect roughly 45-55% less range than the official WLTP figure for many EVs — the combined cycle assumes ~47 km/h average, which is nothing like highway driving.
Do heat pumps help on the highway?
A heat pump helps mostly in cold weather when cabin heating matters. On a mild highway run it saves little — speed and aerodynamics dominate, not climate.
