The EV Route

Range

What range will you actually get?

The official figure is a laboratory result at a moderate temperature. Two things break it on a real journey: sustained speed and cold.

Why speed costs so much

At urban speeds most of your energy goes into accelerating mass, and regenerative braking gets a good share of it back. On a motorway almost none of it does — you are pushing air out of the way continuously, and that cost scales with the square of your speed while the power required scales with the cube.

The practical consequence is that the difference between 110 and 130 km/h is much larger than the 18% speed difference suggests. On a long drive, dropping 20 km/h frequently saves a charging stop, which saves more time than it costs.

Speed and consumption

The winter penalty

Two effects compound. The cabin needs heating, and in a car with resistive heating that draws directly from the traction battery. And the pack itself accepts and delivers energy less readily when cold, which also slows rapid charging. Studies measuring ambient temperature effects on consumption quantify the combined result [1].

Common questions

How much range do I lose in winter?
Enough to change a journey plan. Measurement studies confirm a substantial temperature effect [1]; the size depends on the car, the heating system and how cold it is.
Should I slow down?
On a long motorway run, often yes. The time lost driving slower is frequently less than the time saved by skipping a stop.
Does a roof box matter?
A great deal. It increases frontal area and drag, which is exactly what costs you at speed.
Why is my consumption worse than reviews?
Reviews are often measured on mixed routes in mild weather. Sustained motorway speed and cold are the two variables that separate a review figure from yours.
