Range remains the first question asked before buying an electric car, well ahead of charging costs. It is also where the gap between the spec sheet and reality surprises buyers the most: a saloon rated at 500 km almost never shows 500 km on the dashboard. This article covers what the advertised figures are really worth, what melts the kilometres away, and how to pick a range that matches real journeys rather than worries.

Advertised vs real range: where the gap comes from

The range figures quoted by manufacturers come from the WLTP homologation cycle, a laboratory protocol shared across Europe. It makes model-to-model comparison possible, but it runs at an average speed of 46 km/h, without heating or air conditioning, on a driving profile far gentler than any real journey.

In normal use, subtract 20 to 30% from the WLTP figure. A compact rated at 420 km therefore covers 300 to 340 km in mixed driving, and noticeably less on a winter motorway. This gap is not a hidden flaw: it is systematic, well documented, and worth building into any needs assessment from day one.

The five factors that melt kilometres away

Speed comes first. Air resistance grows with the square of speed: going from 110 to 130 km/h pushes consumption up by about 25%. That is why an electric car that feels tireless in town can disappoint on the motorway.

Cold comes next. Below 5°C, battery chemistry loses efficiency and the heater draws directly from the pack: winter routinely removes 20 to 30% of range. Models fitted with a heat pump limit the damage considerably, a spec worth checking before buying.

Then come terrain (a long climb consumes heavily, even if the descent regenerates part of it), payload and tyre condition. A tyre under-inflated by 0.5 bar is enough to raise consumption measurably, electric or not.

Which models go the distance

The 2026 market splits into three families. City cars (Renault 5 E-Tech, Citroën ë-C3, Fiat 500e) offer 250 to 400 km WLTP, ample for urban and suburban use. Compacts and family saloons (Tesla Model 3, Renault Scénic E-Tech, Peugeot e-3008) sit between 450 and 700 km depending on the battery. At the top end, a few grand tourers now exceed 700 km WLTP, at prices that still reserve them for wealthy buyers.

To compare two close rivals, the duel between the BYD Seal and the Tesla Model 3 shows the right way to read the numbers: beyond the WLTP figure, real consumption per 100 km and charging speed make the daily difference. The same reasoning applies to company cars, where range defines professional usability.

How much range do you actually need?

The average French driver covers less than 50 km a day. With a real-world range of 250 to 300 km, a week of commuting fits on a single charge, done at home or at the office. Buying 700 km of range for that profile means paying for a big battery that only earns its keep a few weekends a year.

The question changes for high-mileage drivers and motorway regulars. There, two figures matter more than headline range: consumption at 130 km/h and the 10-to-80% charging time on a fast charger. A car that recovers 300 km in 20 minutes makes long trips calmer than a rival with a bigger battery but slower charging.

Six habits that add kilometres back

  • Anticipate rather than brake: smooth driving maximises regeneration on lift-off.
  • Slow down on the motorway: driving at 120 rather than 130 km/h extends range very noticeably.
  • Pre-heat the car while charging: the cabin warms up on grid power, not on the battery.
  • Use heated seats rather than cabin heating; they draw far less power.
  • Check tyre pressure monthly, and aim for the higher recommended value.
  • Remove roof boxes and bike racks when unused: aerodynamics weigh heavily at cruising speed.

Electric mobility goes beyond the car, too: for short urban trips, an electric scooter or electric bike complements an equipped household well, and the electric motorcycle market is progressing fast.

And in five years?

Batteries gain roughly 5 to 8% energy density per year, and the first solid-state cells announced for the end of the decade promise a further jump. In other words, range anxiety increasingly belongs to the past: the real question for a 2026 buyer is no longer “how many kilometres”, but “what charging, where, and at what price”.
