Real-world EV range explained

Real range is usually below the advertised figure, because advertised range comes from a standard lab test. Payload, speed, weather and hills all change the result.

What the WLTP test does

Most advertised range figures use the WLTP lab test. For light commercial vehicles, it carries only part of the maximum payload, and it runs at a lower average speed than highway driving.

What changes real range

• Payload: more weight takes more energy, especially in stop-start driving.
• Speed: air resistance grows quickly at highway speed, and vans feel this more than cars.
• Heat and cold: air conditioning, heating and battery temperature all use energy.
• Hills and towing: towing can reduce range sharply.
• Battery age: usable capacity falls slowly over time.

How we estimate it

Our range figures with half and full payload start from the WLTP figure. We work out the change in mass from the GVM and payload, then allow for real driving. They are estimates, not maker figures, and each one is labelled.

See the estimate on any electric van page, or use the calculators.
