Real Range Calculator

What is WLTP range?

WLTP (Worldwide Harmonised Light Vehicle Test Procedure) is the official lab test used so every EV can be compared under identical conditions. Each car follows the same circuit at mild temperatures, with:

• No heating or air‑conditioning running
• Only brief high‑speed sections

If you drive in similar conditions—urban speeds (50–80 km/h) and mild weather (around 23 °C) – you can expect to match the WLTP figure.

How to use this calculator

Adjust driving style to your typical usage.

• If all your driving, every day was on a state highway (or a motorway that wasn’t stuck in a traffic jam) — then you’d shift the slider all the way to the right.
• If all your driving was down to the shops, the school run, and some cruising on an 80 km/h road – then you’d shift the slider to the left.

High speeds really do increase energy consumption in an EV.

What about hills? Generally what goes up must come down, and EVs are exceptionally good at reharvesting energy while going down a hill. This is something you can only figure out through experience.

Adjust for temperature

While all cars use more energy (petrol / diesel / electricity) when it's cold, battery EVs can be significantly affected by colder temperatures.

Also, the WLTP test is carried out at 23 degrees, so any temperature colder than that tends to lower vehicle range.

Calculator limitations

1. The algorithm does not take into account things like heat pumps and aerodynamic differences. It’s a general formula that applies the usable battery capacity and WLTP range and consumption values against a model from real-world tests.
2. If your EV has a heat pump – it will probably get a longer range in colder temperatures.
3. If your EV has impressive aerodynamics, it might do slightly better at higher speeds.
