How the WLTP cycle affects the autonomy of EVs

The entry into force of the new WLTP cycle has caused a general decline in the autonomy figures of electric cars.

On September 1st the law came into force new WLTP homologation regulations, a cycle that will facilitate some Much more realistic consumption and emissions figuresThe tests carried out for the WLTP homologation cycle are longer and more reliable than those of the old and more permissible NEDC cycle. electric cars they will also be seen affected by this change which will have a direct impact on its autonomy figures, one of the key elements when purchasing an electric car.

What is the WLTP cycle and how does it work?

The new WLTP homologation cycle carries out Real traffic testing, something that did not happen with the old NEDC cycle. The new homologation tests cars at low, medium and high speeds, that is, for the first time it takes into account the acceleration, braking and stopping phases, something that has an impact on much more real consumption. The Consumption figures will be higher than before, which does not mean that cars will consume more, they will consume exactly the same. The figures will be higher simply because consumption will be extracted through a much stricter process than until now.

In addition, the new WLTP cycle requires homologation of each variant of a model for its equipmentFor example, if we install larger rims than the standard ones, consumption will be affected, which means that the car must be homologated differently.

How will the new WLTP cycle affect electric cars?

The WLTP cycle will not affect electric cars at the tax level. EVs do not emit C02 so will continue to be exempt from paying the registration tax. However, the new homologation regulations Yes, it will affect EV consumption, and therefore their autonomy, one of the factors that most influences the sale of electric cars.

Electric cars will continue to offer the same batteries and their real autonomy will not be conditioned by the new WLTP cycle, but The autonomy figures will be lower than before, because the conditions for calculating it will be more severe.
