WLTP: The New Standard of Fuel Efficiency

The automotive industry is an ever-evolving beast, with changes occurring in all manner of ways. From major developments in technology to more efficient engines, there’s always new and innovative ways for the industry to progress. One of the latest developments across the industry is the introduction of the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) for fuel efficiency and emissions.

Since September 2018, the WLTP standard has replaced the New European Drive Cycle (NDEC) standard, and has been devised to provide a more accurate assessment of fuel efficiency for petrol, diesel, electric and hybrid vehicles. As a result, you can take a more informed approach to selecting the ideal vehicle for you - meaning you will be able to invest in the new or used Jaguar that matches your demands for efficiency and cleanliness.

Replacing NDEC has been a slow process. First introduced in 1997 when the initial wave of hybrid vehicles became available, the NDEC standards have become outdated and unsuitable for the latest models. The new WLTP tests, however, have been designed to better examine the efficiency of models, increasing testing time from 20 to 30 minutes in duration and incorporating the effect of optional and additional equipment.

With WLTP being more accurate, you may notice that in like-for-like comparisons with NDEC figures, the fuel consumption and CO2 figures will be higher, while electric vehicles will show a range that is lower in value. As this transition continues, you will often be presented with both sets of data, so you can continue to compare and experience the most accurate results possible.

Here at Spirit Jaguar, we’re delighted to be able to detail the most accurate information possible about our Jaguar vehicles. Of course, you can also liaise with a member of the team direct to discuss options, and we’ll be delighted to provide you with all the necessary details to make the best choice possible.
