Radius Law launches WLTP advisory service

What is WLTP

The Worldwide Harmonised Light Vehicle Test Procedure (WLTP) is a new global test to measure the level of air pollutants, CO2 emissions and energy consumption in cars and vans. It replaces the ‘New’ European Driving Cycle (NEDC) test that has been used for over 20 years.

WLTP has more dynamic and robust testing procedures designed to better reflect real-world driving conditions and produce much more accurate and realistic results.

The challenges

The switch from NEDC to WLTP and RDE is presenting many challenges in the Auto Sector and we have already seen announcements from some manufacturers to expect production delays as a result.

There are plenty of other challenges too:

  • confusion over the rules – not a big surprise as the WLTP Regulation itself is 600 pages+ and that only gives part of the picture;
  • information on what the consumer needs to know is sparse with no official guidance yet released – this is already negatively affecting consumers as, inevitably, inconsistent practices of providing information have started to appear;
  • taxation, we are told, should not change (at least until April 2020) – but will soon be based on an NEDC CO2 equivalent value using the CO2MPAS tool and there are reports that it is producing a higher than expected CO2 - potentially putting the same vehicle in two different tax bands depending on when it is purchased

Time-line of key changes*

  • September 2018 – all new cars must be certified according to the WLTP test procedure – but there will be some limited exceptions for unsold stock;
  • January 2019 – consumer information to show WLTP fuel and electricity consumption values plus electric ranges. The NEDC CO2 emission value will continue to be presented, rather than the WLTP CO2.
  • April 2020 – consumer information to switch to WLTP CO2
  • April 2020 - taxation will switch to adopting the WLTP CO2

* Van time-line is different.

These are challenges that impact the whole industry from manufacturers, to retailers, to leasing companies and suppliers.  The advice needed is the same and we believe that working collaboratively will bring consumer benefits particularly with the presentation of consumer information.

To this end we would like to establish a WLTP working group.  The working group members will have access to:

  • bi-monthly meetings from September 2018 to May 2020;
  • results/ guidance on detailed research points highlighted by group members (each meeting we will agree up to 5 detailed research points).
  • We will set a meeting agenda – but will make this reflective of the information that you want to know about - so we welcome you sending us agenda items of interest to you.

Whether you are a member of the WLTP working group or not -we’d be pleased to separately provide tailored WLTP guidance for your business.


  • The subscription costs for the WLTP working group are £300 per company per month – to May 2020. This permits 1 person from each company to attend the bi-monthly meetings (additional attendees at a reduced cost);
  • Alternatively, companies may subscribe for 1 month at a time for £500 per month.
