Cap HPI says it will be ready for the introduction of motoring taxes based on the emissions test in April 2020. 

Gaps in vehicle CO2 data from the new Worldwide Harmonised Light Vehicle Procedure (WLTP) test held by leasing companies have been causing a headache for fleets.

Many manufacturers, including Mercedes-Benz, BMW and Volkswagen Group, have published CO2 values derived from the new test, but some others have been slow to reveal their full results.

Cap HPI is now reporting it has a 90% fill-rate across all manufacturers and says its WLTP Emissions Service API can offer dealers and fleets a solution to manage dynamically configured vehicles, and content collation of new, static values within new vehicle data (NVD).

WLTP comes into force in the UK on April 1 for VED and April 6 for benefit-in-kind (BIK) tax. Vehicles registered after this date will be taxed using the new WLTP CO2 emissions values.

The values will relate to the specific configuration of an individual vehicle, taking optional equipment fitted to the vehicle into account for the first time.

The requirement for the supply and consumption of the new values from manufacturers has impacted the whole industry, with manufacturers and downstream customers having to make significant changes to systems and business processes.

Beth Davies, product manager at Cap HPI, said: “Our data contains static WLTP values; currently there is a 90% fill level of WLTP CO2 across all brands, and following discussions with manufacturers, we will continue to increase this over the coming weeks.

“Data for both NEDC and WLTP values are available, and support is on-hand to advise on using the new vehicle data.

“We have also developed a real-time solution for customers that gives them confidence in the data to navigate the transition.

“We understand these changes represent a significant shift for the industry and getting it wrong can prove costly. That’s why we’ve focused considerable resources on collecting, collating and providing this data ahead of the legislation changes to ensure a smooth transition for our customers.

“The requirement for the supply and consumption of the new values from manufacturers has impacted the whole industry, and Cap HPI has developed a dual solution to support customers through the change.”

If options are added to a derivative, then the WLTP CO2 emissions values will change. It can have a significant impact on its tax band.

The new WLTP Emissions Service API for dynamically configured vehicles handles these scenarios.

Davies concluded: “We believe a dual solution provides the best support to our customers through the change to the new values.

“The team is working with customers to implement a WLTP Emissions Service API for dynamically configured vehicles, and content collation of new, static values within NVD.”
