Looking for a Vehicle Valuation or hpi check?

cap hpi sets out WLTP data integration.


The UK’s largest provider of vehicle data, cap hpi, has moved to integrate the additional data needed to handle the expected changes that will come from the new WLTP and RDE emissions tests.

The additional information will be available in the company’s New Vehicle Data set (NVD) over the coming months.

The EU legislation aims to provide customers with a more detailed view of how a vehicle performs concerning mpg and CO2.  The previous NEDC test cycle does not take optional equipment into account and doesn’t offer an accurate representation of driving styles which affect the emissions produced by a vehicle.

The new Worldwide Harmonised Light Vehicle Test Procedure (WLTP) takes options into account on a vehicle as it’s acknowledged certain items will affect the aerodynamics, weight and rolling resistance.

The Department for Transport is currently undertaking a consultation piece with the industry with the output expected in June.

Beth Davies, product manager at cap hpi, said: “We are planning for all scenarios and our solution includes all the data items that could be required from the OEMs and necessary for a customer who receives and use the data.

“We have listened to our customers and will be making changes to our NVD dictionary to show which values are NEDC and which are NEDC correlated.”

WLTP was implemented for all new engines homologated (tested) from 1st Sept 2017. Manufacturers are expected to re-homologate all current vehicles in their product suites in the UK by 31st August 2018.

There will be a migration period to allow all links in the NVD chain to make changes to their systems to take the more detailed information generated by WLTP.

It is important to remember that the NEDC correlated value does not include optional equipment. WLTP in its true form will come into circulation from Sept 2018, but there will be no fiscal impact to tax until April 2020.

Customers of cap hpi will be able to see under which test the vehicle derivative has passed. The data solution is future-proofed by naming the test cycle being used by each derivative. It is likely further changes to emissions measurement will appear in the coming years.

Davies said: “While the NVD file amendments are one component of the work necessary to deliver the changes, we are also working with all the manufacturers on the solution to provide options emissions data in readiness for the change of legislation.

“Our solution will cater for individually configured vehicles as the end customer will need to be provided with a true reflection of the vehicle’s emissions at point of sale. This will help them to make a more informed decision. We will build an API for our customers to link into, this will enable them to send quotes to first, be validated, and then to receive the relevant CO2 and MPG values for the configured vehicle.”
