Cap HPI is set to integrate the additional data from new real-world emissions tests into its New Vehicle Data set.

The new tests are part of EU legislation and aim to provide customers with a more detailed view of how a vehicle performs concerning mpg and CO2.

Following demand from customers, the data provider confirmed it will be differentiating between older NEDC figures and newer NEDC correlated figures.

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

NEDC correlated values are derived from WLTP testing but converted back to an NEDC figure and 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.

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.

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.

“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.”
