CONCERNS around supply shortages of new vehicles after 31 August may be unwarranted.

Data experts at cap hpi have advised the re-certification of vehicles under the WLTP’ Second Act’ is an administrative exercise that does not require physical re-testing.

The ‘Second Act’ means all manufacturers must ensure new models are ‘certified’ to show they have passed the more stringent WLTP tests before they can be placed on the market.

Every manufacturer will ensure that every new car is certified under the new type approval before it can be allowed on sale.

Beth Davies, product manager at cap hpi, said: “We have seen widespread reporting of concerns around supply shortages in September but find this is extremely unlikely.

“The WLTP ‘second act’ certification is simply a revision of the existing WLTP testing regime. Vehicles will not be physically tested but instead processed through revised algorithms and confirmed as re-certified.”

The revisions will take into account the introduction of RDE at the type-approval stage, and also the new evaporative emissions test.

This takes into account the technological progress in the control of evaporative emissions from petrol vehicles and adapts that procedure to the WLTP test procedure and introduces new provisions for sealed tanks.

The data company said it has already moved to recognise the new ‘second act’ identifier in its New Vehicle Data. The identifier can be found in the Emissions Test Cycle field and will feed into wider cap hpi products such as Valuation Anywhere and Cap Connect. Any existing vehicles will continue to be shown as ‘NEDC Correlated’.

The changes mean all new vehicles must be certified under the second act test by 31 August to be able to be sold from 1 September 2019.
