Volvo complies with WLTP protocols

Volvo has homologated its entire model range under the new Worldwide Harmonised Light Vehicle Test Procedure (WLTP).

All Volvo petrol, diesel and hybrid models now comply with the stringent ‘Euro 6d-temp’ standard for tailpipe emissions, as part of the firm’s model-year 2019 range update.

The aim of the new WLTP cycle is to ensure published fuel economy and emissions – which all manufacturers legally must publish – offer a more realistic reflection of real-world driving, helping customers to judge better the fuel and emission efficiency of their car.

WLTP is a laboratory test and replaces the New European Driving Cycle (NEDC) that can trace its roots back to the 1980s. Both tests enable customers to make comparisons between different vehicles, but WLTP uses a driving cycle that is more reflective of on-road driving.

The figures Volvo publishes for its models are achieved through the WLTP cycle, then correlated back to an NEDC equivalent for comparison purposes.

‘Volvo welcomed the new WLTP testing methods when they were first announced, as greater transparency in areas such as fuel consumption and emissions helps customers make better informed buying decisions,’ explained Jon Wakefield, Volvo Car UK’s managing director.
