Testing procedure changes

Like NEDC (New European Driving Cycle), WLTP is a laboratory based testing procedure. There are some key differences with WLTP to provide consumption and emissions values that better reflect real world performance. The advantage of laboratory tests is that they are carried out in controlled conditions. This enables customers to gain a true comparative view between vehicle models.
