* According to Regulations (EC) No 715/2007 and (EC) No 692/2008 (in the version currently applicable). The figures do not refer to a specific vehicle and are not part of a specific offer but serve purely for comparing various types of vehicles.
** The lower value represents the lowest measurement taken from the four phases of the WLTP cycle, using the fuel consumption of a vehicle with the most economical vehicle equipment of the relative engine and transmission combination. The upper value represents the highest measurement of the four WLTP cycle phases, taken from the corre-sponding fuel consumption of the most fuel-intensive equipped vehicle.
The daily fuel consumption of a vehicle depends very much on the individual usage profile and where it is being driven: city traffic, country roads or motorways. These differences are better accounted for by the WLTP driving cycle. Instead of calculating only the values "urban, extra-urban and combined" (as stipulated by Regulations (EC) No. 715/2007 and 692/2008,) on the basis of a more theoretical driving profile, WLTP provides four individual values for different predetermined travel profiles (low, medium, high, and extra-high) that are based on statistical surveys and the analysis of user profiles and averages. In addition, the WLTP driving cycle is much more dynamic than the NEDC and reflects higher accelerations, a higher average speed and a higher maximum speed.
The values released for the Opel Astra from June 2016 Opel show a range that can be explained as follows: The lower value is the lowest value from the four phases of the WLTP, driven with the version of the Opel Astra with the lowest consumption values for the specified engine/transmission combination. The upper value represents the highest value from the four phases of WLTP cycle, driven in the version of the Opel Astra with the highest consumption values for the respective specified engine/transmission combination. The values obtained provide a good overview and a useful indication of the expected daily consumption.
Please note, that the values based on the WLTP driving cycle are determined by using a standardized, predefined driving cycle on a test rig.
