 Figures for rated output and rated torque pursuant to Directive 715/2007/EEC in the currently applicable version.
 The values provided are the "measured NEDC CO2 values" in accordance with art. 2 nr. 2 implementing regulation (EU) 2017/1153, which were determined in line with Annex XII of Directive (EC) no. 692/2008. The fuel consumption values were calculated based on these values. Due to the legal changes to the relevant test process, higher values can be entered into the certificate of conformity relevant to the vehicle registration and, if necessary, vehicle tax. The figures are not based on an individual vehicle and do not constitute part of the product offer; they are provided solely for purposes of comparison between different vehicle models. The values vary depending on the selected special equipment.
