Changes may have been made to the technical data since the publication date (15.05.2014).
Figures in brackets apply to vehicles with automatic transmission.
More information on official fuel consumption figures and official specific CO2 emissions for new passenger cars is provided in the publication "Leitfaden über den Kraftstoffverbrauch und die CO2-Emissionen neuer Personenkraftwagen" ["Guidelines on fuel consumption and CO2 emissions for new passenger cars"], which is available free of charge from all sales outlets and from Deutsche Automobil Treuhand GmbH.
 Figures for rated output and rated torque in accordance with Directive 80/1269/EEC in the currently applicable version. The figures shown for fuel consumption and CO2 emissions were obtained in accordance with the prescribed measuring process (Regulation [EC] 715/2007 in its currently applicable version). 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. Figures according to Directive 70/156/EEC, version 2000/40/EC Figures for kerb weight according to Directive 92/21/EC, version 95/48/EC (kerb weight with fuel tank 90% full, driver, 68 kg, and luggage, 7 kg) for standard-specification vehicles. Optional extras and accessories will generally increase this figure and reduce the payload accordingly.
