Figures in brackets apply to vehicles with automatic transmission
 Figures for rated output and rated torque pursuant to Directive 595/2009/EEC in the currently applicable version.
 The figures shown for fuel consumption and CO2 emissions were obtained in accordance with the prescribed measuring methods (section 2 nos. 5, 6, 6a Pkw-EnVKV as amended). 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.
* With 18” AMG alloy wheels (no cost option)
The declared fuel and energy consumption figures are determined by testing under standardised laboratory conditions to comply with ADR 81/02. Real world consumption is influenced by many additional factors such as fuel quality, individual driving style, load, traffic and vehicle condition. The declared consumption figure should only be used for the purpose of comparison amongst vehicles.
