Figures in brackets apply to vehicles with automatic transmission.

[1] Figures for rated output and rated torque in accordance with Directive 80/1269/EEC in the currently applicable version.[2] 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.[3] 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.
