4-cylinder diesel engines

The direct-injection 4-cylinder diesel engines deliver adequate power reserves and efficient propulsion. Available in three power bands, they demonstrate appropriately contemporary qualities: they impress with hefty torque and an immediate response, even in the lower engine speed range.

The A 180 CDI BlueEFFICIENCY, A 180 CDI BlueEFFICIENCY (7G-DCT), A 200 CDI BlueEFFICIENCY and A 220 CDI BlueEFFICIENCY models are available for selection.

  • State-of-the-art technology: The fourth generation common rail diesel technology impresses with injection pressure increased up to 1800 bar (A 180 CDI BlueEFFICIENCY: 1600 bar), optimised combustion chambers and precise solenoid valve injectors (A 180 CDI BlueEFFICIENCY: piezo injectors). Improved ignition pressure and a turbocharger with a variable nozzle turbine ensure a high torque in every engine speed range.
  • Impressive figures: The A 180 CDI BlueEFFICIENCY (7G-DCT) delivers 80 kilowatts with a maximum torque of 250 Newton metres. The performance-enhanced A 200 CDI BlueEFFICIENCY, which likewise has a displacement of 1.8 litres, even generates 100 kilowatts with a maximum torque of 300 Newton metres.
  • Clean technology: Measures such as tyres with low rolling resistance, intelligently controlled ancillaries and optimised aerodynamics all help to sustainably increase the vehicle's efficiency. The A 220 CDI BlueEFFICIENCY already complies with the requirements of the Euro 6 emisisons standard.
  • Environmentally safe: The standard ECO start/stop function helps to ensure that the engine is temporarily switched off in stationary traffic, thereby saving fuel. In addition, the ECO display in the instrument cluster provides information about how efficient the driver's driving style is, inspiring them to modify their behaviour and thereby reducing fuel consumption.

[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
