More economical, cleaner, stronger

4-cylinder diesel engines

The 4-cylinder diesel engine proves its up-to-the-minute qualities in both output categories: it impresses with a hefty torque and its immediate response, even in the lower engine speed range. At the same time the diesel engines are modest when it comes to fuel consumption, they are low on emissions, impress with their significantly improved quiet-running characteristics and with their reduced vibrations.

The B 180 CDI BlueEFFICIENCY and B 200 CDI BlueEFFICIENCY models are available for selection.

  • State-of-the-art technology: The fourth-generation common-rail diesel technology boasts an injection pressure that has been increased to 1800 bar, optimised combustion chambers and precise solenoid valve injectors. Improved ignition pressure and a turbocharger with a variable nozzle turbine ensure a high torque in every engine speed range.
  • Impressive figures: The B 180 CDI BlueEFFICIENCY delivers 80 kilowatts with a maximum torque of 250 Newton metres, while the B 200 CDI BlueEFFICIENCY achieves 100 kilowatts at 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. All diesel engines have the ECO start/stop function and meet the requirements of the Euro 5 emissions class.
  • High output figures, low consumption and emissions: the current engine generation features impressive output and high torque while also achieving lower fuel consumption and reduced CO2 emissions.
