Diesel engines - driving pleasure through efficiency

Maximum power and smoothness of operation with minimal consumption.

The diesel engines for the E-Class Coupé combine qualities that were previously considered incompatible: Maximum tractive power and smooth operation. At the same time, fuel consumption has never been so low – thanks to innovative BlueEFFICIENCY technology, such as for instance the standard ECO start/stop function.

4-cylinder diesel engines

An exceptional result in terms of agility, smoothness of operation, and consumption and emission figures has been achieved by the Mercedes-Benz engineers with the new-concept 4-cylinder diesel powerplant with two output levels. The engines are significantly more powerful, but at the same time more frugal and cleaner than their respective predecessor models.

Technologies from the BlueEFFICIENCY package were taken for each model in order to achieve the greatest possible degree of environmental friendliness.

You can choose between the E 220 CDI BlueEFFICIENCY and E 250 CDI BlueEFFICIENCY:

  • Up to 23 percent lower fuel consumption and CO2 emissions than similar models from the previous generation: BlueEFFICIENCY technology for every model.
  • Output increased by 20 percent, 25 percent higher torque: thanks to the use of the further enhanced common-rail injection systems with up to 2000 bar of injection pressure, highly precise piezo injectors which allow for a particularly fast and fine metering of the quantity of fuel injected, plus a new turbocharging design.
  • Motivates to save on energy: the ECO display in the instrument cluster gives information on the efficiency of the driver’s manner of driving, thereby motivating the driver to modify his driving style so as to reduce fuel consumption.
  • Improved cold-running behaviour: newly-developed ceramic fast glow plugs
  • Comfort as standard: two Lanchester balancer shafts working to counteract vibrations ensure a smoother ride and a very high level of ride comfort.
6-cylinder diesel engines

Impressive features of the E 350 CDI BlueEFFICIENCY 6-cylinder diesel engine include smooth running characteristics, reduced consumption and low emission figures.

  • Ready to sprint: The maximum torque of 620 Newton metres is available even at an engine speed range of between 1600 and 2400 rpm.
  • Protects the environment: The engine meets the requirements of the Euro 5 emissions class. A particulate filter also reduces particulate emissions.
  • Motivates to save on energy: the ECO display in the instrument cluster gives information on the efficiency of the driver’s manner of driving, thereby motivating the driver to modify his driving style so as to reduce fuel consumption.
  • Precise response: Piezo injectors allow for finely metered fuel injection.
