Diesel engines – powerfully efficient

Model Cylinder arrangement/number Displacement (cc) Rated output (kW [hp] at rpm)[1] Top speed (km/h) Fuel consumption combined (l/100km)[2] CO2 emissions combined (g/km)[2]
E 220 d R4 1950 143 [194]/3800 237 4.9–4.3 126–113

Always superior, always restrained

The diesel engine of the new E-Class Cabriolet combines luxuriant power reserves and cultivated smooth running with maximum efficiency. This means you always travel fuel-efficiently and can at the same time enjoy the sporty driving dynamics of your new E-Class Cabriolet.

4-cylinder in-line diesel engine

The new E-Class Cabriolet is powered by a new intelligent engine generation. The 4-cylinder diesel engine in the E 220 d with an output of 143 kW[1] (194 hp) and a maximum torque level of 400 [1] newton metres makes you experience efficiency in an entirely new manner. In addition, consistent lightweight design makes low consumption values possible.

6-cylinder diesel engine

Take advantage of the efficiency of cutting-edge diesel technology and enjoy the drive comfort of a 6-cylinder vehicle. The new E 350 d 4MATIC combines high performance with cultivated travelling.

Details on the engine technology

The sounds made by the 4-cylinder in-line diesel engine have been audibly optimised through a whole package of measures. The engine block has been stiffened by means of an extremely rigid bed-plate construction and this, for example, minimises the engine vibrations.

What's more, complex insulation measures have been deployed to reduce the sound of the engine in the vehicle interior and surrounds. Thanks to these measures the engine sounds powerful and dynamic inside the vehicle, and hardly like a diesel engine at all. And not just to the vehicle occupants: for the exterior noise has been reduced and the engine tuned to sound a lot smoother.

Details on efficiency

One reason for the pronounced economy of the new engine generation is the systematic optimisation of friction points. An example of this is the pioneering combination of steel pistons with a full-aluminium crankcase with NANOSLIDE cylinder wall coating. In addition, a new oil pump reduces fuel consumption and CO2 emissions.

[1] Figures for rated output and rated torque pursuant to Directive 595/2009/EEC in the currently applicable version.[2] 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. The values vary depending on wheels/tyres.
