Powerful, efficient and clean: the latest Mercedes-Benz diesel technology in the new CLA. The engine impresses by delivering high pulling power

The 4-cylinder in-line diesel engine with common rail direct injection gives our customers the freedom to explore places around them without worrying about the running costs.


The highlights of the 4-cylinder diesel engine.

The 4-cylinder diesel engine demonstrate hallmark Mercedes qualities: they are modest when it comes to fuel consumption, are low on emissions and impress with their significantly improved quiet-running characteristics and their reduced vibrations.


In order to keep the engine weight as low as possible, the engine is fitted with a crankshaft with four counterweights and a crankcase bearing with individual bearing caps.


The new CLA 200 d has a power output of 100 kW (136 hp) and maximum torque of 300 Nm. As the fourth generation of common-rail diesel technology the engine boast an injection pressure increased to 1800 bar, optimised combustion chambers plus precise solenoid injectors. The high ignition pressure and a turbocharger with a variable nozzle turbine ensure an effortlessly superior torque curve and corresponding pulling power in every engine speed range.


    Further efficiency measures: The diesel drive systems are equipped with the ECO start/stop function which switches off the engine temporarily when the vehicle is stationary. Even greater driving efficiency can be achieved with the help of the standard-fit ECO display which indicates how economically the vehicle is being driven at any given moment. This information can be used to help the driver adopt a driving style which provides for optimum fuel consumption in the current driving situation.
