While most of us can’t imagine a Mercedes-Benz S-Class running on anything smaller than 6-cylinder engine, the Stuttgart automaker will throw in a 4-cylinder engine in the large luxury sedan next year. Not only will the engine be a 4-cylinder, it will be a 4-cylinder diesel.
The unit, known as the 300 CDI, is a 4-cylinder turbodiesel that produces 201-hp with a peak torque of 384 lb-ft. R&D head Thomas Weber told AutoCar that downsizing the diesel engine for the S-Class was an engineering challenge.
“The issue is NVH [noise, vibration and harshness],” Weber said. “Getting refinement to S-class levels was difficult and we had to change engine mounts and add body stiffness”.
