However, no mention was made of the S-class receiving a four-banger. Called the 300 CDI, the new model is expected to be powered by the E250 CDI's 201-horsepower turbodiesel engine ( left) , which generates 384 pound-feet of torque. Weber said that downsizing the S-class diesel proved to be an engineering challenge, due to the NVH (noise, vibration and harshness) issues. Customers don't accept much NVH in Mercedes' top-of-the-line automobiles. Mercedes engineers met the challenge by changing engine mounts and adding body stiffness, Weber said. Daimler decision to put a four-cylinder engine in Mercedes' flagship sedan offers further evidence that the trend for downsizing powertrains includes heavy, premium passenger cars.
