Currently reading: S-class to get four-pot engine
New model is expected to be powered by E250 CDI's 201bhp unit

The current Mercedes S-class will receive an eco boost with the arrival of a four-cylinder diesel version next year.

Called the 300 CDI, the new model is expected to be powered by the E250 CDI’s 201bhp turbodiesel, pushing out 384lb ft of torque.

Mercedes' R&D boss Thomas Weber admitted that downsizing the S-class diesel was an engineering challenge.

"The issue is NVH [noise, vibration and harshness]," he said. "Getting refinement to S-class levels was difficult and we had to change engine mounts and add body stiffness".

Logical step. It will be well excecuted. Can JLR get the 2.2 four cyl engine (if they can get it at all) in the XJ which will be a fair bit lighter than the S. Posts above make a good point. These cars are not bought to be driven fast. Fast is relative - you will still be talking 8.5 sec to 60 - maybe less.
