Look for the M271 Engine Series article - Misc near the bottom of the index page.
With supercharging, direct injection, balance shafts, and [I think] ULEV certification, these engines should be less thirsty and about the same in power for each of the older engines that they replace in the lineup.
Since the Coupe is the only MB currently sold here with a 4 cyl, and since there will no doubt be only the one engine choice for us, all of the verbiage about the rest of what the new family of 4 cyls will offer is beside the point.
Power and torque will be VERY slightly less than the current 2.3, but fuel consumption, smoothness, quiet, and emissions all favor the new engine. [Long story, but this should have happened about 5 years ago, however MB botched an earlier attempt to replace all of the old-gen 4s in the lineup...they are ready now to get on with it.]
