Just discovered this, the OM654:

https://en.wikipedia.org/wiki/Mercedes-Benz_OM654_engine

2.0 liters, 192 hp, 295 ft, lbs. I think those figures are with the twin turbo, the single turbo puts out 150 hp. I think.

Came out in the 2016 E-Class 220d so apparently I'm behind the curve again. Oh well.
