Ward's Auto reports that "sources" have confirmed the oil-burning Cruze will achieve a highway fuel economy rating "in the range of 50 miles per gallon." Additionally, unlike the manual transmission-equipped, 42-mpg rated Chevy Cruze Eco (an automatic Eco is available, but its mpg rating is well below that of the manual), the diesel Cruze, according to Charlie Klein, GM's director of global mass, energy and aerodynamics, will be a fuel-sipping sedan regardless of which trans is bolted to the engine.
As for that engine, GM has unofficially confirmed that it will indeed be based on the 2.0-liter diesel that's found under the hood of the Holden Cruze CDX. In the Holden, the 2.0-liter mill pumps out 160 horsepower and 265 pound-feet of torque. One last bit of info: we hear that the diesel Cruze's torque will allow it to easily outrun the Cruze Eco.
