I'm waiting to see how the Cruze diesel looks, too, but truth be told, with the improvements in gas mileage lately, I'm not sure a diesel would be worth it anymore. My Sonata has gotten almost 37mpg on the highway, not consistently, but I do have one outlier at 36+ and the usual mileage is in the 33-35 range, and some of the "eco" models out there are claiming 40+.
