I get pretty close in my 2014 Cruze. It's listed at 38 highway (no idea what they consider highway speed) and on my two trips to Cleveland last year, I got 34.4 the first trip and 35 even on the second trip. And that includes all the downtown Cleveland driving I did, and my interstate speeds of 71-72 mph.
The couple times I've figured out what I get for a normal week of driving…back and forth to work, driving to Battle Creek & Kalamazoo on the weekend, etc. I tend to avg. 31-32 mpg. My old 2007 Focus hatchback got about 30-31 in an average week and usually got 34 mpg on long interstate trips.
