on a recent trip to the NJ shore (about 80 miles), i noted mileage of 32.7 mpg (eco mode, average speed ca. 75 mph, no bumper -to -bumper traffic). now this was exceptional to me, and significantly better than that claimed by GM. of course, to even things out, most of my driving is city driving--20 to 30 mph. in my last look-see, i noted 14.1 mpg, shown on the "last 50 miles" gauge. oh well.
