To get good mileage city driving you gotta leave it in auto. You can get about 18mpg on a cool day and 15 to 16 mpg on a hot day. If i switch gears and are hooning around I'll get somewhere around 13mpg. For a 6.2ltr v8 that at this moment I'm at 444.3 rwhp/510bhp I think I'm getting great mileage.
I'm expecting the same from the C8

My Ls1 and ls7 cars always returned exceptional mpg.
