My G37 gets much better gas mileage than my G35 coupe did. On my last tank, I got 23.4 miles per gallon with 75% highway. I'd say I get about 1-2 mpg average better than the G35 coupe (both 6MTs). If I drive with a feather foot, I can keep the online mileage indicator near 24-25 mpg. I took my car in for an oil change and got an '07 G35x sedan. With the same driving techniques (extremely light footed) - I couldn't get the indicator above the 20 mpg mark in mixed city/highway driving. Big big plus on the mileage in my book.
