2004 Infiniti G Fuel Economy: Cons
YearBody/PowertrainComment
2004 4dr Sedan 260-horsepower 3.5L V6
5-speed shiftable automatic AWD
got between 14 and 17 mpg in the city
2004 4dr Sedan 260-horsepower 3.5L V6
6-speed manual RWD
The G35 takes premium gas and from my research it looked like it would average about 10 mpg less than the Solara.
2004 4dr Sedan 260-horsepower 3.5L V6
5-speed shiftable automatic AWD
16-17 city/24-25 highway
2004 4dr Sedan 260-horsepower 3.5L V6
5-speed shiftable automatic RWD
Currently get 25-27 highway and 21=22.5 in the city. Live in extremely mountainous terrain, so mpg would be higher in a flat area such as Nebraska or Kansas. I would have added a 6th gear and kept the power.
2004 2dr Coupe 280-horsepower 3.5L V6
5-speed shiftable automatic RWD
At the very best, my combined fuel economy never got above 20.4 MPG and is recenly under 19.
