2002 Infiniti G Real Gas Mileage: Cons
YearBody/PowertrainComment
2003 4dr Sedan 260-horsepower 3.5L V6
5-speed shiftable automatic RWD
Very poor city mpg, almost as bad as large SUV.
2003 4dr Sedan 260-horsepower 3.5L V6
5-speed shiftable automatic RWD
Highway fuel economy should be better, maybe higher fifth gear for lower revs at highway speeds.
2003 2dr Coupe 280-horsepower 3.5L V6
5-speed shiftable automatic RWD
Freeway or city driving, AC or no AC, always average out to be around 20-21. No more no less.
2003 2dr Coupe 280-horsepower 3.5L V6
6-speed manual RWD
Horrible fuel milage. Seems like they under-rated the horsepower and over rated the fuel economy.
2003 4dr Sedan 260-horsepower 3.5L V6
5-speed shiftable automatic RWD
City fuel economy is terrible. (15L/100km) Highway fuel economy is not as good either. (8L/100km @ 105km/hr) if going any faster, the fuel economy get worse!
