17/25 (manual G37); 19/27 (auto G37); 18/25 (G37x)
Gas mileage isn't all that praise-worthy for the Infiniti G37; and considering the discontinuation of the G25 models, the efficiency of the G Sedan lineup has actually fallen for 2013.
G37 models with the manual gearbox are actually the least fuel-efficient, at 17/25; models with the automatic get up to 19 mpg city, 27 highway.
Those who are concerned about fuel efficiency should consider the somewhat larger M Hybrid; it carries EPA ratings of 27 mpg city, 32 highway, while it's still quite sporty and satisfying to drive.
Fuel-efficiency isn't a particularly strong trait for the Infiniti G37 -- even compared to other sport sedans.
