GREEN | 6 out of 10
19 mpg city, 27 highway (G37 Coupe automatic); 17/25 (G37 Coupe manual); 18/25 (G37x Coupe automatic); 17/25 (G37 Convertible auto); 16/24 (G37 Convertible manual)
The EPA ratings for the car put it at 16 mpg city and 24 mpg highway, but we only averaged 16.2 mpg in combined city and freeway driving.
The 2012 Nissan G37 Coupe and Convertible aren't at all impressive for gas mileage--but then again, it isn't a priority for many two-door performance-car shoppers.
With EPA fuel economy figures of up to 19 mpg city, 27 highway, the 2012 Nissan G37 Coupe is less efficient than the typical mid-size V-6 sedan; but in all fairness, it's about the same on gas as six-cylinder luxury sports cars like the BMW Z4 and Porsche Boxster. With turbocharged four-cylinders on offer for the new Z4 and SLK, though, this class is becoming more fuel-efficient and green; Infiniti offers a G25 sedan, with a lower-output engine that gets about 2 mpg more, but it's sticking to its guns and only offering the higher-output engine in Coupes and Convertibles.
The extra weight of the G37 Convertible also drags gas mileage down compared to the Coupe; the drop-tops average about 1 mpg lower with either transmission--for ratings as low as 16 mpg city, 24 highway.
The 2012 Infiniti G37 Coupe isn't as fuel-efficient as some other models in this class; and Convertibles are particularly thirsty.
