2013 2dr Coupe turbocharged 211hp 2.0L I4

Mileage seems to have leveled out at about 27 mpg with a 60/40 mix of highway and suburban driving. On longer trips, it has been as high as 30 mpg while driving a steady 75 mph. see full Audi A5 / S5 / RS5 review

2009 2dr Coupe turbocharged 170hp 2.0L I4 Diesel

Fuel economy is fair when going for a long ride, the car is AWD and heavy. I did however expect a somewhat lower fuel consumption when driving short-distance. see full Audi A5 / S5 / RS5 review

2013 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD
What the powertrain giveth, the fuel economy taketh away. Nissan's VQ engines just seem to be thirsty - if you commute in heavy traffic, especially for short trips, don't be surprised at 15.5-16 mpg tanks. I don't know what mostly-highway commuting would look like, but maybe 22-25 mpg depending on driving style. see full Infiniti G review
2010 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD
To be honest, it is exactly what I expected, so no real beefs with it. That said, if you are looking for a car that gets better than 19 or so combined, this is not it. Decent freeway miles (24-27/g) but in city it is hard to beat 16/g. see full Infiniti G review

You do not buy a performance car and expect to get good gas mileage. At a 5 mpg or greater difference from my last car, it is taking some getting used too. see full Infiniti G review

2009 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD
With such a large displaced engine and so much power you will find that you will have so-so mpg if you drive mainly in the city like I do. Especially if you are a "spirited" driver like I tend to be. I am averaging about 14-16mpg 95% city. On the highway its a different story. I have averaged up to 28mpg @ 78mph, I kind of wish I drove more on the highway. see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6

While not terrible, ~20mpg is by no means phenomenal. Relatively comparable cars get ~23-27mpg, but typically also have smaller engines which explains a good portion of the difference. see full Infiniti G review
