YearBody/PowertrainComment
2012 4dr Sedan turbocharged 211hp 2.0L I4
6-speed manual AWD
Very surprised! Drive 80 Hwy / 20 City driving. If I watch how I accelerate (cruising speed not so much; I drive 110-125 on hwy). Averaging 6-7.5L/100km. (700+km per 55L tank every fill up). see full Audi A4 / S4 / RS4 review
2011 4dr Sedan supercharged 333hp 3.0L V6
7-speed automated manual AWD
Despite the supercharger and high performance, this vehicle gives me about 6.8l/100km on the highway on average - amazing fuel efficiency. This is a very welcome bonus. see full Audi A4 / S4 / RS4 review
2010 4dr Sedan turbocharged 211hp 2.0L I4

Better than expected highway mileage. Averaged 34mpg on a 350-mile trip last weekend, keeping speed to about 60mph. Commuting mileage is acceptable. see full Audi A4 / S4 / RS4 review

EPA ratings are accurate. I've seen as low as 12 mpg in the city, and up to 22 mpg on highway journies. I average 15 mpg in mostly-city driving. see full Audi A4 / S4 / RS4 review

Good tradeoff of performance and mileage. Previous VW 1.8t owner, viewed this as an upgrade. see full Audi A4 / S4 / RS4 review

Great fuel economy if driven easily, but is a great performer if pushed. Best of both worlds. see full Audi A4 / S4 / RS4 review

2010 4dr Sedan turbocharged 211hp 2.0L I4

Quattro and turbocharged engine form a thirsty combination. I would have expected 700+ highway kms but typically get only 600. see full Audi A4 / S4 / RS4 review
2010 4dr Sedan supercharged 333hp 3.0L V6

Avg about 18-20 mpg on real world highways. City can be as poor as 12-14. see full Audi A4 / S4 / RS4 review
2008 2dr Convertible 420-horsepower 4.2L V8
6-speed manual AWD
No 420hp car is going to sip fuel, but the fuel tank is small (14.5 gallons) and thus needs filled too often. see full Audi A4 / S4 / RS4 review
2008 4dr Sedan turbocharged 200hp 2.0L I4
6-speed manual AWD
The diesel version has MORE torque and power AND has a far better range (about 700 miles for 2L diesel engine), I dislike the 22-24 mpg for the combined driving (mostly city). Those are still good numbers for its class. Sucks when have to pay $3.87/gallon see full Audi A4 / S4 / RS4 review

I guess this is average for a car like this. Keep off the turbo and things improve. see full Audi A4 / S4 / RS4 review
2007 4dr Sedan 255-horsepower 3.1L V6
6-speed shiftable automatic AWD
Overall fuel economy barely acceptable on premium fuel. Highway fuel economy is fine but city economy stinks. 21 MPG driving 70% highway miles. However, better than Infiniti G35x see full Audi A4 / S4 / RS4 review
2006 4dr Wagon turbocharged 200hp 2.0L I4
6-speed manual AWD
Horrible fuel economy in the city. If you are a spirited driver, do not expect decent mileage in the city despite being a 4 cylinder. If you do a lot of highway driving, it may be more acceptable, especially if you don't accelerate too hard. see full Audi A4 / S4 / RS4 review
2006 4dr Wagon 255-horsepower 3.1L V6

not as good as it should be in my opinion, although in line with the (newer more realistic) EPA figures. see full Audi A4 / S4 / RS4 review

Can live with it because of the performance, but wish the mileage was better and premium fuel was not required. 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
2010 4dr Sedan 328-horsepower 3.7L V6

Fuel economy is poor - about 19 MPG average. 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
2009 2dr Coupe 330-horsepower 3.7L V6
7-speed shiftable automatic RWD
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

2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic AWD
5th gear is short and really infringes on getting decent mileage (15-17 in mixed and 22-23 hwy). Accurate EPA figures but the new 7 speed AT for 2009 really helps. 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
