TrueDelta Reviews the Real Gas Mileage of the Audi A4 / S4 / RS4

Audi A4 / S4 / RS4 Real Gas Mileage: Pros
Year	Comment
2017	Everyone has been switching to turbo fours in pursuit of fuel economy. Despite being such a quick car, the new A4 manages EPA ratings of 25 mpg city, 33 mpg highway with front-wheel drive and 24/31 with all-wheel drive. If you're willing to trade off some performance for even better numbers, and don't require all-wheel drive, the new 190-horsepower "ultra" achieves 27/37. In my driving the A4's trip computer reported averages as high as 36 mpg in the suburbs and 34 mpg on the highway. Mid-to-high 20s happened without even trying to be economical. Lexus, perhaps because it's new to turbocharging, can't match these figures. The IS 200t scores 22/32, while the IS 300 (with AWD) manages only 19/26, a full five mpg short of the Audi. see full Audi A4 / S4 / RS4 review

Audi A4 / S4 / RS4 Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
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 6-speed manual AWD	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
2010	4dr Sedan supercharged 333hp 3.0L V6 7-speed automated manual AWD	27mpg at 70mph see full Audi A4 / S4 / RS4 review
2009	4dr Sedan turbocharged 211hp 2.0L I4 6-speed manual AWD	30mpg is easy to achieve with modest driving, even with the turbo. see full Audi A4 / S4 / RS4 review
2008	4dr Sedan turbocharged 200hp 2.0L I4 6-speed manual AWD	Great fuel economy if driven easily, but is a great performer if pushed. Best of both worlds. see full Audi A4 / S4 / RS4 review
2008	4dr Sedan turbocharged 200hp 2.0L I4 6-speed shiftable automatic AWD	averaging 24.4 mpg - not bad see full Audi A4 / S4 / RS4 review
2008	4dr Sedan turbocharged 200hp 2.0L I4 6-speed manual AWD	higher than others with less power see full Audi A4 / S4 / RS4 review
2008	4dr Wagon turbocharged 200hp 2.0L I4 6-speed shiftable automatic AWD	Good tradeoff of performance and mileage. Previous VW 1.8t owner, viewed this as an upgrade. see full Audi A4 / S4 / RS4 review
2008	4dr Sedan 420-horsepower 4.2L V8 6-speed manual AWD	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

Year	Body/Powertrain	Comment
2010	4dr Sedan turbocharged 211hp 2.0L I4 6-speed shiftable automatic AWD	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 7-speed automated manual AWD	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	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
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
2007	4dr Sedan 255-horsepower 3.1L V6 6-speed shiftable automatic AWD	only averaging 17 mpg see full Audi A4 / S4 / RS4 review
2007	4dr Wagon turbocharged 200hp 2.0L I4 6-speed shiftable automatic AWD	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 255-horsepower 3.1L V6 6-speed shiftable automatic AWD	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
2006	4dr Sedan 255-horsepower 3.1L V6 6-speed manual AWD	Not bad, but not great either see full Audi A4 / S4 / RS4 review

2007	4dr Sedan 306-horsepower 3.5L V6 5-speed shiftable automatic AWD	My average for the life of the car is 21MPG. Not too bad for a car with this power and my lead foot. see full Infiniti G review

Infiniti G Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2013	4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic RWD	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
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
2010	4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD	Fuel economy is poor - about 19 MPG average. 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
2009	2dr Coupe 330-horsepower 3.7L V6 7-speed shiftable automatic AWD	average 18 in town 24 highway. 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 6-speed manual RWD	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
2008	4dr Sedan 306-horsepower 3.5L V6 5-speed shiftable automatic AWD	Takes a lot of fuel... 14L/100km about. see full Infiniti G review
2008	4dr Sedan 306-horsepower 3.5L V6 5-speed shiftable automatic RWD	Not too great. My average is 19 - 20 mpg, mostly city. see full Infiniti G review
