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
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

2009 Audi A4 / S4 / RS4 Real Gas Mileage: Cons
YearBody/PowertrainComment
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
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
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
