What Our Members Are Saying about the Real Gas Mileage of the 2008 Audi A5 / S5 / RS5

2008 Audi A5 / S5 / RS5 Real Gas Mileage: Cons
YearBody/PowertrainComment
2009 2dr Coupe turbocharged 170hp 2.0L I4 Diesel
6-speed manual AWD		 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
2008 2dr Coupe 354-horsepower 4.2L V8
6-speed manual AWD		 Thirsty V8 coupled with a car that was born to be driven hard equals mid-teen MPG in mostly non-highway driving. see full Audi A5 / S5 / RS5 review
2008 2dr Coupe 354-horsepower 4.2L V8
6-speed manual AWD		 drinks too fast when driving is more aggressive see full Audi A5 / S5 / RS5 review
2008 2dr Coupe 354-horsepower 4.2L V8
6-speed manual AWD		 It is not great, and if you have fun with the car, you will get less than 15MPG see full Audi A5 / S5 / RS5 review
