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

I knew what gas mileage the S5 got long before I stepped onto the dealer lot. Still, I get 24 mpg on a full highway run. see full Audi A5 / S5 / RS5 review

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

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
