2013 2dr Coupe turbocharged 211hp 2.0L I4
8-speed shiftable automatic AWD
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

2011 2dr Coupe 354-horsepower 4.2L V8

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
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

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

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
 

TrueDelta Reviews the Real Gas Mileage of the Lexus GS

Lexus GS Real Gas Mileage: Cons
YearComment
In casual suburban driving the trip computer reported between 22 and 23 mpg, splitting the difference between the EPA ratings of 19 city and 26 highway. When I made the engine sing mpg dropped into the high teens. Slip into Eco and drive the GS like a Prius, and 25 is barely doable. Not bad for a 306-horsepower, two-ton, all-wheel-drive sedan. But the torquier Audi A6 3.0T and BMW 535i xDrive do a little better, especially on the highway. The Teuton's turbos help a little here, but most of the blame/credit goes to their respective transmissions. If and when Lexus fits the GS AWD with the eight-speed automatic already offered in the RWD car, it'll likely catch up. see full Lexus GS review

I have been averaging 26 MPG (indicated) in mixed suburban and highway driving, which I think is pretty good. see full Lexus GS review
2008 4dr Sedan 292-horsepower 3.5L V6 Hybrid
6-speed shiftable CVT RWD
For 340 hp and a 0-60 of 5.2 seconds, I consider an average of 24 in the city and 33 on the highway to be incredible. If you really feather the gas and stick to 65 on the highway you can get around 36-38 mpg. see full Lexus GS review
2007 4dr Sedan 292-horsepower 3.5L V6 Hybrid
6-speed shiftable CVT RWD
Low consumption in city and stop and go traffic Significant fuel savings in typical German highway driving - plenty of acceleration to and braking from high speeds. The hybrid drivetrain minimises the cost of this compared to conventional petrol power see full Lexus GS review
