Year	Body/Powertrain	Comment
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
2010	2dr Coupe turbocharged 211hp 2.0L I4 6-speed manual AWD	Averaging 9L/100KM, without feeling too conservative. see full Audi A5 / S5 / RS5 review

Audi A5 / S5 / RS5 Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2011	2dr Coupe 354-horsepower 4.2L V8 6-speed manual AWD	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
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
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	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 Buick Regal

Buick Regal Real Gas Mileage: Cons
Year	Comment
2011	The Buick Regal and Chrysler 200 both weigh substantially more than just about any other front-wheel-drive midsize sedan. Add all-wheel-drive, and both weigh nearly two tons. Curb weight is the enemy of fuel economy. The Buick's turbocharged four-cylinder engine is more efficient than the Chrysler's V6, so it has an edge in the EPA's city test, 19 vs. 18 mpg. But the Chrysler's automatic transmission has three extra gears, for a total of nine, so it has the edge on the EPA's highway test, 29 vs. 27 mpg. The Ford Fusion, though far from light, has an edge over both: 22 mpg city, 31 mpg highway. see full Buick Regal review

2014	4dr Sedan turbocharged 259hp 2.0L I4 6-speed shiftable automatic FWD	Good mileage, 30-35 mpg on highway. see full Buick Regal review

Buick Regal Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2012	4dr Sedan turbocharged 270hp 2.0L I4 6-speed manual FWD	For being a turbo 4, I expected slightly better MPG (I average 26mpg mixed with premium). When adding in the Trifecta Performance tune on the car, I average around 29mpg, with the added HP/TQ. What gives, GM? Uncage this beast! see full Buick Regal review
2011	4dr Sedan 182-horsepower 2.4L I4 6-speed shiftable automatic FWD	City EPA mileage was lower than I would expect for a four cylinder--should easily best 20 vice 19. see full Buick Regal review
2003	4dr Sedan 200-horsepower 3.8L V6 4-speed automatic FWD	It gets 22 in town, 25 on the highway. see full Buick Regal review
