2008	4dr Sedan 255-horsepower 3.1L V6 6-speed shiftable automatic AWD	It is @ least 4 mpg better hwy & city see full Audi A6 / S6 / RS6 review
2006	4dr Sedan 255-horsepower 3.1L V6 6-speed shiftable automatic AWD	It's hard to imagine such a powerful luxury car can get such great gas mileage. On a recent trip to Montreal I calculated my fuel economy to be somewhere in the 27mpg range....incredible! see full Audi A6 / S6 / RS6 review
2006	4dr Sedan 255-horsepower 3.1L V6 6-speed shiftable automatic AWD	better then 28 mpg on highway due to transmission gearing see full Audi A6 / S6 / RS6 review
2006	4dr Sedan 255-horsepower 3.1L V6 6-speed shiftable automatic AWD	Despite the performance of the A6 3.2 it delivers great mpg for such a large car. It excels on the open road. With cruise it is possible to achieve a range of 650+ miles on a tankful. see full Audi A6 / S6 / RS6 review
2006	4dr Sedan 255-horsepower 3.1L V6 6-speed shiftable automatic AWD	With the FSI and V6, I regularly see 27 mpg in city. And arround 30-32 mpg highway (no A/C on, and cruising at 80 mph). see full Audi A6 / S6 / RS6 review
2006	4dr Sedan 255-horsepower 3.1L V6 6-speed shiftable automatic AWD	21=22 mpg in cit/commute/highway driving -- pretty good for a large luxury car that weighs 4000+ pounds. see full Audi A6 / S6 / RS6 review
2004	4dr Sedan 220-horsepower 3.0L V6 6-speed shiftable CVT FWD	Typically 22-24 in-town and 29-31 on the road. Excellent economy for car size and level of comfort. see full Audi A6 / S6 / RS6 review

2006	4dr Sedan 335-horsepower 4.2L V8 6-speed shiftable automatic AWD	this is not a car to be used as a city daily driver -- the best mpg you will get in all city driving is 12mpg see full Audi A6 / S6 / RS6 review
2002	4dr Sedan turbocharged 250hp 2.7L V6 6-speed manual AWD	For a car that requires 91+ octane, it would be nice if it got better gas mileage in city driving (around 16-18 mpg). The mileage on the highway is much better (up to 26 mpg). see full Audi A6 / S6 / RS6 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

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
