TrueDelta Reviews the Real Gas Mileage of the Buick Regal

Buick Regal Real Gas Mileage: Cons
YearComment
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
YearBody/PowertrainComment
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
