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

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

The downside of the H6 is not great gas mileage, but for what you are getting, it is not bad. On the highway with cruise control have managed to get about 30 mpg. In a mix of city and highway it gets 23 mpg. In city only it gets 18 mpg. Again, for AWD not bad, but not great. Want better gas mileage, get the H4 engine. see full Subaru Legacy review

The fuel economy with a 4 cylinder 170 hp engine is pretty disappointing at 22-23 mpg. The AWD system is responsible for some of the loss but I also drive an AWD Acura TL SH-AWD with a 6 cylinder 305 hp engine that is only marginally worse at 18-19 mpg. see full Subaru Legacy review
