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

2002	4dr Sedan 200-horsepower 3.8L V6 4-speed automatic FWD	HORRIBLE. 12-16mpg combined with both city and driving. see full Pontiac Grand Prix review

Year	Body/Powertrain	Comment
2006	4dr Sedan 303-horsepower 5.3L V8 4-speed shiftable automatic FWD	Great V8 exhaust note and instant acceleration comes at the cost of about 19 mpg in combined driving, versus 25 with my new car. That is a 30% increase. (the new car is 600 pounds lighter though...) see full Pontiac Grand Prix review
2005	4dr Sedan 303-horsepower 5.3L V8 4-speed shiftable automatic FWD	17-19 mpg in the city. 25 If I drive on the intersate. 30 is possible at 60mph. Most of my driving is in the city. The beautiful v8 makes it impossible to stay out of the gas, but it can run on REG fuel. see full Pontiac Grand Prix review
