Buick Enclave Real Gas Mileage: Pros
YearBody/PowertrainComment
2009 4dr SUV 288-horsepower 3.6L V6
6-speed shiftable automatic AWD		 More than reasonable for a 5000 lb vehicle. Benefits of aero design ( for an SUV ) and six speed transmission both contribute. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic FWD		 24 - 28 mpg summer highway driving see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic FWD		 for an 8 passenger vehicle that can tow 4,500 pounds. I cannot complain about 19.3 mpg city and 24.7 mpg highway. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic AWD		 Better than competition with regular gas see full Buick Enclave review

Buick Enclave Real Gas Mileage: Cons
YearBody/PowertrainComment
2011 0 The fuel economy is abysmal and as far as I know, Buick STILL doesn't offer a hybrid option. The best mileage I've been able to get on long road trips with mostly highway driving is 22-23 mpg. City driving, however, stubbornly stays at 14-15 mpg, no matter what I do! :( see full Buick Enclave review
2009 4dr SUV 288-horsepower 3.6L V6
6-speed shiftable automatic FWD		 Well under (15-20%) below the EPA ratings, though the engine is STILL brand new (<400 miles total). see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic AWD		 In town much less than advertised. O.K. (18-19) on freeway. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic AWD		 This is the one thing that is a weak point. at 12-16 MPG, this car could use a larger and more efficient engine. Had GM not folded, there was talks of a hybrid version (which still may come out as a Caddy) which we would definitely buy without hesitation. see full Buick Enclave review

6-speed shiftable automatic AWD		 Car is still in break-in period, but not seeing anything close to advertised mileage. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic AWD		 Hey, at $4.00/gallon getting only 22 mpg hurts. We take the econo-car most of the time. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic FWD		 It actually gets great mileage for its size and weight, but hey, its not a Prius. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic FWD		 Bad around town see full Buick Enclave review

2006 4dr Sedan 320-horsepower 4.6L V8
5-speed shiftable automatic RWD		 16 city/21 highway. Buy it only if you can afford it with out complaining. see full Cadillac STS review
2005 4dr Sedan 320-horsepower 4.6L V8
5-speed shiftable automatic AWD		 This car is thirsty. I live in flat country and I get 15 mpg with 80% highway traffic. I only get 19 mpg on trips. It probably needs a 6th speed overdive for the highway. see full Cadillac STS review
