Cadillac STS Real Gas Mileage: Cons
YearBody/PowertrainComment
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

2008 4dr Sedan 272-horsepower 3.5L V6
6-speed shiftable automatic FWD		 Approximately 30 mpg highway and good mileage around town, too. Even with the premium fuel requirement the ES is still not very expensive to keep fueled. see full Lexus ES review

2007 4dr Sedan 272-horsepower 3.5L V6
6-speed shiftable automatic FWD		 For such a large & powerful car, fuel economy is quite good. Driving a ~100 mile/day round trip commute in bumper-to-bumper traffic, I get 24-28 mpg. see full Lexus ES review
Lexus ES Real Gas Mileage: Cons
YearBody/PowertrainComment
2008 4dr Sedan 272-horsepower 3.5L V6
6-speed shiftable automatic FWD		 With the high price of gasoline, any six-cylinder vehicle can be considered more than necessary for a daily commute. Still, averages of 22.5 MPG are not too bad. see full Lexus ES review
