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
