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

From a 17mpg average Chevy truck to NEVER getting less than 29mpg city, need I say more? Well okay, how about 37mpg on a freeway run. I have only got 13000 miles on the vehicle, and can imagine the fuel economy will improve still more. see full Kia Rio review
