2005 Cadillac CTS Real Gas Mileage: Cons
YearBody/PowertrainComment
2005 4dr Sedan 255-horsepower 3.6L V6
5-speed automatic RWD		 I get 20-21mpg on my commute which is about 70%hwy, and normally 25-27 with pure freeway driving, it just seems with technology today they could kick that up to 23-24 and 28-30 respectively. see full Cadillac CTS review
2004 4dr Sedan 255-horsepower 3.6L V6
5-speed automatic RWD		 Average at best. Yea it is a heavy car with all the safety eqipment. see full Cadillac CTS review
