4dr Sedan 200-horsepower 3.8L V6 4-speed automatic FWD
Thus far, I have averaged 23 and 26 mpg, both times have had roughly a 70 mile highway trip out of 200 miles. Overall, I find this to be acceptable.

4dr Sedan 303-horsepower 5.3L V8 4-speed shiftable automatic FWD
Great V8 exhaust note and instant acceleration comes at the cost of about 19 mpg in combined driving, versus 25 with my new car. That is a 30% increase. (the new car is 600 pounds lighter though...)

4dr Sedan 303-horsepower 5.3L V8 4-speed shiftable automatic FWD
17-19 mpg in the city. 25 If I drive on the intersate. 30 is possible at 60mph. Most of my driving is in the city. The beautiful v8 makes it impossible to stay out of the gas, but it can run on REG fuel.
