Audi A7 / S7 / RS7 Real Gas Mileage: Pros
Year	Comment
2014	Now for the second half of the Audi A7 TDI's one-two punch: its diesel engine. No one denies the efficiency of diesels, and the latest Audi V6 doesn't disappoint. In the EPA's tests the TDI achieves 24 mpg city, 38 mpg highway. The gas engine's 18/28 ratings are impressive for a powerful gas V6 in a heavy all-wheel-drive car, but are no match for the diesel's. In my real-world driving the A7 TDI's trip computer generally reported mid-30s in the suburbs and about 40 on the highway (a little under this number on 70-mph Interstates, a little over it where speed limits were lower). Diesel can be unpleasant to put in the car--it's slimy and does not evaporate if spilled like gas does--but the A7 TDI can go up to 800 miles between fill-ups. In comparison, the gas V6 manages low 20s in the suburbs and high 20s on the highway. This said, the competing diesel from BMW is even more efficient. see full Audi A7 / S7 / RS7 review

Mercury Montego Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2007	4dr Sedan 203-horsepower 3.0L V6 6-speed automatic FWD	It is great for such a big car. 30 mpg is pretty easy for highway cruising, and mixing driving will do 24-25. see full Mercury Montego review
2005	4dr Sedan 203-horsepower 3.0L V6 6-speed automatic FWD	A large car that gets over 20 MPG in city driving is great. The 29 MPG highway rating is nice, but the car is mainly used as a grocery getter / errand runner. see full Mercury Montego review
2005	4dr Sedan 203-horsepower 3.0L V6 6-speed automatic FWD	Surprisingly good fuel mileage. 24 city/31 Hwy. see full Mercury Montego review
