Mercury Montego Real Gas Mileage: Pros
YearBody/PowertrainComment
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
 

TrueDelta Reviews the Real Gas Mileage of the Lexus GS

Lexus GS Real Gas Mileage: Cons
YearComment
In casual suburban driving the trip computer reported between 22 and 23 mpg, splitting the difference between the EPA ratings of 19 city and 26 highway. When I made the engine sing mpg dropped into the high teens. Slip into Eco and drive the GS like a Prius, and 25 is barely doable. Not bad for a 306-horsepower, two-ton, all-wheel-drive sedan. But the torquier Audi A6 3.0T and BMW 535i xDrive do a little better, especially on the highway. The Teuton's turbos help a little here, but most of the blame/credit goes to their respective transmissions. If and when Lexus fits the GS AWD with the eight-speed automatic already offered in the RWD car, it'll likely catch up. see full Lexus GS review

6-speed shiftable automatic RWD		 I have been averaging 26 MPG (indicated) in mixed suburban and highway driving, which I think is pretty good. see full Lexus GS review
2008 4dr Sedan 292-horsepower 3.5L V6 Hybrid
6-speed shiftable CVT RWD		 For 340 hp and a 0-60 of 5.2 seconds, I consider an average of 24 in the city and 33 on the highway to be incredible. If you really feather the gas and stick to 65 on the highway you can get around 36-38 mpg. see full Lexus GS review
2007 4dr Sedan 292-horsepower 3.5L V6 Hybrid
6-speed shiftable CVT RWD		 Low consumption in city and stop and go traffic Significant fuel savings in typical German highway driving - plenty of acceleration to and braking from high speeds. The hybrid drivetrain minimises the cost of this compared to conventional petrol power see full Lexus GS review
