2012 4dr SUV 273-horsepower 3.7L V6
6-speed shiftable automatic FWD		 EPA ratings of 17/24, but I've averaged barely 18 overall in my first 1200 miles...hoping for a slight improvement after break-in. UPDATE- as of 02/11/2013, I am averaging 20-21mpg overall with 4200 miles on the clock. On a recent 380-mile interstate trip, I managed 22.8mpg with the cruise set at 80mph. see full Mazda CX-9 review

2008 4dr SUV 273-horsepower 3.7L V6
6-speed shiftable automatic AWD		 The AWD feature does use more gas than a FWD vehicle. Averages about 17-18 city and about 20 highway. see full Mazda CX-9 review

6-speed shiftable automatic FWD		 The fuel economy was lower than for the Murano. The plus is that it uses regular. see full Mazda CX-9 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

2009 4dr Sedan 303-horsepower 3.5L V6
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
