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

5-speed manual FWD		 On a recent trip from Charlottetown, PE, Canada to Halifax, NS my car averaged 35 miles per US gallon, or over 730km per tank of fuel. As a Merchandiser, my job requires a lot of city Driving and I average 600km per tank of gas see full Mazda Protege review

5-speed manual FWD		 The car does get excellent fuel economy- IF you can keep your foot out of it. I rarely succeed in that endeavor- the car is just too much fun to drive, the embodiment of "driving a slow car, fast." see full Mazda Protege review

5-speed manual FWD		 Not too bad, the roof rack hurts it a bit. gets a solid 22-25 driving 70-75 on highway. Does get 30mpg at 60 mph, but that speed will get you killed on California interstates. see full Mazda Protege review

Mazda Protege Real Gas Mileage: Cons
YearBody/PowertrainComment
2003 4dr Wagon 130-horsepower 2.0L I4
5-speed manual FWD		 Suburban fuel economy is acceptable, at nearly 30 mpg. But on the highway, with the engine spinning well over 3,000 rpm, fuel economy also struggles to crack 30. Many much larger, much more powerful cars achieve better highway fuel economy. Some owners have fitted the fifth gear from the related transmission in the Mazda6 to get more of an overdrive. see full Mazda Protege review
