TrueDelta Reviews the Real Gas Mileage of the Lexus GS

Lexus GS Real Gas Mileage: Cons
Year	Comment
	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

Year	Body/Powertrain	Comment
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

Subaru Legacy Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2013	4dr Sedan 256-horsepower 3.6L H6 5-speed shiftable automatic AWD	The downside of the H6 is not great gas mileage, but for what you are getting, it is not bad. On the highway with cruise control have managed to get about 30 mpg. In a mix of city and highway it gets 23 mpg. In city only it gets 18 mpg. Again, for AWD not bad, but not great. Want better gas mileage, get the H4 engine. see full Subaru Legacy review
2010	4dr Sedan 170-horsepower 2.5L H4 6-speed shiftable CVT AWD	With the CVT transmission, rpms stay low and there is no shifting saving on fuel. see full Subaru Legacy review

2010	4dr Sedan 170-horsepower 2.5L H4 6-speed manual AWD	I average 43mpg in a little over half highway driving. I get 55mpg on the highway and about 35mpg in city driving. This is very impressive considering this car's performance. see full Subaru Legacy review

Subaru Legacy Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2010	4dr Sedan 170-horsepower 2.5L H4 6-speed manual AWD	A bit thirstier than I had hoped - but the AWD probably has a lot to do with that. see full Subaru Legacy review
2009	4dr Sedan 170-horsepower 2.5L H4 4-speed shiftable automatic AWD	The fuel economy with a 4 cylinder 170 hp engine is pretty disappointing at 22-23 mpg. The AWD system is responsible for some of the loss but I also drive an AWD Acura TL SH-AWD with a 6 cylinder 305 hp engine that is only marginally worse at 18-19 mpg. see full Subaru Legacy review
2008	4dr Sedan 245-horsepower 3.0L H6 5-speed shiftable automatic AWD	I do not dislike the fuel econ, its AWD and I knew that going into the purchase, after you walk away from a totaled vehicle, safety becomes the prioroty over fuel econ. Have been able to get 32mpg out of both vehicles with smart driving see full Subaru Legacy review

2005	4dr Wagon turbocharged 250hp 2.5L H4 5-speed manual AWD	poor gas mileage for its size. getting about 18 mpg average in mixed driving. the car also requires 91+ octane. see full Subaru Legacy review
2005	4dr Sedan 168-horsepower 2.5L H4 4-speed shiftable automatic AWD	AWD system is a plus, overall, but fuel economy suffers. see full Subaru Legacy review
