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

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

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

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
