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

I have been averaging 26 MPG (indicated) in mixed suburban and highway driving, which I think is pretty good. 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

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
 

TrueDelta Reviews the Real Gas Mileage of the Toyota Avalon

Toyota Avalon Real Gas Mileage: Pros
YearComment
2013 The Avalon's EPA ratings of 21 mpg city, 31 mpg highway are the best of any V6-powered large sedan. The Azera's numbers aren't too far behind (20/29). The LaCrosse's are (17/27). In our suburban driving we roughly matched the city figure. On the highway, though, we measured about 27. A number of factors might explain the shortfall. With a 70 mph limit, we were cruising well above the maximum speed of the EPA test cycle. Also, every seat was occupied and the trunk was chock full of luggage. Desire better fuel economy? Well, for the first time the Avalon is also available with a hybrid powertrain, specifically the same 200-horsepower (combined) unit available in the Camry. With this engine, the EPA ratings are 40/39. But you'll give up the more effortless acceleration and sweeter sound of the 268-horsepower V6. While the 3.5-liter V6 has changed very little since its introduction in the 2006 Avalon, and lacks the latest technology such as direct injection, it feels plenty strong and is among the best-sounding V6s. At low speeds and in turns traction is the limiting factor. All-wheel-drive would help, but unlike in the Buick isn't an option. The transmission remains the same six-speed automatic Toyota has offered since 2007. It's smooth and responsive, especially in sport mode (offered with the XLE Touring and Limited). If you desire to call the shifts yourself anyway, this can be done via either paddles flanking the steering wheel or the lever. Econ mode makes top mpg easier to attain by dulling throttle responses and quickening upshifts. see full Toyota Avalon review

Excellent mileage the entire 8 years I have owned this car. Usually I get 22-24 in town and well over 32 on the highway sometimes up to 35 mpg if I keep at 65 when the RPM runs around 2000. see full Toyota Avalon review
