TrueDelta Reviews the Real Gas Mileage of the Lexus IS

Lexus IS Real Gas Mileage: Cons
YearComment
The 2014 IS 350 manages 19 mpg in the EPA city test, and 28 in the highway test. While these figures tie those for the Cadillac ATS 3.6, they're short of the 23/33 achieved by the BMW 335i. Also, with both the BMW and the Cadillac you can step down to more efficient turbocharged four-cylinder engines. With the new IS, your only other engine option is a small V6, and its fuel economy is only a couple mpg better than that of the big V6 (21/30). The BMW has a further advantage: you can set the steering and suspension to "Sport" without forcing the transmission to hold a lower gear. In the 2014 IS 350 F Sport, the sport modes are "all or nothing." Select one to firm up the steering and suspension, and the transmission won't shift beyond sixth gear, reducing fuel economy. Lexus should follow Audi's lead and offer an "Individual" mode, where each system (powertrain, steering, suspension, etc.) can be set separately. see full Lexus IS review

6-speed shiftable automatic RWD		 At around 200hp, it isnt the fastest luxury sedan. However, on my roadtrip across the eastern / mid eastern USA I was able to get ~33 ish mpg (computer reported) on flat terrain and premium fuel. City mpg is what I expect,22-25ish. But I think it is great as a long distance comfortable vehicle. see full Lexus IS review

2009 4dr Sedan 204-horsepower 2.5L V6
6-speed shiftable automatic RWD		 Wish it got better fuel economy for such a small car and engine... Sticker is 21/29, I'm averaging 27MPG (computer read); avg on hwy is about 33-34 mpg while city is about 19-23mpg. Engine variety would help, a 4 cyl + turbo or something, but toyota/lexus isn't exactly known for that. see full Lexus IS review
2002 4dr Wagon 215-horsepower 3.0L I6
5-speed shiftable automatic RWD		 For a small, relatively modestly powered car, it gets poor economy. Corvettes and most Porsches get better economy. see full Lexus IS 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
