I have been getting a steady 13.5 MPG 65/35 hwy city. Pretty horrendous. Most other owners have told me its about normal. Mostly drive in sport. Engine has 2600k. I get about 220 miles to the fill up. IMO this is terrible. I had a 03 350z worked to hell and i would gun the throttle everyday numerous times and still get 17mpg average and 29 highway from a 300hp 2 seater. I barely get 21 on the highway with this car. Honestly don't care about the consumption but what does get me mad is they state this car gets 18mpg straight city!!! I drive on a few back roads and then im on the highway to work and im getting 13!!! the fuggg

 

About to hit 40,000 miles and I still get 18-19mpg on each tank with mostly highway driving either on normal/sports mode. Its a 60/40% of the time I'm either on those two driving modes. Pretty bad gas mileage but I don't really care, I just drive and fill her up as needed. Haha I'll care when gas is $4+ gallons again.

 

My wife has the 200t, and she's getting a pretty fantastic 36 MPG.
A lot of highway driving though.

Although at small throttle openings, it has a four cylinder drone that isn't as sweet as a six, and at v small throttle openings, we can tell that the turbo is not on song, such that slightly wider throttle openings are prone to turbo lag.

Open the throttle much wider and the turbo comes on song, with little lag & a sweeter sound.

My GS350 gets about 21.9 MPG...

I have a 2014 Lexus is 250 and i average around 27 mpg with about 60% highway driving and 40% city driving. I also almost always drive it in eco mode.

 

Virtually all cars tend to get better gas mileage as they get more miles on them. But yeah winter always sucks with all the light ends in the gasoline for winter blend.

I just picked up my 2016 IS300 the other day. Got about 300km to the first half tank. but the second half of the tank always disappears faster, so shall see what this first tank gets me.

 

How many miles on the wife's car? I'm getting about 20/21 on average( 70/30 hwy/city), car has about 6000 miles. I hope this improves as the miles accumulates.So far not impress with the 200t fuel usage...
