Poor fuel economy in our new NX200T

We traded a 2015 BMW X3 2.0 on a 2017 NX200T with comparable engine. The X-3 had an 8 speed trans and at 75 mph was turning 2000rpm and delivering 28-30 mpg.
This new Lexus is a 6 speed trans ( I was not happy about that) and at 75 mph it is revving at 2500 rpm and delivering a meager 23-25 mpg. This engine is just not properly geared to get decent mileage at this rpm. We also own a 2016 Fiat 500X that has a 9 speed trans mated to a 2.4L non turbo power plant that turns 1650 rpm at 75 mph and delivers a very consistent 27-29 mpg.

Congrats on the upgrade! Your engine needs time to break-in. You'll see MPGs improve a bit in several thousand miles -- maybe up to 10k miles. I agree; a 6-speed auto does seem a little old tech in the turbo NX, but I trust you knew that before pulling the trigger on it? We've also had a 2015 X3 with the turbo 4-cylinder. It was a decent performer and returned respectable fuel economy. Yet, after our HS hybrid and a few Prius, the only option for us was the hybrid NX. I did a dozen or more errands all over town in it today, and at not even 250 miles on the odometer, it was achieving 34.7 MPG. I also expect this number to improve once the engine gets broken in.
Don't sweat the small stuff ... enjoy it for the reasons you purchased it (which is likely to see your service advisor less frequently).

Our 2015 NX200T usually gets 24 to 25 mpg at 72 to 75 mph. Our last trip, it did a little better, returning 26 to 27. I don’t know if the difference was due to better fuel or winds or ?? We have 30K miles on the car so it’s definitely broken in. We are also disappointed with the usual highway mileage.
When you bought this car did you not see what the epa mileage was. It is very clear that it is 28 on the highway and this is based on 60 mph and yes, it is a six speed transmission. All this information was available to you before you bought the car. I agree that an eight speed would have been much better but Lexus thought best for this application to use a six speed. I trust there judgement on this.
I just came back from a 260 mile trip and for most of the trip I was doing 75 and got 29.5 going and 27 coming home when I was doing 80 most of the time. Try getting that mileage with a RX 350. You will be lucky to get 23. Wind also does have a lot to do with as well as traffic.

Mileage depends on a lot of factors, and 1 trip isn't going to give you an accurate gauge of the mileage. My 2016 nx is at 10k miles and i average ~20mpg driivng in city with lots traffic,stop signs, speed bumps. On a recent road trip of 100+ miles with cruise set at 65mph and in eco mode, i achieved 30mpg pretty easily. If you drive at a higher speed, or under higher load where the turbo is in boost, your mileage will go down substantially. Compared to my 2008 is350 or loaner rx350 i recently had, the nx gets very good gas mileage,

I got good mpg always with X5. Now I am seeing similar engine specs. on Audi turbo engines. Check the specs of Lexus turbo and 6 speed tranny may be a factor too. After break-in period mpg may improve.
More rpm = more gas consumption.

Buy an NX and complain about fuel mileage? All the EPA information is available online and on the window sticker.
We bought our F-Sport for the fun and reliability....but it turns out we get better than EPA mileage (I've only checked it twice in the last 6 months, but on 70mph trips we got just under 30mpg and 23 around town).
Love the car except for the cabin noise level on so many of our eroding and studded snow tire rutted concrete roads.

The NX is NOT fuel efficient or powerful and we all knew that before hand. Mine is rated 21/27 city/hw and the combined is 23 or 24 mpg. I am averaging at 24.2 mpg at 13630 miles. I think it achieved its goal.
It does have other problems, though.

It's all about managing expectations, if you have a lead foot you'll get lower mpg, drive in Eco you'll get more ( i avg 25-27 on eco). As for the OP, did they not state the EPA mileage on the sticker when you bought the car? Where did it not deliver on what it stated? Sounds like just another complainer comparing apples to oranges again. If the number of speeds in you auto and mpg is all that matters to the OP then i suggest you look elsewhere of the hybrid.

Thanks for all the positive and negative responses! I have been driving for 48 years, have owned and driven in excess of 70 vehicles an aggregate of almost 2 million miles.
I am not a lead foot and drive with the intent of safely moving with the traffic presented. Here in the North East, that means travelling at 75 mph when in freeway conditions.
I have never looked to the EPA for a fixed indicator of what gas mileage I may obtain. Most often my driving habits allow me to attain higher than "stated" values.
Our choice of the Lexus was not based solely on fuel economy. Comfort, back seat access, (lacking in many vehicles in this class), and reliability drove us to this choice.
All I was pointing out was that to date, based on experience with other vehicles in this class, the NX200T was not performing (yet) in the mileage department. I was totally aware of the 6 spd transmission, and while a negative in my opinion, did not change my purchase decision.
I was just pointing that with many options available, manufacturers have been moving to more gears, not less.

My 2017 NX200t FSport has almost 10K miles and it gets the worst gas mileage. I normally drive locally with a lot of stop and go traffic. I'm in the Northeast so it gets cold. I get roughly 200 miles per tank with a 16.7 MPG average using premium gas. I drive in ECO mode most of the time and am not a lead foot. Could something be wrong with my car?
