2020 RDX SH-AWD Very Low mpg

The RDX is just not some grocery getter. (Not that there’s anything wrong with that.)
You want an AWD car with torque-vectoring AWD, solid like little else, drives almost like a sports sedan, has all the modern driving aids, has very good (as opposed to acceptable, or great) power, hauls a ton of stuff, and has a great sound system and a sometimes workable Carplay/AA for a good price? The RDX stands alone.
You can pick a thing or two another one does better, sure, but the entire package? Nothing much short of 10K matches it.

Hello,
Purchased the RDX last month. Took it for a long drive in the thanksgiving weekends.
My fuel economy is pathetic.
Normally my drive is in city. No highway. There I am getting 15mpg.
On the road trip, the max I got was only 23mpg.
My friend's BMW X5 got 29 mpg, and he is more heavy footed than me.
This SUV is more gas guzzler than a F150 truck.
Sometimes I feel the older V6 with Cylinder De-activation would have given far better mpg figures.
I wanted to check my tire pressure.
Currently cold PSI is 33. Should I put in more to set it up to 35 psi in cold?
Also, Honda seriously made some wrong promises.....
This car is not "luxury"....it is just expensive. I drove the CX5, and they have the same HP and Torque when using regular fuel.
Mazda also mentions if using premium gas one would get 271 HP.
Which is exactly the same. And for 35k you get the top end CX5 with every bit of features built in.
Seriously feeling very bad buying this car.
Its not even 1000 miles and the rear tire trim has loosened. Will have to take it to the dealer.
And the dealers are ruthless as hell.

That's not accurate. The CX-5 makes 227 hp with regular and 250 HP with 93 octane.
Also, the engine is tuned differently. The 2.5 T of the CX-5 was designed for maximum low end power but loses steam at high rpms. The RDX has got a nice even distribution of power through most of the rpm range.
BTW, I also looked at and test drove the CX-5 with the 2.5 T engine myself, and considered it as an alternative to the RDX, but felt the rear legroom was inadequate (and the hump in the middle made it even worse), the stereo / infotainment / navi system wasn't as good, and felt the overall refinement and styling of the RDX is better than the CX-5.
One thing the CX-5 has that is missing on the RDX is the 40/20/40 split folding rear seats. I would love to have the 20 section in the middle so I could put the skis there instead of taking away the entire 40 section on the right with the RDX.

When I first got my 2019 RDX I was disappointed in the gas mileage as my 2017 RDX averaged around 26-27 MPG with a commute that's mostly highway. The same commute in the 2019 was 22-23. That was 30,000 miles ago. The 2019 is still averaging 22-23 in that commute, and now I am used to it. Would I be happier with 26-27? Sure. However, at this point, it does not bother me.
15 would bother me.

My new 2020 advance model with just over 1200 miles on it got 28.5 highway miles,comfort mode 300 mile road trip very pleased with that, also did a 200 mile road trip in sport mode and got 26 ish, comfort mode makes a difference or not perhaps. no complaints enjoy the ride..

SH-AWD here. Most of my driving miles are highway with occasional traffic / bumper-to-bumper, and around town suburban errands. Tankful to tankful, I average anywhere from 21 to 24 mpg (9-10 kmpl).
I'm in the middle of a 3-4 tankful test of regular (87) vs. premium (93) to see if and what the difference is. This will be for winter driving. I'll try the test again in the summer.

here, 25.1MPG for a 36mile commute to work. Only 30 miles are highway. Still on original oil. Given 26MPG rating for highway on sticker, what is there to complain about? I am getting what was promised. The milage will go up after you change oil and engine is more broken in. Maybe 2-3% more.

This engine seems to have an mpg sweet spot at 50 mph. Higher speed degrades the mileage considerably. I just returned from eight hours of highway driving averaging 70 mph. Mpg was 24 with hi test. At 50 mph, I can get in the low 30s. The 2nd gen sweet spot was at 65-75 mph with the VCM.

I get > 30 mpg at about 65 mph.

I drive my 2020 RDX SH- AWD bttween 20-45 mph mostly around the suburbs. Driven 1,479 miles and averaging 20.57 mpg. Driving from Atlanta to Tampa in February. First long distance on the interstate. Anxious to see what my mpg wlll be . I wont be going 50 mph I can assure you.
#59
What's a simple test I can do to see if the car is within the advertised mileage.
Fill the tank, reset trip meter, go on the highway and drive at 65mph for 25 miles then check average?

city driving is highly subjective area... in severe traffic your MPG can be 10MPG

Don't neglect the effect of ambient wind. Since wind resistance isn't linear, you don't get the same boost downwind as it costs you upwind. And cross-winds count too. It's probably tough to design a car that's aerodynamic with an effective wind direction at 45° to its direction of travel. Unless it looks like George Jetson's car. If a cross-wind causes the airflow over and around the car to become turbulent, all hell breaks loose.
So if you drive in a windy area, mileage tends to suffer.
Full disclosure: I used to race time trials on a bicycle. And my engine sucks.
But here's some more stuff to think about:

I am on an extended road trip, driving conservatively, which is between 7-10 mph over the speed limit. (It is my God-given right as a natural born American to do ten over on any highway. It is right there in the Constitution.). I am getting just a tad over 25 mpg.

For example, for a freight truck, it takes 57 hp to overcome wind resistance at 50 mph, but it takes 97 hp at 60 mph. Obviously, the RDX has a much smaller frontal surface area than a freight truck, but the take home message is that it takes much more power to overcome wind resitance with a slight increase in speed when you get above 40-50 mph.

Frontal wind resistance is one part of it. A bigger force that requires even more power to overcome is drag. Drag is the "vacuum" formed behind a vehicle as it cuts through the air. It actually has the effect of pulling the vehicle backwards. This is where aerodynamics play an even more prominent role than in the front. This is the reason for all the gradual sloping effects in the back, especially noticeable on highly fuel efficient cars, i.e. Prius, Insight, etc. Some large commercial trucks are also starting to add large rounded drag reducers attached to the back.

you expected 27MPG?

OK, I completed my trip, a bit over 1300 mostly highway miles, average 25.5 mpg, highest observed was 27 which was at 70mph on totally flat roads with the temperature in the mid 60s.

I normally get around 22 in everyday, suburban driving. Worse when it is cold.
