Post actual MPG on your new RDX
What MPG have you been getting on your 2019 RDX? Reports have been coming in much less than the sticker is showing. Please add your experience (MPG / driving mode/ and MPH, etc.) This could be a great fact finding thread. Thanks.
The estimated mpg shown on stickers varies for FWD:
Fuel Economy Est-Combined (MPG)24 (Est)
EPA Fuel Economy Est - City (MPG)22 (Est)
EPA Fuel Economy Est - Hwy (MPG)28 (Est)
The estimated MPG for AWD is:
Fuel Economy Est-Combined (MPG)24 (Est)
EPA Fuel Economy Est - City (MPG)22 (Est)
EPA Fuel Economy Est - Hwy (MPG)28 (Est)

11.1 but haven’t really left a 10 mile radius of my house in the first 4 days of ownership. I have a full week of work travel coming so I’ll know after this week what a full tank will do.

I wonder if elevation has anything to do with the variance in mpg...
I started this thread because we're planning to get an Advance Sh-Awd as soon as one becomes available in the color we want in our area. The Sh-Awd seems to be a rarity here (in Texas). Kinda weird since our hill country roads which are heavily populated with wineries and hills (albeit a mini version) are as winding and fun to drive on as those beautiful mountain roads in Central California (grew up there).

on it, that's not bad. When I drive it, which hasn't been much, I can watch the on board computer for fuel mileage start dropping! LOL! Gee, I wonder if it's my heavy foot? Oh yeah, This thing is quick and fun to drive.
The fuel mileage at 20.1 was figured doing the math, not looking at what the computer says. It's been about .4 lower.
Fuel mileage in town just might equal what our Gen 2's got, which was a consistent 22 mpg. But, the '19 RDX will NOT get the well over 30+ I got with the V6's. It's just the nature of the beast with this 272 hp, turbo 4.
So, fuel mileage average will not be what my V6's got. Always makes me wonder WHY...why Acura did you go to this engine?? Certainly can't claim better economy...although they seem to want to use those words....if
you have been a long time owner of Gen 2 RDX's....and I've had 3, then we know the truth.

I am curious what some are getting who do mainly city driving. I do 95% city driving and have gotten around 15.5 MPG on my 2010 MDX which was rated 16 for the city. I am hoping to get at least 20 MPG on the new RDX.

I've been getting 18.5 around town and 25.5 on the highway at 75 mph.
Using 93 octane and Comfort mode in SH-AWD Tech model.
Hopefully there will be some small improvement when the car is fully broken in.

This is very useful for those of us considering the RDX....I am looking at the A-SPEC RDX w/SH-AWD
I have about a 100 mile daily commute on mostly highway and would love to at least come close to matching my TL MPG which usually about 26 mpg at each fill up. The official ratings for my 07 TL are 18 city/26 highway/ 21 combined.
I am hopeful that the numbers will improve as the engines break in and the mileages of owners increase.

Catbert430 brings up a very relevant point - it would also help to know what octane gas you’re using...regular or premium. So, great information to share is:
Which RDX model (Advance, A-Spec, Tech, Base)
And how many miles you have on it
FWD or AWD
driving mode (Comfort, Sport, Sport+)
city or highway ( or avg % of each)
type fuel
mpg
Thankyou all for continuing to contribute.

I agree with TxLady, it would be nice if people included the fuel type used (87 or 91 or 93) when they specify their fuel economy.
I would also note that I was pleasantly surprised when I was at a local Acura dealership and looking over the new 2019 RDX and popped open the gas filler door and what was inscribed was something like "premium fuel recommended", which to me implies it is safe to use 87, since it also said something like "87 octane minimum".
I wish I took a photo of that wording on the back of the gas filler door; if someone has a photo, perhaps they can share it with all of us. Thanks.

There was a thread (in the many 2019 RDX threads now active) which had a very lengthy discussion on this topic. (I can't recall which thread it was.) It seems many felt the turbos could be impacted in a negative way by long term use of the lower octane fuel. The higher octane would provide a higher mpg, better performance; and, longevity without issues. I'm no mechanic (by a long shot!) But a couple of the contributors said they had experience with turbos and were pretty adamant about their feelings on the topic.
Just mentioning this so if you want to do a search on the forum for the conversation...it might answer some of your questions.

The fuel filler door does say something along the lines of 91 recommended, 87 minimum. I can try to upload a photo later.
I’m now on my 3rd tank of gas (including the gas from delivery)/ 1,400 miles. The past few days my mileage has ranged from 20-20.5 MPG in Sport on my SH-AWD A-Spec. I only use 91 from Chevron or Shell. The MPG has gradually been increasing so I’m hoping it’ll go up even more with a few theousand miles on it. This weekend I’ll be taking the RDX on my second trip to the Bay Area. First time I drove there I had about 500 miles and only averaged 20 MPG

to teach internal combustion engines, turbine engines, and diesels.....turbo types too.
The problem is enhanced during much hotter operating climates and when towing. So, I've always used Premium fuel.....in my Gen 2 RDX's...personal choice there....and I will always use Premium in my '19 RDX. Just a smarter move with this engine.
I know I will get push back from some....but, what I stated is just the facts....and even though Acura wrote the same "warning" with the 3.5 V6's......it's even more imperative to use Premium with these turbo 4's.
If you use 87 octane, then you will just have to "baby your driving technique" a lot more. But, again, in really hot weather and or towing, you better be using 91. JMPO.....FWIW

Jeez, if yalls are getting around 20 mpg in comfort mode, a guy like me, who really only drives in Sport and likes to make the drive an adventure, is probably only going to get 16-18 mpg using 91 going about 80 mph on the freeways, 60 mph locally. Hmm..
