My friend from Honda emailed me and said there is no software updates to improve the MPG.

He mention listed MPG depends on driving condtions and MPG is usually done under controlled circumstances and is the best a car can get.
Driving with heavy foot will make the MPG worst as he quoted.

We have a second generation MDX with AWD i.e. not hybrid. (Not available on the prior generation). I get about 17-18 MPG in combined real world driving. I was leaning towards the naturally aspirated internal combustion engine (ICE) third generation MDX as a replacement but now that I've read the driving reviews of the Hybrid, I'm probably leaning toward the Hybrid. For instance, most reviewers find the Hybrid has better 0-60 MPH Clock times than the non-Hybrid which surprised me because the non-Hybrid ICE version has a larger engine and the Non-Hybrid weighs less. The electric motors must really add a lot of low end torque. And torque vectoring is a real thing. So I'll probably be willing to give up the ability to tow to get better driving dynamics and better gas mileage. I've also gotten familiar with Acura's Sport Hybrid technology in our 2016 RLX and it works great.

At $3 per gallon, the difference between 17.5 MPG and 22.5 MPG over 75,000 miles of driving is about $2857. Wiith gas prices lower than $3 the savings is even less. But it means that the $1500 price upgrade from an Advance SHAWD with ICE to and Advance Hybrid SHAWD is a pretty good trade. If the Hybrid gets 27 MPG then the savings really adds up. With same assumptions (75,000 miles and $3/ gallon) I would expect to save about $4500 at 27 MpG versus the 17.5 I get now.

But it I may wait a few years to see if they'll stick the larger engine from the non-Hybrid into the Hybrid. Id like to have the extra performance, even is an SUV.

RLX-Sport Hybrid

Dude, don't wait to get it. We love it and you will too. The driving experience is amazingly different and way better than the the ICE only MDX. We saw a mpg increase from the old MDX with the 9 speed transmission with 20mpg in everyday driving to 29.6-30.2 mpg on average in the MDX-Sport Hybrid. I am seeing better mpg than Getakey as I think the roads I drive on and my normal driving style is such that the 2.5 years of experience driving the RLX-Sport Hybrid has helped me produce better results. Don't drive it though unless you are ready to buy it. When I drove the ICE only MDX recently while a recall was done, the ICE only MDX seemed almost coarse and primitive compared to the MDX-Sport Hybrid. Trust me and Getakey, you will love the experience.

I am a new member here ,Have been on the BMW forums for years, but have had Honda Mini Van (2001 and 2005) 2009 MDX and 2 Honda Pilots (2012 and 2016) as well. I now have a 2017 MDX Tech Sh-Awd. Currently has 1300 miles and owned about 3 weeks. I am getting much better mileage than all of you, I don't know why but I won't complain. Last weekend took my daughter back to college. Drove 425 miles in one day. Normally a 4.5 hour trip took 6 hours going and 5 coming back due to heavy traffic in the Bronx and George Washington Bridge. Used cruise when possible at 65 and got 30.5 mpg for the whole trip. Also did trip to see a school this week in Conn. for my other daughter very little traffic at about 65 mph and got 29.5 round trip. These numbers were very close to the 2016 Pilot which was totaled recently and thats why we went to an MDx in such a short time after getting the Pilot. I only use BP Premium when available and don't driver like a crazy person. Just my 2 cents.

My 2017 MDX SH-AWD Tech gets about 19 MPH around town. Lot's of 40-45 MPH driving in my part of town. On a recent 200 mile trip on I15 I got 26.5 going and 29.4 coming at 75 MPH. My tires are at 35 PSI.

I am getting 19.4 mpg mixed, is this average? I have 500miles since purchased date, I am expecting at least 25mpg of mix driving.

Keep in mind, at 500 miles your engine is far from being broken in. Most engines these days take at least 20,000 miles to be more or less broken in before they achieve their peak fuel economy; some even longer.

FWIW, we bought a minivan back in 1998 and took it on a trip a week or so later; highway mileage was a pretty consistent 18 mpg. Ten years and 150,000 miles later the van was easily able to get 24 to 25 mpg on the highway, and even got 28 on one long trip.

So here's a comparison of 3 different Acura SUV's, similar driving patterns (mix in-town and rural driving, some highway but not much), MPG observations:

2013 MDX SH-AWD - typical MPG's of 17-18 during the first 1-2K miles, then up to 19-20 after broken in. If I got over 20 mpg for a tank it was definitely the exception - best highway MPG I ever got was 23.

2015 RDX AWD - typical MPG's of 22-23 during the first 1-2K miles, then up to 23-24 after broken in. Highway trips I'd easily get 27-28, but around town it settled back to the 23-24 range over 25K miles

2017 MDX SH-AWD - typical MPG's of 20-22 during the first 550 miles.....

So if you look at this progression, the '17 MDX is falling in between the RDX and the 2nd gen MDX I had - apples-to-apples driving situations. One of the reasons I dumped the '13 MDX was due tot he crappy MPG's, and I was happy with what the RDX gave me in that area - but felt it was lacking in space and AWD behavior. So far I'm happy with where the new MDX is starting. Haven't really driven any highway beyond 5 miles or so - and I'd expect mid 20's average in that regard...

Did you take a bath every time you traded in a 2 yr old SUV?
No but we had a similar experience with our 2011 MDX which we dumped after the horrible MPG. My best was 21 mpg on Hwy and regularly got 17 mpg pottering around town on Premium (yeeesh). Our 2017 w AWD has about 1400 miles and our mpg numbers are decent - 22.8 mpg overall. Regularly shows 19-21 mpg around town, 24-26 mpg easy on the Hwy.
don't drive aggressively in the suburbs - not worth it. We like how ours has started with the engine yet to be broken in...

Nope - leases with little down each time, and the dealer helping us move out with almost no cash. The MDX actually had me in an equity position when I swapped it for the RDX at the 25th month. The RDX was pretty flat at the 30 month point. So no baths - but I do lease......
