2017/18 MDX Hybrid MPG Thread
Please post your full tank of life time avg mpg here. I thought it'd be a good idea to gather real world mpg info on this new model.
If possible, please add city/highway mix, elevation change and your driving style in your daily commute.

Overall mpg for about 2,500 miles is 28.1 mpg. The best I can recall on a short trip of about 10 miles was 39.7 mpg. The worst was 26.7 mpg. It is easy to see a near constant 27 mpg when my wife drives the vehicle. When I drive it I generally average in the 30-32mpg range as I have more experience driving the hybrid drive system than my wife.

Most of the area near me has small elevation changes in the few hundred feet range at the most, more rolling hills. I tend to drive on the conservative side until an "opportunity" develops and giving it the beans is the "right" choice. I have been known to drive like a Hoonigan from time to time, but that gets expensive real quick. For the most part I almost never find the need to floor it and if needed it is only for a few seconds. In the RLX-Sport Hybrid, it is way faster from any speed and that requires serious respect of the "go peddle". Typically I drive like a limo driver would, thus the ability to produce mpg returns greater than the factory specs. It is easy to do and very repeatable in either hybrid vehicle. What I find amazing is that even cruising at 80+mph on the highway over long stretches, does not draw down the mpg by more than 1 mpg over driving at 70mph.

how do you get lifetime mpg?
I get 26+ on a 80/20 highway/city trip every week (130 miles). On freeway I am doing mostly 75 or more. Refreshingly odd to see mpg go UP when I exit freeway and go about 5 mile in city stop/go. MPG goes from 26.7 to 27.2
After I get home, it is mostly very short trips and mpg drops to ~25 without resetting trip computer.
That said I compared car computer to fillup and car computer seems to be a bit off
My manual calc was 23.5 for 400 miles and car computer said 24.1. That was the 130 mile trip (80/20) plus a number of very short trips.

Travels today produced 30.9 mpg for 191 miles and 474 miles remaining on the range to empty. At one point on the way home for the first 18 miles, 11.3 miles were in EV mode and averaged 39.8 mpg until I got to the highway. That overall trip home produced 32.5 mpg. So I got better mpg coming back than going out.

So Far
The vehicle tends to get around the advertised 27mpg. If there is more city driving it will dip down to ~26mpg. Only been 6 weeks and 1,000 miles so I hope that this will improve once the engine breaks in like it has on my other Acuras. No elevation changes or anything dramatically different about its regular use.

I don't get near your mpg, but I suspect that my highway miles are 75 to 80. Not that I'm disappointed. I'm happy with ~27 overall. Very short trips on the weekend brings it down to the 25 range, but to be expected.
I totally agree with the driving experience. It is the smoothest car I have ever driven and it is an SUV! The DCT is amazing and ICE on/off is seamless.

RLX- forgot to ask you what mode you use on the highway - I assume either Normal or Comfort.
I was under the impressions that Comfort does not change any settings that would impact mpg. I'm almost always in Normal on the highway

I agree totally. What a remarkable piece of engineering. It is hard to decide which sport hybrid to choose to drive. Don't cry for me. I'm very fortunate.

I don't mean to highjack the thread... But I am seriously looking into getting a Hybrid come this December.. Curious to see did you guys lease or finance? There are no good lease deals on the Hybrids at all right now...

I thought Comfort setting was just for the suspension? Does it also dial back throttle response?
#19
I thought of one other thing, I hope Acura can have the speed limit for the road we are on at any given time posted on the MID screen like Audi does. That would be helpful.
Oh and lastly, while in Turks, I noticed about every 10th car was an Acura TSX, except it was not an Acura, it was Honda branded as an Accord. Never saw that before. It must be the European model.

I had trip back from wine country today. Got a stretch of highway where I was always in the 60 to 65 mph range and hit 30+ mpg for the first time ever. I think 2K rpm and ~70 mph is the magic change point. After road opened up more and I was able to speed up to 75 mph, mpg eased down below 30 mpg and kept going down to settle at 27.5 mpg. I also changed from normal to comfort, but doubt that had anything to do with the mpg. The biggest issue at highway speed is wind drag and that increases with the square of your speed. Thus, going from 65 to 75 can have a significant change.

I was looking at the MDX. This is the reason why I really want this SUV later on. Such good gas mileage and power delivery and from what I hear the transmission and the ride is so much better. It seems like a better value compared to other brands. And I think it would make a good complement to my Acura ILX. When I say later on, I am thinking about getting it in 2019 before I leave for Europe in Germany for work.
#23
So here is something interesting: My wife is consistently averaging 26.9mpg in mixed highway/local driving with her driving style (not as smooth). When I drive the MDX-SH, I see 30+ mpg easily on the same roads and speeds. Thus driving style and experience utilizing the hybrid system provides better overall mpg performance on a given set of conditions. I maintain the transmission, suspension, air management and overall noise suppression are exceptional over the non-hybrid MDX, but I do wish the power delivery was more quirky. What I mean is the engineers have programmed out the unique driving feel the RLX-SH has in spades. It is still miles better than the non-hybrid variant of the MDX, but by comparison the RLX-SH feels alive with the throttle, and the MDX-SH feels more digital. Some might say that it is more refined with the new programing and I am sure the revised RLX-SH will have the same "new program", but I think that is a mistake. The very unique and varied throttle mapping one can enjoy with the RLX-SH is almost completely missing in the MDX-SH. It is still there, but suppressed. Here is an example: When at speed 30-50mph in the RLX-SH, you can apply the throttle lightly where you are getting immediate and more progressive EV thrust(very little ICE rpm change), or you can apply deeper throttle and get a combination of ICE/EV thrust, or apply even more throttle and get a single step down of the transmission, or even more than that and get a multiple transmission step down/slight pause and you take flight (exaggeration). I'm missing better descriptors to explain what I mean. All of what I just described is there with the MDX-SH but it is muted relative to the RLX-SH. Yes there is less overall hp/tq with the same weight, but the driving experience is clearly different between the two applications of the hybrid systems, both awesome.

Update:
This weekend with at least 90% highway driving in the 70mph range, mostly on cruise control and on generally level roads, loaded with 4 people and luggage, I saw 31.6 mpg overall for 665 miles driven and as of now I have 42 miles to empty on the tank as it sits in my driveway. 700+ miles potential range on one tank! WOW! Yes I did top the tank before departing. For a while it was averaging over 32 mpg until I hit some traffic.

Did my usual 130 mile trip on Tuesday. Went very light on the pedal, slow acceleration if I needed to.
Can not get close to your results, but I'm always 70+
Between 70 and 75, I can get 29, maybe 30
Above 75 to 78, I'm at 27 to 28

I think the magic speed is 70mph or less. I drove it about 60 miles today at 75+ mph and it averaged about 29.6mpg. So I bet if you drop your speed a little you can have the same mpg performance too. Give it a try next time and see what happens.
#30
Nah - I believe you. I don't want to make my trip longer
mpg goes down at roughly the square of the speed increase, so it can drop very fast

is that your full tank average or "momentary" mpg shown on the dash computer?

^This is the average displayed in dash computer. It shows instantaneous as well as average for the Trip.
Had interesting drive today which correlates what Blackbird is seeing. I was on my return 130 mile trip which I go different route which starts out on some County back roads.
Normally traffic is light and I can go 70+. Today got behind some slower cars and for first 15 miles I could only go 50 to 60. Trip computer showed 37/38 mpg!!! Total level, no downhill, but power monitor showed about 30% all EV. This included 4 full stops at stop signs/stop lights. I light footed the acceleration from stop.
Then I got to speed up to 70+ for the next 45 miles. So after 60 miles, average was down to 32 mpg.
Rest of trip was mostly 75 - 78 and average came down to 28 mpg.
That said, when I do manual calc at fill-up, trip computer is about 5% higher.

It seems that the sweet spot for the MDX Sport Hybrid is driving at about 45-55mph at that is where I see the best overall mpg. Prolonged stop and go isn't so hot but still better than a traditional MDX mpg, but if the traffic patterns only allow 45-55mph speeds, I can see mid 30's for mpg easily. My lifetime mpg is now at 28.9mpg and we are passing 5,000 miles on it. An interesting note is the oil register on the MID says that we are at 70%. I will not wait for it to say 0%, but I'll likely get the first oil changes at about 7,500 miles, unless anyone thinks that is a stupid thing to do.

a lifetime average of almost 29 mpg is incredible. and this comes from a battery size that is relatively small (lexus RX has 1.9 kwh whereas MDX has 1.2kwh).
as for the oil life, I don't change my oil until 10k miles have elapsed on my RX hybrid. Even then, the oil comes out rather clean. I think I know which vehicle i'm moving to when I'm done with my RX.

Here is an interesting tid-bit. If the new Lincoln Continental twin turbo is rated at 400hp and 400 ft/lbs tq, and its 0-60 and quarter mile times and speeds are the same or slower than the RLX-Sport Hybrid, that furthers the argument that the RLX-Sport Hybrid is significantly under-rated for power.
Continental
0-60 5.0 seconds (rated at 400hp/400tq)
13.5 seconds @ qtr mile @ 106mph
RLX Sport Hybrid (rated at 377hp/341tq)
0-60 4.88 seconds
13.6 seconds @ qtr mile @ 106mph
#36
Do you know what the 0-60 is in the MDX hybrid?
The ones I saw were higher than I thought it would be. I think they were just over 6 seconds

C&D clocked it at 5.7 sec. the rolling start, which, I think, is more important was 6.1 sec. this compares to 2016 Land Rover Range Rover SV Autobiography's rolling start time of 5.8 seconds...... very very close to a car that costs 2 times the price. Also 2016 Lincoln Navigator L 4x4 did that in 7.2 sec's and 2017 Cadillac Escalade did it in 6.3 sec's. Infiniti QX 80 was also slower clocking in at 6.4 seconds. Audi Q7 = 6.4; BMW X5 = 6.8 (turbo lag); Rang Rover HSE= 6.5 sec's even with a supercharger. Finally, the mighty 2017 Mercedes-Benz GLS450 4MATIC had similar results at 6.3 seconds to 60 mph with a rolling start.
Rolling start is a much better measure. It accounts for things like turbo lag (if there is any), throttle response, and won't let you brake torque. it's just mashing the pedal like in a real emergency situation. As you can see, except for the cars costing twice the amount and guzzling almost twice the gas, the MDX hybrid doesn't have a competition. Shamefully, my own 2013 RX 450h is awfully behind at 7.1 seconds. If you are looking for the maximum amount of torque at the earliest part of your pedal travel (most torque figures are understated from Japanese makers) MDX is your car.

Not all modern turbos have the problem, however. The Edge Sport logged the following times in C/D testing: 0-60 in 5.6 seconds, 5-60 in 6.1 seconds, and 50-70 in 4.1 seconds. The 2.7L turbo is an impressive piece of engineering. And it runs just fine on regular unleaded.

I drove a lot of local stuff today with many short 5-7 mile segments, all under 50mph. I filled up last night so today was all fresh miles on the gas tank. So far I am averaging 34.6mpg after 66 miles today on this tank. That is fantastic for an SUV. My best one way trip was 48.2 mpg but that was only about a 4 mile trip before I stopped. So far the lifetime average after 6,000 miles is 29.4 mpg. When I drive it I consistently get over 30 mpg in all forms of driving. When my wife is behind the wheel she gets 26-27 mpg.
