only the hybrid will do this:
was driving on freeway 70 - 75 for 90 miles with 28.3 mpg. Hit stop and go traffic jam for 5 miles. mpg went up to 29.2. Then got off freeway on city streets and mpg continued up to 29.5

Ha ha -last week 62 mile trip from Westchester to Long Island took 3 hours-I averaged 31.6 mpg and joked when I got home that with this mpg it is almost better to be in heavy traffic !!!

Very impressive! My wife asks me daily when the '18's are going to show so she can get her hands on one. Will be her daily driver.

Believe me she (and you) will really enjoy this vehicle. It is an awesome driving experience !!

How is the MPG during this current cold spell? I know it's gonna take a hit but how much for those of you in the below freezing temperature area?

I'm seeing the bigger change in city driving in my Hybrid, not so much on highway driving. I think my city average is now 23 to 24 vs a steady 26 city in warmer weather. The Hybrid heats the car from the ICE so the computers limit the EV until things get warm in the car. I now set the temp to AUTO 71' which helps to get a little more EV time. Overall it's great MPG for what is a very large, very luxurious, and high performance SUV.

mellonc

You are seeing sub freezing temps in SoCal?

GrebRL

Currently at winter domicile, Park City Utah, where the MDX is loving the snow packed roads. So far it performs better than my Subaru, but the newer tires are partly responsible. Our Summer domicile is Temecula CA. Yes, I know I've got the snow bird thing backwards but that's the way I like it.

mellonc

wow, that is impressive MPG for park city Utah. You've got both high elevation and cold temps. (traversing hilly terrain and in cold temps pretty much kill my mpg in the Lexus RX)

Anyone reporting avg mpg below 23mpg in mixed city/highway driving?

getakey

a few times my ave would drop to about 21 mpg if I had a lot of very short trips (<2 miles) on the back end of a highway trip

bmoua15

Mixed driving with a average of 26-27mpg when my foot isn't too heavy haha. In Sport + mode I still average 20-23mpg which is pretty solid in my book! Alot of people underestimate what this car really is.

RLX-Sport Hybrid

I just drove to Boston and back to Westchester, NY in the last week (two trips). One trip with the Blackbird and one in the MDX Sport Hybrid. Traffic was nearly identical for both trips, and I tried to drive exactly the same speed and manner to try to see which vehicle produced better real world mpg numbers. In other words I drove as gently as possible. Results for 385 highway miles round trip for each session: RLX Sport Hybrid = 32.7mpg, MDX Sport Hybrid = 30.8 mpg. In local trips I can easily see 38-42 mpg in the RLX and 34-38 mpg in the MDX for comparative reasons. However the overall range in the MDX Sport Hybrid with the larger gas tank approaches 700 miles if you top off the tank when filling it. When I got back from Boston in the MDX Sport Hybrid the range to empty was displaying 345 miles to go. The RLX Sport Hybrid showed 255 miles to empty.

mellonc

what was your average speed (overall including local)?

RLX-Sport Hybrid

For those trips 68mph and 67mph. It was just a few miles of local driving for each round trip.

JTC1

Not sure my man math agrees - not sure how we can get 700 miles out of a 19.4 gallon tank event at 30.5 mpg.

lsulaker

You are correct. The math doesnt add up. The best that I have gotten is 32.2 actual MPG, not computer based MPG. 32.2 x 19 gallons = 611 miles. Good luck getting over 600 miles though. I just wouldnt risk running my tank that low.

RLX-Sport Hybrid

You can fit another 3.2 gallons if you slowly add gas after the initial cut off. I know that is not good to do, but doing it occasionally has never created a problem for me in any car I have owned over the last 30 years.

I'm owned a 2007 and 2013 MDX. Currently have an Audi S5 convertible for the warm months(May-Oct). Looking hard at a 2018 Certified Sport Hybrid Advanced. BUT, I do mostly Highway miles, and I live in New England. So since the MDX Hybrid would be mostly driven in the cool/cold months, I'm wondering if it makes sense to pay what is roughly $7k more vs. a 2018 MDX Tech. Any more feedback on this mpg in the winters Is appreciated. I read somewhere on the forum that at Highway speeds the added weight of the battery offsets and makes the mpg lower than the non-hybrid. Also, when idling in a parking lot, is the ICE running things or the battery?

bmoua15

The Hybrid Advance has many more advantages compared to a awd tech. The dual clutch is the #1 reason in my book

The MPG rating if any would be 1-2mpg difference between the two models but that depends on how heavy your foot is.

getakey

disadvantage of the DCT is that you cannot tow
smooth as heck though

lsulaker

As much as I love my sport hybrid, I am not sure that it makes much sense for you. Its real advantage is during city driving. In addition, the battery has to warm up before it can power the car. The engine is used to warm it up. In cold months, it takes longer for this to happen. I would estimate that it takes a few minutes minimum for the car to be powered alone by the batteries. If you are driving on the interstate, I am sure your trips are more than 5 minutes, so it would be warmed up, but the battery alone cant power the car over 55 mph.

On the other hand, the sport hybrid is the sportiest MDX that you can buy and something tells me that you would end up liking the way it drives and possibly end up driving it a bit more in the summer months than you expected. That S5 is pretty hard to pass up driving though!

mellonc

just checking on the MPG's during this frigid temps in the mid west. anyone have stats from locales where you didn't even go above freezing?

Leoskeys

mellonc

We have another hybrid in the family. That car went from 25.5mpg to 23.5 mpg when we went to the mountains (in Southern CA you have to get to higher elevation to get freezing temps). Looks like MDS Hybrid isn't so affected by the change in temps.

lsulaker

I have definitely seen a reduction in mileage. Basically, the batteries wont power the vehicle until the engine is completely warmed up. In the winter, it takes far longer for the engine to warm up which takes longer for the batteries to take over powering the vehicle. I have seen my read world MPG go down from just over 30 to just under 28 and Im confident it is because the extra 3 or 4 minutes that the vehicle is warming up and not using the battery. Im just in Louisiana too where it doesnt even get that cold but this happens whenever the temperature is below 50 degrees and I havent driven in a few hours. Everything else is the same- same trips and I dont use the heater in the car and dont use the seat heaters. I get aggravated every time I see the battery meter full but my engine is still running at a red light from it not being warmed up!

fongy604

so what are you guys getting on a full tank of gas.. currently got a 14 mdx.. get around 370-400 miles on a full tank... debating if its worth the upgrade...

lsulaker

I have gotten 470 mile on a tank (cold temps and more highway miles) up to 530 or so (more city driving and warmer temps). I think 450 is easy even with more aggressive driving. I have never put over 18.1 gallons in my tank and it holds just over 19 so its not like I am draining it completely empty either.

bmoua15

Driving dynamics alone is worth the upgrade. I average 350-400 but I have a heavy foot around town and always drive a consistent 80mph on freeways. I can say I've done 450 miles on one tank but thats being easy on the pedal.

ZinCO

New 2019 owner here... I only have 750 miles on the odometer, but I've never gotten more than 21mpg (all city driving) in the 2 months I've owned it. It's been very cold and I am at 5000ft, but the car does get a chance to warm up and does go into EV mode. In fact I generally see EV miles at about 25% of the total. Is it just too early for me to be worried about it? Should I expect it to get better as either the weather warms up or the car breaks in?

getakey

EV at 25% of total is very high. I'm usually at less than 10%, but get 27/28 mpg

RLX-Sport Hybrid

From April to November when it is warmer, I see 26-28mpg per tank in mixed driving. On a trip typically I see 29-30mpg most of the time. I have gone more than 600 miles on a tank many times. Yes I know what the tank size is, but typically I top off the fuel before a trip to give me extra range. In the winter I see 22-24 mpg per tank. My previous MDX was in the 17mpg range for winter local driving and highway was around 25-26 mpg regardless of winter or summer driving.

TSX69

I noticed that these past few months on cold days (30-40 degrees), my MDX Sport Hybrid was getting 23-25mpg going to & from work. However, on the days when the weather was warmer (60-70 degrees) the mileage goes up to 29-31mpg on the same path. It is worth noting that on the warmer days it goes into full-electric mode much sooner & more often. Too bad it cannot get the higher MPGs no matter what the weather but it looks like it the annual average should even out to the advertised 27mpg (perhaps a bit higher since we have more warm days here than cold).

Dennis Wu

New owner of a hybrid. First tank I got 21 mpg, 2nd tank 20. I drive 50/50 city / highway. I do live on a hilly area. The mpg is lower than I was hoping for but i guess it makes sense because when i drove a non hybrid loaner, i got about 15.5 mpg. Hoping that it gets better over time to mid 20s.

steameng8

I only have about 3,800 miles on my 2018 MDX Adv Hybrid. If I drive easy around town, I get about 25-26 MPG . If I get in a hurry I get about 23 MPG. Highway mileage has been 29-31. My 2014 MDX Adv would get about 17-18 MPG in town and about 28 MGP on the highway. I still enjoy the drive every time I get into the car. It has never been in the shop since I picked it up on April 19, 2018. It is by far the best MDX I have had since my 2001, 2004, 2008, & 2014 MDX.

mrgold35

Does everyone only use premium (90-93), mid-grade (88-89), or regular( 87 or lower)? Notice any difference between the grades if you switch it up? I usually get my fuel from Sam's or Costco and they don't carry mid-grade. It used to be a .08-.10 cent difference between reg to premium. Now, .40-.70 cents seems to be the normal spread. That would be +$400 savings at my yearly mileage of +20,000 if reg is .50 cents cheaper with zero-minimal drop in range/performance.

moose66

Premium only in both of my Acura's. I'm sure this has been covered/debated on a thread somewhere here. If I can recall, it was said you may notice a slight decrease in both MPG and acceleration with lower octane fuel.

flyboy

I use Premium and usually ethanol free Premium. Today I traveled 480 miles mostly at 60 to 75 mph, average was 28.9. If I stay below 55 I can get 32+ on a 22 mile daily commute with minimal traffic and only two stop lights. 2017 MDX Hybrid, tires at 36 psi all around. If I averaged the trip with speeds 65 and less it was closer to 29.5, over 75 26 to 27 is more of a norm.

ceb

remember that at your altitude 85 is 87 and 87 is 90/91
