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.

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.

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)

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

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.

Just got 30.1 on my last tank. That’s real MPG- the computer said I got 32.3.

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.

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

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.

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.

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?

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.

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!

Winter MPG in New Hampshire

i live in NH, and drive a lot, and all over Northern New England where often temps hit zero. I put my 2019 Tech Hybrid into use around Nov 1.
I have driven 8,880 miles, and MPG is roughly 26mpg, Which is probably 70% highway. Iím happy, especially because my 2013 MDX averaged about 21mpg over the course of 160k miles.

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.

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!
