37+ mpg in a 2014 Honda Odyssey



I recently had to pick up some friends from Ohare airport in Chicago. I'm just north of Milwaukee, and I took their 2014 Honda Odyssey which is identical to the picture above. I had filled it up before heading out, so I reset the tank average. As I set out, I was very surprised as the average...

JUST





KEPT





INCREASING

It finally peaked at 37.1 before I got stuck in traffic right around the airport.





Upon bragging to Darin, he mentioned what I had suspected. That version of the Odyssey does in fact have cylinder deactivation. In the pictures, you can see the ECO light. Whenever that was on, the mileage took a good jump up. The great thing was that I basically just set the cruise control at the speed limit and it did the rest. The cruise did a great job of keeping it in eco mode. It would allow the speed to drift a bit more than most cruise controls I've seen.

I'm impressed. Kudos to Honda!

Toyota and Honda seem to have done an exceptional job at maximizing fuel efficiency in their minivans. About a week and half ago I drove 3 hours on the highway in my family's minivan averaging no less than 5 mph below the speed limit and no more than the speed limit, and coasting just a little, and averaged 32.5 MPG for the whole trip with probably a thousand pounds worth of weight from passengers and luggage. It did get up to 33.1 MPG before we exited the interstate and all the weight killed MPG in stop-n-go traffic where we "only" averaged mid to upper 20s MPG.

Our van ('04 Toyota Sienna) is only rated at 25 MPG highway compared to the 28 MPG that the Odyssey is (I think the new Pacifica is rated the same as the Odyssey)? Beats me how Fuelly says the average minivan driver gets only 18-20 MPG....does this mean a 40 MPG minivan is possible with hypermiling and ecomodding?

Well, I can say for sure the owners of the van never get anywhere near that. When I drove it home for them, they had averaged 22 mpg with it before I filled it up.

I'd say at modest speeds, 40+ is possible even without mods. My traveling was probably half at around 55 mph and the rest was 65-70 mph. It was at night though, very little traffic (no slow downs). If it were all at 45 mph, I'd have gotten 40 mpg no problem.

Great numbers!

I tend to drive faster when in a van simply because it's not just my time that is being wasted. With a carload of people, I'm traveling at the fastest safe speed I can while trying to stay below the attention of patrolmen.

How?? It used to be so much easier to beat the EPA numbers in the minivan than in was in my Civic before I finally "mastered" it's best eco driving style.

If only the Civic had cylinder deactivation.

Minivans can surprise you big time. I drove from Carlisle, PA to Washington, DC a while back in the wife's '14 Chrysler Town and Country. I set the cruise to the speed limit, mostly 55 with some 65, cranked the AC and with the family in it, the FCD claimed somewhere around 35mpg. I was pretty stunned.

Last week we did a 1000 mile trip in our 2011 Town and Country recently, Missoula to Seattle and back at 5mph over the speed limit, so 70-85 mph and got 24.3 mpg. That is A/C running, cruise set, 3 mountain passes, and plenty of construction zones. The overhead was reading higher, even 28 for one run, but I figured that was off. We have done 500 miles and averaged 29.5 pump caculated at a more reasonable 60-65 in the past. I have no doubt the more modern Pacifica with lighter weight, better 3.6, more gears, and better aero would do 40 mpg if you kept it under 60.
My LRR tires are on their last summer probably and I have 75k miles now. It really seems to have improved from when we first bought it used with new tires and about 25k on it. Even day to day city it gets 18-19.

(I’m not going to pull punches, here)

Time being wasted?

1) What’s the percentage change in total braking distance from solo for the fully-loaded van?

2) And, from lower speed to higher? Each iteration. (What was the tire pressure change required?).

Consequently, what is the minimum highway spacing distance requirement in any of these?

You know none of this, do you? Consider your “skill” (ha!) somehow above reproach. Without this beginning, you don’t know “safe”.

Your premise of time-wasted is a giant self-deceit.

As was said long ago, “You know neither the hour nor the day”. (Understand this and the rest isn’t necessary).

And the same for all others who find auto travel a burden. To, get it over with as fast as possible. Who thereby make a mockery of shared responsibility with every demonstration.

You want it in Eco Modder terms? How many highway braking or deceleration events after entering, but before exiting?

“Travel speed” is the province of fools. Traffic volume dictates travel speed as surely as the sun rises in the East. The upper limit is constantly in modification according to it and other factors, equally-weighty. (Which should have been appreciation of tire slip angle and lateral acceleration; no van is capable of much while solo; but loaded?)

I’m all in favor of the use of cruise control. In which, how often did you cancel cruise control to get someone passing around you more quickly; that they could return to the travel lane 200’ or more ahead and thereby all avoid pack formation near your vehicle?

Was there ever a time you were surrounded by vehicles fore & art? To port & starboard?

Count yourself a terrible driver if this was avoidable in any sense whatsoever. The definition not only fits, it is statistically-valid.

The premise to travel is to arrive in the same shape as when departing. How that is achieved is the task. Driving for FE is a subset. It is finesse.

That finesses is the cruise control set speed most appropriate to elimination of braking events. and minimization of CC cancellation all while maintaining never less than 200’ of spacing (goal of 600’).

You, and others like you, have a long ways to go in becoming able to drive economically, as you haven’t first made a study of, much less mastered, “safe”.

I see your type daily. Never an understanding that what is overtaking in the mirrors counts for more than what is out ahead. A bright 12-year old can be taught the latter. But we’ve imported millions incapable of abstract reasoning, thus incapable of deducing the former. (Which is before visuo-spatial skill).

No one cares about your self-regard (self deceit) nor about the absence of negatives (citations, accidents, etc; same pride exists with those who’ve avoided arrest and prison sentence), but only about how well you are managing (making decisions about) what is happening around you, and how well that is being done.

Others far better than you are constantly having to take your selfishness into consideration of their own actions. But you believe (act the Fool) that your faster travel rate merits you (guffaw) special consideration.

Got news for you: The passing lane confers no ROW. None, except in the short moment of a pass. Never in overtaking. Also, one cannot block access to the passing lane (this list continues long and pitifully).

The day those better drivers don’t extend that allowance for your bad manners may be your last. Or, far worse, for one of those passengers. Perhaps that death is preferable to quadriplegia, as no long years of suffering ensue. Works better with Civil juries, that much is true.

Accidents aren’t accidental. Nor do they have single cause. So start by shoring up the timbers.

I’m appalled that EM is apparently, “engaging in the same unconscious bad behaviors, but for a lower out-of-pocket expense”. (The owner/moderator will be proud). But maybe not surprised at the fanboys around here of the electric car debacle unfolding at present whereby tech (Big Brother) is the only one accountable.

“Be a man” has become an exhortation without an echo.
