What is the "Econ" button for?

When you push the "Econ" button, what exactly does it do?

From the manual:

The ECON button turns the ECON mode on and off.

The ECON mode helps you improve your fuel economy by adjusting the
performance of the engine, transmission, heating and cooling system/climate
control system, and cruise control.

In my experience, it works fairly well, although the car can still be babied to exceed the window sticker mileage (at least as indicated on the slightly optimistic in-car display).

To give an idea, I took a road trip this weekend from the Cental Valley of California to the North Bay Area coast, about 120 miles each way, similar driving conditions there and back. On way there, Econ off, my indicated mileage was around 39-40 mpg. On the way back with Econ on, I made it home with an indicated 42 mpg.

My measured MPG is actually higher than the computer which is uncommon on most cars. I have hit 40+ on a 70 mile round trip with econ on. Did not test off. Ill be doing a 750 mile trip in 3 days-expect a full review post haste.

Sorry--I haven't added my signature yet with all the particulars.

EX I4 CVT, Modern Steel Metallic. About 2/3 on major freeways, 65-72 mph, mostly going with the flow of traffic. The other 1/3 was 2-lane highways, rolling hills, 45-55 mph.

10 days in, 800 miles already. The day I got her...

The manual (or my sales guy - I forget which) says you should get a 5% boost in MPG with the econ button on.

I've been driving with it on all the time the past few weeks - the only thing I really notice is a sluggish feel when I start from a total stop. If you romp on the gas when it's on the car ignores the whole econ business and gives you what you need.

The V6 I tested there was quite a bit of difference in power between the two modes. ECO was very sluggish. Not un-driveable, just doing what it is intended to do.

From what I understand, it also dials back the A/C operation. So in the summer time or in high temps, you may not get the most effective cooling that you desire.

I remember when Honda and Toyota dealer installed A/C systems (until the mid-80s few Hondas and Toyotas had A/C built into the cars at the factory) completely shut off when you were at idle at a red light. If you had a stick it was good because you could keep the revs up a little to keep the A/C going, because if it was a terribly hot day and the light was long, you'd start getting toasty after 15-20 seconds if you didn't keep the revs up.

I'm sure the ECO mode on today's cars doesn't go that drastically with the A/C, but you may notice a difference.

We all have the econ button all you have to do is accelerate smoothly with low RPM's.

My question as well....and as far as I can tell it has not been answered.

What **exactly** does it do.....as in what sensors are utilized....that sort of thing.

So far....I have not come across anything beyond "it changes settings" etc.

I've left ECON on all the time, it dulls throttle response some but it's not too bad. The car still will jump if you hit it.

I've been averaging 27mpg 60/40 city/highway and I have 500 miles on an EX-L CVT.

Here is a good example of how ECO works.

Drive up a hill with ECO off and maintain throttle position. With the CVT, the gearing changes as you go up the hill to increase power.

Drive up the same hill with ECO on and maintain throttle position. With the CVT, the gearing changes very little and feels sluggish going uphill.

With ECO on, as others have said, the throttle response is dumbed down. The transmission is less aggressive and less likely to change with road conditions. A/C system is also dialed back if in use.

Short answer....messes up drivability, big time.

Longer answer....changes shift points, throttle response, etc in theoretical search for max fuel economy while messing up drivability, big time.
