When I took delivery of my 2013 RX450h, I turned the ECO setting on. I was happy with the fuel economy, but was disappointed in the engine's response and the performance of the A/C. I always kept the ECO setting on with my previous Lexus, a 2010 LS460, but on occasion when I turned it off on the LS, I only felt a small difference.
Well today, I turned the ECO setting off on my RX and WOW, what a major difference. With the ECO setting on, I practically had to floor the accelerator to keep up with traffic and it still felt sluggish. I also had to keep lowering the A/C temp, especially in town. Now, with the ECO setting off, the truck feels like it has a transplanted V8 from my LS. It seems easier to get up to speed in order to back off the accelerator to shut down the ICE. I just filled the tank so I'll check the effect on fuel economy with the ECO setting turned off. Hopefully I'll still be able to restrain my right foot.
I had a smile on my face driving my RX before, but now I'm LOL.

I've seldom used mine on ECO during the last couple of years. My MPG is great mostly because I still use the engine monitor to drive as economically as possible. But I have the power when needed

What kind of MPG are y'all getting with ECO off? I've been driving 100% ECO the past 18 months, but only averaging 29 MPG (mixed City/Hwy). Now, I'm thinking WTF, might as well turn off the ECO and have some power at hand when I need it! When I first got my RX450h (2 yrs ago) I managed only 25-26 MPG with ECO off, but that was before it was fully broken in. If you are all getting over 28, I'll give it a whirl again!

I've been slowly going through the threads in the Hybrid section to learn more about this complex machine. You guys have posted a lot of great information. Thanks for sharing your experience.

It's definitely a driving style and you have to be consistent not just part of the time. Planning your route and stops, coasting to stops when possible rather than stopping when you have just enough time to brake, maintaining steady speeds, and hwy at 70 or below are all part of it, but you can do it with out the ECO on which makes everything else work more normally. This is my last 10 or so fill ups average. I usually don't go to empty but fill up somewhere around 1/2 tank or when it seems best based on prevailing prices. Being retired gives more latitude there. This is a great app you can d/load for your droid.

Even though it has been only a few days since I turned ECO off, I can see a difference in when the ICE turns on and off. There is a very obvious increase in power from the ICE, but for my RX, the ICE turns off less consistently with ECO off. So far since I have filled up and turned ECO off, my avg mpg has slipped from 31.2 (ECO on) to 28.6, almost 3mpg less. Am I too quick to conclude the only factor for the reduced economy is because of the ECO mode turned off, or could it be that I am unconsciously enjoying the added power too much, or does the ICU need to relearn my driving habits now with the ECO mode turned off?

I have no specific knowledge of this, but I thought, perhaps incorrectly, that the car learned two different patterns. One for ECO mode and another with ECO mode off. When in ECO I make a more conscious effort to drive economically. With ECO off it's back to lead foot.
Does anyone know for sure?
