On the ES350, does anyone know the expected difference in MPG between running on Eco v. Normal v. Sport? What are people's experience?

See my post in the Gas Mileage thread. I got my best results so far with the Sport mode. I wonder if it is too dependent on driving style to be comparable from person to person.

Don't really know about the difference in MPG, but I always drive my ES in Sport Mode. Normal or (especially) Eco modes just make the car too sluggish IMHO.

I'm averaging about 25.5 MPG in combined highway/city driving using Sport Mode almost exclusively.

With my ESh I tried Eco and the car is so sluggish it seems to stay in power mode longer just to gain speed. I have not tried Sport, but Normal seems a best combination of economy and power. I found the same thing on my RX450h.

Since I bought the ES300h on 8/15, I've tried ECO on one single tank of gas; I noticed my average MPG was 1 MPG higher using ECO, but like on my previous HS250, I feel I need more power on tap. So I went back to NORMAL, and I've averaged an overall 40.25 mpg with 1,950 on the odometer. (Most of those miles have been in city driving.)

I haven't even tried SPORT, since NORMAL seems quite spontaneous and plenty powerful for my driving needs.

I sure do love this car!

This actually makes sense. Getting up to cruising speed quickly after the ICE has come on assists in getting higher FE. I have found whether you accelerate slowly or briskly, FE is about the same. When you accelerate slowly, you are getting low FE for a longer period of time as compared to faster acceleration. Once at the desired cruising speed, FE jumps significantly and would be maintained for a longer period of time as compared to slower acceleration.

Wow I like this logic...and I'm gonna try SPORT mode. Sounds like I can have even MORE fun on those highway entrance ramps!
