I don't think anyone can drive in the ECO bar. I have tried and thought the same thing... it's broke! Or I should say if you do everyone behind you will HATE you.

Really? Oh man. I drove one around for a bit and my average was about 37.. I guess that's still at LEAST 50% better than the GS though haha

I have explored all four settings. My gas mileage is identical with each one.

Im getting 16.7 MPG mainly city-
90% of the time car is in ECO mode.

I wouldn't say so, I drove in S and S+ aggressively, and a full tank lasted 4 days lol.
In ECO mode full tank lasts me 7-8 days.

Idk how you're driving in ECO mode in this scorching heat. Besides the reduced responsiveness, I can't stand how it dials back the A/C.

I drive like a grandpa. You will probably spot me on the road

I had a fairly long road trip a few weeks ago and managed almost 27mpg on my return trip, and I was averaging 75-85mph. Not "great" (depending on your expectations), but very reasonable in my opinion given the trade-offs (size of vehicle, comfort/luxury, etc). Wife normally hates long road trips but said it flew by, which speaks volumes to the comfort. I see more summer treks coming

WOW! THAT SUCKS! You mine as well be in Sport or Sport+ with mileage like that.

I have noticed the gas mileage stretching, just a bit, as the car breaks in. I'm at around 1300 miles now. I am usually tripped around 60 miles by the time I reach 3/4 tank....I don't typically drive like a grandpa because I live in South Florida and driving like that will get you run over or run off the road down here; however, I am not flooring it either. On this tank (since I last posted here), I have been really babying the pedal and I am still experiencing the same mileage.

On a side note, we are getting worse gas mileage compared to what I got in my '10 535i - and that was a twin turbo v6 motor!

I think we need to, collectively, write letters to Lexus and complain we are not seeing the advertised mileage. I still have my window sticker that says "23 mpg city" and I am not seeing anywhere near that no matter how I drive.

Just my $.02.

Thanks for listening.

You can change that if you pick up a VCI cable.



On my car I flipped that setting and the auto seat heater dial down ('13) among others.

Eco mode should give u only 1-2 miles difference. U can change the AC settings to full blast in Eco mode with the Carista app too but I think it would defeat the purpose of Eco.

I get 23 MPG every tank in ECO mode with Switching to S/S+ mode a couple times per tank.

60% city
40% highway

RLtoGS350

I get the same with about 70/30 city to highway. I knew going in that this car wouldn't be more than that especially with the option of Sport & Sport+ so no disappointments here.

Drove in Eco mode for a day yesterday and got 16-17 MPG, Sport + all day today and got 18 MPG. Da hell?!

I'm not my 3rd week and 4th tank of tank after I bought my car. MPG has increased from 16.3 to 17.6 average MPG. I guess the car needs to break in a bit. I also been driving more on sport and sport+ mode.
