I just test drove one and love it but couldnt figure out how to make the gauge that shows the mpg average to reset to 0 so I could test on a short run. Finally salesperson and I found it on the big screen options and we reset it.

Then I drove for about 8 minutes in standard city traffic, using the adaptive cruise to self-drive as much as possible, which also has a very light foot from stop and so it is going to be the best mileage you can get I think, 70 degrees outside, etc.

Best I could get is 30.4 and the sticker says city 41 highway 37. Anybody else have some numbers?

I was in ECO mode, yet I am now reading for city driving NORMAL may be better, anyone try that?

 

Had the car about 3 weeks / 1.5 tanks. Rolling average is 37. I assume it will get better as it is broken in and warmer weather arrives.

 

Great to hear for you, based on what I saw driving this one there’s no way I would ever get to that unless it was flat road going a steady speed. Thanks for responding.

 

A couple misconceptions here:
A light foot does not equal to better gas mileage, it is certainly better than a heavy foot. However, the best way to achieve optimal gas mileage is to push the gas deep into the striped ECO power band (the solid ECO power band being the one where you're in EV mode), almost hitting the white power band itself. After reaching your desired speed in that power band, then coast/cruise in the solid ECO power band. I've personally achieved better than advertised EPA estimates regardless of weather, aside from snow or heavy flooding.

Cruise control does not enable the 350h to go into EV mode where it can accelerate/cruise on battery power.

Letting the 350h coast too long will be detrimental to your MPG overall as the regenerative braking from the traction motor will cause the vehicle to slow down faster compared to a nonhybrid engine, almost like it is engine braking in a higher gear. I've used this to my benefit by braking less overall on highways.
Overall, with mixed driving styles (hyper mileing, heavy footed) I average about 40 MPG this winter in NYC. On less chilly days (around 45 degrees and up) I average about 45 MPG

Nice

 

Cruise control disables the EV ability even win slowing down and not applying accelerator? That’s terrible news, I use cruise control constantly whether I am going 3 miles an hour or 70.

 

I got 37 on the first tank mixed city/highway driving. Cruise control does not disable the EV function. The little green EV icon is constantly turning on and off based on driving conditions whether in cruise control or not.

 

I should clarify that I only use cruise control on the highway, so the EV is not capable enough to maintain speed above 47~ MPH, so you'll have the engine running the entire time. It can for the most part maintain speeds in EV mode under that.

 

Even when not in the formal EV driving mode at highway speeds EV is still operative at any speed. The engine will turn off and on many times during a trip based on the current driving conditions. At the end of a trip a display shows what percentage of the time you are using EV which means the engine is turned off during that time. The little green EV car light comes on each time this occurs.

 

I’m aware of that. OP was asking about cruise control.
It's also why I said this in my original post "best way to achieve optimal gas mileage is to push the gas deep into the striped ECO power band (the solid ECO power band being the one where you're in EV mode), almost hitting the white power band itself. After reaching your desired speed in that power band, then coast/cruise in the solid ECO power band."

 

OK, thanks everybody I think I understand now. Accelerating deep into the striped eco-power band something I have not tried before I will try that, thanks. And I use the adaptive cruise control always, so I was worried there for a minute ha ha.

When I say “use”, I have not bought this car yet but my wife has a 2021 Lexus UX 250 H & while she does not trust the adaptive cruise control, when I drive I use it.

 

I'm around a 45mpg tank average. 70s-80s degrees for weather and a mix of highway and city driving.

 

 

can you tell how to reset it on big screen?
thanks!
