HAHAHAHA - Yes, you are correct. I meant moot, not mute. Good catch on the spelling!

As far as adding 20% for the RX500h your logic is completely flawed. This thread is about the RX500h MPG (miles per gallon). Cost does not enter into that equation whatsoever. What you are referring to is fuel cost per mile. In that case a factor would be applied as you state, but the differences in fuel costs (premium to regular) varies widely in different areas. For an example in my area the difference is about 7%.

The real world information of 28.4 MPG shared by ktsaiktsai is exactly the information most of us were looking for.

I don't think this thread is about comparisons between the RX500h & RX350h as it has seemed to devolve to. There is a specific thread concerning RX350h MPG and people can compare as they wish. These two vehicles are dramatically different as it relates to their drivetrain.

 

The distance to empty calculation is off (or extremely conservative). As others have shared the tank is 17 gallons. In the next tank I’m driving past zero DTE and fully expect the RX to keep going. I really just want to affirm I can get 15 or so useful gallons out of the tank which translates into a minimum of 50 miles additional range beyond the 0 mile DTE.

Will share!

 

+1 comment. After 2200 miles my RX500 is @ 25.6 miles per gallon.

 

25.6mpg wow thats awesome!

 

Huh? That is awful. It equals 9.1 liters/100 kms. Our 3.5 liter V6 gets better than that. Surely there is something else going on.

 

Our RX 450h gets about 9.0l/100kms; the predicted mpg was predicted at 26/27 (or something like that) for the 500H.

 

(I couldn't edit my previous post)
Here's what I found reported on the internet:8.7/8.4 (CITY/HWY); 27 city/26 highway

Which is close enough for me.

 

Take that 3.5 V6 in city driving rush hour traffic...its gonna suck down gas

 

Absolutely, I am getting around 13-15 city MPG on 19 that v6, and HWY maybe 23-24MPG if you keep it under 65MPH, once you go past that it drops right down to about 21 MPG.

 

Yeah, my 500H got 27 MPG sitting in rush hour traffic bumper to bumper for 2 hours. Thats actually amazing.

 

Here are my results with my 500h after three tanks of fuel and 700+ miles so far:

RX500h in Eco Mode? 30 MPG. I was astonished as the sticker said 27/28 and I got higher. To be fair, however, I was driving around hilly roads near Ennis, Texas, (sightseeing the annual Bluebonnet fields) and usually didn't exceed 45 MPH.
RX500h in Normal Mode? 25 MPG. I drive this about 50% of the time. My commute to work is a 50-50 combination of city/highway driving.
RX500h in Sport Mode? 23 MPG. I drive this mode when I want to have a fun drive. (I have heavy foot, and I LOVE the acceleration....)

 

Just got our 500h, getting 24 mostly city driving so far under 300mi total

 

Sounds like reasonable conditions.

How are you driving it, and under what conditions?

 

Normal city driving in AZ ~ 98degrees, mostly short trips under 10 miles, min highway for short runs

 

I meant not conditions, but gas mileage, but you answered my question correctly.
Congrats on the new RX.

Enjoy
