2012 Lexus RX 350

 

Mine is about 27mph. why you ask?

 

Huh? Strange. Mine goes faster.

 

I worked in five states and moved - drove - across the country accordingly many times. I have done Nashville to Seattle 6 times.
It takes a LOT of FWY driving to get average speed to 50 or 60. Hrs and hrs. At steady speed way higher than that.

 

Differently cool average to work with is the MPG average. On the Navigation or
Display Audio screen under "Info" is Fuel Economy. Open it and see Past Record
and Trip. (Hybrids also have Energy...different thread) When you press the steering
wheel menu button(s) and display Average MPG in the Driver Information Center between
the Speedometer and Tachometer (Power Meter in a Hybrid) you can then "reset" it. Watch
the graphic on the main screen move the graph to the left and display the current date!

We reset the MPG four times a year on the seasons. Easy to see the last year and a
half, lower MPG in the winter, higher in the summer. Left without resetting this graph will
display up to 9999 miles and then become a "rolling average" of the last 9999 miles.
Note that the DIC also has a Tank Average that can not be reset. It resets itself when
you fill the tank. No need to write down the mileage, reset the trip odometer(s) and fiddle
around with the readings! Try resetting before a high speed journey (along with the OP's
average MPH) and discover the difference between stop and go vs. highway. Reset before
allowing a teen driver out on a hot date..."really? 62 MPH and 13 MPG?!"

 

much ado about nothing.

I dont think any one needs a lesson on how to calculate average?

All those "0" mph at standstills brings the average speed down. If might be a new realization for some, but the manufacturers have been devising ways to shut the engine while stopped to boost the MPG (another average NOT "saved by zero" )
