figured Id share this since I I took the time to plot the data.
But this is on my 2010 Traverse.
I live in Los Angeles- and I do city and rush hour every morning and afternoon. Normally I see 18-19 MPG combined.
With people still on holiday travel- traffic has been easy-- so at the moment- im at 21 MPG (DIC). My hand calcs usually come within .5 to 1 MPG from the DIC.
went for a quick drive around the neighborhood---plotted this data-
starting with the blue line--- at about -77 (77 seconds since I began to log)....
I came to a complete stop--- as shown by the red-- 0 MPH in the 2nd graph...
I proceed to easily accelerate-
1-2 shift about 1850 RPM at about 10.5 MPH- continue to accelerate
2-3 shift about 2230 RPM at about 21 MPH- continue to accelerate
3-4 shift about 2200 RPM at about 33 MPH-
where I then reach a peak - about34 MPH--- yes 34 MPH in 4th gear...-- watching traffic down the street I notice theres a red light... no need to accelerate -- So I let off the gas...
where you can see it takes me about 25 seconds to go from 34 MPH to close to zero...
THe important point here is that I let the vehicles momentum roll me for 25 seconds- to the light that was red... were I simply coasted- and once there accelerated from a moving start... not a complete stop
As you can see in this short trip that lasted about 2 min- I never exceeded 2500 rpm.
I try to keep all my driving this easy- where conditions allow me to easily do this...
if traffic gets heavy- I follow the traffic speed....
tommorrow ill graph engine temp vs RPM vs vehicle speed...
