I've poked around with Torque with this car and it doesn't offer anything beyond basic telemetry like road speed which didn't vary at all from what the onboard system was showing me. The i3 PIDs really just aren't documented enough yet to get anything usable from it, so raw fuel consumption seems the only accurate way to gauge it right now. There is zero information available about range extender parameters. Even that is a little tricky as sometimes the range extender run time is outside of driver control, so I have to work within the parameters they have setup - which is fine since I understand them fully and can compensate appropriately.

I did do a bit of a baseline run using it this afternoon with the same 15-17 mph head / tail winds. 46.7 miles @65 using 1.65 gallons for 28.3 MPG kinda sucks in comparison to how efficient this car and others are otherwise, but it's a start for testing things at least. The wind seems more typical than not around here, so I may just try to utilize it for future tests instead of holding out for more perfect conditions.
