Tested accuracy of the GoM
We decided to drive to the mountain town of Woodland Park for combination Father's Day and anniversary. GoM showed 203 miles (sorry but I don't remember the SoC) and after driving 62 miles of stop and go, up hill, downhill and rain we pulled into the garage showing 141 miles. I'm surprised by the accuracy of the GoM.
I understand that I didn't take the car to 0% SoC to fully test the system but I am impressed. Overall efficiency was 29.5 kWh/100 miles so not bad. Didn't run A/C but climate was on, charged phone and headlights were on due to weather.
