- 2022 Polestar 2 BEV - Current, 2021 Q5 55e PHEV - Retired, 2015 Q5 3.0 TDI - Retired, 2013 Golf TDI - Retired

Because I like to torture myself with math and wanted to see what the long term environmental impact of this is:

My TDI --- My Fuelly Data

Best MPG Ever - 32.8 MPG --- CO2 per mile 305.94 grams

Average MPG - 27.3 MPG --- CO2 per mile 367.46 grams

Worst MPG - 23.8 MPG --- CO2 per mile 421.49 grams

PHEV 55e ( Extrapolated from 3 Owners of 2020 Q5 PHEV on fuelly )

Best MPG Ever - 84 --- CO2 per mile 104.61

Average of 3 - 53.7 --- CO2 per mile 163.54

Worst of all users - 35.5 --- CO2 per mile 247.4 grams

Now I understand CO2 figures don't count the electricity. ( Our electricity in our city is 100% renewable sourced ). But assuming for easier math that the electricity is carbon free, even the worst case is a 32.67% reduction in CO2 over my average, and the avg vs the avg is a 56% reduction.... thats amazingly good. I guess it all comes down to if you manage the battery and such... I mean if you take a highway trip in it, and it gets the rated 29 mpg, and you go 49 miles, that assumes you got 20 miles of electric range and 29 miles of batterty range... that means you averaged around 49 mpg... so not really far off the average of the 3 users... so as long as you recharge the capacity this seems like a win win, and even over what looks like longer trips their getting good mpg figures....
