In terms of environmental impact, the 2018 A3 e-tron produces approximately 150 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this A3 e-tron performs better than the national average in this regard.

The estimated annual fuel cost for this vehicle is $1,900, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would spend $3,250 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.
