In terms of environmental impact, the 2018 M550i xDrive produces approximately 454 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 M550i xDrive has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $3,650, based on 15,000 miles of driving per year and current national average fuel prices.
