Fuel cost and CO2
The file prices the fuel for its most efficient version at about $600 a year, assuming 15,000 miles a year with 55% of them in the city and electricity at $0.15 per kWh. That is $1,700 less than the small SUVs median of $2,300, which makes it tied for 3rd of 113 small SUVs, in the top quarter.
It has no tailpipe emissions, so the CO2 column is zero; the emissions from making the electricity are not part of this figure.
