Compared only with the electric models of its class it is 5th of 5 electric standard SUVs, in the bottom quarter. The median of that narrower group is 78 MPGe, against 29 MPGe for all standard SUVs together.
Among all electric models of the year, regardless of size, it is 17th of 17 electric models, in the bottom quarter.
In its class, just ahead of it is the Audi SQ8 e-tron at 70 MPGe and just behind it is the Lexus TX Plug-in hybrid at 29 MPG.
Electric models use no fuel and have no tailpipe CO2. Efficiency is given in MPGe, the miles driven on 33.7 kilowatt-hours of electricity, which is the energy in one gallon of gasoline. The annual cost is electricity at $0.15 per kWh.
Fuel cost and CO2
Assuming 15,000 miles a year with 55% of them in the city and electricity at $0.15 per kWh, fuelling the most efficient version comes to about $1,450 a year. That is $1,400 less than the standard SUVs median of $2,850.
It has no tailpipe emissions, so the CO2 column is zero; the emissions from making the electricity are not part of this figure.
