Where it stands
Compared only with the electric models of its class it is 16th of 17 electric standard SUVs, in the bottom quarter. The median of that narrower group is 96 MPGe, against 22.5 MPGe for all standard SUVs together.
Among all electric models of the year, regardless of size, it is 55th of 66 electric models, in the bottom quarter.
In its class, just ahead of it is the Cadillac VISTIQ at 86 MPGe and just behind it is the Mercedes-Benz G-Class Electric at 62 MPGe.
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 $900 a year. That is $2,475 less than the standard SUVs median of $3,375, which makes it tied for 15th of 90 standard 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.
Rated versions
The city rating of 94 is 17 above the highway rating of 77. 25 versions are rated for 2026. The most efficient, R1S Dual Large (22in): electric motor, Automatic (A1), 4WD, gets 85 MPGe; the least efficient listed, R1S Quad Max (20in AT): electric motor, Automatic (A1), 4WD, gets 67 MPGe, a gap of 18 MPGe. With the file's assumptions that gap is worth about $250 a year in fuel.
