Where it stands
Compared only with the electric models of its class it is 7th of 7 electric compact cars, in the bottom quarter. The median of that narrower group is 93 MPGe, against 34 MPGe for all compact cars together.
Among all electric models of the year, regardless of size, it is 61st of 66 electric models, in the bottom quarter.
In its class, just ahead of it is the Audi RS e-tron at 84 MPGe and just behind it is the Toyota Corolla Hybrid at 50 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
At 15,000 miles a year with 55% of them in the city, with electricity at $0.15 per kWh, the annual fuel bill of the most efficient version is about $1,000. That is $950 less than the compact cars median of $1,950.
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
Its city rating is 74 and its highway rating 82: the highway figure is 8 higher. 4 versions are rated for 2026. The most efficient, Spectre (22 inch Wheels): electric motor, Automatic (A1), AWD, gets 77 MPGe; the least efficient listed, Spectre Black Badge (23 inch Wheels): electric motor, Automatic (A1), AWD, gets 70 MPGe, a gap of 7 MPGe. With the file's assumptions that gap is worth about $100 a year in fuel.
