Where it stands
Compared only with the electric models of its class it is 3rd of 5 electric large cars, in the upper half, ahead of 50% of the others. The median of that narrower group is 98 MPGe, against 28 MPGe for all large cars together.
Among all electric models of the year, regardless of size, it is tied for 35th of 66 electric models, in the lower half.
Within the 22 Mercedes-Benz models rated for 2026 it is 2nd on combined rating; the median of the make's line-up is 25.5 MPGe.
In its class, just ahead of it is the Tesla Model S at 124 MPGe and just behind it is the Dodge Charger Electric at 95 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
The file prices the fuel for its most efficient version at about $750 a year, assuming 15,000 miles a year with 55% of them in the city and electricity at $0.15 per kWh. That is $2,200 less than the large cars median of $2,950.
It has no tailpipe emissions, so the CO2 column is zero; the emissions from making the electricity are not part of this figure.
