The GMC Hummer EV SUV is rated 53 MPGe (59 city, 47 highway) — that is not petrol economy but the distance it covers on 33.7 kWh, the energy held in one gallon. Drawn from a socket it needs 63.6 kWh per 100 miles, so 12,000 miles a year costs about $1,297 at $0.17 a kWh. The EPA's own annual figure for it is $1,450.

Which Hummer EV SUV version is the most efficient?
The Electric at 53 MPGe.
Is the Hummer EV SUV efficient compared with similar cars?
Against other Electric cars it sits below the average of 101 MPGe, computed across 426 ratings.
Are these real-world Hummer EV SUV figures?
No — they are EPA laboratory ratings, the same ones printed on the window sticker, and EPA's own annual fuel estimate for the GMC Hummer EV SUV is $1,450 against the $1,297 we compute at 12,000 miles. Expect a little worse in practice: the spread between the city and highway figures is smaller than the spread between two drivers of the same one.
