Frequently asked questions

How much does it cost to charge a GMC?

It depends on the model and your state. At the US average of 19.42 cents per kWh, a full charge ranges from $39.42 for the GMC Sierra EV to $39.47 for the GMC Hummer EV Pickup. In Nevada the cheapest of those falls to $26.61; in Hawaii the dearest reaches $107.13.

Which GMC is cheapest to run?

The GMC Sierra EV, at 49.5 kWh per 100 miles — $9.61 per 100 miles at the national average rate. The GMC Hummer EV Pickup uses 63.9 kWh per 100 miles, which works out at $12.41.

Is charging a GMC at home cheaper than a petrol car?

In almost every state, yes. A petrol car at 30 mpg and $4.09 a gallon costs about $13.62 per 100 miles. Every GMC here beats that at the national electricity average — the individual model pages name the specific states where high electricity prices close the gap.

Do these figures include charging losses?

Yes. Consumption comes from the EPA combined rating, which is measured at the wall socket, so energy lost in the charger and cabling is already counted. No extra efficiency factor is applied.
