Frequently asked questions

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.
