GMC Hummer EV joins gas-guzzlers in list of meanest for the environment

Baua Electric

The 2024 American Council for an Energy Efficient Economy (ACEEE) list of “meanest” vehicles for the environment includes the expected array of gas-guzzling trucks—but also one EV. Worse yet, the Hummer EV may enable General Motors to build more gas-guzzling trucks. So it’s tread heavy and tread heavier.
