The American Council for an Energy-Efficient Economy (ACEEE) has panned “the worst-performing mass market automobiles” marketed in the United States in 2024, and it has no qualms about it on its so-called “Meanest List” of twelve models.
It is a gas-powered vehicle, and its MSRP is almost $184,000.

*ACEEE analysis based on 15,000 miles driven annually on EIA data.
The only electric vehicle on the list, the 9,000-pound GMC Hummer EV, is lonely toward the pack’s center.
It is also important to remind potential purchasers that “demonstrating that greener solutions can also be more inexpensive,” the average gasoline cost of a car on the “Greenest List” is only one-fifth that of a car on the “Meanest List.” Additionally, the ACEEE released a “Greener List” of fuel-efficient and plug-free hybrid and gasoline-powered vehicles.
