10. Hummer, 2010
Few car companies were devoted to environmental destruction quite like Hummer. Sure, practically all automakers build one or two vehicles that are unnecessarily thirsty but every single product foisted on unsuspecting customers by GM’s SUV brand was practically guaranteed to return single-digit fuel economy (maybe gallons per mile was a more appropriate measure). They may as well have burned tires instead of gasoline.
The brand’s product portfolio consisted of brick-like utility vehicles including the ginormous H2 and the slightly smaller though no less awful H3, each of which had the aerodynamics of a city-sized meteorite screeching toward earth. Hummer was the automotive equivalent of a codpiece, it made you look big even if you weren’t
In the end a Chinese firm attempted to purchase this doomed brand from GM as it went through bankruptcy but that deal was nixed by the government… the Chinese government. As a result Hummer got tossed in the trash like an apple core, but unfortunately this piece of garbage wouldn’t even make good compost.
