4. Toyota Prius
1997 — present
The original 1997 Prius was an odd-looking duck, but subsequent models have looked even more unusual. Its style is the result of the need to have a super-slippery body — the easier it glides through the air, the less aerodynamic drag brings down its fuel economy. But the Prius’ polarizing properties stem as much from its social statement as its styling, with ownership bringing an environmental cachet with it that some find righteous and others find intolerably smug. Toyota sells a quarter million of the compact hybrids a year in the United States alone, so plenty of people must find them suitable.
