In the world of hybrids, the undisputed king is the Toyota Prius. Now in its fourth generation, the Prius basically invented the hybrid class when it first debuted in 2000 and it has been the best-selling hybrid in America ever since.
Today Toyota offers the Prius in three distinct models: the subcompact Prius C, the best-selling Prius hatchback, and the Prius Prime, which is a plug-in hybrid. Introduced in last year, the Prius Prime is the same size as the standard Prius hybrid and it competes with the Chevrolet Volt and plug-in hybrid versions of the Honda Clarity, Kia Niro Plug-In, and Hyundai Ioniq. Many buyers are turning to plug-in hybrids because they offer the best of both worlds: A fully charged plug-in hybrid can be driven emissions-free on pure electricity like an electric car, but with the help of a small gasoline engine, they can be refueled at any gas station for extra range.
