The car that pioneered the hybrid movement and has defined fuel-efficiency for four model generations still stands tall as an innovative green machine. Its fuel economy in our tests was a staggering 52 mpg overall—the highest we’ve ever recorded in a car that doesn’t plug in. Prius also touts excellent reliability, a remarkable accomplishment given the inherent complexity of its hybrid powertrain. It has improved even more with its recent redesign, reducing cabin noise, improving ride comfort, and making handling more responsive. Sweetening the deal, the new Prius comes standard with a comprehensive suite of safety features. Being green has never been so easy or smart.
