The Nissan Versa (sedan) and Nissan Versa Note (hatchback) are the stalwarts of the brand's subcompact effort. Enormous inside, and in the case of the Note, quite practical for cargo hauling, the Nissan Versa also happens to be the most affordable car on the market. The Versa benefits from a fuel efficient 1.6-liter, four-cylinder engine that generates 109 horsepower and 107 lb-ft of torque, and buyers can choose either a five-speed manual or a continuously-variable automatic transmission.
