Nissan Sentra is powered by a four-cylinder engine that reviewers wrote provides decent power around town. However, like many small cars, they said it strains when accelerating for highway merging or passing. Auto writers reported that shifts feel clunky with the standard six-speed manual transmission. Some reviewers thought the available continuously variable transmission (CVT) makes good use of the engine’s power, while others said it can be annoyingly loud at high speeds. Equipped with the CVT, Sentra gets an EPA-estimated 30/39 mpg city/highway, which is excellent for the class. Some critics said that agile handling isn’t the Sentra’s strong suit, though others thought it handled curves with admirable body control. While test drivers agreed that the Sentra delivers a comfortable ride, many said the steering doesn’t offer much feedback, and that the Sentra isn’t as fun to drive as some rivals.
