Often thought of as a happy medium between the Altima and Maxima, the Sentra undoubtedly has mass appeal. Its squared front-end looks quite intimidating. Under the hood is a four-cylinder engine that is paired to an automatic transmission. The vehicle achieves a splendid 29/39 mpg. Options range from standard Bluetooth to an 8-speaker Bose sound system, navigation, the NissanConnect infotainment system, a proximity key and a 5.8 inch touchscreen.
