About 2015 Nissan Sentra The seventh-generation Nissan Sentra continues to be refined for the 2015 model year with a number of interior comfort and convenience enhancements, including standard USB connection port and Bluetooth Hands-free Phone System on all models. In addition, leather-appointed seats and heated front seats are standard on Sentra SL, and rear disc brakes are now standard on Sentra SR and SL grades. Sentra's available NissanConnect with Navigation includes NissanConnect Apps smartphone integration for iPhone and Android, allowing the user to connect with Pandora, iHeartRadio, Facebook and more. The 2015 Sentra offers class-above design standards inside and out, as well as efficiency in engineering. The aerodynamic design allows Nissan to use a fuel-efficient 130-horsepower, 1.8-liter engine, along with the Xtronic CVT with sub-planetary gear helps deliver a 13 percent improvement in EPA combined fuel economy (versus the previous-generation Sentra). Sentra's exterior design is elegant, modern and refined, reflecting a "professional" character targeted at upwardly bound buyers who aspire to drive something more premium than some of the other designs in the segment. It adopts Nissan's bold signature trapezoid-shaped grille and large wraparound headlights with standard LED accents. In the rear, LED taillights are also standard, which complement the sophisticated styling. Along with offering midsize roominess in a compact-size exterior, the intuitive interior layout emphasizes driver control and outstanding seat comfort for all five occupants. The instrument panel curves out towards the doors and features Fine Vision electroluminescent gauges that are backlit even in daylight, providing a high-quality look that is also easy to read.
