2013 Nissan Sentra: improvement in fuel efficiency and forward in style
The new edition of Sentra steps forward in style, sophistication and refinement as well as presenting an improvement in fuel efficiency.

Technicians of the Japanese firm did not only focus on bringing the 2013 Sentra to another level with regard to comfort and aesthetics, but also made a strong work in the technical section.

To achieve this we installed a new 1.8-liter engine and 130 HP that is coupled to a Xtronic CVT transmission (S version offers an optional six-speed manual), it optimizes both performance and efficiency. Another contributing factor is the reduction in weight of 150 pounds by the use of ultra-light materials.

The exterior design combines modernity and elegance, offering the public an image of self more "premium" than its competitors in the segment. Excels new Nissan grille and LED headlights both front and back. Additionally your waistline has been reduced to give it a more aggressive look.

Inside using high quality materials that are not common in a compact car. To this is added a larger space that provides a superior level of comfort (more legroom in the second row of seats in its class). Its dual zone climate control systems found, audio system with four speakers (Bose Premium with eight speakers optional), 4.3-inch display, USB for iPod, Bluetooth and SiriusXM Satellite Radio. Another novelty of the 2013 Sentra is NissanConnect navigation system controllable from a 5.8-inch touch screen.
