Redesigned 2013 Nissan Sentra sedan revealed

Nissan has lifted the cover off the redesigned 2013 Sentra sedan—its third product reveal within the past six months. The new Sentra arrives in dealer showrooms this fall.

Nissan says the new Sentra is lighter by 150 pounds and more fuel efficient, returning up to 40 mpg highway.

It comes equipped with a new 1.8-liter engine rated at 130 hp and 128 lb-ft of torque. Most Sentras will use a continuously variable transmission. A six-speed manual is available in the base S model.

From a styling standpoint, the new Sentra looks a lot like the larger 2013 Altima. Trim levels consist of the base model S, SV, SR and top-of-the-line SL.

The new Sentra is a bit longer and gains 0.6 inch in its wheelbase. But the car is narrower and doesn't stand as tall, which helps cuts wind drag to 0.29 from 0.34, seen in the last generation.

The Sentra marks 30 years in the market with the 2013 model.
