Nissan unveiled the redesigned 2013 Nissan Sentra Friday, which received a complete interior and exterior overhaul, as well as a new engine.

Nissan says in a statement the 2013 Sentra delivers a “13 percent improvement in EPA combined fuel economy,” thanks to a weight reduction of 150 pounds, a new four-cylinder engine and Nissan’s next generation continuously variable transmission (CVT). Nissan says the redesigned Sentra gets 30/39 mpg city/highway for a combined rating of 34 mpg, though estimates are not yet posted to the EPA website. The 2012 Sentra with the CVT gets an EPA-rated 27/34 mpg.

The new 1.8-liter, 130-horsepower four-cylinder engine is smaller and less powerful than the 2.0-liter, four-cylinder base engine in the 2012 model, which makes 140 horsepower. A six-speed manual transmission is standard on the base 2013 Sentra S, while the CVT is available. Fuel economy estimates with the manual transmission are not yet available.

The new Sentra is slightly longer and narrower than the 2012 model. Though total interior space is about the same, Nissan says the redesigned Sentra offers more functional space. “The fine-tuning of its dimensions has created not only extremely well-balanced exterior proportions but enhanced rear seat legroom and created a larger, more usable trunk space,” said Al Castignetti, vice president and general manager, Nissan Division, Nissan North America, Inc.

Car and Driver reports that Nissan models like the Versa are larger than other affordable small cars, which should help Nissan boost sales. “Have any doubt that size sells? Look at the Versa: Unremarkable in virtually every category, underpowered, and cheap-feeling, it’s big and has a large back seat. And Nissan is on pace to sell more than 100,000 in the U.S. this year. Good thing, then, that the Sentra also is substantial inside.”

Standard features include a four-speaker CD audio system and a tilt and telescopic steering column. The 2013 Sentra can be equipped with features like dual-zone automatic climate control, Bluetooth, satellite radio, a USB port, a Bose sound system, leather-appointed seats, heated front seats, a moonroof, navigation, hands-free text messaging, a rearview camera, push-button start and Nissan’s Easy Fill Tire Alert system, which honks the car’s horn when you’ve filled the tires with the proper amount of air.

The revamped exterior has LED accented headlights, LED taillights and chrome door handles. “It also looks like the lovechild of the new Altima and a Lexus IS,” says Jalopnik. “And it's boring.”

Pricing hasn’t been announced yet, but the 2013 Nissan Sentra is expected to hit dealerships this fall.
