The New Car Assessment Program (NCAP) of the National Highway Traffic Safety Administration gave the 2013 Nissan Altima a five-star rating (from a maximum of five). A four-star rating was given to the last-generation 2012 Nissan Altima on the same test. The interior of the 2013 Altima has driver and front-passenger seat-mounted side-impact air bags, and roof-mounted side-impact curtain air bags. It also features blind spot monitoring and lane departure warning systems. Of course, the 2013 Nissan Altima isn’t the only midsize sedan to be given five stars on the NCAP test. Other models that earned the rating are the 2013 Chevrolet Malibu, 2013 Hyundai Sonata, 2013 Kia Optima, 2013 Toyota Camry, and 2013 Volkswagen Passat. Vehicles that earned four stars are the 2013 Chrysler 200, and 2013 Dodge Avenger. The NHTSA has not rated the all-new 2013 Ford Fusion and 2013 Honda Accord so far. The 2012 Ford Fusion got four stars. Meanwhile, the 2012 Honda Accord was given five stars. The Insurance Institute for Highway Safety hasn’t yet given the 2013 Nissan Altima sedan a rating. The IIHS said last August that it will test the new Ford Fusion, Honda Accord, and Toyota Camry next.
