The 2013 Nissan Altima has been completely redesigned from the inside out for the 2013 model year, with more innovation and excitement than previous models. The new Altima has earned an IIHS Top Safety Pick+ rating, thanks to Nissan's Advanced Air Bag System that has dual-stage supplemental front air bags and seat-belt and occupant-classification sensors. The body of the new Altima features Zone Body construction with front and rear crumple zones, as well as hood buckling creases and safety stops. On top of that, the Altima has pipe-style steel side-door guard beams and an energy-absorbing steering column. If you haven't taken a look at the all-new Nissan Altima and its updated safety features, now is the time.
